The hosted-engine configured hosts communicate via a whiteboard wrote on the hosted-engine storage domain so, if the storage devices on the two sites are in sync (it requires latency < 7ms), all the hosted-engine host can also see the status on the other site and eventually take over. The volume lease is there to enforce, at storage level, that only one host at a time is able to run the engine VM (regardless of the site where is it since also the lock is in sync). > > > > > > Did you read > > > https://ovirt.org/documentation/disaster-recovery-guide/active_active_ove. > .. > > ? > Yes, and it's only say "Configure all virtual machines that need to > failover as highly available, and ensure that the virtual machine has a > lease on the target storage domain." > But the manager, It's configured for HA storage by default?.
