k, in the past we used the python crush optimize tool to reweight the osd usage - it inserted a 2nd tree with $hostname-target-weight as hostnames. Now the quesions are: 1.) can we remove the tree? How? 2.) Can we do this now or only after all clients are running Luminous? 3.) is it enought to enable the mgr balancer module? Thanks!
