Summary:
Based on the text you've provided, it seems like there might be some confusion or misunderstanding in interpreting what "Start SmartConnector" actually means and how to perform this action. Typically, starting a syslog SmartConnector in a cluster environment involves setting up and configuring the connector to handle remote management properties for logging events across different nodes in the cluster. Here's a more detailed breakdown of the steps involved:
### Understanding "Start SmartConnector"
The term "SmartConnector" refers to a software component that facilitates communication between different devices or systems within a network, especially when managing and monitoring log events. In this context, starting the SmartConnector means initiating this connector so it can take on its designated role in the cluster setup: collecting and forwarding syslog messages from various nodes to a central server (in this case, 10.20.1.55 with port 443).
### Steps to "Start SmartConnector"
1. **Open a New Window**: You need to open a terminal or command prompt window on the appropriate node where the syslog SmartConnector is installed and configured. Ensure you have the necessary permissions to start, stop, and configure network services.
2. **Run Command**: Execute the command `/etc/init.d/arc_syslog_udp_1 start` in your Linux environment (the exact path might vary depending on where it's installed). This command is used to initiate the syslog SmartConnector service which will then proceed to listen for incoming syslog messages based on the configured properties and IP address settings you have provided.
3. **Monitor Connector Startup**: Keep an eye on any log files or output from your terminal that indicate whether the connector has started successfully, especially checking if it's listening on the specified IP address (10.20.1.55) and port (443). You can also check this by looking for events in the syslog messages indicating successful connection to the central server or any error logs that might give you a heads-up about what could be going wrong during startup.
4. **Stop Connector**: If you need to stop the connector at any point, you would run `/etc/init.d/arc_syslog_udp_1 stop`, which tells the system to shut down the syslog SmartConnector service gracefully or forcefully depending on its setup and configurations. This might be necessary for troubleshooting or maintenance purposes before restarting it later when needed.
5. **Continue Setup**: After ensuring that the connector has started successfully, you can press (or any equivalent key) in your terminal interface to proceed with the next part of the setup process where you will configure remote management properties and potentially perform other cluster resource setups as outlined earlier.
### Additional Considerations
- **Cluster Resources**: Ensure that all necessary cluster resources such as `ClusterData`, `ClusterFS`, and `ClusterIP` are up and running before starting the SmartConnector, since this setup might depend on these resources to function properly. - **Configuration Files**: Review and modify configuration files like `agent.properties` or similar within your connector's installation directory (`/cfs/connectors/syslog-udp-1/current`) according to any specific requirements or changes needed for the SmartConnector service during its startup phase. - **Error Handling**: Be prepared to troubleshoot issues that might arise from misconfigurations, network problems, or other technical glitches during the connector's initialization process by checking logs and verifying settings manually as needed.
By following these steps, you should be able to start your syslog SmartConnector and continue configuring it further according to your cluster management requirements. If you run into issues or need more detailed information on any part of this setup, refer to additional documentation, manuals, or support resources that come with the connector's software package or check online forums/community support platforms where users who have implemented similar setups can provide advice and assistance based on their own experiences.

This document provides instructions for configuring and operating a Pacemaker cluster using HP products, specifically focusing on HP's ArcSight SmartConnectors. The setup includes configuring specific components of the Pacemaker system as well as monitoring and troubleshooting procedures. Key tasks include configuring Pacemaker itself, setting up ArcSight SmartConnectors, managing remaining Pacemaker services, starting/stopping connectors, resolving DRBD split-brain situations manually, monitoring syslog events, and troubleshooting common issues.
The article discusses the lack of inherent High-Availability (HA) capability for ArcSight SmartConnector installations beyond HA management through multiple Connector Appliances. When a specific SmartConnector or its system fails, traditional customers have relied on hardware load balancers for passive connectors like syslog, SNMP, but this only works for such connectors and not active ones like Windows or Database readers. Active connectors require manual failure recovery to maintain event collection service. While commercial clustering technology can be used with tools like Veritas Cluster Server, it involves significant capital investment. The article introduces the use of open source clustering software to create a low-cost, reliable, HA environment on CentOS Linux for running both passive and active SmartConnectors, providing automated failure recovery.
This package provides an availability environment for running both passive and active SmartConnectors, ensuring active failure recovery and service continuance. It is intended for informational purposes only and is not endorsed or supported by HP Enterprise Security Products. The setup involves automating a cluster creation from scratch using CentOS repositories or local customer provided ones, requiring a Linux binary of the HP ArcSight SmartConnector software that isn't included in this package.
The quickstart script will set up a functional cluster with a syslog SmartConnector capable of fail-over to a partner node upon primary node failure. Each of the two cluster nodes must have at least two network segments, although traffic can be on any customer network reachable via standard IPv4 routing. The cluster operates as a distinct IP node on the customer network and does not operate in-line.
The setup process takes less than 15 minutes with fast internet access or internal servers for CentOS repositories, but one should plan to spend time reviewing the configuration details, commands, and operating procedures. Recovery from incorrect operations may require a cluster outage. It is recommended to use two pairs of nodes (four nodes total) for both test and production clusters using modest VMware or other virtual servers. Care must be taken in choosing unique multicast addresses for the cluster to avoid collisions.
The document outlines a clustering solution using Corosync with specific components including CentOS 6.4, Corosync 1.4.1, DRBD 8.3.15, Pacemaker 1.1.8, PCS 0.9.26, and HP ArcSight syslog Daemon SmartConnector 6.0.5. The solution is designed to be installed on two 64-bit Quad Core Intel servers with 4GB memory each, equipped with two internal disks (one for OS and one dedicated cluster use) and at least two network interfaces (eth0, eth1). The configuration does not require more than two nodes initially but suggests adding a future version addressing node counts greater than two. It emphasizes the importance of multiple network connections to avoid split-brain conditions and mentions that dedicated raw disk partitions are required for the cluster, which can be on the same disk as the OS if necessary. This solution does not cover STONITH (Shoot The Other Node in the Head) solutions, focusing solely on a two-node setup at this time.
The document outlines a method for setting up an Active/Passive clustering solution using two servers with specific configurations:
1. **Network Configuration**: Each server has its own dedicated IPv4 addresses for network interfaces, along with a Virtual IP (VIP) for the cluster. At least one cross-over cable is recommended to connect internal network interfaces between the two servers; however, a management network switch connection can also suffice.
