A while ago - before ceph balancer - probably on Jewel
We had a bunch of disks with different re-weights to help control pg
We upgraded to luminous
All our disks are the same, so we set them all back to 1.0 then let them fill

I'm running a Ceph Mimic cluster 13.2.6 and we use the ceph-balancer
in upmap mode. This cluster is fairly old and pre-Mimic we used to set
osd reweights to balance the standard deviation of the cluster. Since
moving to Mimic about 9 months ago I enabled the ce
