Unmounting & running xfs_repair doesn't report any corruption. I see that this was last reported here http://oss.sgi.com/archives/xfs/2015-12/msg00224.html Unfortunately we dont have a reproducer, but this issue happens periodically. We can add more debug prints & allow this issue to happen again. Can you pls suggest any options to debug this further?
