I have toyed with hybrid GPT in the past, in the hope to make an USB stick that was bootable in legacy mode, bootable in UEFI mode and usable as a regular USB stick (spoiler: it worked, until I tried it with Windows.) But it will not help for this issue. > The only issue, i have had a look at, was the problem to have a raid, > that is bootable no matter which one of the drives initially fails, a > problem, that can be solved by having at least 2 grub installs (on the > two mirrors). > > Certainly, there is a solution to your problem, even if might not > exactly fulfill your premises. I know of this solution. Unfortunately, that puts the partition table and EFI partition outside the RAID: if you have to add/replace a disk, you need to partition and reinstall GRUB, that makes a few more manipulations on top of syncing the RAID.
