Yes, primary OSD. Extracted with grep -e scrub -e repair -e 19.1fff /var/log/ceph/ceph-osd.338.log and then only relevant lines copied.
Yes, according to the case I should just run a deep-scrub and should see. I guess if this error was cleared on an aborted repair, this would be a new bug? I will do a deep-scrub and report back.

About the restart, you should probably just deep-scrub again to see the current state. ..

As an alternative explanation, we had this scrub error, I started a repair but then OSDs in that PG were shut down and restarted. Is it possible that the repair was cancelled and the error cleared erroneously?

It reminds me of this bug - https://tracker.ceph.com/issues/52705 - where an object with a particular name would hash to ffffffff and cause a stat mismatch during scrub. But 15.2.17 should have the fix for that. Can you find the relevant osd log for more info? ..
