Also, make sure that your host files are setup properly. Otherwise, if left
to the default redhat config, your cluster nodes are binding to localhost and
will never see eachother. I know it's very basic, but it's easy to overlook.

After you created the initial cluster configuration, did you scp (or
otherwise transfer) the /etc/cluster/cluster.conf file to all machines?

Are there any iptables firewalls that are prohibiting cluster members from
talking to one another?

What is the output of "cman_tool status"
