Hi Michal, Feel free to propose change of default in master branch, but I don’t think we can change the default in stable branches without impacting users. Best regards, Michal

Hello,
RabbitMQ HA has been backported into stable releases, and it’s documented here: https://docs.openstack.org/kolla-ansible/yoga/reference/message-queues/rabbi...
Best regards, Michal

Yes. But cluster cannot work properly without it. :(

This commit explains why they largely removed HA queue durability:

CAUTION: This email originates from outside THG
Are you proposing a solution or just raising an issue?
I did find it strange that kolla-ansible doesn't support HA queue by default. That is a disaster because when one of the nodes goes down it will make the whole rabbitMQ unacceptable. Whenever i deploy kolla i have to add HA policy to make queue HA otherwise you will endup in problem.

I want to summary for who meets problems with Openstack when deploy cluster with 3 controller using Kolla Ansible
Scenario: 1 of 3 controller is down
1. Login horizon and use API such as nova, cinder will be very slow
fix by:
nano: kolla-ansible/ansible/roles/heat/templates/heat.conf.j2 kolla-ansible/ansible/roles/nova/templates/nova.conf.j2 kolla-ansible/ansible/roles/keystone/templates/keystone.conf.j2 kolla-ansible/ansible/roles/neutron/templates/neutron.conf.j2 kolla-ansible/ansible/roles/cinder/templates/cinder.conf.j2
or which service need caches
add as below
[cache] backend = oslo_cache.memcache_pool enabled = True memcache_servers = {{ kolla_internal_vip_address }}:{{ memcached_port }} memcache_dead_retry = 0.25 memcache_socket_timeout = 900
https://review.opendev.org/c/openstack/kolla-ansible/+/849487
but it is not the end
2. Cannot launch instance or mapping block device(stuck at this step)
nano kolla-ansible/ansible/roles/rabbitmq/templates/definitions.json.j2
"policies":[ {"vhost": "/", "name": "ha-all", "pattern": "^(?!(amq\.)|(.*_fanout_)|(reply_)).*", "apply-to": "all", "definition": {"ha-mode":"all"}, "priority":0}{% if project_name == 'outward_rabbitmq' %}, {"vhost": "{{ murano_agent_rabbitmq_vhost }}", "name": "ha-all", "pattern": ".*", "apply-to": "all", "definition": {"ha-mode":"all"}, "priority":0} {% endif %} ]
nano /etc/kollla/global.conf
[oslo_messaging_rabbit] kombu_reconnect_delay=0.5
https://bugs.launchpad.net/oslo.messaging/+bug/1993149 https://docs.openstack.org/large-scale/journey/configure/rabbitmq.html
I used Xena 13.4 and Yoga 14.8.1.
Above bugs are critical, but I see that it was not fixed. I am just an operator and I want to share what I encountered for new people who come to Openstack
