[rabbitmq-discuss] RabbitMQ cluster issue

[Codevally]

Hi

I have a 2 node RabbitMQ cluster and want to add another node to it.
All 3 nodes are running on Linux.

The rabbit at app1 and rabbit at app2 are already in the cluster and working
fine. I want to integrate rabbit at app9 as well to the cluster.

rabbit at app9 is working file in the standalone mode, but if I follow
the below commands, it says "Error: {no_running_cluster_nodes,
[rabbit at app1],[rabbit at app1]}".
