-blockdev-group-snapshot-sync
-----------------------
-
-Synchronous snapshot of one or more block devices. A list array input
-is accepted, that contains the device and snapshot file information for
-each device in group. The default format, if not specified, is qcow2.
+transaction
+-----------
-If there is any failure creating or opening a new snapshot, all snapshots
-for the group are abandoned, and the original disks pre-snapshot attempt
-are used.
+Atomically operate on one or more block devices. The only supported
+operation for now is snapshotting. If there is any failure performing
+any of the operations, all snapshots for the group are abandoned, and
+the original disks pre-snapshot attempt are used.
+A list of dictionaries is accepted, that contains the actions to be performed.
+For snapshots this is the device, the file to use for the new snapshot,
+and the format. The default format, if not specified, is qcow2.
Arguments:
-devlist array:
- - "device": device name to snapshot (json-string)
- - "snapshot-file": name of new image file (json-string)
- - "format": format of new image (json-string, optional)
+actions array:
+ - "type": the operation to perform. The only supported
+ value is "blockdev-snapshot-sync". (json-string)
+ - "data": a dictionary. The contents depend on the value
+ of "type". When "type" is "blockdev-snapshot-sync":
+ - "device": device name to snapshot (json-string)
+ - "snapshot-file": name of new image file (json-string)
+ - "format": format of new image (json-string, optional)
Example:
--> { "execute": "blockdev-group-snapshot-sync", "arguments":
- { "devlist": [{ "device": "ide-hd0",
- "snapshot-file": "/some/place/my-image",
- "format": "qcow2" },
- { "device": "ide-hd1",
- "snapshot-file": "/some/place/my-image2",
- "format": "qcow2" }] } }
+-> { "execute": "transaction",
+ "arguments": { "actions": [
+ { 'type': 'blockdev-snapshot-sync', 'data' : { "device": "ide-hd0",
+ "snapshot-file": "/some/place/my-image",
