[Bug 1466150] Re: grub-install breaks when ESP is on raid

[Ben Stanley]

The way to make it work is to place the EFI on a separate GPT raided 
partition, outside the LVM PV. Which I forgot about when I wrote the idea 
earlier.

Title:
  grub-install breaks when ESP is on raid

Status in grub-installer package in Ubuntu:
  Triaged

Bug description:
  I run a server with mirrored (RAID1) disks using grub-efi.

  Root and /boot and /boot/grub are on mirrored partitions.

  I have EFI partitions on both disks but it is not possible to RAID1
  these as they are FAT32.  On an EFI system grub-install will only
  install to one of the EFI partitions and so after running install-grub
  you have to remember to copy the EFI file across.

  Could grub configuration and grub-install be amended to automatically
  install to multiple disks?

  Searching around there seem to be many people asking this question
  without any elegant solution.
