# Enable NFSv4 Services

NFSv4 Services Overview

If you are using NAS failover for 2-node or scale-out NAS clusters, NFSv3 is automatically enabled. If you are using NFSv4 failover for a 2-node NAS cluster, you must manually enable NFSv4 services.

Note: MAC OSX clients do not correctly support NFSv4 mounts (ACLs are disabled by default). For MAC clients, Quantum strongly recommends you DO NOT enable NFSv4, but leave Scale-out NFS as-is, leaving NFSv3 enabled.

Note: For a list of all the Appliance Controller commands, see the Command Index.

Enable NFSv4 Services

1. Log in to the Appliance Controller CLI.
2. Enter:

> `nas nfsv4 enable`
