Hi Chris, as you requested, you can pull my latest patches from
git://git.jan-o-sch.net/btrfs-unstable You'll find three branches to choose from: "scrub", containing the backref walking code and patches to fixup nodatasum errors. They have been sent to the mailing list lately as "[PATCH v8 0/8] Btrfs scrub: print path to corrupted files and trigger nodatasum fixup". Next, there is a "raid1-repair" branch, adding code to write back good data as we get it to failed disks in a raid setup. This was sent to the list as "[RFC PATCH 0/4] btrfs: Suggestion for raid auto-repair" earlier. I added a missing unlock (pointed out by Ian Kent), which should be the only difference from the previous patch set. Andi Kleen has looked over the raid1-repair series and suggested adding some threshold to avoid flooding the console with errors from the repair attempts, in case the drive is really bad. This is definitely important, but we can also add them later (that's my opinion, at least). I'm planning to do more tests with sata fault injectors. I should get some within the next days, hopefully. I'd like to see the impact of flooding, which will make it easier to come with a good solution for it. The combination of both branches mentioned is the for-chris branch. It has the scrub patches first, followed by the raid1-repair patches as contained in the separate branches. The last commit in this branch is an integration commit, improving nodatasum fixup for a corner case (detailed description is in the commit message).
