.. -*- rst -*- Volume actions (volumes, action) ================================ Extends the size of, resets statuses for, sets image metadata for, and removes image metadata from a volume. Attaches a volume to a server, detaches a volume from a server, and removes a volume from Block Storage management without actually removing the back-end storage object associated with it. Extend a volume size ~~~~~~~~~~~~~~~~~~~~ .. rest_method:: POST /v3/{project_id}/volumes/{volume_id}/action Extends the size of a volume to a requested size, in gibibytes (GiB). Specify the ``os-extend`` action in the request body. Preconditions - Prior to microversion ``3.42`` the volume status must be ``available``. Starting with microversion ``3.42``, attached volumes with status ``in-use`` may be able to be extended depending on policy and backend volume and compute driver constraints in the cloud. Note that ``reserved`` is not a valid state for extend. - Sufficient amount of storage must exist to extend the volume. - The user quota must have sufficient volume storage. Postconditions - If the request is processed successfully, the volume status will change to ``extending`` while the volume size is being extended. - Upon successful completion of the extend operation, the volume status will go back to its original value. - Starting with microversion ``3.42``, when extending the size of an attached volume, the Block Storage service will notify the Compute service that an attached volume has been extended. The Compute service will asynchronously process the volume size change for the related server instance. This can be monitored using the ``GET /servers/{server_id}/os-instance-actions`` API in the Compute service. Troubleshooting - An ``error_extending`` volume status indicates that the request failed. Ensure that you meet the preconditions and retry the request. If the request fails again, investigate the storage back end.

It is generally not recommended to retype an *in-use* multiattach volume if that volume has more than one active read/write attachment. Policy defaults enable only users with the administrative role or the owner of the volume to perform this operation. Cloud providers can change these permissions through the policy.json file.
