[Bug 1059471] Re: 2.41 fails to mount root partition
it would seem that mountall is likely the difference between pretty green dots at [1] (ubuntu-quantal-daily-i386-server-20121125) and the evil red dots at [2] (ubuntu-quantal-daily-i386-server-20121128) . The difference in manifests of those 2 builds are http://paste.ubuntu.com/1408166/ . The likely suspect there is mountall. Note, this is a race condition, and seems to now be the same issue that we were seeing on raring for quite some time as bug 1078926. I can provide access to reproduce system or console --verbose output. One possibly related issue is that it seems that loss of output to /dev/console is now increased in likelyhood. -- [1] https://jenkins.qa.ubuntu.com/view/ec2%20AMI%20Testing/view/Overview/job/quantal-server-ec2-daily/153/ [2] https://jenkins.qa.ubuntu.com/view/ec2%20AMI%20Testing/view/Overview/job/quantal-server-ec2-daily/154/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1059471 Title: 2.41 fails to mount root partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/1059471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1059471] Re: 2.41 fails to mount root partition
** Description changed: + [Impact] + A change introduced in mountall in quantal can cause boot-time hangs for some users when a filesystem is listed in /etc/fstab with a non-canonicalized mount point. This is a regression vs. previous releases. + + [Test case] + 1. Create a directory, /mnt/realmount + 2. Make /mnt/linkmount a symlink to /mnt/realmount + 3. Add the following entry to /etc/fstab, immediately after the root filesystem: +overlay /mnt/linkmount tmpfs defaults 0 0 + (order here matters because this is a virtual filesystem, and mountall creates implicit dependencies for virtual filesystems based on /etc/fstab ordering) + 4. Install plymouth to the initramfs by running: 'echo FRAMEBUFFER=yes > /etc/initramfs-tools/conf.d/lp1059471; update-initramfs -u'. (Otherwise, the boot will hang before plymouth splash has started.) + 5. Reboot. Confirm that the system hangs on boot with a message about /mnt/linkmount not being mounted. + 6. Press 'S' to skip this filesystem and finish booting. + 7. Install mountall 2.42 from proposed. + 8. Reboot. Confirm that the system boots all the way up without hanging. + 9. Clean up by running 'rm -f /etc/initramfs-tools/conf.d/lp1059471; update-initramfs -u'. + + [Regression potential] + The mountall code is very complicated, with little test coverage and no integration testing. I believe the code is now correct, but the risk of a regression in an unrelated boot configuration is non-negligible. + When booting with 2.41, I get a message "The disk drive for / is not ready yet or not present" but when I drop into a shell for manual recovery, / curiously /is/ mounted. Downgrading mountall to 2.40 allows me to boot again. Let me know if you need any more information.
