In Volumes (volumes) v2/v3 API methods, the request parameter 'volume_id' should be a 'path' param in request param table, not a 'body' param. Closes-bug: #1691989 Change-Id: If931d05504d4f050e7da4f4df6f8d49d4318c95d

Volumes (volumes)
|
|
=================
|
|
|
|
A volume is a detachable block storage device similar to a USB hard
|
|
drive. You can attach a volume to one instance at a time.
|
|
|
|
The ``snapshot_id`` and ``source_volid`` parameters specify the ID
|
|
of the snapshot or volume from which this volume originates. If the
|
|
volume was not created from a snapshot or source volume, these
|
|
values are null.
|
|
|
|
When you create, list, update, or delete volumes, the possible
|
|
status values are:
|
|
|
|

Create volume
|
|
~~~~~~~~~~~~~
|
|
|
|
.. rest_method:: POST /v2/{tenant_id}/volumes
|
|
|
|
Creates a volume.
|
|
|
|
To create a bootable volume, include the UUID of the image from
|
|
which you want to create the volume in the ``imageRef`` attribute
|
|
in the request body.
|
|
|
|
Preconditions
|
|
|
|
- You must have enough volume storage quota remaining to create a
|
|
volume of size requested.
|
|
|
|
Asynchronous Postconditions
|
|
|
|
- With correct permissions, you can see the volume status as
|
|
``available`` through API calls.
|
|
|
|
- With correct access, you can see the created volume in the storage
|
|
system that OpenStack Block Storage manages.
|
|
|
|
Troubleshooting
|
|
|
|
- If volume status remains ``creating`` or shows another error
|
|
status, the request failed. Ensure you meet the preconditions
|
|
then investigate the storage back end.
|
|
|
|
- Volume is not created in the storage system that OpenStack Block
|
|
Storage manages.
|
|
|
|
- The storage node needs enough free storage space to match the size
|
|
of the volume creation request.
