Hello, folks,<br>
<br>
I have a small cluster running openstack liberty, today I am starting to upgrading to Mitaka.<br>
<br>
I am having a problem to launch l3 agent on network node.<br>
<br>
I got the following error:<br>

Option "verbose" from group "DEFAULT" is deprecated for removal. Its value may be silently ignored in the future.<br>

<br>
On our setup, we did not use any FWaaS service, please give us hints what may cause this problem.<br>
</blockquote>
<br></div></div>
First, if you don’t use FWaaS, then why have you installed neutron-fwaas package? Please remove it. Also, make sure that your l3_agent.ini does not contain any fwaas remnants (I suspect you may have [fwaas] enabled = True there). Finally, check that neutron-server does not attempt to load fwaas service plugin (you can check it in log messages from oslo.config that are dumped at the service startup, specifically, check service_plugins value).<br>
