Hi,

I do not familiar with mirantis os 9, but in general there is an architecture when vm can be still accessible even without controller.

Also, there is a guide for HA deployment, here are for controllers in particular - https://docs.openstack.org/ha-guide/controller-ha.html

Hi guys,
I'm new to openstack.

If one of controllers goes down - vm machines are not accesible, I
though openstack supposed to work even if one controller is alive

Any thoughts?
