I've got a BTRFS filesystem that was corrupted by a RAM error (I discarded a DIMM after doing all the relevant Memtest86+ tests). Currently I have been unable to get btrfsck to work on it and make it usable again. But at least I know the data was corrupted which is better than having the system keep going and make things worse.
Agreed. Is development effort being devoted to Btrfsck at the moment? I know it was long delayed and still not considered complete when released, but that was quite a while ago. I also know that online fsck is among their longer-term project objectives, since a full off-line scan and repair of today's high-capacity drives is considered unacceptably time-consuming in some environments.
