How to debug cluster where instance status is stuck on "scheduling"?
In my OS cluster I have 3 control nodes, 2 load balancers and 2 compute nodes.
When I run nova boot
command or launch a new instance from GUI a status of new created instance always remains as scheduling. I stopped the rabbitmq-server on 2 control nodes but this didn't help .
What may cause this issue ? What are the relevant logs to trace it?
Did you find any good ways of debuging this problem?
