We have a 12 drive, 40 TB storage bay that all of a sudden encountered multiple drive failures On RAID 5. One drive we have replaced outright, while another two have SMART errors.
When the drives went down, the controller pushed everything into a foreign config. Now that we have put in a new drive, we can't import the foreign config back because of the two failed drives, and therefore can't rebuild.
My understanding is that these SMART error drives should be be recoverable in order to rebuild the array, but how can we start that when the configuration can't be imported?
