> Given a cluster with X TB of ozone-used capacity out of a total of Y TB, the requirement is to break down the X TB of used capacity. The following are some of the ways this X TB of capacity could be utilized:
>  * OM-referred spaces: space occupied by actual FSO and OBS keys
>  * Space occupied by open keys/open files
>  * Delete-occupied space (in-progress) on OM side 
>  * Delete-occupied space (in-progress) on SCM side 
>  * Delete-occupied space (in-progress) on DN side
>  * Apart from this, the remaining space may be attributed to orphan blocks or any other space used for book-keeping purposes.
> We need to provide the user with a detailed breakdown (above mentioned categories) of the ozone-used capacity that adds up to the total ozone-used capacity as seen from the storage reports:
