Using the wrong character resulted in the wrong title level being used for the response codes, which in turn caused the "detail" show/hide toggle to not be able to hide all of the per-endpoint details. This corrects these to be at the correct level. Also ran into issues after changing them where sphinx was not happy with the random title levels. This appears to be due to the order processed and whether not earlier included files had all subsequent levels. Adding an additional title in our first included file resolved that problem.

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:
|
|
|
|

Response Example

|
Create a volume
|
|
~~~~~~~~~~~~~~~
|
|
|
|
.. rest_method:: POST /v3/{project_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.

Asynchronous Postconditions
|
|
|
