Comment 3 Cristian Iorga 2014-04-01 07:22:06 UTC 
This issue is generated by the fact that there is no support for NFS protocol v4.2 in kernel 3.10.x (on which the bug was opened), as such, the attempt the nfs server will fail.
Comment 4 Cristian Iorga 2014-04-01 07:22:52 UTC 
Issue is no longer present after the upgrade to Linux kernel 3.14.
