Upgraded from maverick to natty and had a similar issue: - bootfs is ext3, rootfs ext4 - both are logical volumes on top of raid1 - did snapshots of root & boot before upgrade and it worked for the first reboot
After that, grub2 just booted the menu entry, did a lot of hdd access and stoped w/o any errors or messages. I could get the kernel & initramfs loaded by striping the menu entry down to: insmod part_msdos, raid, lvm, ext2 root (vg-device) kernel... initramfs... but mounting the rootfs failed within initramfs and it dropped to a shell. mounting the logical volume (roots) within that shell worked. changing the filesystem UUIDs within my snapshots of rootfs & boot didnt change anything. after deleting both snapshots, grub2 & initramfs booted w/o any error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/563895 Title: grub2 fails to boot or install when an LVM snapshot exists -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
