Ensuring the EFI partition is mirrored on an Ubuntu install with root on software RAID 1

Posted by crox on Sunday, May 4. 2025

I found a working procedure here:

- Make sure both EFI partitions are mounted from /etc/fstab, eg. using /boot/eficopy in addition to /boot/efi. (Both partitions need to have the proper partition type GUID, i.e. C12A7328-F81F-11D2-BA4B-00A0C93EC93B or "EFI System".)

- Run dpkg-reconfigure grub-efi-amd64 and include both partitions when prompted.
