In v2: Add an explanation regarding GET for volume metadata for a specific key and some parameters regarding key, because those are missed. Modify prameters of volume_id and key for DELETE, because those should be in path. In v3: Add explanations regarding GET and DELETE for volume metadata for a specific key and some parameters regarding key, because those are missed.

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 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.

|
``error_restoring``.
|

|
- You cannot already have a snapshot of the volume.
|
|
|
|
- You cannot delete a volume that is in a migration.
|
|
|
|
Asynchronous Postconditions
|
|
|
|
- The volume is deleted in volume index.

|
|
|
- The volume managed by OpenStack Block Storage is deleted in

|
storage node.

- If volume status remains in ``deleting`` or becomes
|
|
``error_deleting`` the request failed. Ensure you meet the
