Apps That Rely On Ext3's Commit Interval May Lose Data In Ext4

Posted by timothy on from the heavy-trade-off dept.

cooper writes "Heise Open posted news about a bug report for the upcoming Ubuntu 9.04 (Jaunty Jackalope) which describes a massive data loss problem when using Ext4 (German version): A crash occurring shortly after the KDE 4 desktop files had been loaded results in the loss of all of the data that had been created, including many KDE configuration files." The article mentions that similar losses can come from some other modern filesystems, too. Update: 03/11 21:30 GMT by T : Headline clarified to dispel the impression that this was a fault in Ext4.

    Clearly I won't be using Ext4 for a long while. The attitude of T'so indicates that he doesn't really know the purpose of a file system. It doesn't matter how capable this guy is, he is an idiot.

    Suggesting that this is the domain of the application is crazy. Writing a bunch of small files is par for the course for many applications, suddenly all these apps need to be reworked? The app wrote the file, probably received no error messages indicating that something might be wrong, and closed the file, and yet the file system is loosing data. The file system is suspect.
