Hello All Need some help to tune scrubbing. 1. How to control not run scrubbing and deep scrubbing together and which one should be started first? 124 active+clean+remapped 35 active+clean+scrubbing+deep 24 active+clean+scrubbing 4 active+clean+remapped+scrubbing+deep I have osd_max_scrubs =1 but still impacting IO’s special when both are running together. 2. When changing some priorities to not to impact IO’s, Setting higher number is lower priority or it works differently with different kind of priority parameters? What is the standard of defining high and low priority(higher number is lower priority or lower number is lower priory etc...) on CEPH? eg: osd_requested_scrub_priority - 170 (120 default) Eg: ceph config set osd osd_scrub_event_cost 8192 (4096 default) Regards Dev
