When a new host or disk is added to a Ceph cluster, CRUSH starts a rebalancing operation, under which it moves the data from existing hosts/disks to a new host/ disk. Rebalancing is performed to keep all disks equally utilized, which improves the cluster performance and keeps it healthy. Internal Notes
