Managing the NFS service
You can enable or disable the NFS service and specify the NFS versions to support, including NFSv3 and NFSv4. NFS settings are applied across all nodes in the cluster.

NFSv4 can be enabled non-disruptively on a OneFS cluster, and it will run concurrently with NFSv3. Any existing NFSv3 clients will not be impacted by enabling NFSv4.
