That maybe the wrong answer as the database (both cinder and the older
nova leavings) has a provider_location that implies the "right"
logical volume name:

+--------------------------------------+--------+-----------------------------------------------------------------------------------------------+
| id                                   | ec2_id | provider_location

so I'm also open to suggestions on the "right" resolution to this.
Should I rename the logical volume sand update the provider_location
or should I make the  /var/lib/cinder/volumes/* files match what is in
the database and LVM (and if I do the latter will something come along
and undo that)?
