That fails in exactly the same way...
It is clear that the lvm subsystem is not being set up properly; both
partitions on sda are seen, but neither can be used as a rootfs, because
the rootfs is in a LV on one of them.
The old grub-install used to do the same thing - it would only include lvm
in the initrd if the rootfs was on a LV. If rootfs was not on a LV, but
one of the other necessary filesystems were, you'd get no lvm support in
your initrd, and the boot would then fail.
But with grub2, I'm a bit lost as to how to fix things. Even putting an
explicit "insmod lvm" into grub.cfg doesn't seem to get things going...
