Applies to

  • ONTAP 9
  • AFF/FAS systems

Answer

  • It is not possible to reduce a volume's size below the total amount of data it holds.
  • There will be an impact of snapshots and compression on the amount of space that can be reclaimed.
  • If thin provisioning is used, disable space reservation and run space reclamation to free up space.
