Hi Bernie,
Here is "HA for OVN DB servers using pacemaker":
http://docs.openvswitch.org/en/latest/topics/integration/?highlight=HA%20for%20OVN%20DB%20servers%20using%20pacemaker#ha-for-ovn-db-servers-using-pacemaker
This implementation of the OVNDB "Active/Backup" mode of high reliability.
Gateway high reliability seems to have a plan, the current situation I
do not know.
http://docs.openvswitch.org/en/latest/topics/high-availability/#ovn-gateway-high-availability-plan
You can prepare multiple gateways, "networking-ovn" will automatically
schedule the gateway when it is down.
I do not know if the OVN gateway supports ECMP。
Good day, all
Please excuse the amateurish question. This is my first crack at OVN.
Is there some sort of deployment guide that for high availability? I
have a use case for OVN but don’t immediately see how to get away from
a e.g. a controller or gateway node being the single point of failure.
I started thinking about two gateways and ECMP on the outside of the
environment but not sure how this manifests on the southbound side.
Cheers
Bernie
