Good evening dear fellow Ceph'ers,
when removing OSDs from a cluster, we sometimes use
ceph osd reweight osd.XX 0
and wait until the OSD's content has been redistributed. However, when
then finally stopping and removing it, Ceph is again rebalancing.
I assume this is due to a position that is removed in the CRUSH map and
thus the logical placement is "wrong". (Am I wrong about that?)
I wonder, is there a way to tell ceph properly that a particular OSD is
planned to leave the cluster and to remove the data to the "correct new
position" instead of doing the rebalance dance twice?
Best regards,
Nico
