Thank you, Eugen.
Indeed it looks like the progress module had some stale events from the
time when we added new OSDs and set a specific number of PGs for pools,
while the autoscaler tried to scale them down. Somehow the scale-down
events got stuck in the progress log, although these tasks have finished a
long time ago. Failing over to another MGR didn't help, so I have cleared
the progress log.
I also restarted both mgrs, but unfortunately the warnings are still being
logged.
