Tarak, could you do me a flavor, and reread, what I've already written last
time? Then, attempt to answer the single question below, please.

Why do you insist in creating partitions in an already partitioned device?
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 complicated
setup, check out lvm.
