** Description changed:
+ [Impact]
+ Users installing on ppc64el with RAID enabled, doing manual or guided
partitioning are unable to complete the installation because the multiple
passes of partitioning required to apply the initial partitions on disk (PReP
partitions and all) and the next set of partitions on RAID or LVM cause the
initial PReP flags to be lost.
+
+ [Test case]
+ 1) Start installation on a ppc64el system with two or more disks.
+ 2) Use manual partitioning to add a PReP partition on one of the disks. It
should have a size of 8MB, at the beginning of the disk. It can be followed by
free space or a single partition to be used as space for RAID.
+ 3) Create a RAID volume, using RAID1 (2 partitions, 0 spaces), add the RAID
partition previously created and the free space from another disk.
+ 4) End partitioning, confirming everything.
+
+ The installation should complete successfully.
+
+ [Regression potential]
+ This is limited to the handling of PReP partitions, so only applies to
ppc64el systems. Possible regressions may be failure to allow a valid setup of
partitions while preparing the install on ppc64el, or failure of the
installation on an invalid (but not immediately detected) partition setup, at
the point where grub-installer will try to install the bootloader on the system.

I am trying to install Ubuntu14.04 on the firestone machine on a RAID1 array,
configured with software raid.
Installation goes on smoothly till its reaches grub loader and fails. Below I
have pasted the error.

the PReP partition.
Aug 19 11:08:01 grub-installer: error: Running 'grub-install --force
"/dev/md0p1"' failed.
and the "error:" message 'failed to copy Grub to the PReP partition.' is
not generated by the grub-installer script itself [1], so probably
coming down from grub2.
I'd suggest to either involve our grub2 guy (not sure if available), or
mirroring to Canonical.
