It sounds like something changed your partition table as well as your
filesystem. Putting the partition table back in place first probably
would have been the better first step, in retrospect.
I can't tell for sure, though, what you've done (did you reparition?
mkfs? with which tools? what was the xfs_repair output?) so I'm not
sure what to tell you at this point.
