Hi Andrei,
we have been using the script from [1] to define the number of PGs to
deep-scrub in parallel, we currently use MAXSCRUBS=4, you could start

And these are the scrub settings from our ceph.conf:
ceph:~ # grep scrub /etc/ceph/ceph.conf
Hello,
I am currently running Luminous 12.2.8 on Ubuntu with 4.15.0-36-generic kernel
from the official ubuntu repo. The cluster has 4 mon + osd servers. Each osd
server has the total of 9 spinning osds and 1 ssd for the hdd and ssd pools.
The hdds are backed by the S3710 ssds for journaling
