I have a backup server with ~72TB of space.  Only about half of that is used.  Earlier in the week I got the following message and directly after the xfs filesystem was unmounted.Mar 15 15:15:47 kernel: Filesystem dm-0: XFS internal error xfs_trans_cancel at line 1164 of file fs/xfs/xfs_trans.c.

From running iostat -xd I can see the sdc, sdc1, and dm-0 listings counting down the r/s, w/s, and rsec/s values but am not sure if this really signifies anything.ANY help or guidance on this would be more than appreciated.
How can I tell if xfs_repair is stuck or still running?
