Hi,
Unfortunately there is no way of doing this from the Ceph
configuration but you could create some cron jobs to add and remove
the nodeep-scrub flag.
The only problem would be that your cluster status will show
HEALTH_WARN but i think you could set/unset the flags per pool to
avoid this.
Don't disable the deep-srubs, but set the interval for deep scrubbing to
INT_MAX. (or a month if you'd like to play it a bit safer)
And then start scrubbing thru cron.
But as Wido usually says:
"if you can't bear the scrub load, then your cluster is undersized."
And I tend to agree, because the punishment on the cluster in case of
serious remapping can be way much higher.

Hi all,
We have operating hours from 4 pm until 7 am each weekday and 24 hour days in the weekend.
I was wondering if it's possible to allow deep-scrubbing from 7 am until 15 pm only on weekdays and prevent any deep-scrubbing in the weekend.
I've seen the osd scrub begin/end hour settings but that doesn't allow for preventing deep-scrubs in the weekend.
Kind regards,
Caspar
