Move PEs from one PV to another. You can't move a PV.

Unless you're booting off iSCSI or really, really love software RAID
(which btrfs also kindly simplifies), the only reason you need a
separate /boot is because we're slow at putting updated filesystem
support in grub because there's no need because we default to a separate
/boot. There's a certain amount of circularity there.
Also we need to have the initramfs on an unencrypted chunk of disk.

My experience with LVM is that any number of error states dump me into
an awkward recovery scenario. Again it's not an inherent problem with
the technology, more just that because nobody outside the enterprise
world really cares about LVM nobody has bothered making it easy for
non-sysadmins to handle this stuff.
