crush: command to set additional parents for an interior node or leaf
Currently you can have an OSD is multiple roots, but you need to generate the crushmap manually to do so.
Request is to allow the cli to take in multiple roots, for example.
ceph osd crush set osd.X root=default host=node1 root=zone1 host=node1

i think this will make more sense as a command to explicitly add a second link to the bucket/whatever that has multiple parents.. similar to how the 'move' command is needed to move interior nodes around the tree
