You can't do 2 control nodes with kolla as you need an odd number of mariadb nodes for quorum purposes (1 or 3 or more). </div>

Hi，</div>
<div dir="ltr">
<div><br>
</div>
<div>I'm a newer in kolla-ansibe. And I could deploy a cluster of two controll nodes by kolla-ansible. But I don't konw whether the cluster is anvailable?</div>
<div><br>
</div>
<div>I would like to ask, when the number of control nodes is 2, the status of mariadb and rabbitmq clusters, are they safe and available for production?<br>
</div>
<div><br>
</div>
<div>Thanks for any guidance.</div>
<div>Good Luck</div>
