[Pacemaker] won't join cluster

[James Harper]

I just tried to join two machines to a cluster that were previously members of another cluster. One worked fine, but the other seems to have some problems. "crm status" says everything is offline, but the other nodes all see it as online and resources actually seem to start. It seems to say this a lot:

ERROR: cib_perform_op: Discarding update with feature set '3.0.6' greater than our own '3.0.5'

But there are other errors too (I'd have to sanitise the logs but can post if it would help)

Have I got a mismatched version or something?

Failing that, how do I clean out all the cluster configuration (cib etc) so it's like it's been just installed and can start from scratch?

Everything is 1.1.7.

Thanks

James
