Dear colleagues,
for some reasons, linstordrv.py misses passing URI in
_get_volume_stats() which lead to the following problem in cinder-volume
- it was trying to connect to default linstor://localhost
(Resource.__init__(self, name, uri='linstor://localhost') ) instead of
configured linstor://controller :
