So this happened...

 

 

 

I only have `appdata` and `system` set to `Prefer: cache` in shares, is there anything besides appdata restore/Docker/VMs that I'll need to attend to if I reformat?

Please post the diagnostics.

 

Here it is @JorgeB

 

Thanks for taking a look. Like I said above, I'm not against formatting the pool.

Also, just ran, in Maintenance Mode, a btrfs check with --read-only flag.

How did you make this happen?... (I want to make sure I don't?)...

Looks like a clear bitflip:

 

3034   =           1011 1101 1010
265178 = 0100 0000 1011 1101 1010

 

Run memtest, if you need to try and recover some data see here.
