Hi, I have success with setting the block-io-scheduler to something different than »deadline« for each block device in our raid arrays. This is with kernel: 2.6.32-24-server
I tried »noop« and it worked fine for me. This is not reproduced yet, because a backup lasts more than 12 hours each. Today I'll test cfq and report. To read the current or set the scheduler for each block device through /sys/block/sd*/queue/scheduler. On the other hand you can set it globally with the boot option: »elevator=cfq« (or »noop« or »anticipatory«) Good luck Lars -- "Smbd","kjournald2" and "rsync" blocked for more than 120 seconds while using ext4. https://bugs.launchpad.net/bugs/494476 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
