https://bugzilla.kernel.org/show_bug.cgi?id=39072 Summary: jbd2 writes on disk every few seconds Product: File System Version: 2.5 Kernel Version: 2.6.39.2 arch Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 AssignedTo: fs_ext4@xxxxxxxxxxxxxxxxxxxx ReportedBy: marcin2006@xxxxxxxxx Regression: Yes If I don't specify in /etc/fstab some large commit value, jbd2 is killing my disk, I think even more frequently than default 5 seconds. Mount says: /dev/sda6 on / type ext4 (rw,noatime,user_xattr,acl,barrier=1,data=ordered) In iotop jbd2 constantly appears on top and sysctl vm.block_dump=1, dmesg | grep -e READ -e WRITE shows that jdb2 is writting on the disk every few seconds and only jdb2. I have IBM ThinkPad x30 here, but simmilar thing happens on my PC. I guess it should not write to disk if there isn't really anything to write. It is impossible to spin-down the HDD. I have a minimal archlinux system here with xfce, running from failsafe entry from GRUB, while pursuing this problem I have killed X, killed all daemons, swapoff, unloaded acpi modules, usb modules and other - nothing helps. I'm not even sure what logs should I attach as people are complaining on different configurations for a year, it's all there: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/607560 https://bbs.archlinux.org/viewtopic.php?id=113516&p=1 -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
