Heartbeat Version 2

The Heartbeat[1] 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 node[2]s for cluster[3] size

• inability to monitor resource[4]s for their correct operation

• minimal ability to express dependency information

The version 2 series of Heartbeat[1] 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[5]

• LocalResourceManager[6]

• ClusterResourceManager[7]

• ClusterInformationBase[8]

• StonithDaemon[9]
