I've been waiting for some response from the Ubuntu team regarding a bug on launchpad, but it appears that it isn't being taken seriously: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/745785 We are running Ubuntu Natty 11.04 with KVM with our storage on RAID10 + drbd. While we were running the resync command, we could expect an IO block during every resync. I eventually disabled resync. Yesterday we had a kernel panic, which I am presuming may trace back to KVM and its interactions with RAID10. I run KVM on some other boxes with some built-in Dell hardware RAIDs. They have been stable for well over a year on Ubuntu 10.04. Here are the 11.04 current versions if that helps. kvm 84+dfsg-0ubuntu16+0.14.0+noroms+0ubuntu4.4 kvm-pxe 5.4.4-7ubuntu2 qemu-kvm 0.14.0+noroms-0ubuntu4.4 drbd8-utils 8.3.9-1ubuntu1 What I'd like to know is if this bug between KVM & RAID1 is known and whether it has been addressed in newer versions of the kernel and/or KVM. I'm on the verge of buying a hardware RAID card to resolve this and I'd rather not have to deal with that. Software RAID is so much nicer to manage. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
