[Bug 1466150] Re: Feature request: For EFI system grub-install should be able to install to multiple disks

[Phillip Susi]

Choice of filesystem has nothing to do with raid.  You can put any FAT32
partition, including the ESP, on a raid1 if you want.  You just need to
make sure to use md format 0.9 or 1.0 instead of 1.1 or 1.2 so the
firmware will still recognize it.

Title:
  Feature request: For EFI system grub-install should be able to install
  to multiple disks

Status in grub2 package in Ubuntu:
  Invalid

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.
