Sorry but it told you, remove <cman expected_votes="5"> and reboot the cluster
Let the cluster calculate the expected votes
2012/8/1 GouNiNi <gounini.geekarea@xxxxxxxxx>
I do this test one more time and I got same result with more precisions:
When I shutdown network on 2 nodes including the master, master stay alive while the 2 online nodes are fencing the offline non-master node. The cluster goes Inquorate after.
When fenced node came back, he joins cluster and cluster becomes quorate. New master is chose and the old master is fenced.
