Hi Dave, http://www.spinics.net/lists/linux-xfs/msg00061.html Back in Dec 2013 you responded to this message saying that you would take a look at it. Was a fix for this ever issued? I'm seeing very similar stacktraces: Feb 7 00:27:32 node008-cont001 kernel: [83405.490909] INFO: task umount:29224 blocked for more than 120 seconds.
