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.

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``
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.
