Ray,
Do you known the IOPS/BW of the cluster? The 16TB HDD is more suitable
for cold data, If the clients' bw/iops is too big, you can never finish
the scrub.
And if you adjust the priority, it will have a great impact to the clients.

We have 16 Storage Servers each with 16TB HDDs and 2TB SSDs for DB/WAL, so we are using bluestore. The system is running Nautilus 14.2.19 at the moment, with an upgrade scheduled this month. I can't give you a complete ceph config dump as this is an offline customer system, but I can get answers for specific questions.
Off the top of my head, we have set:
osd_max_scrubs 20
osd_scrub_auto_repair true
osd _scrub_load_threashold 0.6
We do not limit srub hours.
Thank you,
Ray
