Title:
  When using LVM backed images the audit 'Total Disk' reports for system
  drive

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  When running nova with LVM backed instances, the 'Total Disk' usage
  audit doesn't report the usage of the instance VG

  In the case below it should report 4.5Tb not 629Gb.
  This could cause oversubscription of the backing VG.
