https://bugzilla.kernel.org/show_bug.cgi?id=194511 Bug ID: 194511 Summary: filesystem slow down Product: File System Version: 2.5 Kernel Version: 4.4.44 und 4.8.??? Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext3 Assignee: fs_ext3@xxxxxxxxxxxxxxxxxxxx Reporter: dieter.ferdinand@xxxxxx Regression: No hello, last month i try to update to the last kernel 4.4.xx. but that was a big fault. after the update, it looks fine, but after some time (ca 30 minutes after a restart of the server, the system slow down and i need to much time to copy files to the drives. i test the speed: read usb >30000 MB/s read sata >100000MB/s write filesystem usb ca 1 MB/s write filesystem sata ca 1 MB/s this month i used a rescue-system with a kernel 4.8.??? to change a harddisk-config on a server and i get the same problem: to backup, format and restore a filesystem with less then 1 GB data i need over 2 hours. the initialisation of a 160GB ext3-filesystem need over 30 minutes. this is impossible! at the same time, a raid is rebuild with over 100 MB/s. i stop the rebuild, but this have no effect to the write-speed of mke2fs to init the filesystem. at last, i reinstall the system in less then 30 minutes two times again because the system don't boot after my changes. i think a selinux-problem. this systenm use kernel 3.10.0 at the moment without problems. after two days, i install the kernel 3.18.47 from kernel.org to have the latest 3.xx kernel and this kernel works fine and since installation without problems. only, i must deaktivate initramfs, but i think, that is no problem of the kernel and i have no time to analyse this problem at the moment. goodby -- You are receiving this mail because: You are watching the assignee of the bug.
