We upgraded from cDTO 8.3.2
Something to add: existing v4 clients (ie those that mounted the share before ONTAP 9 upgrade) are just fine after the upgrade, only brand new NFS clients are having issues.

That wouldn’t cause hangs though.
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?
