Bug Description

Commit https://git.openstack.org/cgit/openstack/nova/commit/?id=6060888b58db42eea826939852838f9e1c204d2c changed Cinder behavior to always create a volume in a Cinder availability zone with the same name as the Nova availability zone, if a specific AZ is requested. This is problematic for us, as we use Ceph for backing storage with Cinder and do not rely on Cinder to manage our failure domains (other people are also experiencing this problem, e.g., http://osdir.com/ml/openstack-dev/2015-08/msg00609.html).

I have a patch with test cases against master and will be submitting it for review shortly.

    Adds allow_availability_zone_fallback option to Cinder

    This change adds allow_availability_zone_fallback, which allows Cinder
    to fall back to an already configured availability zone if the
    requested availability zone is unavailable.
