File System unmounted / Volumes are unmounted error

Follow

Scope

This article discusses troubleshooting for the error: File System Unmounted or Volumes Are Unmounted

Cause

Below are a few reasons why this error may occur:

  • There was a power outage on premises, and the unit didn't properly shut down.
  • There was a hard reboot done recently.
  • If the device was recently rebooted to a larger device (over 5 TB in size). With more disks in the array, it takes longer to initialize. Allow 10 to 15 minutes for this to occur.

Solution

This error typically resolves after giving the device some time to catch up. If you are still receiving this error message after some time, reboot the appliance.
 
If the issue persists, contact Datto Technical Support for further assistance.
