Brian Rosmaita 2023-07-31 21:29:39 UTC Doc Text Cause: In OSP 13, the ability to create a multiattach volume by passing a request parameter in the volume-create request was deprecated for removal as unsafe. The preferred method for creating a multiattach volume is to use a volume-type that enables multiattach.

Consequence: Creating a multattach volume on a backend that does not provide proper multiattach support can lead to data loss.

Fix: It is no longer possible to create a multiattach volume independently of using a volume-type that allows multiattach.

Result: Some Block Storage API requests that were previously acceptable will be rejected with a 400 (Bad Request) response code accompanied by an informative error message.
