I don't like this personally. Your cluster should be capable of doing a deep scrub at any moment. If not it will also not be able to handle a node failure during peak times. > osd_scrub_min_interval 259200 > osd_scrub_max_interval 1814400 > osd_scrub_chunk_max 5 > osd_scrub_sleep .1 You can try to bump that even more.
