      Description

      In one example:
      Cluster Summary
      Capacity : 1.15 PB
      DFS Remaining : 192 TB
      DFS Used : 717 TB
      DFS Used% : 62 %

      Why is Capacity not equal Used plus Remaining?

      (The answer is that there is an estimated reserve for local files.)

      The presentation should be easily understood by the user.
