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.

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:

    3. 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:

      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
