With nothing else running on the box only my rsync test the Seagate single drive causes iotop to report between 10 and 15 times the io percentage as the Western Digital drive when both are set to transfer at the same speeds. So any transfer that would cause ~9-10% io load on Bravo is causing Alpha to become io-bound. Anything higher on bravo such as to the 20% range will cause Alpha to fall behind and stay io-bound for an extended period of time.
Is there a way to get more debug output for the hard drive io? Such as determining if one of the chips between the hard drives and the cpu have start to throw a high percent of errors on hard drive write operations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/815540 Title: Server becomes unresponsive after spawning 16 ksoftirqd processes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/815540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
