I'm trying to understand which settings control light scrubbing and which control deep scrubs. `osd_scrub_begin_hour` and ` osd_scrub_end_hour` are for deep scrubs as far as I can tell even though the documentation just calls them scrubs. What about `osd_scrub_min_interval` and `osd_scrub_max_interval` for example, are they for light or deep scrubs or do these settings control both? The documentation [ https://docs.ceph.com/en/latest/rados/configuration/osd-config-ref/ ] is unclear except for around 6 cases in which "deep scrub", "deep-scrub", and "deep--scrub" are all used interchangeably.
