<p class="MsoNormal">Hi All,<br clear="none">
<br clear="none">
We upgraded our 6 nodes cluster to ONTAP9 yesterday. Today I<br clear="none">
discovered some freshly installed CentOS 6.8 hosts not being able to<br clear="none">
mount file shares via NFS v4 protocol. The mount command just kind of<br clear="none">
hangs. I verified it's not a connectivity issue, ie connections to the<br clear="none">
filer's port 2049 are possible.<br clear="none">
<br clear="none">
Also NFS v3 works just fine.<br clear="none">
<br clear="none">
Did anyone experience anything like that?<br clear="none">
<br clear="none">
Cheers,<br clear="none">
