Tarak, could you do me a flavor, and reread, what I've already written =

Why do you insist in creating partitions in an already partitioned devi=
ce?

Just do:

mkfs.xfs /dev/md0
mount /dev/md0 /mnt

and be done. It *is* that easy.

md0p1 and md0p2 are obsolete in this scenario. If you need a more compl=
icated=20
setup, check out lvm.=20
