It would help to know the actual values here, so some df/quota/
repquota output, if you still have it.

quotacheck is a noop on XFS, yes.

Thats correct.

du is only looking at file sizes for files it can "see", so its
not accounting for several other things (like inode metadata,
extended attributes, unlinked but open files, etc). So it is
not "obviously wrong" until we can discount those factors, but
its possible something is wrong.

I would first run quot(8) from the quota-tools package (Redhat
in their infinite wisdom decided not to ship that tool, so you
may need to build from source if you use Redhat) and see if its
notion of used space matches either of the other two tools (its
using a different interface again).
If quot(8) disagrees with quota(8)/repquota(8), I would then do
an unmount and xfs_repair to see if that clears things up.
cheers.
