When running the command nova diagnostics, the output is a number of useful metrics. However, after having pored over both the OpenStack documentation and supplemental documentation provided by Mirantis, I am at a complete loss as to what hdd_errors represents. I have graphed the output after emitting metrics to a StatsD backend, but it has not helped.

Here is the graph in question: https://i.imgur.com/Lo9Ay35.png (https://i.imgur.com/Lo9Ay35.png (Openstack graphs))
