================================
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 volume size
==================

.. rest_method::  POST /v2/{tenant_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.
