Public bug reported: Disks earlier prepared using mdadm(8) and lvm2; /boot is an md(4) mirror, while /, /home and /var are lvm2 logical volumes. In the live environment, I installed mdadm and lvm2 using apt-get, and started the arrays (which also configured the volume group).
Then I started the Kubuntu installer, selected manual partitioning, and set up the three LVs to be formatted as ext4, and md127 (/boot) to be formatted as ext3. I chose also chose /dev/md127 as the location to install grub. Towards the end of the installation, an error occurred "grub-install /dev/sda failed - this is fatal". So it looks like my choice isn't preserved and passed through to grub-install. In addition, manually mounting the new root & boot filesystems and running "grub-install --boot-directory=/mnt/boot /dev/md127" also fails, with a segfault in the underlying command "/usr/sbin/grub-setup --directory=/mnt/boot/grub --device-map=/mnt/boot/grub/device.map /dev/md127" :-( ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: ubiquity 2.10.16 [modified: lib/partman/automatically_partition/question] ProcVersionSignature: Ubuntu 3.2.0-23.36-generic 3.2.14 Uname: Linux 3.2.0-23-generic x86_64 ApportVersion: 2.0.1-0ubuntu5 Architecture: amd64 CasperVersion: 1.315 Date: Wed Jan 23 00:42:05 2013 InstallCmdLine: file=/cdrom/preseed/kubuntu.seed boot=casper maybe-ubiquity initrd=/casper/initrd.lz quiet splash -- keyboard-configuration/layoutcode=gb LiveMediaBuild: Kubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120423) ProcEnviron: LANGUAGE= TERM=xterm LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: grub-installer UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: grub-installer (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug precise ubiquity-2.10.16 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1103256 Title: Kubuntu installer failed at grub-install (on wrong device) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1103256/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
