[Linux-cluster] Quorum disk

[Hunt, Gary]

Having an issue with my 2 node cluster.  Think it is related to the quorum disk.

2 node RHEL 5.3 cluster with quorum disk.  Virtual servers running on each node.

Whenever node1 takes over the master role in qdisk it looses quorum and restarts all the virtual servers.  It does regain quorum a few seconds later.  If node1 is already the master and I fail node2; things work as expected.  Node2 doesn't seem to have a problem taking over master role.

Whenever node1 needs to take over master role the cluster looses quorum.  Here is my cluster.conf.  Any suggestions on what may be causing this?
