This problem happens again after updating. The package which caused the problem is libc-bin (this package was installed between the previous successful boot and the first boot failure, other packages installed in the same update are applications and not system related packages). Hence I have reaffected this bug to libc-bin. Tried booting several times with same error message at boot giving up waiting for root devive /dev/mapper/sysvg-lvroot1
I was wrong about grub.cfg. It was unchanged between the reboots, so it could not be the culprit. However I managed to fix the problem, by booting into a liveCD, mounting and chrooting my system. Contrary to the previous time, I did nothing but backup some logs. I did not install, tweak any configuration or merge my lvm snapshot like last time. Then after a reboot, it was working fine. It seems that just the manual mounting I did for the chroot. I have no idea how this worked, but I would like to understand. ** Package changed: grub2 (Ubuntu) => glibc (Ubuntu) ** Summary changed: - boot fails with lvm root device in /dev/mapper not found after updates from proposed + boot fails with lvm root device in /dev/mapper not found after update of libc-bin -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1421877 Title: boot fails with lvm root device in /dev/mapper not found after update of libc-bin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1421877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
