BTRFS Failure after force restart

Oh, ok. Thanks, I didn’t know about this.

Is “Defrag” what I think it is? If it’s defragmentation, this shouldn’t be enabled for a SSD.
Should I disable it or is it something else, not classic defragmentation?

[EDIT]
I found this: Btrfs defrag on SSD (Solved) - #2 by BluishHumility

It says it’s ok to have it on, but I’m not very convinced it’s really ok.
