Not sure if one or both of my disks are failing or if there’s a bug in recent firmware (as some others have recently posted similar problems, I wonder if that’s a possibility?).
My Cloud Mirror Gen 2 - Firmware: 5.21.104
Noticed an orange light on Disk 1 yesterday. No alerts on the dashboard, but Disk 1 was showing as bad, and Disk 2 as good; RAID status is healthy.
Both disks passed a Quick Test.
Started a Full Test.
Disk 1 light is still orange, Disk 2 light is now off; both disks show as bad, RAID status still healthy.
Disk 1 passed the Full Test, Disk 2 failed the Full Test and now I have an alert for a SMART failure on Disk 2.
Rebooted the NAS (have tried warm and cold boot).
Disk 1 light is now blue, Disk 2 light remains off.
Disk 1 is now showing as good, but Disk 2 remains bad. RAID status remains healthy.
Any thoughts or recommendations on how to proceed? Should I replace one disk, both disks, or the NAS? Or wait to see if a firmware update addresses the problem?
I already have a full backup so I am not concerned about losing data, I’m just wondering what to do about the hardware.
