Should check the IMT...

refers to http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=1035160

and that you should be on GA 6.8 and

Supported Kernel version:- kernel-2.6.32-642.el6.x86_64 Supported NFS-utils version:- nfs-utils-1.2.3-70.el6.x86_64 Supported libtirpc version:- libtirpc-0.2.1-11.el6.x86_64

This is for NFS4.1...which you may or may not be using....worth checking into.

Hi All,

We upgraded our 6 nodes cluster to ONTAP9 yesterday. Today I
discovered some freshly installed CentOS 6.8 hosts not being able to
mount file shares via NFS v4 protocol. The mount command just kind of
hangs. I verified it's not a connectivity issue, ie connections to the
filer's port 2049 are possible.

Also NFS v3 works just fine.

Did anyone experience anything like that?

Cheers,
Vladimir
