Description Bertrand 2017-06-28 12:44:15 EDT

Description of problem:


When volume backends were defined in the [DEFAULT] cinder.conf config
section, it did not make sense to have more than one AZ config setting.
Now that we have multibackend and we have deprecated the ability to
configure backends in DEFAULT, we can set AZs per backend section.

This previously required setting up a separate service using a different
cinder.conf to have more than one AZ. But since the vast majority of
backends are separate physical devices, there is no reason to restrict
the control plane service to be on separate nodes to support separate AZ
configurations.
