There's another problem with this: you're making rabbit3 believe that 
rabbi1 and rabbit2 are in the same cluster, which will lead to bad things.

So the correct way of doing this would be

rabbitctl -n rabbit2 stop_app
rabbitctl -n rabbit2 reset
rabbitctl -n rabbit2 cluster rabbit1 at dfooks-ubuntu64
rabbitctl -n rabbit2 start_app

to cluster rabbit2 with rabbit1, and then what Simon said.
