-blockdev-mirror
-------------
-
-Start mirroring a block device's writes to another block device. target
-specifies the target of mirror operation.
-
-Arguments:
-
-- "job-id": Identifier for the newly-created block job. If omitted,
-            the device name will be used. (json-string, optional)
-- "device": The device name or node-name of a root node whose writes should be
-            mirrored (json-string)
-- "target": device name to mirror to (json-string)
-- "replaces": the block driver node name to replace when finished
-              (json-string, optional)
-- "speed": maximum speed of the streaming job, in bytes per second
-  (json-int)
-- "granularity": granularity of the dirty bitmap, in bytes (json-int, optional)
-- "buf_size": maximum amount of data in flight from source to target, in bytes
-  (json-int, default 10M)
-- "sync": what parts of the disk image should be copied to the destination;
-  possibilities include "full" for all the disk, "top" for only the sectors
-  allocated in the topmost image, or "none" to only replicate new I/O
-  (MirrorSyncMode).
-- "on-source-error": the action to take on an error on the source
-  (BlockdevOnError, default 'report')
-- "on-target-error": the action to take on an error on the target
-  (BlockdevOnError, default 'report')
-
-The default value of the granularity is the image cluster size clamped
-between 4096 and 65536, if the image format defines one.  If the format
-does not define a cluster size, the default value of the granularity
-is 65536.
-
-Example:
-
--> { "execute": "blockdev-mirror", "arguments": { "device": "ide-hd0",
-                                                  "target": "target0",
-                                                  "sync": "full" } }
