Description Dan Williams 2021-09-20 15:41:59 UTC 
+++ This bug was initially created as a clone of Bug #1999704 +++

When connecting to a clustered ovsdb, ovn-nbctl always connects to the leader. However, ebay/go-ovn doesn't do this.

We should duplicate that behavior.

In order to do it, you need to check the special _Server database that includes information as to whether or not the node is a leader.

You can see a similar implementation for ovn-org/libovsdb in https://github.com/ovn-org/libovsdb/pull/221

Fixed upstream in ovnkube in https://github.com/ovn-org/ovn-kubernetes/pull/2464

Will be pulled into 4.10 when Tim does the next merge to downstream.

---------------

Since 4.9 and earlier use ebay/go-ovn and ebay/libovsdb, they need this support too. The work is done but needs upstreaming.
