My bad, I am sorry, sometimes I forget to press the reply to all button.
It's still possible to recover, but more info is needed first.
Can you get xfs_db to dump the primary and a couple of secondary
superblocks?
I am glad to hear that, I have actually already extracted the files that I needed using UFS explorer, but I still would like to restore the filesystem if it is possible.

matching secondary superblocks from the contents of the primary that
it found.
And it found blocks with the correct superbloc magic numbers, but

they don't match the primary superblock that was found.

Can you get xfs_db to dump the primary and a couple of secondary
superblocks?
# xfs_db -c "sb 0" -c p -c "sb 2" -c p -c "sb 7" -c p <dev>
And post the output?
