+
+ Instructions for use
+ --------------------
+
+ 1) Map a Linux block device to an existing rbd image.
+
+ Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
+
+ $ echo "192.168.0.1 name=admin rbd foo" > /sys/class/rbd/add
+
+ The snapshot name can be "-" or omitted to map the image read/write.
+
+ 2) List all active blkdev<->object mappings.
+
+ In this example, we have performed step #1 twice, creating two blkdevs,
+ mapped to two separate rados objects in the rados rbd pool
+
+ $ cat /sys/class/rbd/list
+ #id major client_name pool name snap KB
+ 0 254 client4143 rbd foo - 1024000
+
+ The columns, in order, are:
+ - blkdev unique id
+ - blkdev assigned major
+ - rados client id
+ - rados pool name
+ - rados block device name
+ - mapped snapshot ("-" if none)
+ - device size in KB
+
+
+ 3) Create a snapshot.
+
+ Usage: <blkdev id> <snapname>
+
+ $ echo "0 mysnap" > /sys/class/rbd/snap_create
+
+
+ 4) Listing a snapshot.
+
+ $ cat /sys/class/rbd/snaps_list
+ #id snap KB
+ 0 - 1024000 (*)
+ 0 foo 1024000
+
+ The columns, in order, are:
+ - blkdev unique id
+ - snapshot name, '-' means none (active read/write version)
+ - size of device at time of snapshot
+ - the (*) indicates this is the active version
+
+ 5) Rollback to snapshot.
+
+ Usage: <blkdev id> <snapname>
+
+ $ echo "0 mysnap" > /sys/class/rbd/snap_rollback
+
+
+ 6) Mapping an image using snapshot.
+
+ A snapshot mapping is read-only. This is being done by passing
+ snap=<snapname> to the options when adding a device.
+
+ $ echo "192.168.0.1 name=admin,snap=mysnap rbd foo" > /sys/class/rbd/add
+
+
+ 7) Remove an active blkdev<->rbd image mapping.
+
+ In this example, we remove the mapping with blkdev unique id 1.
+
+ $ echo 1 > /sys/class/rbd/remove
+
+
+ NOTE: The actual creation and deletion of rados objects is outside the scope
+ of this driver.
