[Bug 2033885] [NEW] Mounting Synology Volumes in Openstack

Fri Sep 1 11:31:54 UTC 2023 

Public bug reported:

There is a current issue where we are no longer able to mount Synology
Volumes in Openstack. We can create volumes, but when attempting to
attach to an instance we receive an error from Nova Compute. This
feature was working, but has stopped working even though no apparent
configuration hanges that would affect this have been made.

1) Ubunutu Release: 22.04.3 LTS
2) Openstack 6.0.0
3) We expected our synology volumes to mount correctly
4) We receive an error from Nova Compute