2. **Authentication and Access**:
Root public keys are used for authentication, allowing both nodes to remotely execute commands as root without requiring passwords. These keys are generated by a quickstart script provided in the tool.
Both servers have Internet access to CentOS software sites or use modified local/internal YUM repositories containing required packages.
The user must be an existing HP ArcSight user since the Linux SmartConnector binaries are not included with this tool.
3. **Limitations and Assumptions**:
This version of the document focuses on implementing a basic Active/Passive cluster without additional network-based or shared disk components, suitable for two servers.
The user is expected to have expertise in IPv4 networking, Linux OS administration, and general knowledge of clustering concepts.
**Known Limitations**:
Currently configured as an Active/Passive setup; future versions aim to support Active/Active configurations but with limitations on maximum load distribution (100/0 or 50/50).
No graphical user interface is provided for cluster management, relying instead on command line scripts for common tasks like starting, stopping, and fail-over operations. A web interface is available to display the operational status of the cluster.
The document also directs users to external resources such as linux-ha.org and clusterlabs.org for additional learning materials on clustering concepts.
The passage discusses a method for installing and configuring SmartConnectors within a Linux environment, specifically focusing on deploying them in a clustered setup with high availability (HA) capabilities. Here's the summary of key points from the passage:
1. **SmartConnector Deployment**: SmartConnectors are installed as a single instance with a VIP (Virtual IP Address) and a filesystem that follows the active cluster node for maintenance purposes, necessitating an outage for maintenance like upgrades. Multiple instances can be installed to load-balance via ldirectord functions for rolling upgrades in future versions.
2. **Performance Considerations**: The performance of SmartConnector should not be affected by using a DRBD (Distributed Replicated Block Device) based filesystem due to minimal disk I/O requirements during normal operation. If caching events are necessary, the effective performance is likely lower than with direct attached local disks but still acceptable for such use cases.
3. **Upgrades and Maintenance**: There's no specific guidance provided on how to upgrade cluster components directly in this paper, though future versions might address this. Upgrading the underlying OS involves ejecting a node from the cluster, applying updates, and re-inserting it. It's recommended to test changes in a lab environment before deployment to production setups.
4. **Security Features**: Current security features such as SELinux and iptables are disabled due to the paper’s focus on other aspects. The authors will document required ports and recommend firewall rules in an upcoming version, assuming the network segment is secure.
5. **Installation Process**: Detailed steps for installing and configuring the CentOS 6.4 operating system on both nodes (sy) are provided as follows:
Install and configure CentOS 6.4 OS on each node.
Overall, this passage outlines a method for setting up SmartConnectors in a Linux cluster environment with specific considerations for performance, maintenance, and security setup, while also acknowledging the need to improve guidance around upgrades and advanced configurations like firewalls, which will be addressed in future versions of the paper.
The provided text outlines a configuration procedure for setting up a system with specific requirements for an ArcSight installation. Here's a summary of the key points:
1. **System Configuration**:
A "Minimal Server" configuration was used, which includes only essential services. This setup does not include root passwords or IP addresses in the default configuration.
2. **Disk Layout for ArcSight Connectors**:
A custom disk layout is created to reserve a plain Linux partition (e.g., /dev/sda3) specifically for the ArcSight connectors. This partition should be large enough to serve as cache and prevent data loss if upstream ArcSight nodes become unavailable. The example configuration uses partitions sda1, sda2, and sda3 with types and sizes specified:
/dev/sda1: Linux (0x83), 512MB, mount point /boot (ext4)
/dev/sda2: Linux LVM (0x8e), 19GB
/dev/vg_ca1/LogVol00: 18GB, mount point /root (ext4)
/dev/vg_ca1/LogVol01: 1GB, swap
A filesystem should not be created on the partition intended for DRBD (sda3), as this could interfere with DRBD's functionality. The partition should remain unallocated until after the OS installation to avoid any existing use signatures.
3. **Networking Configuration**:
Configure two network interfaces with manual IPv4 settings, setting up DNS servers and a default gateway on the primary interface only. The secondary interface is connected via a cross-over cable. Although graphical environment setup simplifies management, it is not necessary for the cluster components in this case.
4. **Post-Installation Configuration Steps**:
After the initial OS installation, several mandatory steps are required to support the quickstart script:
Create DRBD partitions on both nodes as described.
Manually set the date and time of the system, if necessary.
Install OpenSSH clients, as CentOS Minimal does not include these binaries by default.
These configurations are crucial for ensuring a stable and efficient setup for an ArcSight deployment, particularly focusing on data resilience through custom partitioning and network settings.
The provided text outlines a procedure for setting up a cluster using the crm package's `cluster-quickstart.sh` script on CentOS nodes (node1 and potentially node2). Here’s a summarized version of the steps and considerations:
1. **System Installation and Configuration**: Ensure that both servers are set up correctly with CentOS, meeting the prerequisites for cluster installation.
2. **Transfer and Extract Quickstart Tar File**: Move the quickstart tar file to node1 and extract it. This will create a directory containing all necessary scripts and configuration files needed for the setup.
3. **Gather Cluster Node Information**: Collect essential information such as IPv4 addresses, VIPs, multicast address, nodenames, Logger details, etc. Use the provided `.clusterinfo.sample` file to ensure no mandatory data is missed.
4. **Configure Servers**: Set up both servers according to the given requirements, ensuring they are ready for DRBD (Distributed Replicated Block Device) setup without any existing filesystem. The chosen partition size should be sufficient to hold connector packages and event cache.
5. **Run Cluster Setup Script**: Use the `cluster-quickstart.sh` script to initialize and configure the cluster. This script automates most of the setup, requiring minimal manual intervention beyond initial configuration.
**Key Points**:
Ensure no critical data is present on the DRBD partition as it will be overwritten during setup.
The process should take around 30 minutes or less once all necessary information has been gathered and servers are configured appropriately.
This summary captures the main steps for setting up a cluster using the provided quickstart script, emphasizing preparation and system configuration requirements.
