How to Remove an HA Heartbeat Cluster on SLES 10

This document (3964086) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 10
 

Situation

High Availability Release 2 and Heartbeat

There are times that you may want to completely start over with the high availability (HA) configuration. The process described assumes you are using the default cluster information base (CIB) database. All resources will be lost, but the cluster configuration files themselves are not, and can be modified.

Resolution

Do the following on all nodes in the HA cluster.
1. rcheartbeat stop
2. rm $(find /var/lib/heartbeat -type f)
3. rm /var/lib/heartbeat/fifo

At this point you should check the /etc/ha.d/ha.cf file on all nodes for a valid cluster configuration. Then run 'rcheartbeat start' on all nodes to recreate the cluster and start heartbeat services.

A new UUID will be given to each node. This is why it's important to complete these steps on all nodes to avoid a duplicate node scenario.
