==================================================
.. program:: rbd-ggate
Synopsis
========
| **rbd-ggate** [--read-only] [--exclusive] [--device *ggate device*] map *image-spec* | *snap-spec*
| **rbd-ggate** unmap *ggate device*
| **rbd-ggate** list
Description
===========
**rbd-ggate** is a client for RADOS block device (rbd) images. It will
map a rbd image to a ggate (FreeBSD GEOM Gate class) device, allowing
access it as regular local block device.
Commands
========
map
---
Spawn a process responsible for the creation of ggate device and
forwarding I/O requests between the GEOM Gate kernel subsystem and
RADOS.
unmap
-----
Destroy ggate device and terminate the process responsible for it.
list
----
List mapped ggate devices.
Options
=======
.. option:: --device *ggate device*
Specify ggate device path.
.. option:: --read-only
Map read-only.
.. option:: --exclusive
Forbid writes by other clients.
Image and snap specs
====================
| *image-spec* is [*pool-name*]/*image-name*
| *snap-spec* is [*pool-name*]/*image-name*\ @\ *snap-name*
The default for *pool-name* is "rbd". If an image name contains a slash
character ('/'), *pool-name* is required.
Availability
============
**rbd-ggate** 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.
