I didn't know this guide from HPE. What I'm not sure is how well it is supported now for newer distributions like EL9. I could be wrong but I think EL9 already supports setting this up out of the box without any additional fiddling. In my case years ago with EL7 I simply put /boot/efi on a partition on disk 0 and another one on disk 1, like so: /dev/nvme0n1p1 200M 12M 189M 6% /boot/efi /dev/nvme1n1p1 200M 12M 189M 6% /boot/efi.backup To keep the filesystems in sync I've added a hook to our package update mechanism which simply calls this bash function: EFISRC="/boot/efi" EFIDEST="${EFISRC}.backup" efisync() { if [ -d "${EFISRC}/EFI" -a -d "${EFIDEST}/EFI" ]; then rsync --archive --delete --verbose "${EFISRC}/EFI" "${EFIDEST}/" fi } If I had to install this today I'd like to put it on RAID as discussed.
