We had a chat about btrfsck running clean in some cases. Sure enough, it did for me on a filesystem I had just created. But on existing filesystems I've been using for a while, it never has for me has per the example above. I've added some info to: https://btrfs.wiki.kernel.org/index.php/Btrfsck Two questions: 1) are others seeing errors like these: Extent back ref already exists for 2148837945344 parent 0 root 257 leaf parent key incorrect 504993210368 bad block 504993210368 2) do you know how bad each one is, and should they all be picked up by a scrub? (I'm under the impression that they were not for me) I'm happy to further update the wiki on btrfsck with info you can contribute.
