Hi all,
Just checking if someone had a chance to go through the scrub trigger issue above. Thanks.

Hi all,
I am trying to trigger deep scrubbing in Ceph reef (18.2.0) on demand on a set of files that I randomly write to CephFS. I have tried both invoking deep-scrub on CephFS using ceph tell and just deep scrubbing a particular PG. Unfortunately, none of that seems to be working for me. I am monitoring the ceph status output, it never shows any scrubbing information. Can anyone please help me out on this ? In a nutshell, I need Ceph to scrub for me anytime I want. I am using Ceph with default configs for scrubbing. Thanks all.
