om_enable_rabbitmq_quorum_queues is True but non-quorum queues have been found.
|
||||
Currently the procedure to migrate to quorum queues is manual.
|
||||
Please follow the process described here: https://docs.openstack.org/kolla-ansible/latest/reference/message-queues/rabbitmq.html#high-availability.
|
||||
Note that this process may take several hours on larger systems, and may cause a degredation in performance at large scale.
|
||||
If you do not wish to enable this feature, set om_enable_rabbitmq_quorum_queues to False.

A precheck has been added to catch when
|
||||
``om_enable_rabbitmq_quorum_queues`` is set to ``True``, but quorum queues
|
||||
have not been configured on all appropriate queues. A manual migration is
|

required, see here for details:
