I am deploying OpenStack using Juju Charms. I had a juju controller node deployed under MAAS without HA and it went down one day because of hardware failure. Now I have rebuild the juju controller node but wonder how can I connect the provisioned machine under the new controller.
I tried add-machine command but it turns out my machine has already provisioned.
juju add-machine ssh:email@example.com
ERROR machine is already provisioned
