You may be hitting this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=249705. There's an updated
rpm attached to https://bugzilla.redhat.com/show_bug.cgi?id=253843 that
you may want to give a shot. Alternately, you could use conga.

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?

Make sure you bumped the cluster config version number, then run
'ccs_tool update /etc/cluster/cluster.conf' on one node with the
updated cluster.conf file. That will propagate the updated
configuration to the rest of the running nodes and update the
configuration version number.
