OpenStack Block Storage (Cinder)
e2c3bcc6e3
The initial cinder design[1][2][3] allowed users to create mutliattach volumes by spcifying the ``multiattach`` parameter in the request body of volume create operation (``--allow-multiattach`` option in cinderclient). This functionality changed in Queens with the introduction of microversion 3.50[4] where we used volume types to store the multiattach capabilities. Any volume created with a multiattach volume type will be a multiattach volume[5]. While implementing the new functionality, we had to keep backward compatibility with the *old way* of creating multiattach volumes. We deprecated the ``multiattach`` (``--allow-multiattach`` on cinderclient side) parameter in the queens release[6][7]. We also removed the support of the ``--allow-multiattach`` optional parameter from cinderclient in the train release[8] but the API side never removed the compatibility code to disallow functionality of creating multiattach volumes by using the ``multiattach`` parameter (instead of a multiattach volume type). This patch removes the support of providing the ``multiattach`` parameter in the request body of a volume create operation and will fail with a BadRequest exception stating the reason of failure and how it can be fixed.
