# @x-blockdev-change
#
# Dynamically reconfigure the block driver state graph. It can be used
# to add, remove, insert or replace a graph node. Currently only the
# Quorum driver implements this feature to add or remove its child. This
# is useful to fix a broken quorum child.
#
# If @node is specified, it will be inserted under @parent. @child
# may not be specified in this case. If both @parent and @child are
# specified but @node is not, @child will be detached from @parent.
#
# @parent: the id or name of the parent node.
#
# @child: #optional the name of a child under the given parent node.
#
# @node: #optional the name of the node that will be added.
#
# Note: this command is experimental, and its API is not stable. It
# does not support all kinds of operations, all kinds of children, nor
# all block drivers.
#
# Warning: The data in a new quorum child MUST be consistent with that of
# the rest of the array.
#
# Since: 2.7

SQMP
x-blockdev-change
-----------------
Dynamically reconfigure the block driver state graph. It can be used
to add, remove, insert or replace a graph node. Currently only the
Quorum driver implements this feature to add or remove its child. This
is useful to fix a broken quorum child.
If @node is specified, it will be inserted under @parent. @child
may not be specified in this case. If both @parent and @child are
specified but @node is not, @child will be detached from @parent.
Arguments:
- "parent": the id or name of the parent node (json-string)
- "child": the name of a child under the given parent node (json-string, optional)
- "node": the name of the node that will be added (json-string, optional)
Note: this command is experimental, and not a stable API. It doesn't
support all kinds of operations, all kinds of children, nor all block
drivers.
Warning: The data in a new quorum child MUST be consistent with that of
the rest of the array.
Example:
Add a new node to a quorum
-> { "execute": "blockdev-add",
"arguments": { "options": { "driver": "raw",
"node-name": "new_node",
"file": { "driver": "file",
"filename": "test.raw" } } } }
<- { "return": {} }
-> { "execute": "x-blockdev-change",
"arguments": { "parent": "disk1",
"node": "new_node" } }
<- { "return": {} }
Delete a quorum's node
-> { "execute": "x-blockdev-change",
"arguments": { "parent": "disk1",
"child": "children.1" } }
