Viewing efficiency space savings on a FlexVol volume

You can view the amount of space savings achieved through deduplication and data compression on a volume by using the df -S command.

About this task

The space savings in Snapshot copies are not included when calculating the space savings achieved on a volume. Using deduplication does not affect volume quotas. Quotas are reported at the logical level, and remain unchanged.

Step

View the space savings achieved on a volume using deduplication and data compression by entering the following command:df -S path
path is the complete path to the volume.

Example

The following command enables you to view the space savings achieved by using deduplication and data compression on volume VolA: df -S /vol/VolA

node1> df -S /vol/VolA
