OK so I think I'm narrowing this down to just the systemd journal, and it's not checksums that are corrupted, it's the journal itself. [ 19.354354] systemd-journald[210]: /var/log/journal/8e4cbfea404512ae70096c6202c9a3bf/system.journal: Journal file corrupted, rotating. If I set systemd journald.conf Storage=volatile so that it stores journals only in memory, the problem is not reproducible. However, even after deleting all corrupt journal files, and a subsequent scrub reporting no errors, on each reboot (and mount of the filesystem) I get: [ 3.646448] btrfs: bdev /dev/sda6 errs: wr 0, rd 0, flush 0, corrupt 17, gen 0 So somehow the corrupt counter isn't being reset? And how would I go about setting /var/log/journal contents to inherit nodatacow? Possible?
