Hello I known why this error appears (in my case at least), if you just delete partition information and then recreate new ones for lvm2, it might happen that the metadata of the deleted lvm2 partitions is still present. The easiest way to correct this errors is to wipe out the old metadata definitions. Use hexedit and zero those sectorts from your devices, but this is very dangerous... You should ask lvm2 team to help you. Grub2 cannot fix this, but a work around could be written.
