Don't use a CFS on dom-0, use a CFS within driver domains (guests). If
dom-0 is a member, you run a very high chance of it rebooting
unexpectedly due to heartbeats. A reboot on dom-0 can take 30+ guests
(and their file systems) for a spin.

I *highly* recommend ocfs2 over GFS for simplicty, reliability and ease
of use, its only a few keystrokes away on any 2.6 + system. The
configuration is much, much easier as well.

I  don't much care for the RH cluster suite. But, just one Xen user's
opinion :) I should also note I'm a Debian(ish) user. Of the 5 size-able
clusters I have on line, 4 are using ocfs2 and I'm about to convert the
fifth.

GFS had an inode vulnerability a few months back that didn't get as much
mention as it should (that I saw), you may want to check to be sure
that's been fixed. It had to do with a user creating a mass amount of
randomly named files just a few bytes long, then deleting them. 

Best,
--Tim
