If I was you, I would boot the SystemRescueCD, mount your /home partition. Then rsync the data to someplace else - another system on your network? If your root partition is also xfs, then mount/rsync that data as well. Then remove, expand or recreate your LVM based volumes, mkfs and rsync the data back. I'm assuming you have a /boot partition that is not LVM based so no need to reinstall grub. Then reboot. Side note: my solution doesn't require you to set up a chroot, just mount the partition in order to back up the data on the filesystem. I like Gentoo's LVM documentation[0] Hope this helps.
