[Bug 1023064] Re: Ubuntu installer crashed installing bootloader on btrfs+hw_raid5

[Damiön la Bagh]

btrfs is designed to replace the partition table, the partitions, the software raid controller and the filesystem.
There is no place to put a 64mb bios_grub partition as the disk becomes pure btrfs.

This is definitly not solved. When using a partition table-less btrfs
install, which is the way btrfs is designed to be used, grub should be
creating it's bootloader in /@/boot but instead the installer is
crashing.

Title:
  Ubuntu installer crashed installing bootloader on btrfs+hw_raid5

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

Bug description:
  Distributor ID:	Ubuntu
  Description:	Ubuntu 12.04 LTS
  Release:	12.04
  Codename:	precise
  LiveUSB 64-bit

  ubuntu at ubuntu:~$ apt-cache policy grub-installer
  N: Unable to locate package grub-installer

  Setup:
  Hardware Raid controller 768000MB RAID5 over 4 disks   mount point /home fstype btrfs
  Single disk (outside the raid) 320000MB partition1 mount / fstype btrfs
              10000 partition0 mount /swap fstype linux-swap                              

  Expected: grub-installer writes the booth loader to device /dev/sdc
  ubuntu installs, and we can use the computer

  What really happened:
  during the install of Ubuntu when the grub-installer went to write out grub the installer crashed.

  Will have to try again with a seperate /boot partition outside the
  btrfs file system to see if I can get it to start that way.
