I'm going to mark this as a dup of 1879578. If that is not correct, please let me know. ** Changed in: horizon Status: In Progress => Invalid ** Also affects: cinder Importance: Undecided Status: New ** This bug has been marked a duplicate of bug 1879578 cinder assigns default volume_type even when it shouldn't -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Dashboard (Horizon). https://bugs.launchpad.net/bugs/1885357 Title: Horizon fails to create volume from snapshot of non-standard-type volume Status in Cinder: New Status in OpenStack Dashboard (Horizon): Invalid Bug description: Horizon offers the opportunity to create a volume from a snapshot. It does not, however, properly determine the type of the originating volume of the snapshot and tries to use the default. In environments with non-default storage types (e.g. encrypted storages, like in our case), this fails and leads to an error message: 2020-06-26 16:13:12,633 36 WARNING horizon.exceptions Recoverable error: Invalid input received: Invalid volume_type provided: d4917a31-3332-4323-9b1f-9ace3dda9d9a (requested type is not compatible; recommend omitting the type argument). (HTTP 400) (Request-ID: req-40ee2f61-6a16-44f2-96d7-46f5c42f1942) Problematic code is in cinder/forms.py of Horizon: https://github.com/openstack/horizon/blob/master/openstack_dashboard/dashboards/project/volumes/forms.py#L379 Under normal circumstances, the storage type should be set in that file in "prepare_source_fields_if_snapshot_specified" (https://github.com/openstack/horizon/blob/master/openstack_dashboard/dashboards/project/volumes/forms.py#L145) That code would need to be triggered in the __init__ function of CreateForm (https://github.com/openstack/horizon/blob/master/openstack_dashboard/dashboards/project/volumes/forms.py#L297) which tests the GET of the original request for certain strings. Debugging however, unveils that GET simply does not contain any of the strings checked for there anymore -- in our case, it always was "<WSGIRequest: GET '/dashboard/project/volumes/create/'>". So in fact, the whole code path starting at https://github.com/openstack/horizon/blob/master/openstack_dashboard/dashboards/project/volumes/forms.py#L314 might be dead and the default will always be used. The default doesn't populate "type", however, This of course also leads to creating volumes from volumes not working due to the same issue. Found with the help of Harald Wagener.
