Is this the primary reason grafana is throwing up on me when trying to view the Cyberbot project?

Unfortunately, the work performed wasn't enough (as it still left the host with spinning disks) and the graphite service hammering them bogs down the server.  As a solution, we will be reinstalling the system on 2016-06-23 from 15:00 GMT to 23:00 GMT.  I don't expect to use the majority of this window, since much of the data was migrated backup previously.  However, it is a possibility if we have to re-sync all the data (without differential).
