This suggests that you plan to create partitions like /dev/sdX1 on the
RAID-6. If you really do (which is not a good idea IMHO because it buys
you nothing) you will have to be extra-careful to not mess up the stripe
alignment. I think the better option is to create the XFS directly on
/dev/sdX without partitions.

cheers,
