Doc Text:	.Scrubbing is blocked for any PG if the primary or any replica OSDs are recovering The `osd_scrub_during_recovery` parameter now defaults to `false`, so that when an OSD is recovering, the scrubbing process is not initialized on it. Previously, `osd_scrub_during_recovery` was set to `true` by default allowing scrubbing and recovery to run simultaneously. In addition, in previous releases if the user set `osd_scrub_during_recovery` to `false`, only the primary OSD was checked for recovery activity.	Story Points:	---

We're going to need this applied downstream Vikhyat. Would you please let me know when that will be ready?

Thanks Gregory. I just checked upstream PR - https://github.com/ceph/ceph/pull/17815 It is under Kefu testing branch and I think as soon as upstream testing will complete. David should be able to take it downstream.

I am changing the needinfo to David.

Comment 7 Ian Colle 2017-10-04 15:48:56 UTC

Kefu,

When do you think https://github.com/ceph/ceph/labels/wip-kefu-testing will be merged?

Comment 13 David Zafman 2017-10-11 20:40:04 UTC

Ken: To test this change you need to include https://bugzilla.redhat.com/show_bug.cgi?id=1482749 or set osd_scrub_during_recovery false.
