Asking for help with "RAID level unknown" & "volume root is degraded" errors
Hello, After a firmware update, my Readynas 104 is unusable. I have the following error message: "Volume data RAID level unknown" (see capture). Diagnostics revealed that a disk has "pending sectors"...

when I start with 4 disks (exlcuding the one with pending sectors) I get "volume root is degraded".
I think you must mean 3 disks, since there are only four bays total in the RN104. Are you able to access your data when you boot the system this way?
To clarify - a "degraded volume" is one that is no longer protected by RAID redundancy, but which is still accessible. If you are seeing "corrupt root", then that is another matter.
Hello and thank you for answering.
You're right, I meant 3 disks, sorry.
When I start with 4 disks I get the "disk 2 has pending sectors" and when I start with 3 disks (excluding the 2nd), I get "Volume root is degraded" and "md/raid:md127: failed to run raid set." when I use the diagnostic from RAIDAR.
I cannot access my data either with 3 or 4 disks.
I get to the 1st folder level (Videos, Pictures, ... but I click I get a network error message saying windows cannot access (error code 0x80070043).
