Ok this was faster than even considering looking for a stick...

# The volume group to use for docker storage. Defaults to the

So yeah, this will take some adjustment because you really don't want
it taking up free extents in this VG. Create a new VG, move a specific
amount of extents, change the .conf file to explicitly specify the VG
to use, and then docker-storage-setup can safely run.
