You probably hit: TAKE 959978 - growing an XFS filesystem by more than 2TB is broken http://oss.sgi.com/archives/xfs/2007-01/msg00053.html 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. -Eric
