Many months ago, I had a power outage in my home, and when my server boot back up, its SSD cache was unmountable. I found out that Btrfs is very sensitive to sudden power outages, and got a second NVMe drive to add to the cache pool for redundancy. Losing the appdata folder really hurt, and I had to remake most of my Docker containers from scratch.
Now, the same thing has happened again (power outage), and neither of the NVMe SSDs are mountable. I have scoured the forums, and all advice seemed to point here. I have followed all of those steps, and at each step, I see a message something to the effect of "no Btrfs filesystem found." Both drives were encrypted (via Cache Settings), which I assume interferes with the data recovery.
Can any kind soul give me some guidance? I'm trying to do a restore from a cloud backup, but it's months old, is taking forever, and may ultimately fail. I would be beyond grateful if I could recover that appdata folder from either of my 2 drives (which should each have the data). I have not at any point reformatted the drives.
