Subject: Re: [kolla]RabbitMQ HA policies define

This has been discussed at great length; here are a couple of links that lead to interesting threads:

https://lists.openstack.org/pipermail/openstack-discuss/2021-November/026074.html
https://lists.openstack.org/pipermail/openstack-discuss/2020-August/016362.html

There used to be a useful document here:
https://wiki.openstack.org/wiki/Large_Scale_Configuration_Rabbit

That link now points to the “Large Scale SIG” home page. Does anyone know where the useful RMQ document is? I assume that it is buried somewhere under “Large Scale Journey.”

The bottom line is that, by default, kolla-ansible enables replication but not durable-queues, which is an unstable configuration. I believe that this may have been fixed in a newer version; we are on Train.

Folks,

I have deployed 3 node kolla controllers and notice rabbitMQ doesn't have any HA policy for queues. when i rebooted one of the nodes and found some messages got lost.

Any reason kolla doesn't use HA policies by default?

If i want to add policies then where should i specify them or any doc you can point me to define policies.
