Ceph pgs not deep-scrubbed in time

1. Change scrub_interval

ceph config set osd osd_deep_scrub_interval 1814400
ceph tell osd.* config set osd_deep_scrub_interval 1814400

2. Temporarily increase the number of active scrub tasks

ceph tell 'osd.*' injectargs --osd_max_scrubs=2

3. Check LA and increase osd_scrub_load_threshold

ceph tell 'osd.*' injectargs --osd_scrub_load_threshold=5

4. Force deep scrub tasks

ceph health detail | grep "not deep-scrubbed since" | awk '{ print $2 }' | xargs -n1 ceph pg deep-scrub
