Actually, on RHEL, the *only* filesystems that upstream *officially*
supports are ext2/3 and GFS.  Not XFS, nor reiser, nor JFS.  Nada...

Well, maybe FAT for USB-attached storage... ;)

But if you're using CentOS, it's entirely up to you... If I were in
RHEL-land (meaning: at a company willing to pony up for licenses), I'd
consider a GFS2 cluster shared out via NFS.  Or maybe an OCFS2 NFS
cluster.  If at a company using CentOS, I'd consider an OFCS2/NFS
cluster or heartbeat/XFS/NFS.  For home? XFS (or JFS if you like).  But
then, I'm willing (and capable) of supporting the mess I create.  It all
depends upon one's comfort level with getting out of a jam when one
strays out of the "sweet spots" of available help...
