[Yahoo-eng-team] [Bug 1385234] Re: OVS tunneling between multiple neutron nodes misconfigured if amqp is restarted
** Changed in: neutron Status: Incomplete => Won't Fix -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1385234 Title: OVS tunneling between multiple neutron nodes misconfigured if amqp is restarted Status in neutron: Won't Fix Status in oslo.messaging: Fix Released Status in tripleo: Fix Released Bug description: At completion of a deployment with multiple controllers, by observing the gre tunnels created in OVS by the neutron ovs-agent, one will find that some neutron nodes may miss the tunnels in between them or to the computes. This is due to ovs-agents getting disconnected from the rabbit cluster without them noticing and as a result, being unable to receive updates from other nodes or publish updates. The disconnection may happen following a reconfig of a rabbit node, the VIP moving over a different node when rabbit is load balanced, or even _during_ tripleo overcloud deployment due to rabbit cluster configuration changes. This was observed using Kombu 3.0.33 as well as 2.5. Use of some aggressive (low) kernel keepalive probes interval seems to improve the reliability but a more appropriate fix seems to be support for heartbeat in oslo.messaging To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1385234/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
