NOT true. I'm setting up something very similar right now with a
brand-spanking new Poweredge 4600, external 2TB u160 storage array, and
Redhat 8.0. I'm mounted it as both ext3 and reiserfs so far, and they can
both use the full 2TB (minus a couple of small quorum partitions for using
kimberlite or redhat AS clustering later).
BTW, has anyone here gone through the trouble of recompiling a redhat 8.0
2.4.18-18 kernel with XFS, and if so, what version of XFS? Can you share out
stuff with NFS fine after that?
