[rdo-users] [tripleo][cinder][horizon]Unable to use Cinder volume as _member_ or member in Horizon

Hello everyone, Lately I run into two problems with using TripleO to deploy OpenStack (Queens). One of them is that users with _member_ or member roles appear to be unable to use cinder-volume service via the Dashboard (Horizon). For any projects, users with either _member_ or member role received following pop-up error messages while trying to launch instances: Error: Unable to retrieve volumes Error: Unable to retrieve volume snapshots There is also no volume option to choose from the drop-down menu in the Source sector, although the bootable volume is present and publicly accessible. It doesn't affect the same users using CLI - they can create volumes or boot instances from volume normally from the command line. The issue is reproducible and consistent with varied cluster configurations and cinder backends (nfs, file, rbd). Has anyone else encountered the same experience? Best regards, Cody
