On my disk I have LVM configured as such:
- One Volume Group "vg1", containing
- One Logical Volume "lv1", containing a LUKS encrypted partition which is the root of a Debian Linux installation
- One Logical Volume "00" containing another LUKS encrypted partition which is the root of a Qubes OS installation
I want the system to boot into Qubes; in other words, I need to unlock vg1/00 and then mount it as the root device.
The problem is that Grub only asks me to unlock logical volume "lv1". I can't make Grub ask to unlock the "00" logical volume no matter the kernel boot options.
Editing grub's command line at boot I can see
root=/dev/mapper/luks-<UUID> as well as
rd.lvm.lv=luks.<UUID>. The UUID matches the correct logical volume.
How can I make sure that grub actually uses the
rd.lvm boot options?
