Exactly. See also the Postings of Richard van den Toorn on the list. Summary: Mount is locking when upgrading from 3.8.x to 3.9.x Unfortunately I was unable to do a git bisect because somewhere on the way the behaviour changed from locking to "permission denied". If you give me a hint if this behaviour should be marked as good or bad I can continue bisecting! > - have you figured out exactly where the failure happens?: No because I have not been able to do git bisect to the end. > - which version of NFS are you using?
