Subject: grub-efi-amd64: Update-grub ignores multiple EFI boot partitions - stops boot after loss of first EFI disk
Date: Fri, 17 Oct 2014 18:53:17 +0100
Package: grub-efi-amd64
Version: 2.02~beta2-14
Severity: normal
Tags: d-i

Dear Maintainer,

update-grub installs only onto the first EFI boot partition it finds. Other partitions are ignored.

My system has 4 drives configured with 3 RAID sets. The first two drives are a single RAID set under Intel RST used for Win 7.1 Pro. The drives are configured:

Drive 1 & 2 under Intel RST RAID 1 (/dev/md126p):

100MB EFI Boot
128MB MS Reserved
Rest of drive partitioned for windows drives.

Disk 3 /dev/sdc
sdc1 - 250M - EFI Boot
sdc2 - 750M - RAID 1 (/dev/md0) for /boot on ext4
sdc3 - rest of drive - RAID 1 (/dev/md1) for LVM

Disk 4 /dev/sdd
sdd1 - 250M - EFI Boot
sdd2 - 750M - RAID 1 (/dev/md0) for /boot on ext4
sdd3 - rest of drive - RAID 1 (/dev/md1) for LVM

The installer only configures the EFI boot on the raid set made up of disks 1 or 2. So if disk 1 fails or is removed the system will continue to boot. However, loss or removal of both disks 1 & 2 should leave the system operable as a multi-os boot system has meant the Debian systems are (and should be) completely unaffected by the removal/failure of disks 1 & 2. However, the current situation renders the system unbootable.

For reliable raid the installer should ALSO populate the EFI Boot partitions on disks 3 & 4. Thus ensuring that the o/s is visible to the BIOS and will actually boot. 

There is a manual work around for this which I shall add to this report for those that are interested.

[Message part 1 (text/plain, inline)]
It looks like Ubuntu added multi ESP support here
https://git.launchpad.net/ubuntu/+source/grub2/commit/?id=05a57249548c247c14231ef15348a4ee27217607

It may be something that could be brought to Debian fairly easily.

Subject: Hope support for multiple ESPs can be upstreamed from Ubuntu -> Debian
Date: Wed, 11 Aug 2021 10:38:45 -0400
I ran into this yesterday while installing Bullseye on a UEFI system 
with multiple drives and ESPs. Here are a couple of links describing how 
Ubuntu's multi-ESP works:

https://unix.stackexchange.com/questions/621942/mirroring-efi-system-partition-esp-on-ubuntu

https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1466150

I tried running
dpkg-reconfigure grub-efi-amd64
on my multi-ESP Bullseye system in the hope that the Ubuntu support may 
have been upstreamed, but alas it has not yet happened. I'll ask on 
Ubuntu list as well whether someone is working on upstreaming.

I've attempted the same with no success, I do not believe this has been integrated, at least as of Debian 11.5. I do hope this is upstreamed at some point, as it's a big win for those setting up systems without hardware raid but require the ability to survive OS disk failures and still boot without a lot of manual setup.
