Definitely. As others have noted it is intended to be run as part of a
OCFS2 is an alternative that is happy to list just as a clustered
filesystem. I had stability problems under Lenny (2 node cluster)
Have you considered distributed filesystems? They are a different class
from either clustered filesystems (GFS,GFS2,OCFS2) and network filesystems
(NFS and lots of others). One popular distributed filesystem is Lustre.

A clustered filesystem prevents any one server from being the single point
of failure (although the SAN remains a SPoF). Unfortunately I've seen
clustered filesystems fail to recover properly from server outages more
often that I would like - generally in a 2-node arrangement.
