-To evacuate a node, either one of the ``iallocator`` or ``remote_node``
-parameters must be passed::
+Returns a job ID. The result of the job will contain the IDs of the

+Body parameters:

+.. opcode_params:: OP_NODE_EVACUATE
+ :exclude: nodes
-The result value will be a list, each element being a triple of the job
-id (for this specific evacuation), the instance which is being evacuated
-by this job, and the node to which it is being relocated. In case the
-node is already empty, the result will be an empty list (without any
-jobs being submitted).
+Up to and including Ganeti 2.4 query arguments were used. Those are no
+longer supported. The new request can be detected by the presence of the
+:pyeval:`rlib2._NODE_EVAC_RES1` feature string.
-And additional parameter ``early_release`` signifies whether to try to
-parallelize the evacuations, at the risk of increasing I/O contention
-and increasing the chances of data loss, if the primary node of any of
-the instances being evacuated is not fully healthy.
+Job result:
-If the dry-run parameter was specified, then the evacuation jobs were
-not actually submitted, and the job IDs will be null.

``/2/nodes/[node_name]/migrate``
~~~~~~~~
If no mode is explicitly specified, each instances' hypervisor default
-migration mode will be used. Query parameters:
+migration mode will be used. Body parameters:
-``live`` (bool)
- If set, use live migration if available.
-``mode`` (string)
- Sets migration mode, ``live`` for live migration and ``non-live`` for
- non-live migration. Supported by Ganeti 2.2 and above.
+.. opcode_params:: OP_NODE_MIGRATE
+ :exclude: node_name
+
+The query arguments used up to and including Ganeti 2.4 are deprecated

``/2/nodes/[node_name]/role``
The role is always one of the following:
- drained
- - master
- master-candidate
- offline
- regular
