Ceph

Background in my case:

I would like to drain all ongoing scrubs because I wish to change "osd_deep_scrub_stride" and https://tracker.ceph.com/issues/58240 / https://github.com/ceph/ceph/commit/db8d185288d0e9602f654c89b7f18f8be45de3d0 suggests thta in my Ceph version, I should better first stop all ongoing scrubs.

But I think in general the fact that scrubbing cannot be drained looks like a bug.

There is also the tangentially related issue https://tracker.ceph.com/issues/11202 but that is about instanteneous stopping of scrubs, not draining.

I suspect that this is simply https://tracker.ceph.com/issues/54172#note-14

Feel free to close if this makes sense.
