I've found that OCFS2 is a very decent clustered filesystem for smallish
environments (4 or 8). We had trouble with larger clusters.

This is probably the better question. Using a clustered filesystem can
be handy for redundancy, and you could use OCFS2 or DRDB for that, but
don't expect to be able to run multiple PG servers concurrently from the
same set of data files.
Thanks!
