RAID is degraded but all disks are OK

Post by wishindo »

My RAID 5 on my F5-221 NAS is degraded but the member disks are all OK. How do I start rebuilding the array?

Check which drive is abnormal on the storage pool. You will need to replace the failed drive and perform an RAID repair in time. It is also possible that the RAID is degraded due to a drive that is not plugged in tightly.

The status for all member disks is listed as "good" in the storage pool view. That's what "all disks are OK" meant.

I'll try unplugging and replugging once I can bring the NAS down. It's in use right now.

I tried the above and it has worked. RAUD status is normal now.
