[Bug 1170584] Re: installer unresponsive after attempting grub installation on partitionable raid

[Tuomas Heino]

Retried after resync'ing to most recent live image.

When installer got to the

Executing 'grub-install /dev/vda' failed.
This is a fatal error.

Did not press ok this time, but ran the following:

ubuntu at ubuntu:~$ sudo chroot /target apt-get install mdadm
ubuntu at ubuntu:~$ sudo chroot /target grub-install --no-floppy /dev/vda
/usr/sbin/grub-bios-setup: error: unable to identify a filesystem in hostdisk//dev/vda; safety check can't be performed.
ubuntu at ubuntu:~$ sudo chroot /target grub-install --no-floppy /dev/vdb
/usr/sbin/grub-bios-setup: error: unable to identify a filesystem in hostdisk//dev/vdb; safety check can't be performed.
ubuntu at ubuntu:~$ sudo chroot /target grub-install /dev/vdc
/usr/sbin/grub-bios-setup: error: unable to identify a filesystem in hostdisk//dev/vdc; safety check can't be performed.

After that, clicked ok on that "fatal error" message mentioned above.

Result is a Bootloader install failed dialog with rather peculiar UI behaviour:
1. mouse icon is a spinner everywhere else except on the text input dialog
2. text input dialog/dropdown does not allow keyboard input, but copy/paste with mouse works as well as opening the dropdown with mouse
3. choosing /dev/md_d2 from list will result in ok button being dimmed without explanation why, even if you choose "cancel the installation" after that

After that, chose /dev/vdb this time and pressed ok. That resulted in rather misleading situation:
Installation Complete dialog with continue testing / restart now -buttons was overlaid on top of Unable to install GRUB in /dev/vdb dialog, hiding that error entirely underneath.

  partitionable raid

Status in “grub-installer” package in Ubuntu:
  New

Bug description:
  1. boot to livecd (desktop)
  2. $ sudo apt-get install mdadm
  3. $ sudo mdadm -C /dev/md_d2 -l 1 -n 1 -f -x 2 /dev/vd[abc]
  4. run installer, tell it to use entire md_d2 disk for lvm

  Executing 'grub-install /dev/vda' failed.
  This is a fatal error.

  Somewhat related to bug #1058129 and bug #1068137.

  After looking around a bit and possibly mounting things that were not mounted:
  $ sudo grub-install --root-directory=/target /dev/md_d2
  Installation finished. No error reported.
