I see what's going on. So ovn-controller on chassis-2 detects the failover and claims the cr-<gateway_port>. But ovn-controller on chassis-1 which has higher priority claims it back because according to it, BFD is fine. You can probably monitor the ovn-controller logs on both chassis, and you might notice claim/release logs. Or you can do "tail -f ovnsb_db.db" and see that there are constant updates to the cr-<gateway_port>. Having 3 chassis will not result in this split brain scenario which you have probably observed.
