If not, you might want to consider making a new LV (perhaps shrinking one of your other partitions and reclaiming some of that 200GB free space) for root. You could then boot into a LiveCD, rsync from the old root partition to the new partition and then update bootloader, fstab etc. Et Voila, you're booting from root on LVM. Next time root gets full, add a few extents to it. > > 2.

You might be able to do this online by creating a PV on the SSD, add it to your VG and then use "pvmove" to migrate LVs between the disks.
