I'm experimenting with booting root filesystem from
LVM volume inside the
raid (mdraid superblock 1.x) via
GRUB2. Also I'm using
From grub command line I can see my lvm volume (ls command) but I got kernel panic due to "unable to mount root fs". I saw a note in this article telling it's probably impossible to boot root fs from raid via UEFI, but I don't understand the reason why not.
Is it possible to boot linux with this configuration without the initramfs (which I don't want to use)?
