Hi, The openstak documentation says that glance supports cinder as backend, but it does not exclude any backend used by cinder itself. I'm having trouble configuring glance to use a cinder backend which is backed by an nfs share. Is this configuration supported? First, the rootwrap was missing, after adding it, I faced the lack of privileges, which was corrected by starting the glance-api container in privileged mode and finally I am facing a non existing filter error. Glance is trying to mount the nfs share to use it!!! Which I don't understand , why mount a share that is already mounted by cinder which glance is supposed to use as an intermediary!!!? When I push an image I get this error: Stderr: '/var/lib/kolla/venv/bin/glance-rootwrap: Unauthorized command: mount -t nfs 20.1.0.32:/kolla_nfs /var/lib/glance/mnt/nfs/f6f6b4ee42b4f3522a75f422887010ad2c47f8624 f97bf3623b13014f22186b7 (no filter matched)\n' Regards.
