Restore Your System

When you need to restore the Appliance Controller configuration in a clustered NAS environment, you will need to synchronize the sync data to all nodes in the NAS cluster, and then recreate the NAS cluster. However, you can only run the "system restore" command on the master node, and only if it's first removed from the NAS cluster before attempting using the system restore command on the master node.

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

    3. nascluster show

  3. Record current NAS cluster settings.
  4. Delete the NAS cluster. See Delete a NAS Cluster (return to non-clustered state).
  5. Perform a "system restore" on the master node. At the prompt, enter:

    6. system restore

    > system restore

    Are you sure you want to restore the configuration from backup (Yes/no)? Yes

    Restore of configuration in-progress ...

    Restore of configuration successful

    Restarting services ...

    Stopping all services . . .

    keepalived

    haproxy

    winbind

    smbd

    ctdb

    console

    appliance_controller

    Starting all services . . .

    appliance_controller

    console

    ctdb

    smbd

    winbind

    haproxy

    keepalived

  6. Recreate the NAS cluster (using the settings recorded earlier in step 3). See Task 1: Create a NAS Cluster.

If you need to restore the Appliance Controller's configuration file from a previous backup, run the system restore command. The most recent configuration file will be in the /var directory. However, if you do not want to restore from the most recent configuration file, make sure that the file from which to restore system configuration is in the /var directory.

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

    3. system restore

    > system restore

    Are you sure you want to restore the configuration from backup (Yes/no)? Yes
