If it finish without errors, you might be able to use btrfs-select-super - try btrfs-zero-log btrfs-select-super and btrfs-zero-log isn't compiled by default, so you need to grab the sources and compile them with "make btrfs-select-super" and "make btrfs-zero-log" -- Fajar -- 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
