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.

|
|
| *snap-spec* is [*pool-name*]/*image-name*\ @\ *snap-name*
|
