Had a power outage today and now my NVMe cache drive is unmountable. All app data is on this NVMe drive and now can't access docker. Diagnostic below.

Btrfs was already detecting data corruption before the issue, recommend running memtest first, then see here for some recovery options:

Sorry just got around to trying to fix this now. Ran the memtest and 1x16gb stick of ram was fried. Gonna run with only one stick for now and buy a second later.

 

Trying to follow the instruction you gave regarding recovery of the unmountable drive. I don't follow this line 

 

For a single device: replace X with actual device, don't forget the 1 in the end, e.g., /dev/sdf1

 

What am I replacing the X with in my situation? Sorry if it's obvious. I'm just learning this stuff now .

Nevermind.. I used the device name nvme0n1p1 and all the appdata files are in the temp folder. Gonna install the new drive now.

 

Thanks!!
