Hello, fuelers. I'm using Fuel 4.1A + Havana in HA mode.
I permanently observe (on other deployments also) issue with stuck "nova-compute" service. But i think problem is more fundamental and relates to HA RabbitMQ and OpenStack AMQP driver implementation. Symptoms: - Random nova-compute from time to time marked as "XXX" for a while. - I see that service itself works properly. In logs i see that it sends status updates to conductor. But actually nothing is sent. - "netstat" shows that all connections to/from rabbit "ESTABLISHED" - rabbitmqctl shows that "compute.node-x" queue synced to all slaves. - nothing has been broken before, i mean rabbitmq cluster, etc. Axe style solution: - /etc/init.d/openstack-nova-compute restart So here i've found a lot of interesting stuff (and solutions): https://bugs.launchpad.net/oslo.messaging/+bug/856764 My questions are: - Are there any thoughts particular for Fuel to solve/workaround this issue? - Any fast solution for this in 4.1? Like adjust TCP keep-alive timeouts? -- Roman Sokolkov, Deployment Engineer, Mirantis, Inc. Skype rsokolkov, rsokol...@mirantis.com
