Jean-Philippe Evrard de4ca4c318 More complete explanation of availability zones 
If you follow the documentation, you'll define
the "cinder_default_availability_zone" in your
openstack_user_config

If you aren't in AIO this is gonna cause you
issues (horizon fails to create volume in
"Any availability zone")

This clears the things up.

Availability zones

Multiple availability zones can be created to manage Block Storage storage hosts. Edit the /etc/openstack_deploy/openstack_user_config.yml and /etc/openstack_deploy/user_variables.yml files to set up availability zones.

  1. For each cinder storage host, configure the availability zone under the container_vars stanza:

    cinder_storage_availability_zone: CINDERAZ

    Replace ``CINDERAZ`` with a suitable name. For example ``cinderAZ_2``

  2. If more than one availability zone is created, configure the default availability zone for all the hosts by creating a cinder_default_availability_zone in your /etc/openstack_deploy/user_variables.yml

    cinder_default_availability_zone: CINDERAZ_DEFAULT

    Replace ``CINDERAZ_DEFAULT`` with a suitable name. For example, ``cinderAZ_1``. The default availability zone should be the same for all cinder hosts.

    If the cinder_default_availability_zone is not defined, the default variable will be used (nova). This could make horizon's volume creation fail.
