+=========================================
+ rbdmap -- map RBD devices at boot time
+=========================================
+
+.. program:: rbdmap
+
+Synopsis
+========
+
+| **rbdmap map**
+| **rbdmap unmap**
+
+
+Description
+===========
+
+**rbdmap** is a shell script that can be run manually by the system
+administrator at any time, or automatically at boot time by the init system
+(sysvinit, upstart, systemd). The script looks for an environment variable
+``RBDMAPFILE``, which defaults to ``/etc/ceph/rbdmap``. This file is
+expected to contain a list of RBD images and, possibly, parameters to be
+passed to the underlying ``rbd`` command. The syntax of
+``/etc/ceph/rbdmap`` is described in the comments at the top of that file.
+
+The script mounts devices after mapping, and unmounts them before
+unmapping.
+
+
+Options
+=======
+
+None
+
+
+Availability
+============
+
+**rbdmap** is part of Ceph, a massively scalable, open-source, distributed
+storage system. Please refer to the Ceph documentation at
+http://ceph.com/docs for more information.
