# Manage NAS Services

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

Enable NAS

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:

Set password required for 'sysadmin' user

Password:

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

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`>.

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.

Disable NAS

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

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.

Enable NFS Services

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.

1. Log in to the Appliance Controller CLI on the node you will disable services.
2. Enter:

> `nas nfs enable`
