Cinder's failover support allows us to test a disaster recovery configuration by initiating a failover operation and verifying that the driver correctly passes control of the replicated volumes to a secondary site. With the recent merge of the RBD replication in the Cinder driver, this failover is now supported for ceph-backed cinder deployments. Cinder also provides a failback operation to allow an administrator to undo a previous failover. This operation is not completely implemented and work is needed before it is complete.
Cinder replication is not a supported RHOS feature, so closing this one out as the work here was delivered upstream. If and when Cinder replication needs to get planned as a RHOSP feature, a different BZ will be opened.
