Checking OSD Status
===================
An OSD's status is either in the cluster (``in``) or out of the
cluster (``out``); and, it is either up and running (``up``), or it is down and
not running (``down``). If an OSD is ``up``, it may be either ``in`` in the

it is ``down``, it should also be ``out``. If an OSD is ``down`` and ``in``,
