[rabbitmq-discuss] Rabbitmq up and running but connection_closed_abruptly

Thu Sep 5 21:09:34 BST 2013

Hi,

I am hoping you can help me as no one on the Zenoss forum is.

I am learning a lot about RabbitMQ during this troubleshooting process! :-)

I setup a two node veritas cluster running Zenoss which uses rabbitmq. In 
my configuration, i believe RabbitMQ does not know it is a cluster.

The cluster consists of a SAN drive this is switches between nodes on 
failover. Each node had rabbitmq installed then I move the mnesia database 
to the SAN drive and implemented a rabbitmq-env.conf

 tail /etc/rabbitmq/rabbitmq-env.conf
RABBITMQ_NODENAME=rabbit at localhost
RABBITMQ_MNESIA_BASE=/opt/zenoss/rabbitmq
RABBITMQ_MNESIA_DIR=/opt/zenoss/rabbitmq/mnesia/rabbit\@localhost

By making the rabbitmq nodename localhost, I did not think it would have a 
problem with the failover as both hosts are localhost and it does not seem 
like there is a problem.

RabbitMQ runs fine on both hosts and host B gets an error when the Zenoss 
servers tries to connect to rabbitmq

I am guessing these connections were made originally before the connection 
was closed abruptly?

Can anyone please help?
