回答1:

you have had a problem during the database upgrade, it would be interesting see what happened checking the logs

BTW To solve quickly the problem is enough to remove your mnesia directory.

The directory is usually located in /var/lib/rabbitmq/mnesia , check here for detail.

NOTE

By removing the mnesia directory you will lose all your messages
