The problem is you have size=2 and min_size=2 on this pool. I would increase the size of this pool to 3 (but i would also do that to all of your pools which are size=2) the ok-to-stop command is failing because you would drop below min_size by stopping any osd service this pg and those pgs would then be inactive.

Thank you. Having size>min_size for all pools solved this (all OSDs became ok-to-stop and upgrade to 16.2.8 completed).
