[Bug 1327133] Re: RAID1 installation of grub: grub-install /dev/md127p2 failed

[Phillip Susi]

No, this is unrelated to that old report that was invalid anyhow.  I was
able to reproduce this with mdadm --create -e 1.0 -n 2 -l 1 /dev/md0
/dev/sda /dev/sdb, then going through the install, it tried to install
to a partition on the array.  Interestingly, when I omit the -e 1.0, it
tries to install to /dev/sda, as it should, but this fails since the
default 1.2 metadata format does not leave room for grub.

Bug description:
  How to reproduce:

  1) Boot Ubuntu 14.04 64bit live
  2) Open "disks"
  3) Select 2 Hard drives and create a RAID 1 (mine had 2x 3TB SATA)
  4) Once finished open Ubuntu installer
  6) Click next and select the default settings (Erase everithing and install Ubuntu)
  7) Once installation finshes in reports: grub-install /dev/md127p2 failed and propts you to select other partition. Which evere you select, the system will report that the installation is completed but once you reboot you will get boot disk failure, as if there is no Grub installation
