Does Ceph rebalance OSDs proportionally

Hi all,

Quick qestion, does the Crush map always strive for proportionality when rebalancing a cluster? i.e. Say I have 8 OSDs (with a two node cluster - 4 OSDs per host - at ~90% utilization (which I know is bad, this is just hypothetical). Now if I add a total of 8 OSDs - 4 new OSDs for each host - will the crush map try to rebalance such that all disks have a utilization of 40-50%? Assumption being all disks are of equal size and weight.