To summarize the provided text, it outlines steps for setting up a cluster using a specific script and configuration file on two nodes (presumably servers). Here's a simplified breakdown of the instructions:
1. **Cluster Initialization**: The node with the lowest number will act as the initial cluster node, which involves running scripts and copying files to configure the cluster environment.
2. **Creating .clusterinfo File**: Navigate to the "crm" directory on one of the nodes (the first one mentioned). Copy a template or sample file to create a `.clusterinfo` file, then edit it with all necessary cluster details. Ensure this file is executable by running `chmod u+x .clusterinfo`.
3. **Running Cluster Setup Script**: Execute the "cluster-quickstart.shl" script from the same directory, following any prompts and troubleshooting issues if sections fail. This process must be completed successfully for subsequent steps to function correctly.
4. **Important Notices in Script**: The script warns about modifying system settings that could affect security features like SElinux and IPtables. It also mentions that the specified disk partition will be overwritten, potentially losing all data on it from both nodes. The script should only be run on one node initially; do not execute setup commands on the second node unless explicitly instructed.
5. **Interactive Steps**: At various points during the script execution, users are prompted to either proceed with a step, skip it, or quit the process. This interactive nature allows for immediate intervention and correction of issues if they arise during cluster setup.
6. **Checking Cluster Status**: For monitoring the cluster's real-time status, use the `crm_mon` command line tool or access an HTML page at `/status.html` in a browser after setting up the cluster.
This summary captures the essential steps and considerations for initializing and managing a cluster setup process as described in the text.
This is a summary of a command output related to a clustering system using Pacemaker and Corosync on Linux. Here's what it means:
The system has two nodes (ca1 and ca2) configured, both expected to vote.
There are 8 resources configured in the cluster, including Master/Slave Set for ClusterData, Filesystem, IP address management, an Apache web server, a monitoring service, and SmartConnectors for syslog and CEF data transmission.
The SyslogUdp1 SmartConnector is running on ca1, reading events from a specified syslog port and sending CEF data to a Logger 'SmartMessage Receiver'.
To safely move the SmartConnectors to another node in case of failure, use "pcs cluster standby {node1}" to place the current node into standby mode. This will transfer all resources to the surviving partner node after stabilization (usually 1-5 minutes). Then, run "pcs cluster unstandby {node1}" to return control to the cluster policy engine.
Resource commands like "pcs resource stop SyslogUdp1" can be used to start or stop specific services within the cluster while it's operational.
Upon node boot, Corosync and Pacemaker components automatically initialize, allowing the cluster resources to select a primary node and initiate service.
The provided text is a summary of steps and considerations related to setting up and configuring a cluster using a quickstart script. Here's the summarized information:
1. **Configuration of OS**:
Ensure `/etc/hosts` files are updated on both nodes with IP addresses and hostnames specified in `.clusterinfo`. This helps in avoiding DNS dependency.
2. **Hosts File Example**:
```plaintext
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.20.1.61 node1.acme.com node1 172.16.100.61 node1-mgmt.acme.com node1-mgmt
10.20.1.62 node2.acme.com node2 172.16.100.62 node2-mgmt.acme.com node2-mgmt
```
3. **Cluster VIPs and ArcSight Destinations**:
IP addresses for cluster virtual IPs (VIPs) and specific destinations like ArcSight ES are listed.
4. **SSH Key Generation and Distribution**:
Generate SSH keys for the root user on both nodes, exchange them to allow root access across nodes.
Commands:
```bash
node1# ssh-keygen -t rsa -b 2048
node1# scp id_rsa.pub root@node2:.ssh/id_rsa.pub.node1.root
node2# cd .ssh
node2# cat id_rsa.pub.node1.root >> authorized_keys
```
Repeat for the second node.
5. **Security Precautions**:
Avoid using SSH keys with blank passphrases to prevent unauthorized access via root user. Consider enforcing named user login before accessing the root account.
6. **Network Configuration**:
Disable network auto-configure services to avoid issues during cluster setup:
```bash
vi /etc/sysconfig/network: NOZEROCONF=yes
service network restart
```
This summary provides a concise overview of the essential steps and considerations for setting up a cluster using a quickstart script, emphasizing both configuration details and security measures.
The provided text outlines steps for setting up a clustering environment on Linux servers, focusing on security measures and essential package installations. Here's a summarized breakdown of the process:
1. **Update System Security Settings**:
It is crucial to disable SELinux (SELINUX=disabled) and iptables firewall settings due to potential security risks that could lead to system compromise.
Commands for disabling these features include editing `/etc/sysconfig/selinux` and turning off the iptables service with `chkconfig iptables off` and `service iptables stop`.
2. **Setup Network Interfaces**:
Configure network interfaces using static settings:
Edit `/etc/sysconfig/network`, setting `NETWORKING=yes` and `HOSTNAME=node1`.
Disable automatic configuration with `NOZEROCONF=yes` in `/etc/sysconfig/network`.
Set up specific interface configurations like `/etc/sysconfig/network-scripts/ifcfg-eth0` and `/etc/sysconfig/network-scripts/ifcfg-eth1`:
For `eth0`:
UUID, NM_CONTROLLED, HWADDR, BOOTPROTO, DEVICE, ONBOOT, IPADDR (172.16.100.61), NETMASK (255.255.255.0), and IPV6INIT (no).
For `eth1`:
UUID, NM_CONTROLLED, BOOTPROTO, DEVICE, ONBOOT, IPADDR (10.20.1.61), NETMASK (255.255.255.0), NETWORK (10.20.1.0), GATEWAY (10.20.1.1), DNS1 (10.20.1.251), DOMAIN (acme.com), and IPV6INIT (no).
3. **Perform Package Updates**:
Update all installed packages on both nodes using `yum update` to ensure the latest patches and drivers are applied.
4. **Install Cluster Packages**:
Install Corosync, Pacemaker, and DRBD from a third-party repository:
Corosync provides the heartbeat and cluster messaging layer.
Pacemaker handles cluster resource management.
DRBD synchronizes a shared disk partition for supporting a cluster filesystem.
Commands to install these packages are not explicitly provided in the text but would typically be executed as `yum install corosync pacemaker drbd`.
This setup is crucial for establishing a secure and functional clustered environment where multiple servers can share resources, manage network communications, and provide redundancy against service outages.
