Scrub while cluster re-balancing

Hi all,

I was running scrub while cluster is in re-balancing state.
From the osd logs..

Interestingly, for pg's 2.x (2.4, 2.9 etc)in logs here, cluster status was not reporting scrubbing, whereas for 0.x & 1.x it was reporting as scrubbing in cluster status.

In case of scrub operation on PG's (2.x) is really scrubbing performed OR cluster status is missing to report them?
