Catastrophic Raid5 loss at home. I had an array of 10 drives, 9 data + 1 parity lose 2 drives. It's a Synology SS1019+ with an external enclosure.

About 90TB in total, 90% full. Synology refuses to mount it. Drive errors galore in dmesg. I'm at a loss of what to do next.

I have a spare drive (all 12TB) just as a FYI, and am considering moving them all to a case I have with enough bays and to linux them into submission and try to recover something. But my MDADM foo is weak and the best I have is google right now.

I expect I'll spend most of today trying to recover a little before admitting defeat, RMA drives, and starting clean.

I'll admit I made many mistakes to get here. Only one drive parity, dumb. Not backing up when it told me, dumb. Not making sure everything I care about was in at least 2 places, dumb. And I had the gall to call myself "data paranoid"
