NAS Backup failed after changing the credentials for the NAS device


NAS credentials were updated and post which the backup failed with error Phoenix 370. Error: Client internal error [mkdir /mnt file exists]. You need to check backup logs for additional information.

  1. Login to the NAS proxy.
  2.  Shares are mounted under: /var/Phoenix/NAS/mountpoint/ <mount name>.
  3. To check for the stale entries of any mounted shares,  run the command : df -h. This will give us an output for stale file handles for /mnt on NAS proxy.
  4. Unmount the share with this command: umount /var/Phoenix/NAS/mountpoint/<mount name>
  5. Initiate a backup after doing the above steps.

Note : Reboot will help in this condition if you are able to unmount the drive.