This text outlines the setup of a RAID1 network-based disk volume using DRBD (Distributed Replicated Block Device) to run a connector filesystem, along with several other components necessary for cluster configuration. It includes specific instructions and configurations required for setting up a Corosync/Pacemaker cluster on Red Hat Enterprise Linux 6 (RHEL6), including:
1. Installation of necessary packages such as ntp, pacemaker, corosync, pcs, httpd, wget via yum from the ELRepo repository to support DRBD and other utilities.
2. Installation of 32-bit compatibility libraries for SmartConnectors that may require it.
3. Configuration details for a cluster setup where resources like ClusterData, ClusterFS, ClusterIP, ClusterSrcIP, and ClusterStatus are managed with dependencies on each other and specific hardware configurations.
4. Setting up SyslogUdp1 to listen on the VIP UDP 514, which is configured to send events to a Logger SmartMessage Receiver.
5. Detailed descriptions of how these resources work together in the cluster setup.
6. Instructions for configuring Corosync, including updating its configuration file with unique multicast IP addresses and ensuring this address does not conflict across multiple instances on the same network segments.
The purpose of this setup is to provide a redundant and highly available system where all components are designed to be fault-tolerant and responsive, with each part dependent on others for functionality.
This document discusses configuring Corosync, a cluster management engine, for use in a production environment. The setup involves using multicast addresses and encrypted hashes for mutual authentication of nodes. Corosync is configured in its version 2 with features like `secauth` enabled, which requires setting up cryptographic ciphers (`crypto_cipher`) and hash functions (`crypto_hash`), such as SHA1 or AES256, to ensure secure communication between cluster nodes.
The configuration file for Corosync includes specific settings for interfaces used in communication, defining at least one interface with a multicast address (e.g., 239.255.1.1 on port 4000) and setting the TTL (Time to Live). It also involves configuring `rrp_mode` as passive to manage resource replication protocols effectively.
Authentication keys are crucial for node authentication; Corosync allows generation of a unique authkey file, which is typically generated directly from the system console rather than through SSH terminals due to its security requirements. This key should not be hard-coded and must be securely managed in production environments.
The document also outlines steps to install the corosync configuration file on both nodes, start Corosync service on each node, and run a test for configuration validation before proceeding with cluster deployment.
The provided output from `corosync-cfgtool -s` indicates that Corosync is running properly with two rings active without any faults. Each ring has a unique ID and an associated IP address, which are as follows:
1. RING ID 0: Node ID 1023480842, local node ID on `node1`, IP address `10.20.1.61` is active with no faults.
2. RING ID 1: Node ID 1040258058, node located at `node2.acme.com`, IP address `172.16.100.61` is also active with no faults.
To verify the quorum status of Corosync, the command `corosync-quorumtool -l` was executed, showing that both nodes (node1 and node2) are members with one vote each:
Node ID 1023480842 on `node1.acme.com` has 1 vote.
Node ID 1040258058 on `node2.acme.com` also has 1 vote.
Next, the configuration for DRBD is checked and updated to specify network addresses and disk partitions that will be managed by DRBD. The configuration file `/etc/drbd.d/clusterData.res` is edited with details about the nodes and their respective IP addresses:
`NODENAME1A` corresponds to `node1`.
`NODENAME2A` corresponds to `node2`.
`/dev/drbd0` is the device specified for managing the disk partition.
Network communication through port 7789 (`NODE1IP1:7789` and `NODE2IP1:7789`) is allowed, allowing two primaries if necessary.
Before initializing DRBD partitions, it's crucial to ensure that the specified disk partitions do not contain any valid data, as the initialization commands will erase all data without prior backup. The configuration file for DRBD looks like this:
```bash
resource clusterData {
meta-disk internal;
device /dev/drbd0;
syncer {
verify-alg sha1;
}
net {
allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
after-sb-2pri disconnect;
}
on NODENAME1A {
disk PARTITION;
address NODE1IP1:7789;
}
on NODENAME2A {
disk PARTITION;
address NODE2IP1:7789;
}
}
```
Finally, the initialization of DRBD partitions should be done on `node1` using the following commands:
```bash
drbdadm create-md clusterData
modprobe drbd
drbdadm up clusterData
```
These steps ensure that the distributed replication block device is properly configured and initialized for use as a shared cluster filesystem.
The provided text describes the process of setting up a DRBD shared disk, configuring Pacemaker for a cluster, and integrating an ArcSight SmartConnector. Here's a summary of the steps involved in this process:
1. **Setup DRBD Shared Disk**:
Command to check status: `dm up clusterData`
View DRBD details: `cat /proc/drbd`
Commands on node2 for creating metadata, loading module, and bringing up the disk:
```bash
ssh node2 -- drbdadm --force create-md clusterData
ssh node2 -- modprobe drbd
ssh node2 -- drbdadm up clusterData
drbdadm -- --overwrite-data-of-peer primary clusterData
```
The DRBD disk should start synchronizing once the above steps are completed. You can check its real-time status in `/proc/drbd`.
2. **Configure Pacemaker**:
Refer to (https://www.clusterlabs.org) for detailed information on Pacemaker, which is a cluster resource manager that includes health checks and policy engine.
Resources are grouped into Base Group (DRBD, file system, IP) and Connector Group in the Pacemaker configuration.
Setup complex configurations such as node limitations, ordering, and dependencies should be done using the scripts available at `/root/crm/crm`.
Check current cluster status with `crm_mon` command.
3. **Configure ArcSight SmartConnectors**:
After setting up base cluster resources, run a quickstart script that will guide you through configuring the syslog SmartConnector within the system.
The script will prompt for settings and wait for completion after displaying expected values.
4. **Configure Remaining Pacemaker Services**:
Once the connector is set up, add it to the cluster primitives and configure health monitoring in Pacemaker.
At this point, the cluster should be operational for syslog events directed at the VIP.
5. **Operating the Cluster**:
Starting and stopping connectors can be managed using `resource stop` or `start` commands as needed.
This process provides a comprehensive guide to setting up a DRBD shared disk with Pacemaker, integrating an ArcSight SmartConnector, and configuring cluster resources effectively.
