 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
-cluster (you can read and write data) or it is out of the cluster ``out``.  If
-it is ``down``, it should also be ``out``. If an OSD is ``down`` and ``in``,
