When deploying a single backend, the tripleo template takes care of
generating the nfs shares file (actually, puppet-cinder generates the file,
but it's triggered by tripleo). But when you use the custom backend method
that Emilien pointed you to use, then you are responsible for supplying all
the pieces for the backend(s) to function correctly. This means you will
need to generate the nfs shares file on the host (controller), and then
bind mount the file using CinderVolumeOptVolumes so that the shares file on
the host is visible to the cinder-volume process running in a container.
I'm wondering if it's possible to define a second backend by creating

Sorry, this won't work. TripleO will trying to deploy two completely
separate instances of the cinder-volume service, but the two deployments
will step all over each other. There has been a long standing goal of
enhancing tripleo so that it can deploy multiple instances of a cinder
backend, but it's a complex task that will require non-trivial changes to
