Andrew, We would normally do a rolling implementation of a new release of heartbeat / pacemaker where possible. We run with two node clusters in a virtualized environment.
1. Shutdown Backup node 2. Update Heartbeat and Pacemaker packages on the backup node 3. Restart the backup node 4. Put the primary node in standby - to relocated the resources to the updated backup node 5. Shutdown the Primary Node 6. Install the updated Heartbeat / Pacemaker packages on the primary node 7. Restart the primary node 8. Take the primary node out of standby - it is now the backup node for the cluster This approach only requires a single application outage to the end users Thanks...

Me again, I'd like to get a sense of how people upgrade their clusters... * rolling upgrade (node-by-node) * big-bang (all nodes at once with all resources stopped) * detach and reattach (all nodes at once with resources still running) * other? I'm interested to know how popular the various methods are.
