Manage NAS Services

This topic provides information to help you manage your NAS services.

By default, NAS services are not enabled on your node to avoid running services that are not needed and might trigger a site security scanner (your site might refuse to have any kind of NFS server services).

You can enable or disable all NAS services as needed.

Do the following to enable NAS:

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

    > nas enable

    Example output:

    NAS services will take over the following config

    files and custom modifaction will be lost:

    /etc/exports

    /etc/samba/smb.conf

    /etc/nsswitch.conf

    /etc/sssd/sssd.conf

    /etc/ldap/ldap.conf

    Are you sure you want to enable NAS? (yes/No)? yes

  3. Enter yes to enable NAS:

    4. Set password required for 'sysadmin' user

    Password:

  4. Enter the password for the sysadmin user account (default is sysadmin), and click <ENTER>.

    5. You will be asked to enter the password for the sysadmin account again:

    Enter password again:

  5. Enter the password for the sysadmin user account again (default is sysadmin), and click <ENTER>.

    6. You will see the following confirmation items indicating that NAS has updated the registry, and NAS services have started:

    Nas enable registry set

    Waiting for NAS to be runnable

    NAS services are now enabled and running.

    The process is complete.

Before you Begin

Before you disable NAS, the following conditions must be met, or you will see error messages on attempting to disable NAS:

  • Authentication needs to be local.

  • Ensure you have no existing shares defined. If you do you need to remove all of them with the share delete command.

  • Make sure the server node is not part of a cluster. If you need to leave the cluster, use either the nascluster leave or nascluster reset factory-defaults'

Do the following to disable NAS:

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

    > nas disable

    3. You will see the following confirmation items indicating that NAS has updated the registry, and NAS services have stopped:

    NAS services are now stop and disabled.

    The process is complete.

You can disable SMB or NFS services on a single node if you do not want them to be actively running. If you decide to use these features after disabling them on a node, you can also enable SMB or NFS services.

By default, SMB or NFSv3 services are enabled. To check whether these services are enabled, use the system status command. See View System Status.
