The default/normal configuration of ext4 journals only metadata. This means that file system integrity is guaranteed but individual file content can be corrupted by a power failure or other hard crash. To update files that must be correct, one can write a new version, sync, and then use mv to replace the old with the new version. Since mv is a metadata operation, it is guaranteed to either have happened or not after crash recovery. The journal_data option provides full protection, but I suspect it is not a practical solution for normal usage. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
