Answer

  • The difference in usage values is because of the difference in methods followed by the quota report and the UNIX commands for calculating the data blocks in the volume or qtree.
  • For example, if a volume contains a file that has empty data blocks,the quota report for the volume does not count the empty data blocks while reporting the space usage. However, when the volume is mounted on a UNIX client and the file is shown as the output of the ls command, the empty data blocks are also included in the space usage. Therefore, the ls command displays a higher file size when compared to the space usage displayed by the quota report.
