# Upgrading from rabbitmq 3.x to 4.x requires:
|
|
# 1: upgrading to the latest rabbitmq 3.x release and enabling all feature flags
|
|
# 2: removing all rabbitmq 3.x openstack vhost ha policies
|
|
# 3: setting rabbit_ha_queues to false in all openstack component configs
|
|
# 4: wiping the rabbitmq database if rabbit_ha_queues and/or vhost ha policies were used with 3.x

rabbit_ha_queues: false
|
|
|
|
# Note: rabbit_ha_queues is true by default for all openstack components in openstack-helm
|
|
|
|
# Steps to wipe rabbitmq database:
|
|
# 1: rabbitmqctl stop_app
|
|
# 2: rabbitmqctl force_reset
|
|
# 3: rabbitmqctl start_app
|
|
# 4: rerun all openstack component rabbit-init jobs to recreate rabbitmq vhosts and users
|
|
|
|
# Note: rabbitmq classic v2 vs quorum queues
|
|
# With rabbitmq 4.x classic queues have been replaced with classic v2 queues. Classic v2 queues
|
|
# do not support high availability. For HA, quorum queues must be used. Quorum queues are HA by default.
|
|
# Classic v2 queues are the default in Rabbitmq 4.x.
|
|
#
|
|
# To enable quorum queues with rabbitmq 4.x you can use:
|
|
#
|
|
# conf:
|
|
# glance:
|
|
# oslo_messaging_rabbit:
|
|
# rabbit_ha_queues: false
|
|
# rabbit_quorum_queues: true
|
|
# rabbit_transient_quorum_queue: true
|
|
# use_queue_manager: true
