@helios I fail to see the fact that this would ever be a KDE bug. fsync only *helps*, it will never ever make sure that things will be solved permanently for good. The reason that a rename() is used with a temp file that *nothing* can get 100% durability (even using fsync). App developers want atomicity (with rename), because atomicity, they can get with a good filesystem design and implementation. 100% durability is impossible, power syncs during a fsync will also result in halfly written files, it will still suck that the rename() has been done at that point. Hence, as it is impossible to solve the problem of durability with fsync and because fsync is slow, it should not even be used IMHO. -- Ext4 data loss https://bugs.launchpad.net/bugs/317781 You received this bug notification because you are a member of eCryptfs, which is subscribed to ecryptfs-utils in ubuntu. Status in “ecryptfs-utils” source package in Ubuntu: Invalid Status in “linux” source package in Ubuntu: Fix Committed Status in ecryptfs-utils in Ubuntu Jaunty: Invalid Status in linux in Ubuntu Jaunty: Fix Committed Bug description: I recently installed Kubuntu Jaunty on a new drive, using Ext4 for all my data. The first time i had this problem was a few days ago when after a power loss ktimetracker's config file was replaced by a 0 byte version . No idea if anything else was affected.. I just noticed ktimetracker right away. Today, I was experimenting with some BIOS settings that made the system crash right after loading the desktop. After a clean reboot pretty much any file written to by any application (during the previous boot) was 0 bytes. For example Plasma and some of the KDE core config files were reset. Also some of my MySQL databases were killed... My EXT4 partitions all use the default settings with no performance tweaks. Barriers on, extents on, ordered data mode.. I used Ext3 for 2 years and I never had any problems after power losses or system crashes. Jaunty has all the recent updates except for the kernel that i don't upgrade because of bug #315006 ProblemType: Bug Architecture: amd64 DistroRelease: Ubuntu 9.04 NonfreeKernelModules: nvidia Package: linux-image-2.6.28-4-generic 2.6.28-4.6 ProcCmdLine: root=UUID=81942248-db70-46ef-97df-836006aad399 ro rootfstype=ext4 vga=791 all_generic_ide elevator=anticipatory ProcEnviron: LANGUAGE= LANG=en_US.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.28-4.6-generic SourcePackage: linux
