Issue Summary

This article provides instructions for preventing storage drives from unmounting in WRN-1632(S) and WRN-816S.

Resolution

To prevent storage drives from unmounting:

1. Download the newfstab_update.sh file (attached to this article) and save it to the desktop of your WRN.  
2. Unplug all USB sticks or external hard drives.  
3. Right-click the desktop of your WRN and open Terminal. 
4. Run the following command: 
   
   sudo chmod +x /home/wave/Desktop/newfstab_update.sh
   
   This allows the script to be run as an application. 
    
5. Run the cat /etc/fstab command to view the contents of the file.  
6. Ensure the file contains the following mount points: 
   
   
    

7. If the mount points match, run the following command: 
   
   sudo /home/wave/Desktop/newfstab_update.sh

   IMPORTANT: Running this script will briefly stop and start the media server. 
   During this time (a few seconds), no video will be recorded.

   If the mount points do not match those above, the script cannot be run on this unit and no further action is needed.  

8. When prompted, enter your credentials.  

9. When the script is finished, run sudo cat /etc/fstab again to verify the mount points have changed.
   Example: (UUIDs will vary, but the format will remain the same) 
   
   UUID=12345678 /mnt/sda ext4 defaults,nofail,x-systemd.device-timeout=60s 0 2
   
   UUID=56781234 /mnt/sdb ext4 defaults,nofail,x-systemd.device-timeout=60s 0 2
   
   UUID=14235867 /mnt/sdc ext4 defaults,nofail,x-systemd.device-timeout=60s 0 2
   
   UUID=23146758 /mnt/sdd ext4 defaults,nofail,x-systemd.device-timeout=60s 0 2
    

   NOTE: If your system has less than four drives, only the lines corresponding
   to the connected drives will update with UUID mount points. The remaining 
   lines will not change and will stay the same after the script runs.