The provided text outlines various commands and procedures related to managing a Linux-based cluster using Pacemaker and Corosync for startup, shutdown, resource management, and troubleshooting. Key points include:
1. **Cluster Management Commands:**
Commands to manually stop and start the cluster: `pcs resource stop` and `pcs resource start` for specific resources like `SyslogUdp1`.
Manual shutdown of primary and secondary nodes: Use `shutdown -h now` on both primary (active) and secondary (passive) nodes.
Automatic startup sequence includes starting corosync and pacemaker components, followed by cluster resources selecting a node to start.
2. **Moving Connectors to Partner Node:**
Utilize `pcs cluster standby` to put a node into standby mode, allowing the cluster to manage its resources effectively without user intervention once stable. Use `pcs cluster unstandby` to return control to the policy engine.
3. **Resolving DRBD Split-brain Situations:**
In case of dual primary ownership detected by DRBD, manual steps are required to resolve conflicts: stop and detach from both nodes (`drbdadm down`), attach and configure on one node, reconnect (`drbdadm connect`). Repeat on the secondary node. Finally, restart the cluster services.
4. **SyslogUdp1 Connector Monitoring:**
To test connector functionality and monitor the cluster, update `/etc/rsyslog.conf` to include configurations that trigger syslog events. Verify operation with `service pacemaker start` after necessary modifications.
This summary provides a basic understanding of how to manage and troubleshoot a Linux cluster using Pacemaker and Corosync based on various scenarios described in the text. The provided text outlines a setup for configuring an rsyslog service to work with ArcSight SmartConnectors in a high-availability (HA) setup within a Linux environment, particularly focusing on using Pacemaker for cluster management and ensuring the HA of event collection without relying on external hardware load-balancers. Key points include: 1. Configuration settings for rsyslog are provided, including specifying where to place spool files, setting up action queues, and configuring remote syslog server settings. 2. The command to restart the rsyslog daemon is given as "service rsyslog restart". 3. Instructions for monitoring connector activity in the cluster involve checking logs on the primary cluster node and looking for indications of active Event Thread (ET) and Health Thread (HT). 4. The document explains that this configuration is tailored for environments with two 1U servers similar to HP ArcSight C5500 Connector Appliances, without modifying actual appliances as it could void support agreements. 5. Clarifies that while the text does not explicitly cluster two Connector Appliances, it sets up a high-availability syslog UDP daemon within those configurations. To answer your questions and summarize the provided information, let's go through each question one by one with their corresponding answers: **Q3: Do I need any SAN or NAS disk to make the cluster work?** *A3:* No, you don't need SAN or NAS disks for the initial configuration. The setup requires local disk partitions on each node dedicated to a shared cluster file system. While theoretically SAN disks can be used as they would look like local disk partitions, the expectation is for cost effectiveness with general purpose servers without external components. **Q4: How long does this take to get running?** *A4:* Without including time to load CentOS 6.4 OS, it takes about 15 minutes to have the cluster up and running using a quick-start script and pre-configured connectors. However, setting everything from scratch including loading the OS, configuring SmartConnectors, and the cluster could take no more than four hours. **Q5: Can I use bonded Ethernet interfaces?** *A5:* Yes, you can use bonded Ethernet interfaces. Ensure that network interfaces are set up statically (e.g., eth0 + eth1 = bond0 and bond0 has a static address defined), as the Cluster resource script IPaddr2 should correctly detect the interface name if it’s configured this way. **Q6: If the cluster goes down, do the connectors continue running?** *A6:* If the cluster was shut down gracefully, the connectors would stop since the VIP and shared file system would be stopped along with the nodes. With only two nodes, split-brain is a risk, so it's unlikely both nodes would fail simultaneously. Future configurations could include additional nodes or STONITH devices to increase resilience. **Q7: Does each connector need its own VIP?** *A7:* Each connector does not necessarily need its own VIP unless they are using the same TCP or UDP ports. The initial configuration uses a single VIP. **Q8: How long does the cluster take to move a connector to the partner node?** *A8:* This question isn't fully answered in the provided text, but based on the previous answers and the context of other questions, it can be inferred that if the cluster is functioning properly, moving a connector to another node should occur smoothly as part of its normal operation. The specifics regarding time taken for this process would depend on various factors including network speed, configuration settings, and the size and complexity of the data being moved. For more detailed information or specific troubleshooting steps, it's recommended to refer back to the original text or consult with technical documentation provided by the vendor or developers of the software in question. The VIP (Virtual IP) move in a cluster typically takes less than three seconds, but the connector shutdown and startup can take up to 50 seconds under certain conditions, such as if the cluster has issues stopping the connector on the source node. In extreme cases like a cluster node failure where both management and production interfaces are offline, the transition time is usually several seconds at most, definitely sub-minute. The main weaknesses of the cluster are: 1) Lack of STONITH (Shoot The Other Node in the Head) capability, which means it cannot automatically recover from split-brain scenarios without manual intervention. 2) Issues with DRBD (Distributed Replicated Block Device) configuration and auto-recovery from split-brain, where there's a risk of corrupting partitions if not handled correctly. Monitoring the cluster is possible to some extent as there are command line cluster status commands available that can reveal the health of the cluster and its connectors. However, there isn't an SNMP MIB (Management Information Base) for monitoring. Online forums on clusterlabs.org can be helpful but direct support from HP Enterprise Security Products is not available. When using the IPsrcaddr primitive in a cluster configuration, it may fail due to auto-configuration of IP addresses set by 169.254.0.0/16 dev eth0 and eth1 routes. This can be resolved by disabling auto-configuration with NOZEROCONF=yes in /etc/sysconfig/network settings. Adding more connectors involves following the instructions provided in the connector section of the quickstart script, typically requiring installation on the currently active cluster node. This document outlines steps for setting up a connector in a cluster environment, ensuring it runs as a service without auto-starting, and managing remote connections. It also addresses specific issues users might encounter during setup or operation. Here's a summary of key points from the text: 1. **Setup Connector**: The connector should be set up on each node with an equivalent system using the same file system path (e.g., /cluster/connectors/smartconnectorname). 