Applies to

  • ONTAP 9
  • NFSv4.1
  • NFSv4.2
  • pNFS

Answer

  • Disabling pNFS will stop the NetApp server from handing out new layouts
    • Generally, NFS clients should not have an issue with this (and previously handed out layouts will still be used)
    • However, under certain conditions, clients who have already negotiated sessions with the server may continue to expect pNFS cabilities after it's been disabled
    • It is always a good idea to test new configurations on a test vserver before making changes in production
  • Enabling pNFS may add extra complexity
    • It is always a good idea to test new configurations on a test vserver before making changes in production

Additional Information

  • Disabling pNFS
    • ::> vserver nfs modify -vserver <vserver> -v4.1-pnfs disabled
