For nodes after first 3: reduce osd crush weight to 0 on node, weight for data to be moved ( see PG Status chart), once done shut down node then delete from node list

nodes 1-3 cannot be deleted, you can replace them with other hardware using "Replace Management Node", you can still remove their OSD using the first method
