Q: Why is the volume status degraded?

2025-12-08




The NAS volume status is indicated as "degraded" due to one or more of the following reasons:

 

1.Hard Drive Failure 

   One of the drives in the RAID array has failed or is no longer functioning correctly. In a RAID setup, the failure of a single drive can cause the entire volume to enter a degraded state.

 

2.Drive Disconnection 

   A hard drive may have become disconnected or is not properly seated in its bay. This can occur due to physical disturbances or loose connections.

 

3.Sector Errors

   One or more drives may have developed bad sectors or other read/write errors that have led to the RAID controller marking the volume as degraded.

 

4.RAID Rebuild Interruption

   If a RAID rebuild process was initiated and then interrupted or failed, the volume can enter a degraded state.

 

You can check the above scenarios on the ADM-Storage Manager-Volume page.
