Check the archive for a thread entitled "Repairing a possibly incomplete
xfs_growfs command?" (It's pretty recent) I had this issue last week
and the XFS guys were able to help me out. Maybe there is something in
there that can help. Most notably, check the output of this command:
# xfs_db -r -c 'sb 0' -c p <device>
If you see agcount = 160, then the solutions provided may apply to your
situation as well.
Cheers,
Mark
