You probably hit:
TAKE 959978 - growing an XFS filesystem by more than 2TB is broken
which unfortunately probably was never backported to the centos5 xfs
module. Hmm maybe I should do that. :(
Dave, do you remember what the fs looked like after hitting that bug?
You may want to read through the "Repairing a possibly incomplete
xfs_growfs command?" thread from earlier, on this list...
I assume you need to try to recover this fs...? If so I'd not try
shrinking or doing anything else to the fs until there's a chance to see
what shape it's in at this point.
