Hello,
Version is GL210R004.
I dont know, because the disk are in the state a few months ago.
I have two pool, one pool with 3 disk in that state Degraded (LEFTOVR), the pool 2 is ok, and have 2 disk (Dedicated Spare) so i dont understand why not the storage use this disk Spare to rebuild or replace the disk degraded.
Sorry i dont know much the storage.
Regards
