It should be fixed in 4.19.8+ https://lwn.net/Articles/774440/ I'm not sure off hand how to fix the corruption once it's happened; and I'm not even sure if it's a contributing factor to the power failure or not. It is disappointing that btrfs check has no way to iterate or try to infer a correction for a bad leaf, but it's not certain how badly damaged that leaf is yet. You can output it 'btrfs insp dump-t -b 448888832 <dev>' and remove file names before posting it; this might help a dev sort out what the problem is. -- Chris Murphy
