# NFS rpc.mountd Options

Under certain circumstances, users may need to change or remove NFS `rpc.mountd` options.

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

Modify NFS rpc.mountd Options

Caution: The Appliance Controller manages the `/etc/sysconfig/nfs` file. Any edits made directly to this file will be lost when the Appliance Controller is restarted, or when changes are made to NAS configurations.

1. Log in to the Appliance Controller CLI on the node you will configure the `rpc.mountd` options:
2. To change the NFS `rpc.mountd` options, enter:

nas rpcmountd options change <option> [option ...]

The parameters are:

`<option> [option]` | If changing multiple nfs.mountd options. When entering options: Options are space separated Only a subset of nfs.mountd options are supported

Considerations:

- Changes to `nfs.mountd` options will restart NFS services and disrupt NFS access to shares. You must unmount all NFS clients prior to doing issuing this command.
- The nas nfsmountd change command can only be issued from the 'master' node in a NAS cluster.
- When you issue the nas `nfsmountd` options change command, all previous options are replaced with the new options.
- To append additional `nfs.mountd` options, you need to enter the current options along with new options

- Currently supported (valid) options with the `nas rpcmountd options change` command are:

  '-d', '--debug'

  '-o', '--descriptors'

  '-n', '--no-tcp'

  '-r', '--reverse-lookup'

  '-t', '--num-threads'

  '-u', '--no-udp'

  '-g', '--manage-gids'

  Consult the `nfs.rpcmountd` man page for proper arguments and use of these options:

  `nfs.rpcmountd` man page

  Example: Add --manage-gids and --no-udp options

  > nas rpcmountd options change '--manage-gids --no-udp'

  This will disrupt NFS access. Please unmount all NFS clients prior to doing this. Continue (yes/No)? yes
