To evacuate a node, either one of the ``iallocator`` or ``remote_node``
|
|
| 1172 |
parameters must be passed::
|
|
| 1171 |
Returns a job ID. The result of the job will contain the IDs of the
|
|
| 1172 |
individual jobs submitted to evacuate the node.
|
|
| 1173 | 1173 |
|
| 1174 |
evacuate?iallocator=[iallocator] |
|
| 1175 |
evacuate?remote_node=[nodeX.example.com] |
|
| 1176 |
|
|
| 1177 |
The result value will be a list, each element being a triple of the job |
|
| 1178 |
id (for this specific evacuation), the instance which is being evacuated |
|
| 1179 |
by this job, and the node to which it is being relocated. In case the |
|
| 1180 |
node is already empty, the result will be an empty list (without any |
|
| 1181 |
jobs being submitted). |
|
| 1174 |
Body parameters: |
|
| 1182 | 1175 |
|
| 1183 |
And additional parameter ``early_release`` signifies whether to try to |
|
| 1184 |
parallelize the evacuations, at the risk of increasing I/O contention |
|
| 1185 |
and increasing the chances of data loss, if the primary node of any of |
|
| 1186 |
the instances being evacuated is not fully healthy. |
|

.. opcode_params:: OP_NODE_EVACUATE |

:exclude: nodes |

If the dry-run parameter was specified, then the evacuation jobs were |
|
| 1189 |
not actually submitted, and the job IDs will be null. |
|
| 1179 |
Up to and including Ganeti 2.4 query arguments were used. Those are no |
|
| 1180 |
longer supported. The new request can be detected by the presence of the |
|
| 1181 |
:pyeval:`rlib2._NODE_EVAC_RES1` feature string. |
