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
