Zone groups

Zone groups define the geographic location of one or more Ceph Object Gateway instances within one or more zones.

The Ceph Object Gateway supports multi-site deployments and a global namespace by using the notion of zone groups.

Note: Zone groups were previously referred to as regions.

Configuring zone groups differs from typical configuration procedures, because not all of the settings end up in a Ceph configuration file. You can list zone groups, get a zone group configuration, and set a zone group configuration.

Note: The radosgw-admin zonegroup operations can be performed on any node within the realm, because the step of updating the period propagates the changes throughout the cluster. However, radosgw-admin zone operations MUST be performed on a host within the zone.
