I did some tests on 4 nodes cluster with quorum device and I find a bad situation with one test, so I need your knowledges to correct my configuration.

4 nodes, all vote for 1
quorum device vote for 1 (to hold services with minimum 2 nodes up)
cman expected votes 5

I shut down network on 2 nodes, one of them is master.

Fencing of one node (the master)... Quorum device Offline, Quorum disolved ! Services stopped.
Fenced node reboot, cluster is quorate, 2nd offline node is fenced. Services restart.
2nd node offline reboot.

My cluster is not quorate for 8 min (very long hardware boot :-) and my services were offline.

Do you know how to prevent this situation?


Please tell us the name and version of the cluster software you are using, Please also share your configuration file(s).
