Attachments (attachments)
=========================
Lists all, lists all with details, shows details for, creates, and
deletes attachment.
.. note:: Everything except for `Complete attachment` is new as of the 3.27
microversion. `Complete attachment` is new as of the 3.44
microversion.
When you create, list, update, or delete attachment, the possible
status values are:
**VolumeAttachment statuses**
+------------------+--------------------------------------------------------+
| Status | Description |
+------------------+--------------------------------------------------------+
| attached | A volume is attached for the attachment. |
+------------------+--------------------------------------------------------+
| attaching | A volume is attaching for the attachment. |
+------------------+--------------------------------------------------------+
| detached | A volume is detached for the attachment. |
+------------------+--------------------------------------------------------+
| reserved | A volume is reserved for the attachment. |
+------------------+--------------------------------------------------------+
| error_attaching | A volume is error attaching for the attachment. |
+------------------+--------------------------------------------------------+
| error_detaching | A volume is error detaching for the attachment. |
+------------------+--------------------------------------------------------+
| deleted | The attachment is deleted. |
+------------------+--------------------------------------------------------+
Delete attachment
~~~~~~~~~~~~~~~~~
.. rest_method:: DELETE /v3/{project_id}/attachments/{attachment_id}
Deletes an attachment.
For security reasons (see bug `#2004555
<https://bugs.launchpad.net/nova/+bug/2004555>`_) the Block Storage API rejects
REST API calls manually made from users with a 409 status code if there is a
Nova instance currently using the attachment, which happens when all the
following conditions are met:
- Attachment has an instance uuid
- VM exists in Nova
- Instance has the volume attached
- Attached volume in instance is using the attachment
Calls coming from other OpenStack services (like the Compute Service) are
always accepted.
Available starting in the 3.27 microversion.
