Hello, we don't use a scheduler on OSDs, so priority has no effect. We use this to reduce load during working ours:
osd scrub begin hour = 18 osd scrub end hour = 7 osd scrub load threshold = 3 osd max scrubs = 1 osd max backfill = 3 osd recovery max active = 5 At least " load threshold" has tob e adopted tot he (cpu) power of the host.

I've seen it happening after ceph deep-scrubs start. Googling this, refers me to this page on lowering ceph scrub I/O priority: http://dachary.org/?p=3268 I'd just like to ask here: Anyone followed that procedure? Seems the pve/ceph is recent enough. Any insights to share?
