[Bug 743136] Re: grub2 fails to install on md0

[Youssef Eldakar]

Is this supposed to be fixed in Natty? I am using a standard partman-
auto-raid/recipe in a preseeded Natty install and am running into the
same issue:

d-i partman-auto-raid/recipe string                  \
                1 2 0 jfs  /                         \
                        /dev/sda5#/dev/sdc5                     \
                        .                            \
                0 4 0 swap -                         \
                        /dev/sda6#/dev/sdb6#/dev/sdc6#/dev/sdd6 \
                        .                            \
                1 2 0 jfs  /usr                      \
                        /dev/sda7#/dev/sdc7                     \
                        .                            \
                5 4 0 jfs  /var                      \
                        /dev/sda8#/dev/sdb8#/dev/sdc8#/dev/sdd8 \
                        .                            \
                0 4 0 jfs  /tmp                      \
                        /dev/sda9#/dev/sdb9#/dev/sdc9#/dev/sdd9 \
                        .                            \
                5 4 0 jfs  /srv                      \
                        /dev/sda1#/dev/sdb1#/dev/sdc1#/dev/sdd1 \
                        .

Symlinking /dev/md0 to /dev/md/0 before running the grub-install seems
to get it to succeed.

I am sorry if this is not the appropriate place for this comment.

Title:
  grub2 fails to install on md0

Status in “grub2” package in Ubuntu:

Status in “grub2” source package in Natty:
  Fix Released

Bug description:
  Binary package hint: grub-pc

  During installation of Natty I get the error below, this error did not occur in Maverick.
  /dev/md0 is a raid0 device.
  I have tried the filesystems ext2 and ext4 for /boot but both result in the same error.
