Hi, we are running a Cinder Pike instance with Ceph (luminous) backend for use with oVirt (not openstack). We are experiencing the "cinder-volume causes high CPU load" issue. In Cinder 11.0.0 we could successfully apply the fix mentioned in https://ask.openstack.org/en/question/110709/ocata-cinder-volume-causes-high-cpu-load-ceph-backend/. In Cinder 11.0.1 /usr/lib/python2.7/site-packages/cinder/volume/drivers/rbd.py changed, but the high CPU load problem reappeared. I tried changing "report_dynamic_total_capacity" (mentioned in the changelog), but it didn't make a difference. Has anyone seen/fixed this? thx matthias
