I *think* the grub volume itself has to be plain, no lvm, mdadm etc. All |
20 |
the stuff for that is in the initramfs, so grub loads the initramfs, |
21 |
starts the kernel, the kernel starts pid 1 which can now start mdadm, |
22 |
lvm etc, and then it can pivot root onto the proper root filesystem. |
