Mmmh, actually to be fair, this was the 2nd run, I didn't scroll back enough and missed the first run (doing too many recoveries at once, I'm getting mixed up). This first run looks like a lot more things happened: http://marc.merlins.org/tmp/btrfs_check_ds5.txt The amount of things that went wrong here are very worrisome, given that there were no issues with those drives and that array has been working for over a year without problems, until I recently upgraded to 4.11 :( Now mind you, despite the 21MB of things that got fixed, I still kind of have the expectation that btrfs check --repairs continues and fixes everything until the filesystem is clean again, just like e2fsck -f would, but I understand that this filesystem somehow got corrupted to a point that it's maybe not that simple to do so.
