Logical space reporting and enforcement for volumes

Beginning with ONTAP 9.5, you can allow the logical space used in a volume and the amount of remaining storage space to be displayed to users. Beginning with 9.5, you can limit the amount of logical space consumed by users.

Logical space reporting and enforcement are disabled by default.

The following volume types support logical space reporting and enforcement.

  • What logical space reporting shows
    When you enable logical space reporting on a volume, your system can display the amount of logical used and available space in addition to the total space in a volume. In addition, users on Linux and Windows client systems can see logical used and available space instead of physical used and physical available space.
  • What logical space enforcement does
    When you enable logical space enforcement in ONTAP 9.5 and later, ONTAP counts the logical-used blocks in a volume to determine the amount of space that is still available in that volume. If there is no space available in a volume, the system returns an ENOSPC (out-of-space) error message.
  • Enabling logical space reporting and enforcement
    Beginning with ONTAP 9.5, you can enable logical space reporting. Beginning with 9.5, you can enable logical space enforcement, or both reporting and enforcement together.
