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?
Is it RAID0, or RAID1? If it’s the former, you’re fucked. No problem if RAID1.
Yeah that’s the really important detail here for sure
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.
It’s RAID1
Did you have 6tb or 12tb storage available?
6TB
Barring some messed up partitions, you should have been using RAID 1.
