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

[Jack Ostroff]

I'm having the same problem with a new Gentoo install, but with a twist.
I am using lvm2 with a vg of two whole disk pvs and raid1 lvs for /,
/boot, and /boot/efi.  Since I'm not using mdadm, the script in comment
#18 doesn't work for me, and I'm not able to modify it for my case,
although I try a bit more.

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.
