Depends on how you want it to run. Short version is that gfs on dom0
is not required to have gfs on domU, and vice versa.

If you want to have gfs on domU only, you can have drbd on dom0
active-active, maps the resulting block device (/dev/drbd1 or
whatever) as domU disk, and use that disk for gfs on domU. So you need
drbd on dom0 only, and gfs on domU only.

Another alternative, if you only want to test gfs, you can just use
plain files/LVM/partition on dom0 side, and have domU handle both drbd
and gfs.
