What logical space reporting shows

When you enable the logical space reporting feature in ONTAP, System Manager displays the amount of logical 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 can be greater than the provisioned space on the volume; this discrepancy occurs because the Total column includes any block savings achieved through duplication, compression, and other space-saving capabilities.

The Logical Space Used (%) column can be greater than 100%, as afs-logical-used includes savings of the volume. The afs-logical-used space of a volume does not include snap spill as used space. The afs-physical-used space of a volume includes snap spill as used space.


Logical Space Reporting is disabled by default.
