For gfs2 to be used it is good to use with the cluster but not necessarily check the release notes but if clvmd is used then cluster is necessary .
Cman is no more a kernel module but cman is the primary service which must be running to set up the cluster.

Can you be a bit more specific with your request ? Are asking how to you use clvm in RHCS ? Whether you are using san, or any other method of external storage, you require to have the lvm2-cluster rpms in order to be able to use clvm with RHCS.
