Title:
  grub-install doesn't include raid5rec.mod

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I just did a fresh install of Ubuntu 14.04.2 using the official
  install medium onto my NAS. My NAS contains three drives which I run
  in a RAID5 configuration with LVM on top. I setup each drive to have a
  128MB EFI partition which stores grubx64.efi and put the rest of the
  drive under the RAID5+LVM configuration. The Ubuntu 14.04.2 and 15.04
  installs were happy to let me do that however when I try to boot into
  the freshly installed system the GRUB command prompt came up.

  While I was able to see the LVM partitions using ls I couldn't access
  them because I needed raid5rec.mod. I booted into a live CD and used
  grub-mkimage to create a grubx64.efi image which had raid5rec.mod, and
  all the other modules I needed to boot, embedded into grubx64.efi.

  Possible resolutions
  1. Store all grub modules on the EFI partition
  2. Modify grub-install to create grubx64.efi with all block/file system modules embedded into the image needed to access the partition which contains the grub modules
