Re: Agent out of sync with plugin!

Logan, thanks for your reply. I've been very conscientious of NTP, so I'm very confident that that is not an issue.

Gary: so in this case the "agent"= quantum-plugin-openvswitch-agent

"agent"== quantum-plugin-openvswitch-agent - yes

, and "plugin" = quantum-server.

"plugin" == quantum-server - yes. The quantum service runs the plugin.

That's confusing. And what you're saying is that the ovs plugin/agent - whatever it is - is simply stating that it assumes it's out of sync since it's starting up, and it's going to phone home. Is that right? Thanks!

Yes, that is correct. Even the first time that it starts it is out of sync :)

    I traced it to this .py file:

    would still like to know what this means.  Thanks!

    The Quantum agents need to retrieve the port data from the Quantum
    service. When the agents start this is done automatically (hence
    the message that you have seen). This can also happen if there is
    an exception in the agent or if the agent is unable to communicate
    with the service - for example there is a problem with the
    connection between the agent and the service (link down, etc).
