Public bug reported: I was using 10.04 Server LTS when I decided to do an upgrade.
I'm using fakeraid and my boot path is /dev/mapper/isw_ecdhgaacgh_Volume01 After running the "do-release-upgrade" and rebooting, the boot failed with an error and a busybox with "ALERT! /dev/mapper/isw_ecdhgaacgh_Volume01 does not exist". Somewhere along the upgrade process from 10.04 to 11 the actual root switched names from /dev/mapper/isw_ecdhgaacgh_Volume01 to /dev/mapper/isw_ecdhgaacgh_Volume0p1. I figured that out, when I did "ls /dev/mapper" in the busybox. So basically, my menu.lst still had the "01", but the new kernel was now attaching volumes to "0p1". Well, it wasn't that hard to fix. I rebooted the system with the old kernel (which was luckily still available in menu.lst), then changed the paths in /boot/grub/menu.lst and /etc/fstab from /dev/mapper/isw_ecdhgaacgh_Volume01 to /dev/mapper/isw_ecdhgaacgh_Volume0p1 and rebooted again. Got it fixed by hand, but still - this bug shouldn't be in the upgrade stream. ** Affects: dmraid (Ubuntu) Importance: Undecided Status: New ** Tags: boot dmraid kernel mapper -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/820810 Title: After upgrading from 10.04 system would not boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/820810/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
