Folks, I have 3 controller nodes and am trying to setup clustering for OVN deployment, but lack enough documentation and have some issues and questions regarding it. I found this document but again its little confusing and very old - https://mail.openvswitch.org/pipermail/ovs-discuss/2018-March/046470.html # controller 1 /usr/share/ovn/scripts/ovn-ctl --db-nb-addr=172.30.40.93 \ --db-nb-create-insecure-remote=yes \ --db-sb-addr=172.30.40.93 \ --db-sb-create-insecure-remote=yes \ --db-nb-cluster-local-addr=172.30.40.93 \ --db-sb-cluster-local-addr=172.30.40.93 \ --ovn-northd-nb-db=tcp:172.30.40.93:6641,tcp:172.30.40.25:6641,tcp:172.30.40.177:6641 \ --ovn-northd-sb-db=tcp:172.30.40.93:6642,tcp:172.30.40.25:6642,tcp:172.30.40.177:6642 \ start_northd # controller 2 /usr/share/ovn/scripts/ovn-ctl --db-nb-addr=172.30.40.25 \ --db-nb-create-insecure-remote=yes \ --db-sb-addr=172.30.40.25 \ --db-sb-create-insecure-remote=yes \ --db-nb-cluster-local-addr=172.30.40.25 \ --db-sb-cluster-local-addr=172.30.40.25 \ --db-nb-cluster-remote-addr=172.30.40.93 \ --db-sb-cluster-remote-addr=172.30.40.93 \ --ovn-northd-nb-db=tcp:172.30.40.93:6641,tcp:172.30.40.25:6641,tcp:172.30.40.177:6641 \ --ovn-northd-sb-db=tcp:172.30.40.93:6642,tcp:172.30.40.25:6642,tcp:172.30.40.177:6642 \ start_northd # controller 3 /usr/share/ovn/scripts/ovn-ctl --db-nb-addr=172.30.40.177 \ --db-nb-create-insecure-remote=yes \ --db-nb-cluster-local-addr=172.30.40.177 \ --db-sb-addr=172.30.40.177 \ --db-sb-create-insecure-remote=yes \ --db-sb-cluster-local-addr=172.30.40.177 \ --db-nb-cluster-remote-addr=172.30.40.93 \ --db-sb-cluster-remote-addr=172.30.40.93 \ --ovn-northd-nb-db=tcp:172.30.40.93:6641,tcp:172.30.40.25:6641,tcp:172.30.40.177:6641 \ --ovn-northd-sb-db=tcp:172.30.40.93:6642,tcp:172.30.40.25:6642,tcp:172.30.40.177:6642 \ start_northd ## Validation steps controller-2# export\ remote="tcp:172.30.40.93:6641,tcp:172.30.40.25:6641,tcp:172.30.40.177:6641" controller-2# ovn-nbctl --db=$remote show controller-2# In the above command i am seeing output only when it hit controller-1 node, but for node-2 and note-3 giving me empty output that means data replication doesn't work. what is the command to verify synchronization working between all 3 nodes? Do I need to restart any other services?
