The first thing I'd like to do is give you a patch to completely disable the tree log replay and give you the chance to backup critical data. Do you already have a backup of the critical things on this drive? The problem you're hitting is that tree-logging code is trying to replay an fsync of a file, but it can't find the file to replay. This could be a small and localized corruption or it could be a larger problem. We'll have to fix things one at a time to figure it out. The easiest way to move forward would be to save a complete copy of the FS with dd, but that's probably not very easy given the size. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
