+Volume Attachments
+==================
+
+Nova allows you to attach a volume to a server on the fly. This model represents a point of attachment between a server and a volume.

+.. |models| replace:: volume attachments
+
+.. include:: /common/service.rst
+
+.. warning::
+
+    The server must be fully started before you can attach a volume to it. Just because the server is in the ``ACTIVE``
+    state does not mean that it is ready to accept a volume attachment. See `https://bugs.launchpad.net/nova/+bug/1960346`_
+    and `https://bugs.launchpad.net/nova/+bug/1998148`_ for more information.

+Create
+------
+
+To attach a volume to a server, you need to know the server ID and the volume ID.
