Are you sure, that your qdisk-configuration is ok and it's working properly? Just based on maths, it seems that you have only 4 votes up in your cluster and it goes down if it loses one vote... So is cman_tool really showing exp.votes=7? And qdisk brings it's votes ok? -hjp ________________________________________ From: linux-cluster-bounces@xxxxxxxxxx [linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Moralejo, Alfredo [alfredo.moralejo@xxxxxxxxx] Sent: Tuesday, August 18, 2009 4:26 PM To: linux clustering Subject: RE: Cluster behavior Could you send logs in messages file including the part where the cluster dissolved messages is logged?

Node A - Vote 1 Node B - Vote 1 Node C - Votes 2 Qdisk - Votes 3 Altogether the cluster has 7 votes. The required min quorum to run the cluster would be in this case 4. Now if I poweroff node 1, I can see Quorum Dissolved in the terminals of Node 2 and Node3 . This cluster has xen virtual machines. Whats wrong and how to do debug the problem?
