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
- Volume status must be ``available``.
- Sufficient amount of storage must exist to extend the volume.
- The user quota must have sufficient volume storage.
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.
