Ok, so the problem is as expected - the secondary superblock in AG 5
is not verifying correctly. Can you run:
# xfs_db -r -c "sb 0" -c p -c "sb 5" -c p <dev>
And post the output?

Yup, that's a real corruption. Something has trashed a location
where inodes should be on disk.

There shouldn't be any XFS changes between 3.10.0 and 3.10.1, so I'm
not sure that's your problem. It looks to me like there's
pre-existing corruption on disk, and 3.10 is simply finding it. Have
you recently upgraded from an older kernel (i.e. older than 3.9)?
Cheers,
Dave.
