Hello Guys,

I've just upgraded from openstack queens to rocky and then to stein on centos 7.

In my configuration I have router high availability.

After the upgrade and rebooting each controller one by one I get the following errors on all my 3 controllers under /var/log/neutron/l3-agent.log

If I run openstack router show for for one of uuid in the log:

Namespace for router in present on all 3 controllers.

After the controllers reboot,some routers lost their routing tables, but restarting l3-agent they went ok.

Is it possible router ha stopped working?

Any idea,please ?

Ignazio
