Interesting...
with this configuration on gateway (chassis) node,
========
external_ids : {ovn-bridge-mappings="physnet1:br-ex",
ovn-cms-options=enable-chassis-as-gw, ovn-encap-ip="10.6.30.91",
ovn-encap-type=geneve, ovn-openflow-probe-interval="30",
ovn-remote="tcp:10.6.20.84:6642,tcp:10.6.20.85:6642,tcp:10.6.20.86:6642",
ovn-remote-probe-interval="30000", system-id="gateway-1"}
========
I still see error from ovn-controller.
========
2020-08-07T03:17:48.186Z|02737|reconnect|ERR|tcp:127.0.0.1:6640: no response to
inactivity probe after 8.74 seconds, disconnecting
========
That tcp:127.0.0.1:6640 is the connection between ovn-controller
and local ovsdb-server.
Any settings I missed?
Thanks!
Tony
