Description

From Corin Langosch - During recovery/ rebalacing it can happen that an osd receives lots of new data before data that should be moved to other nodes is removed. This can (and did for me) result in overloading an osd which was only filled around 60% before rebalancing started. I think ceph should take the disk usage of the osds into account when deciding in which order the rebalancing of the objects should happen (move data from full osds away first and only then copy new data to them).
