As for configuration registry: Filesystems are about files exactly same as sqlite and other databases are about records. Actually, files could be treated like some sort of records in some sort of very specific database (if we'll ignore some specifics). And we're, the users expect BOTH databases and file systems (at least these with journal) to care about our data and their integrity. And if file system does not wants to care about data integrity and rather tries to push data integrity question into another extra layer like databases instead of taking care on this question itself, why I should trust to such file system? Am I really expected to store my valuable data on a file system which prefers speed over data integrity? As for me, I want file system to provide data integrity on it's own, without REQUIRING extra layers like sqlite in applications. If file is written and closed, it have to be on disk. And as for me, gain of less fragnemtation and some gain in speed due to temp files in RAM are not worth of possible data losses due to over-aggressive caching (and ALL apps will be NEVER rewritten to use extra bloat like sqlite database just to keep data integrity). Sorry if some words are offensive or wrong but offer to use sqlite for data integity REALLY HURTS and RAISES QUESTION: why should I trust my data to such filesystem? As for now, I'm probably have to stick to ext3 even if this costs some speed but it does not loses data at least. P.S. I'm also using XFS _but_ only on computers where performance valued over data integrity and only with UPSes. And I'm unable to supply UPSes to each and every computer. So - in short, users need RELIABLE file systems which are providing reliability without extra layers like sqlite. Please do not disregard this simple fact. Sorry once more if this sounds offensive or whatever else. -- 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: Confirmed Status in ecryptfs-utils in Ubuntu Jaunty: Invalid Status in linux in Ubuntu Jaunty: Confirmed 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
