RabbitMQ not starting after reboot

Asked by Kanthi Kiran N on 2011-06-17

Hi All,

I had a successful setup of Single node OpenStack(cactus release) setup with Dashboard(vnc) until i restarted the system accidentally. Upon reboot I am unable to use the same. I realised that RabbitMQ is not starting. Please suggest. Following are the logs.

Erlang has closed

You probably have a corrupted mnesia database. If you delete /var/lib/rabbit/mnesia you should be able to start rabbit again.
