Thanks I did apply https://github.com/ceph/ceph/pull/26179.
Running manual upmap commands work now. I did run "ceph balancer optimize new"and It did add a few upmaps. But now another issue. Distribution is far from perfect but the balancer can't find further optimization. Specifically OSD 23 is getting way more pg's than the other 3tb OSD's.
