Description
https://ceph.com/docs/master/rados/operations/add-or-rm-osds/#adding-osds gives the following command for adding an OSD to the CRUSH map:
ceph osd crush add {id-or-name} {weight} [{bucket-type}={bucket-name} ...]</pre
This gives users the impression that all buckets are optional, but in any standard cluster configuration you must specify the "host" bucket or the OSD won't be used to store data. Make this clearer so it's less likely to be misused.
