Hi guys,
I was trying to add new backend node
It showed an error during installation related to elasticsearch.
So now if I run chef-backend-ctl status
An unexpected error occurred:
LibCB::Status::ServiceNotFound
I was trying to remove broken node from the main backend, but it fails 
chef-backend-ctl remove-node 192.168.9.240 --verbose
Could not find node ‘192.168.9.240’ in /cb/status
I inferred the existence of this node: 192.168.9.240 / 947ba20bd49d089f98b9ba976b9820c7
Would you like me to try to remove this node?
