I get a “spool degraded” error. System partition failure on my 2nd drive (2 WD 3TB Red drives, SHR configuration).
Well, DSM recommend I replace the faulty drive, and WD is sending me a replacement.
I do however need to return my failed drive. I would like to wipe it before returning.
Is it easy and since I’ve got the drives setup in SHR, does that mean I can wipe the faulty drive without losing all my data (assuming it’s all on drive one).
Then is it just as simple as sliding in my new drive?
This is the very stressful moment when all your data suddenly sits only on one drive. If that fails, it’s gone. At least external backup is recommended or at least BlackBlaze backup with unlimited online space.
Follow the instructions to erase and replace the faulty drive:
To repair a degraded storage pool:
- Go to Storage Manager > Storage Pool to confirm the status has changed to Degraded.
- If so, go to the HDD/SSD tab to see which hard drive has failed.
- Remove the failed hard drive and replace it with a new one.
- After the replacement hard drive has been installed, return to the Storage Pool tab.
- Select the degraded storage pool.
- Click Repair from the Action drop-down menu.
- Select the replacement hard drive which you would like to add to the volume. Then follow the instructions of the wizard to finish.
- If your Synology NAS does not support hot-swapping, please remember to power it off before removing and installing any hard drives.
- Existing data on the replacement hard drive will be erased.