2. **Service Setup**: Configure the connector to run as a service but not to automatically start on system boot. 3. **Copy Script**: Copy the /etc/init.d startup script from one node to another if needed. 4. **Run and Manage**: Ensure the connector starts and runs correctly using /etc/init.d commands, or stop it when necessary. 5. **Remote Management Port**: Set up a unique remote management port in the agent.properties file. 6. **Add to Cluster**: Add the connector to the cluster and the ConnectorGroup as needed. 7. **Update Control Scripts**: Update any control scripts used to manage connectors within the cluster. Regarding configuration of Logger and Manager destinations, it is noted that preconfigured settings will not work due to unique certificates required for management. Reconfiguration from ARCSIGHT_HOME/current/bin is recommended. Errors during quickstart script execution such as "ClusterStatus-prefer-node1: referenced node xyz does not exist" are common but can be ignored, per release notes. These relate to crm system messages and do not indicate a failed installation. Lastly, issues specific to DRBD on RHEL 6.2 and the requirement for a dedicated web server are mentioned, with future versions expected to address these limitations. The current version requires separate Apache servers for cluster status display. Additionally, crm_mon might exit unexpectedly under certain configurations, though this issue is not detailed further in the provided text. The text provided appears to be a log from a Cluster Information Management (CIM) or High Availability (HA) clustering system setup process, likely using the Pacemaker or similar tools for managing resources across multiple nodes. Here's a summary and breakdown of the key points mentioned in the excerpt: 1. **Cluster Setup Warnings**: The script issued several warnings about potential modifications to system settings including disabling security features like SELinux and IPtables. It also highlighted that any data on the specified disk partition would be overwritten without backup, which could lead to data loss if not properly prepared beforehand. 2. **Installation Specifics**: The installation process is intended for the first node only; subsequent nodes should not execute setup commands unless explicitly instructed. This log does not provide details about successful completion of the cluster setup but focuses on preparatory steps and warnings regarding potential risks. 3. **CRM Upgrade Errors**: There was a mention of known issues with 'upgrade' errors related to the crm_mon command, which occurs after certain actions that modify the Cluster Information Base (CIB). The suggested workaround is to simply restart the crm_mon command. This indicates potential reliability or configuration issues within the cluster management tools being used. 4. **DRBD Synchronization Requirement for Failover**: There's a specific note about the necessity of fully synchronized DRBD partitions for proper cluster failover, which means waiting until the initial sync is complete before testing failover scenarios. This highlights an operational aspect where data consistency across nodes must be maintained to ensure fault tolerance and high availability features are functioning correctly. 5. **Further Reading**: The text suggests that more detailed information can be found in a white paper published by ClusterLabs.org and related resources at linux-ha.org, indicating the need for further technical documentation or community support for understanding and troubleshooting issues specific to such setups. Overall, this log provides insights into preparatory steps, warnings about potential risks and system modifications, and notes on known issues within a cluster setup environment using advanced HA tools, with guidance on where to seek additional information and assistance. The document outlines a process for setting up a cluster, providing options to proceed or skip steps as guided. At the start of each step, there are three options: Proceed (p), Skip (s), or Quit (q). This is illustrated in the prompts like "Proceed/Skip/Quit?
/s/q:" which appear at various points throughout the document.
**Step 1: Setup Cluster Parameters**
Describes default values for cluster configuration, encouraging verification and potential changes.
Prompts to set specific parameters such as node names, IP addresses, network details, domain, and filesystem directory.
Example prompts include "Set value for clusternode1 :" which guides the user through setting or confirming each parameter.
**Step 2: Setting up Root SSH Keys**
States that this step generates and exchanges cluster node root ssh keys.
Recommends skipping if mutual public key authentication is already set up.
Mandates installation of ssh clients on both nodes (ca1 and ca2).
Provides a prompt "Proceed/Skip/Quit? /s/q:" which asks for user input to decide the next action.
The process of generating an RSA key pair for SSH communication involves several steps, including specifying the location to save the keys and entering a passphrase. In this case, the commands were run on two different servers, ca1 and ca2, via SSH from another machine (assumed to be identified as 'root@ca2').
**Key Generation Process:**
When prompted for the filename in which to save the key, both servers initially defaulted to '/root/.ssh/id_rsa' but did not specify a public key location.
The passphrase prompts were followed, with an empty passphrase being set due to user input asking for no passphrase (for simplicity or security reasons).
After entering these details, the keys were successfully saved in '.ssh' directories under '/root/.ssh/id_rsa' and '/root/.ssh/id_rsa.pub'.
**Key Fingerprints:**
The fingerprint of the key on ca1 was 'c4:6a:8d:79:a4:fe:ac:05:a9:c4:19:ba:1f:d1:57:1b root@ca1'.
On ca2, after generating a new key pair, the fingerprint was 'e7:e7:5d:03:d6:c4:28:c0:bd:19:33:0e:3d:f6:4d:b2 root@ca2'.
**Authorizing Keys:**
The public keys from both servers were exchanged by entering the respective server's root password, confirming the authenticity of the host using 'yes/no' prompts.
The key files ('id_rsa.pub') were sent to each other via SSH, and upon successful authorization, their contents were appended to the authorized_keys file on the receiving end.
**Building Common Hosts File:**
A final step involves building a common '/etc/hosts' file across both nodes, which was initiated with user input asking whether to proceed ('Proceed/Skip/Quit? /s/q:'). This setup is crucial for consistent network naming and addressing in multi-node environments.
