Readynas 314 Degraded volume

Morning, 

I recently ran a volume defrag (unrelated I assume) 

 

I have powered on my 314 last night and am getting a warning in the webpage and via the LCD that the volume is degraded.

All 4 WD drives are online and showing as green in the webpage.

 

I have downloaded the logs, and taken a quick look at the smart_history.log.... a trimmed version of the log is below.

I assume from these logs that WD-WX31D55DF4Y7  is currently reporting errors and should be replaced?

    It is reporting the errors, and likely is the cause of the problem.  You could also look in system.log and kernel.log for disk errors

     

    You might want to test it with Lifeguard in a Windows PC. If it passes the long non-destructive test, then try the destructive full write-zeros test - it can pick up issues that the non-destructive test misses (and vice versa).

     

    Also, see if it is still under warranty (3 years).  If the disk is new, then exchange it with the seller (since a warranty replacement from WD will be a recertified disk with a short warranty).
