Ah! Glad you sorted this out.

However, you might want to put this customisation into 
/etc/rabbitmq/rabbitmq-env.conf instead (in a slightly different form):

MNESIA_BASE=/mnt/data/rabbitmq/mnesia

See:

http://www.rabbitmq.com/man/rabbitmq-env.conf.5.man.html
http://www.rabbitmq.com/relocate.html

The reason is that the rabbitmq-env file you edited is part of the 
installation - so the next time you upgrade it will get overwritten 
again and things will break again...

Cheers, Simon
