Problem
In Storage & Snapshots > Storage > Disks/VJBOD > Disks, I see the following icon on my disk and when I hover over the icon the message says, "The installed disk is unsuitable for rebuilding RAID Group [number]. Install another disk to rebuild the RAID group."
Why is this happening and how can I resolve it?
Causes & Solutions
1. Insufficient disk capacity
Cause: The disk capacity is too small, which may cause the RAID group to fail to rebuild.
Solution: Replace the disk with another disk with a capacity greater than or equal to the disk with the lowest capacity in the RAID group. It is generally recommended that all disks in a RAID group have the same capacity.
2. S.M.A.R.T. errors
Cause: The disk has S.M.A.R.T. errors.
Solution: Replace the disk with a new disk that has a "Good" S.M.A.R.T. status.
To check a disk's S.M.A.R.T. status, go to Storage & Snapshots > Storage > Disks/VJBOD > Disks, select the disk, and then click Health.
3. Other ongoing operations
Cause: The RAID group is currently performing other operations (such as syncing) and therefore is not ready for rebuilding.
Solution: Wait for other operations to complete before initiating the rebuild process.
If the system does not automatically rebuild the RAID group, you can manually initiate the process:
- Go to Storage & Snapshots > Storage > Storage/Snapshots.
- Select the storage pool containing the RAID group.
- Click Manage.
The storage pool management window opens. - Click Manage > Recover RAID group.
