horizon can't create a volume in "Any availability zone" when following the documentation and having storage_hosts different than storage-infra_hosts

[Jean-Philippe Evrard]

If you follow the documentation, you'll define in openstack_user_config.yml the "cinder_default_availability_zone" and cinder_storage_availability_zone.

If you have your storage-infra hosts (where is your cinder scheduler) on the same hosts as your storage hosts, you'll be able to create your volume with horizon with the option to create a volume in "Any availability zone".

However, when storage-infra hosts and storage hosts are different, the formers don't get the "cinder_*_availability_zone" variables. Therefore, when horizon will try to create in "any availability zone", it will try to create with the default, which is unset (and defaults to nova). The volume creation then fails.

The solution is to adapt the documentation, and mention that defaults availability zone must be created in user_variables, while overrides per hosts should be in the openstack_user_config.

    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.
