[Linux-cluster] want to use GFS2

Just two cents, I believe Red Hat does support GFS2 on single server using lock_nolock, because we do SAN "snaps" of actively clustered GFS2 volumes (simple flatfiles, no databases) and present the snap luns to a media agent server to backup the data oob.  RHN was okay with that configuration and we have been running it this way on GFS and GFS2 for 5-years without issue.

Well, technically you can use GFS2 without a cluster setup.
I believe Red Hat doesn't support it, and the storage can't be mounted by more than a single computer (with "lock_nolock"
locking protocol), but it can be done.
