[Bug 833783] Re: boot failure: can't open /root/dev/console: no such file
well, after upgrades to the nova installation that I was using, we are no longer running our images backed by a qcow2 compressed image. Instead, the root disk is a qcow2 disk backed by a raw disk image. This obviously changes timing conditions as disk reads no longer take cpu to do decompression. I've now run 240 instances, and not been able to reproduce this with the modified ramdisk to catch the output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/833783 Title: boot failure: can't open /root/dev/console: no such file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/833783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 833783] Re: boot failure: can't open /root/dev/console: no such file
over the weekend i ran 521 instances of an image with patch from comment 12 in the initramfs, and 339 instances of a 'control' image. I ran this against a Canonical internal developer cloud. Unfortunately, I failed to hit this race in any of them. However, today, I just ran 2 instances of beta2 against the CanoniStack, and hit it on both. Possible reasons for the differing results: a.) developer cloud is just different hardware (cpu/disk) b.) develoepr cloud was running more recent nova snapshot I really dont put any stock in 'b' though, as i really think this is just a timing race in the kvm guest. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/833783 Title: boot failure: can't open /root/dev/console: no such file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/833783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

OK. So I ran 57 instances of the control ramdisk on my cloud that was reproducing earlier. 2 of the 57 hit the failure. I ran [successfully] of the modified ramdisk, and 1 had a failure. So it seems just based on that, that we're not significantly more or less likely to hit the failure with the modified image. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/833783 Title: boot failure: can't open /root/dev/console: no such file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/833783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
