'systemctl start ceph-radosgw' is not starting the radosgw, "/bin/radosgw is not running"

Issue

• Other ceph commands work such as ceph -s
• When running the command systemctl start ceph-radosgw the radosgw fails to start with the following output in systemctl status ceph-radosgw:

ceph-radosgw.service - LSB: radosgw RESTful rados gateway
   Loaded: loaded (/etc/rc.d/init.d/ceph-radosgw)
   Active: failed (Result: exit-code) since Tue 2015-07-07 12:43:11 PDT; 8s ago

• The output isn't very useful, only stating /bin/radosgw is not running. How do I figure out more information on why radosgw will not start?
