To list the cluster's keys and their capabilities, execute the following::

Move an existing bucket from one position in the hierarchy to another. ::

Mark an OSD as lost. This may result in permanent data loss. Use with caution. ::

Set or clear the pause flags in the OSD map. If set, no IO requests
will be sent to any OSD. Clearing the flags via unpause results in
resending pending requests. ::

right. For instance, if one of your OSDs is at 90% and the others are
at 50%, you could reduce this weight to try and compensate for it. ::
