One way this can happen is if you have the default setting
osd_scrub_during_recovery=false
If you’ve been doing a lot of [re]balancing, drive replacements, topology changes,
expansions, etc. scrubs can be starved especially if you’re doing EC on HDDs.
HDD or SSD OSDs? Replication or EC?
Number of OSDs? Number of PGs? Values of osd_scrub_max interval and
osd_deep_scrub_interval ?

Hi,
we are having problems with really long taking deep-scrubb processes
causing PG_NOT_DEEP_SCRUBBED and ceph HEALTH_WARN. One ph is waiting
since 2020-05-18 for the deep-scrubb.
Is there any way to speed up the deep-scrubbing?
