The EFI system partition must not be on LVM or mdadm RAID. The UEFI needs to be able to read it. That means it needs to have EF00 partition type and FAT file system.
That's weird. I just confirmed, yes, my system is EFI: [root@jack ~]# ls /sys/firmware/efi config_table esrt fw_vendor runtime systab efivars fw_platform_size mok-variables runtime-map … and my /boot/efi is on mdraid. [root@jack ~]# mount | grep /dev/md /dev/md127 on / type ext4 (rw,relatime,seclabel) /dev/md125 on /boot type ext4 (rw,relatime,seclabel)/dev/md123 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=winnt,errors=remount- ro)
/dev/md124 on /home type ext4 (rw,relatime,seclabel)The trick is to create a version 1.0 RAID volume, where the RAID superblock is at the end of the raw partition, and RAID-unaware bits just see an ordinary partition, instead of the default version 1.1 RAID where the RAID stuff is at the beginning of the partition.
