Hi All, I have testing OpenStack (Queens Version) with OVN and works, but when I want to cluster the ovsdb-server, OpenStack stuck to create neutron object. based on my discussion in openvswitch mailing list ( https://mail.openvswitch.org/pipermail/ovs-discuss/2019-August/049175.html), my ovsdb-server clustering databases are working. Is networking-ovn support to connect to multiple ovsdb-server? something like this in ml2_conf.ini [ovn] ovn_nb_connection = tcp:10.101.101.100:6641,tcp:10.101.101.101:6641,tcp: 10.101.101.102:6641 ovn_sb_connection = tcp:10.101.101.100:6642,tcp:10.101.101.101:6642,tcp: 10.101.101.102:6642 networking-ovn-metadata-agent.ini [ovn] ovn_sb_connection = tcp:10.101.101.100:6642,tcp:10.101.101.101:6642,tcp: 10.101.101.102:6642 Below is the full step to create ovsdb-server and neutron services. - step 1: bootstrapping ovsdb-server cluster : http://paste.openstack.org/show/766812/ - step 2: creating neutron service in controller : http://paste.openstack.org/show/766464/ - step 3: creating neutron service in compute : http://paste.openstack.org/show/766465/ But when I try to create neutron resource, Its always hang (only neutron resource). This is the full logs of all nodes, contain: http://paste.openstack.org/show/766461/ - all openvswitch logs - port (via netstat) - step bootstraping ovsdb-server Neutron logs in controller0: paste.openstack.org/show/766462/ Is networking-ovn support to connect to multiple ovsdb-server?
