Hi Sven,
you can set a different interval per pool:
ceph osd pool set <POOL> deep_scrub_interval 1209600
I have some more insights about "PGs not deep-scrubbed in time"
summarized here:

Zitat von Sven Grottke <[email protected]>:
Hi,
we are operating a Ceph cluster with mostly replicated pools on
SSDs, but one of our pools is erasure-coded on 16TB HDDs.
Two weeks ago, we upgraded from Reef to Squid (19.2.3). Since then,
there has been an ever growing number of PGs that have not been
deep-scrubbed or scrubbed in time. All these PGs are located on the
HDD pool.
I would like to increase the scrubbing and deep-scrubbing intervals
for the HDDs, but not for the SSDs. Is there any way to do that
other than setting it on a per-OSD base, such as per device class or
per sub-tree of the crush map?
Thanks in advance for any advice!
Ciao, Sven
