Official NetApp NFS support statement is that we support any client that follows the RFC specification. No custom kernels. RHEL/CentOS 6.8 should be fine.
I’d look into a getting a packet capture of the hang to see where they are occurring in the process.

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?
