[Bug 1327133] Re: grub-install defaults to partition on whole disk raid array rather than underlying disk or whole raid array

[Steve Langasek]

Closing this bug 'wontfix'.  Full-disk software RAID is incompatible
with UEFI which almost all amd64 systems include nowadays.  Ubuntu 14.04
LTS, while still supported, is not undergoing any further development
work, only security fixes; and no further install media will be issued.
I do not know if this bug is fixed in later releases of Ubuntu, but
ubiquity which embeds grub-installer is also not undergoing further
active development, we are in the process of replacing it with a
frontend to subiquity.  But subiquity will also not want you to use
full-disk RAID, again because it's incompatible with UEFI.

** Changed in: grub-installer (Ubuntu)
       Status: Triaged => Won't Fix

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
