Hi charmhub folks!
I with my team are curious about deploying juju without MAAS, so we did it at last 2 months ago and it was running well until several days ago. We found that api controller with only 1 machine suddenly flapping, the service of controller in systemd was running, but from logs, it was dead then up again to serve requests. So, when we try to use juju commands (ex: juju status, juju machines, etc) it was taking long times, and also the status of our applications and machines were flapping in down/up state, but it accessible
So, we try to add more controllers to make it Highly Available using juju enable-ha command. But we stuck because juju said error that it require space, then we try to config the controller to use space that we manually created from juju space create, and using juju controller-config juju-ha-space=‘name-of-space’ for configuring ha-space
ERROR invalid config "juju-ha-space"="controller-mongospace": machines with no addresses in this space: 0
Any suggestion for enabling HA in juju without using MAAS ?
Juju version: 2.9.42
