I have a DS220+ with 2x 6TB drives in RAID. I used some bad RAM, and now the volume is read-only and won’t restore. I was resigned to backup the data, create a new volume, and restore the data, but I had an idea – will this work?: Basically, I use one of the two drives as its own backup. I pull out one drive and save it, I wipe the other drive and create a new volume, then pop in the drive with files from the old volume, and copy the files over, and then recreate the RAID. Should that work? Any obstacles I should watch for?

    I’m like 99% sure it’s RAID1, but it might be SHR. I’m sure it’s not RAID0.

      Quick way to tell: when it was functioning, did it appear as a 6, or a 12 TB drive? If it appeared as 12, that means you were using RAID 0.

      Did you have 6tb or 12tb storage available?

          Barring some messed up partitions, you should have been using RAID 1.
