[jira] [Created] (HDDS-13177) Storage Capacity Distribution

Priyesh K created HDDS-13177:
--------------------------------

             Summary: Storage Capacity Distribution
                 Key: HDDS-13177
                 URL: https://issues.apache.org/jira/browse/HDDS-13177
             Project: Apache Ozone
          Issue Type: New Feature
            Reporter: Priyesh K


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:
