The northbound and southbound databases are independent. There is no need for them to have the same cluster nodes. They don't even necessarily both have to be clustered databases. There isn't any reason that ovn-northd needs to connect to northbound and southbound databases simultaneously. In fact, the idea of simultaneity in a distributed system is problematic. ovn-northd only locks the connection to the southbound database. _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
