Hmm, are you sure your disks are in the correct order inside md? Did
your devices perhaps get renumbered somehow - by plugging in new drives
perhaps. You have xfs inodes at block zero here, so this does not look
like it was the start of a filesystem to me.

Look at the start of all your component drives with od -xa, you are looking
for one which starts out with XFSB in ascii.
