https://bugzilla.kernel.org/show_bug.cgi?id=20902 Summary: High Product: File System Version: 2.5 Kernel Version: 2.6.36-020636rc8-generic Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 AssignedTo: fs_ext4@xxxxxxxxxxxxxxxxxxxx ReportedBy: martinmoerch@xxxxxxxxx Regression: No I'm running an ext4 filesystem on a LUKS device that sits ontop of an LVM device. The filesystem is created with no special options and is used for storing filessizes ranging from 1KB to 20GB. I experience extremely high IO wait times when trying to write files to the filesystem, bot locally and through Samba. The problem can be reproduced by doing a reboot, unlocking with cryptsetup, mounting the filesystem and then writing a file to any directory on the filesystem. The 'cp' process stalls for almost 15 minutes and then returns to normal and completes the copy eventually. If I then 'cp' the same file again, there's no problem at all and the copy goes through like normal without stalling for 15 minutes. Rebooting and doing it again, reproduces the problem immediately. I've attached anything that might be of interest to anyone who'd want to look into this. -- 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
