Availability zones

Multiple availability zones can be created to manage Block Storage storage hosts. Edit the /etc/openstack_deploy/openstack_user_config.yml file 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 scheduling volume creation:

    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 storage hosts.

    If the cinder_default_availability_zone is not defined, the default variable will be used.
