Hey,
I have a cluster of 30 OSD's that is near perfect distribution minus two OSD's.
I am running ceph version 14.2.6 however has been the same for the previous versions, I have the balance module enabled in upmap and it says no improvements, I have also tried in crush mode.

I have read a few email threads on the ML recently about similar cases but not sure if I am hitting the same "bug" as its only two that are off the rest are almost perfect.

OSD 7,8 are the issue OSD's sitting at 182,187 PG's where the others are all sitting at 170,171.
Am I hitting the same issue? Or is there something I can do to re balance these extra PG's across the rest of the OSD better?
Thanks
