Unable to delete image from glance cinder store

[Simon Dodsley]

OpenStack master branch built using Devstack 6/30/23

Configuring glance to use cinder backends as multistores.

Configuration works as documented and images can be created in the cinder backend, however when trying to delete any image from glance that is located in a cinder store this will fail with the following:

stack@multi1:~$ glance image-delete 7934ed5e-9958-47e2-9a6a-5aab9a33dfca
'HTTP 500 Internal Server Error: The server has either erred or is incapable of performing the requested operation.': Unable to delete image '7934ed5e-9958-47e2-9a6a-5aab9a33dfca'

The image in question is:

stack@multi1:~$ glance image-show 7934ed5e-9958-47e2-9a6a-5aab9a33dfca

I understood that HTTP stores were read-only, but you should definitely be able to delete an image from a cinder backend store - it is only a volume in the end.

Incorrect glance-api conf file.
Once the correct information was in there it works fine
