By any chance, did you an upgrade from Essex to Folsom release without
doing migration steps?

Another idea: Did you install OpenStack with openstack-demo-install?
Cinder/nova-volume requires a Volume group named cinder-volume
You might also want to stop nova-volume service and start
cinder-volumes/nova-volumes. If you installed OpenStack following the
TestDay page, cinder/nova-volume service is not started by default,
and also a volume group is not created persistantly.

Dashboard in it's current version requires a volume service enabled
(and running/answering to requests!)

An output of openstack-status and from keystone service-list will help
us here.
