I did an xfs_repair now, and everything was OK. But strange was, in
Phase 4 the AGs were not checked in order:
AG 2
AG 1
AG 0
AG 3
AG 4
AG 5
Is that normal?

Could be xfs_repair running with multiple threads in parallel?
cheers.

Would it ever do that? There's no performance advantage in that, as that
operation is disk I/O bound, isn't it?

Be worth reading the paper here:
