.Support for randomized scrub scheduling has been added
The new Ceph `osd_scrub_interval_randomize_ratio` configuration option randomizes scrub scheduling by adding a random delay to the value specified by the `osd_scrub_min_interval` option. As a result, scrubbing of newly created pool or placement groups does not happen at the same time, and I/O impact is reduced.

Is this merged in Jewel? I checked the release notes and the git log but couldn't figure it out. I see the configuration variable "osd_scrub_interval_randomize_ratio" in jewel. So I'd say it is there. The description above mentions that it was merged in Infernalis.
