• The correct role is mongodb-org-3.2.yml, all the other ones must be removed and that one renamed
• The used playbook is mongodb-org.yml. It can be renamed to mongod.yml and removed the duplicate calls to some roles (data_disk, nagios)
• The mongo_vol group must be split between prod and dev, and the mongo vol nodes added to the main inventory files.

The mongo playbook should be changed, in future, to:

• Distribute the configuration
• Manage the users
• Manage the upgrades, handling the primary/secondary transitions.
