[Linux-cluster] Cluster behavior

[Harri.Paivaniemi at tieto.com]

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?

I have a 3 nodes cluster.

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?

Thanks
Paras.
