Yes. After trying the above rpm, system-config-cluster works much much better. Thank you very much Ryan.

Once I did that and ran the 'service cman start', I got an error saying that the local node name is not present in the cluster.conf. When I checked the conf file again, the node that I added disappeared after I ran cman start?
