Some silly questions:

Q1. is it a two node cluster? if so, have you configured is as such using two_nodes
---- http://sources.redhat.com/cluster/wiki/FAQ/CMAN says

How can I define a two-node cluster if a majority is needed to reach quorum?

We had to allow two-node clusters, so we made a special exception to the quorum rules. There is a special setting "two_node" in the /etc/cluster.conf file that looks like this:

<cman expected_votes="1" two_node="1"/>

This will allow one node to be considered enough to establish a quorum. Note that if you configure a quorum disk/partition, you don't want two_node="1". 


Q2. Are the cluster member nodes able to resolve each others names? (either through DNS or /etc/hosts file)
Q3. have you used cman_tool join command to join the nodes to the cluster?
