That explains why I found nothing in the release notes of 12.2.2 :) 
Thanks a lot for pointing that out.

Using mon_max_pg_per_osd = 300 does work and now HEALTH is ok in this
cluster. Anyway I will move data to pools with less PGs asap, because
this cluster was supposed to have a few more OSDs that it will finally
have and the current PGs are suboptimal.

Thanks a lot to everyone.
