[Bug 1315344] Re: Grub install failed on disks with software RAID

[Kevin Lyda]

Doh! In my case the issue was that I had replaced one of the disks on
the server. In the process the server had decided it was going to boot
from disk #3... Changed that and it all seems to have worked. Trying a
full RAID install now.

Title:
  Grub install failed on disks with software RAID

Status in grub-installer package in Ubuntu:
  Incomplete

Bug description:
  I've got two 2TB drives set up with identical partitions, which are combined into RAID1 arrays (five mirrors across the two disks).
  On a free RAID1 I've installed Trusty 64bit from the Desktop installer ("try Ubuntu" first, install mdadm, run mdadm --assemble --scan, then start installer). I then wanted grub to be installed onto /dev/sda and /dev/sdb, but both fail.
