[is btrfsck ready?] The aim is to have routine errors fixed online, the old thing of having a long fsck every certain number of days or certain number of boots has to go. But there will always be situations where a filesystem can't be fixed online.
There is, at least, a tool to pull data out of a btrfs given the number of the subvol (or tree?). I used this to recover /home subvol after my / subvol mysteriously went tits-up under 2.6.38, and btrfs refused to mount the filesystem at all (regardless of -o subvol &c options). So y'know, that wasn't a btrfsck, but it did what I needed.
