Special Note for Version 2 Users

The CRM is now maintained as an independent project called Pacemaker and now has many new features including support for the OpenAIS cluster stack.

Heartbeat 2.1.4 was the last release to contain the CRM or "Version 2 Resource Manager" and since then all development and maintenance is performed as part of the Pacemaker project and all CRM code has been removed from Heartbeat.

For more details on Pacemaker, including latest versions, installation details and documentation, please visit http://clusterlabs.org.

Heartbeat Version 2

The Heartbeat program has been around for a while. It has a great many strengths, and yet there were a few weaknesses in version 1 that needed to be addressed:

• limitation on two nodes for cluster size

• inability to monitor resources for their correct operation

• minimal ability to express dependency information

The version 2 series of Heartbeat removes these limitations while preserving as many of version 1's strengths as possible.

In the new design, the main components are as follows:

• HeartbeatProgram

• LocalResourceManager

• ClusterResourceManager

• ClusterInformationBase

• StonithDaemon

For detailed information on version 2, please see the following pages:
