I.e. in ordered mode, file data is always written before metadata, so the worst that could happen is a growing file's new data is written but the metadata isn't updated before a power failure... so the new writes wouldn't be seen afterwards. } Sonny, Thanks for you input! Is there an option in XFS,ReiserFS,JFS to enable ordered mode?