This sequence of operations outlines the comprehensive configuration process required to establish secure SSH connections between multiple servers using RSA key pairs, ensuring secure authentication without reusing passwords. The text provided appears to be a log or output from a system administration task involving the configuration of network and security settings, as well as installation of cluster-related packages. Here's a summary of the key points mentioned in the text: 1. **Distributing Host Files**: There is an operation where host files are being distributed between two hosts named ca1 and ca2. The process involves copying /etc/hosts from one host to another when prompted for the root password. During this, SSH connection authenticity with ca2 needs to be established due to not having SSH keys set up yet. RSA key fingerprint is provided to verify the host's identity: 'a7:7a:b5:a6:13:51:cf:59:5e:27:30:01:df:1b:d2:a5'. The user needs to confirm with "yes" to continue connecting. 2. **Network/Security Service Configuration**: In this step, network configurations are updated and certain security services (SELinux and IPtables) are disabled on both ca1 and ca2 hosts. Network interfaces eth0 and eth1 were shut down and then brought back up, and iptables rules were flushed and unloaded to disable them. SELinux was also temporarily disabled for the process. 3. **Install Cluster Related Packages**: On both ca1 and ca2, cluster-related packages like corosync, pacemaker, pcs, DRBD, and others are being installed from a repository hosted at elrepo.org. Installation steps vary per host due to network constraints (HTTP retrieval). The text does not provide complete details about all the commands or operations performed during these tasks; it serves as a log of progress with some informational messages and prompts for user interaction. The provided text is a summary of an RPM (Redhat Package Manager) installation process on a Linux system, specifically CentOS 6 with the elrepo repository. Here's a breakdown of what it indicates: 1. **File Description**: It mentions `se-6-5.el6.elrepo.noarch.rpm`, which is an RPM package file for a software named "se" in version 6.5, compatible with EL (Enterprise Linux) release 6, from the elrepo repository. The suffix `.noarch` indicates that it's an architecture-independent package. 2. **Warning**: During the installation process, there was a warning about the header verification using DSA/SHA1 signature and key ID baadae52 which is not recognized or available locally (NOKEY). 3. **Installation Process**: The system was preparing for an install with a message indicating progress towards completion: "Preparing... ########################################### <100%>
". Afterward, the package "elrepo-release" was installed successfully.
4. **RPM Execution**: This process involved running `rpm -Uvh se-6-5.el6.elrepo.noarch.rpm`, where `-U` stands for upgrade (if already installed) or install if not present, and `-h` shows the hash marks (`#`) to indicate progress during the installation.
5. **RPM Execution Output**: The output includes details about what plugins are loaded, such as "Loaded plugins: fastestmirror", which indicates that the system is using a plugin for optimizing mirror selection based on speed. It also mentions determining the fastest mirrors available, with specific URLs listed for base, elrepo, extras, and updates repositories.
6. **Dependency Resolution**: The script resolved dependencies by running a transaction check to ensure all necessary components were present before proceeding with installation. This step is crucial as it ensures that none of the dependent packages are missing when installing or upgrading an RPM package.
7. **Installation Summary**: After resolving dependencies, the summary indicated that 61 new packages and 3 upgraded packages were installed. The total download size was about 57 MB. A list of installed packages is provided at the end, showing details like version numbers and architecture (e.g., `x86_64`).
This log provides detailed information on how an RPM package is handled during installation in a Linux environment, including dependency resolution and repository usage.
The text provided appears to be related to the installation and configuration of software components, particularly focusing on NFS utilities, Samba, and other system packages. Here's a summarized breakdown of the key points mentioned in the text:
1. **Software Installation**: A list of various RPM (Red-Hat Package Manager) packages are being installed or updated as part of the installation process. These include `nfs-utils-lib`, `nss-softokn-freebl`, `ntpdate`, `pacemaker-cli`, `pacemaker-cluster-libs`, `pacemaker-libs`, `perl`, `pkgconfig`, `quota`, and `resource-agents`.
2. **Dependency Resolution**: During the installation process, there is a resolution of dependencies where `glibc` and other related libraries are updated or resolved as part of installing higher versions of these packages.
3. **Specific Versions and Packages**: The specific versions for each package being installed or updated are detailed in the format: `. 0:-.el`. For example, `nss-softokn-freebl.i686 0:3.14.3-3.el6_4` indicates a specific version of a package for i686 architecture.
4. **Complete Installation**: After resolving dependencies and installing all specified packages, the text confirms that the installation process is complete.
5. **System Configuration**: The configuration step involves setting up an NTP client (Network Time Protocol) to synchronize time across multiple systems labeled as `ca1` and `ca2`. This setup includes enabling and starting the ntpd service on both systems.
6. **NTP Setup Confirmation**: After enabling and starting the ntpd service, a prompt appears asking whether to proceed or skip this step. The response 'p' stands for "proceed".
In summary, the text is detailing an installation process in a Linux environment where specific software components are being updated or installed, with dependencies resolved automatically. Additionally, there's a focus on configuring network time synchronization across multiple systems using NTP.
In this process, the task is to configure and set up a corosync cluster on two nodes. The steps involve creating and distributing a `corosync.conf` file, along with an authentication key (`authkey`) and specific service configurations (`service.d/pcmk`). After setting up these files on both nodes, the next step is to start and test the corosync daemon on each node.
During testing, the status of the rings is checked to ensure that they are active with no faults. The local node ID and ring status for both nodes are printed out as part of this process. If everything is set up correctly, the next step would be to re-start corosync and re-run the tests; however, in this case, the user chose to skip these steps directly after printing the initial test results.
Finally, if proceeding with re-testing was desired, the corosync services on both nodes would need to be stopped gracefully before restarting them for further testing. If not, the process could end as per the user's input.
The summary of the provided text is as follows:
The text describes a process involving DRBD (Distributed Replicated Block Device) configuration and setup. It starts with confirming successful tests, offering options to either proceed or quit based on test results. If tests are successful, one must select "Proceed". Otherwise, they should choose "Quit" and rectify the issue before retrying.
Step 9 involves building a DRBD configuration file named 'clusterData.res' which is distributed to both nodes. This step includes backing up an existing file if present, copying the new file to each node, and notifying that the process completes successfully with details about file transfer speed and completion percentage.
Step 10 pertains to setting up DRBD partitions on both nodes. It warns of potential data loss on '/dev/sda3' due to configuration changes and advises against running this step if it has been executed previously without proper knowledge, as it might lead to failure requiring manual recovery. The command "zeroing partition header space" is mentioned, followed by writing DRBD metadata to the partition on 'ca1', with a system message thanking the user for participating in a usage survey and providing server response details including version information and build date.
Lastly, Step 10 includes bringing up the partition on 'ca1' which displays current status of DRBD setup via '/proc/drbd'. This step is part of initializing activity log and metadata without bitmap initialization, resulting in a new drbd meta data block being successfully created upon completion with details about success.
The provided summary outlines a series of actions taken with DRBD (Distributed Replicated Block Device) for setting up a partition on a storage device named "ca2". Here's a breakdown of the steps and events recorded in the summary:
1. **DRBD Metadata Initialization**:
A new DRBD metadata block is created on the partition located on "ca2". The process starts with initializing an empty bitmap, which is then used to write the meta data. This step involves initializing the activity log and completing the initialization of the DRBD meta data block.
