Hello all,
My RS1221+ suffered a Storage Pool crash today so look for advice on how to recover it as the symptoms of this one are new to me.
Configuration:
Storage Pool 1, Volume 1 = 6 x SSDs in SHR1
Storage Pool 2, Volume 2 = 2 x HDDs in SHR (mirrored backup of Volume 1)
Event:
Overnight the grid power was going nuts for a while and so the UPS was kicking in and out repeatedly. Eventually DSM threw an error on SSD6 as it happened to be doing a 6-monthly data scrub at the time and I guess the constant commands from the UPS were just too much.
No drama, (I thought this morning) I just clicked on the 'repair' and last time I looked it was almost done. Easy.
Then the grid went wild again later in the day and after constant UPS interruptions DSM spat-out SSD2. Ouch. All services stopped, containers, backups, home assistant, the lot. At least I got the multiple warning emails.
The bit that is new to me is that when I try and access the NAS I get as far as the login screen, then the password screen, before it just spins away for minutes and dumping to a white web screen.
I'm not so worried about the data on Storage Pool 1 but it I can still recover it from where it resides that would be ideal. Otherwise using the backups stored in Storage Pool 2 (last 2 drives in the same device) would be reasonably quick across the backplane - if I could get into DSM. Oddly I can still see the files on the 'bad' storage pool (Pool 1) over SMB.
The last resort would be starting afresh with both storage pools (ie losing the backups on the 2xHDDs in Storage Pool 2, located in the last 2 bays) and recovering everything from scratch from my final backup location, over a slow network connection.
Basically I want to get DSM working again on Storage Pool / Volume 1.
Any ideas from the wise?

[Yes, losing Home Assistant is causing panic etc...]
