Unmount and Mount a File System Used by SN-NAS Shares

The following procedure applies to the Appliance Controller 2.1. or newer.

1. Execute the following commands on all of the nodes participating in a NAS cluster to stop the StorNext NAS services and the Appliance Controller:

   /usr/local/quantum/bin/snnas_service.py stop

   systemctl stop snnas_controller

   Note: You must execute the two commands in succession to prevent systemd from attempting to restart the StorNext NAS services (within 2 minutes).

2. Perform maintenance on the file system, and so on:

   1. Umount the file system.
   2. Configure the file system.
   3. Mount the file system.

   Note: Specific steps vary, depending upon the maintenance you need to perform.

3. Restart the Appliance Controller and the StorNext NAS services on all nodes:

   systemctl start snnas_controller

   /usr/local/quantum/bin/run-panshell -c 'system restart services all'
