I know there's the potential for snapshots causing a lot of IO, but I think what was happening here was beyond that. I had noatime on, and was not running even any readonly disk access. Also, I am pretty sure that the disk access light was off, with the cpu at full utilization.
Other IO intensive operations such as updatedb or a raid1 check don't pin the cpu and don't make the machine unresponsive. > Did prior releases of the kernel behave better? I've never had an Ubuntu kernel where this worked well, but I haven't tried every release, and obviously am not using it at the moment. I'm willing to retry it sometime. -- Martin <http://launchpad.net/~mbp/> -- lvm snapshot on top of md raid 1 causes nearly 100% cpu usage https://bugs.launchpad.net/bugs/113713 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
