ReadyNAS 312 Frozen on disc replacement

Hi! I had a failed disc on the unit so decided to replace both with same size 3TB WD red drives. Replaced the first following the standard procedure. No problems, left it for a day to ensure all was working, then replaced the second. System is now offline and not accessible after 14 hours, and only 600MB on disc. On replacing the second, the logs showed removal of a disc, the replacement disc being added, then nothing. On replacing the first I had a message to the effect data was re-syncing, and then that it had been completed (within 1 hour, so faster than I expected). This time no such message, just "Device is offline - please wait"

I have backups but this is not how it's supposed to be. Should I shut down, remove disc 2, restart, and try reinstalling the disc again?

Cheers

Not as far as I know.

Some users report problems with the DM disks. Perhaps test that disk too.

Did the resync only take 1 hour with all the disks you tried?

You could try that.

It's possible that one of the new disks might be faulty. I assume you didn't test the new disks using WD Data Lifeguard Diagnostics?

Which firmware are you running?

  Thanks mdgm,
  
  No - I didn't test the new discs. Can't access the unit so not sure about the firmware. I recall updating in the last 6 months or so.

    Whatever you do you are going to have to test both new disks before proceeding.
    
    Wd lifeguard extended tests take a long time.
    
    I would power down, remove the disks, reinsert your old disk 2 (the one you exchanged second) and power on. This may get you back to the situation you were in after you inserted the first new disk. If at least one of the new disks is ok , and the old disk allows normal access to your volume, then you can try to insert a new disk again.
    
    Could you access the data after the first disk exchange?
    
    One hour is far too short a time for the resync to have completed, you were correct to be suspicious. Did you look and confirm that the volume was redundant at this stage?
