NFSV4

[lucifer6]

Have enabled NFSV4 on FAS8200 CDOT. 

1) Few servers are not able to mount with NFSV4. So also enabled NFSV3. I don't think this is a best practice to enable both. 

2) Once NFSV4 ,we are planning to enable Kerberos's. I dono if this works? do we need downtime ?

thanks

You can absolutely have NFSv3 and v4 enabled side by side.
