[ceph-users] ceph and openstack throttling experience

Hi We're running ceph nautilus 14.2.21 (going to octopus latest in a few weeks) as volume and instance backend for our openstack vm's. Our clusters run somewhere between 500 - 1000 OSDs on SAS HDDs with NVMe's as journal and db device Currently we do not have our vm's capped on iops and throughput. We regularly get slowops warnings (once or twice per day) and wonder whether there are more users with sort of the same setup that do throttle their openstack vm's. - What kind of numbers are used in the field for IOPS and throughput limiting? - As a side question, is there an easy way to get rid of the slowops warning besides restarting the involved osd. Otherwise the warning seems to stay forever Regards Marcel
