OK so the system GRUB is running in doesn't use LVM at all, apparently.

root=/dev/sdb6 is incorrect, it should use UUID for this by default.
All Fedora 16 entries are like this.

OK...

What the hell? Every Fedora 20 entry says VolGrpSys2-root in the
description, but the kernel parameter line uses VolGrpSys0-root. This
is why I hate multibooting and find it fundamentally flawed and
perilous. Better to use VMs.
Anyway, you might get more information by editing
/etc/grub.d/30_os-prober and adding to the top:
set -v
set -x
And then rerun 'bash -x grub2-mkconfig'. The output will likely be a
lot longer. This very well could be a bug.
