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:

• Used: shows the total afs-physical-used space and savings in the volume
• Available: shows the amount of physical space currently available on the volume
• Logical Space Used (%): shows the percentage of current afs-logical-used with the provisioned size (excluding snap reserve of the volume)
• Logical Space: shows whether the logical space reporting feature is enabled
• Total: shows the amount of used and available space

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.
