What logical space reporting shows

When you enable the logical space reporting feature in ONTAP, System Manager displays the amount of used and available space in addition to the total space on a volume.

When used, logical space reporting shows the following columns to users in System Manager:

The Total column, which shows the amount of used and available space, can appear greater than the provisioned space on the volume; this discrepancy occurs because the Total column includes any block savings achieved through deduplication, compression, and other space-saving capabilities.

Note: Beginning with ONTAP 9.4, logical space reporting is enabled by default.
