[ceph-users] Active+clean PGs reported many times in log

Is this from a time when it was displaying the doubled active+clean
outputs? Otherwise you'll need to retrieve a specific map when it was.
I'll ask around if anybody's seen this before; Jewel has been out a
while and the pg output like this changed dramatically for Luminous so
it may not be an issue in the latest LTS.
