It means pretty much what it says. rabbitmqctl cluster is used to set up 
a cluster, and should only be used when the rabbit application has been 
stopped (which stops mnesia too). See:


The command you're looking for is:

rabbitmqctl status

By the way, it's a good idea to keep the mailing list CCed so that if 
other people have the same problem they can find the thread...
