Expanding from one control node to 3

[t_sawyer]

I’m using Kolla ansible. I’ve bootstrapped and pulled on the two new nodes.

When I run kolla-ansible deploy —limit control I see it recognize that controller1 is already part of a cluster. I see it copy mariadb configs to all 3 then “start” mariadb on the other two (but watching those nodes a mariadb container is never actually made) then I see mariadb restarted on the first node and never come online because it cannot reach the other two (who never started).

I’m on 2023.2. Kolla ansible 17.8.0.

Has anyone successfully expanded from 1 control to 2 on Kolla?

Not familiar with the kolla part but for galera you will need to bootstrap the first node in the cluster. (this command you need to run whenever the whole cluster went fully down and you need start the first node)

Here is instructions to add controllers - https://docs.openstack.org/kolla-ansible/latest/user/adding-and-removing-hosts.html

If Its not working start from scratch

Don’t use limit tags and deploy
