Chapter 16. Check CRUSH Hierarchy

Check your work to ensure that the CRUSH hierarchy is accurate.

ceph osd tree

If you are not satisfied with the results of your CRUSH hierarchy, you may move any component of your hierarchy with the move command.

ceph osd crush move <bucket-to-move> <bucket-type>=<parent-bucket>

If you want to remove a bucket (node) or OSD (leaf) from the CRUSH hierarchy, use the remove command:

ceph osd crush remove <bucket-name>
