Hello list,
Using SUSE SLES 11 SP2.
I have 4 servers in a cluster running cLVM + OCFS2.
If I tried to shutdown the one that is the DC using openais stop, strange
things happen resulting in a really messed up cluster.
One one occasion, another server decided he was the DC and the other 2 still
thought the original DC was "online" and still it.
Often it results in fencing and lots of reboots.
If I tried to put the DC into standby mode, I get this
cpzea01a0017:~ # crm node standby cpzea01a0017
Error setting standby=on (section=nodes, set=<null>): Remote node did not
respond
Error performing operation: Remote node did not respond
Is there some special way to take it down?