2. **Partition Activation**:
After creating the metadata block, the system attempts to bring up the partition on "ca2". This step includes checking the status through `/proc/drbd` which shows a connection in a write-locked state with secondary role and inconsistent data status.
3. **Forcing Node Role**:
To proceed with the setup, it is necessary for one node (ca1) to take on the primary role manually. The synchronization process between nodes begins post this step.
4. **Partition Synchronization**:
A partition sync operation is in progress as both nodes attempt to synchronize their data. Users are advised to check the progress by issuing the command `cat /proc/drbd`.
5. **Filesystem Creation**:
Once synchronization is complete, filesystem creation on the DRBD device starts using the `mke2fs` tool. This process involves formatting the disk with a Linux filesystem (ext3 or ext4 are typical), setting parameters like block size and inode count based on available space. The filesystem label, number of inodes, blocks reserved for superuser, and other properties are configured during this step.
6. **Mount Point Creation**:
On both nodes, mount points for the new filesystem (e.g., `/cfs`) are created to facilitate access.
7. **Webserver Configuration**:
Document roots and status webservers are set up under the `/cfs` directory on each node. This includes updating Apache HTTP server configuration files (`httpd.conf`) to reflect the new filesystem location for serving content.
8. **Finalizing Configuration**:
The final step involves backing up the original `httpd.conf` file, copying it to both nodes' configurations, and confirming the update is successful.
This summary provides a concise overview of how DRBD was used to set up a distributed filesystem on two nodes (ca1 and ca2), including the configuration of metadata, synchronization procedures, and setup tasks such as creating mount points and configuring web servers.
The provided text is a summary of a setup process for setting up a cluster, specifically focusing on configuring resources such as partition, file system (FS), IP address, and status using tools like Corosync and Pacemaker. Here's a detailed breakdown of what happened during this process:
1. **Setup Base Cluster**:
The script built and started the base cluster by setting up partitions, file systems, IP addresses, and status on both nodes.
It installed an ArcSight SmartConnector cluster resource agent to each node.
Backed up existing configurations for corosync and pacemaker.
Copied necessary configuration files (corosync.conf) to the appropriate directories.
Restarted Corosync and Pacemaker daemons to ensure they were running properly.
2. **Configure Cluster Resources**:
The script set up cluster resource primitives and dependencies, including configuring DRBD for the cluster.
It added a `ClusterDataClone` (kind: Mandatory) with options like first-action=promote then-action=start to manage file system replication.
Added `ClusterFS ClusterIP` and `ClusterIP ClusterSrcIP` as mandatory resources, both configured to start automatically when needed.
The CIB (cluster information base) was updated after each configuration step to reflect the changes made by Corosync and Pacemaker.
In summary, this setup script orchestrated a comprehensive process of configuring and initializing a cluster environment with key components like DRBD for file system replication, IP addressing, and status management using advanced clustering tools. The text provided outlines a sequence of steps in setting up a syslog SmartConnector for a cluster, specifically mentioning that this step pauses the cluster installation to facilitate the addition of a syslog connector controlled by the cluster. It emphasizes the prerequisite that base cluster resources (ClusterData, ClusterFS, and ClusterIP) must be operational before proceeding with this setup. Additionally, it provides specific details about the values needed for installing the syslog SmartConnector, such as the install folder, device location, port to listen on, IP address, internal/display service names, whether to start the service automatically, and the destination host name/IP along with the required receiver name. The steps include starting the SmartConnector installation via a Linux script and running the setup using `runagentsetup.sh` within the connector's bin directory. The instructions also highlight warnings about specific values that must be used during the installation process to ensure proper functionality of the syslog SmartConnector, with clear cautions against creating links or specifying IP addresses incorrectly. To set up a syslog SmartConnector cluster in your environment, follow these steps: 1. **Start SmartConnector**: Open a new window and run the command to start SmartConnector by executing `/etc/init.d/arc_syslog_udp_1 start`. This will initiate the connector startup process for remote management properties. 2. **Monitor Connector Startup**: Look for connector startup events on your destination IP address 10.20.1.55:443 with the SmartMessage Receiver. You can also monitor the connector wrapper log by running `tail -f /cfs/connectors/syslog-udp-1/current/logs/agent.out.wrapper.log`. 3. **Stop the Connector**: To stop the connector, run `/etc/init.d/arc_syslog_udp_1 stop`. 4. **Continue to the Next Step**: Press to continue to the next section where you will add remote management properties to the agent.properties file and copy the init.d script to a new location. 5. **Setup SmartConnector Cluster Resources**: This step involves setting up connector cluster resource primitives and dependencies. Follow the prompts: Proceed/Skip/Quit?
/s/q, where you should select "Proceed" by pressing 'p'.
6. **Build syslog SmartConnector Cluster Primitives and Dependencies**: The system will update 34CIB with new information about the SyslogUdp1 cluster resource (kind: Mandatory) with actions set to start both first-action and then-action.
7. **Setup Complete**: Once complete, you should have a syslog connector configured and running under cluster control. You may see base events from cluster nodes in the Logger destination. The rsyslog daemon on all cluster nodes is configured to send events to the Syslog SmartConnector on 10.20.1.195:514/udp.
8. **Cluster Status**: Check the current status via HTTP at http://10.20.1.195/status.html, or use command line tools like `pcs status` or `crm_mon`.
9. **Force Migration (Optional)**: To force a migration to another node (e.g., ca2), put the current node (ca1) into standby mode with `pcs cluster standby ca1`, wait for everything to move, and then give control back to the cluster with `pcs cluster unstandby ca1`.
This process should provide you with a fully functional syslog SmartConnector cluster ready for management and monitoring.
This passage is about managing resources in a cluster, where the system detects a resource failure and automatically moves the affected resources to another node (partner node) for continued operation. Additionally, it provides guidance on setting up additional connectors by following specific commands during the SmartConnector setup step. For more detailed information on how this works within the context of a cluster or creating one from scratch, refer to the provided background reading materials. The passage also mentions that the process is completed at a specific time: Mon Sep 16 08:42:29 CDT 2013.
