The volume show-footprint command displays information about the space used in associated aggregates by volumes and features enabled in volumes. The command output depends on the parameter or parameters specified with the command. If no parameters are specified, the command displays the following information about all volumes. + + If the associated aggregates have an object-store attached to them, then the command displays a more detailed split up of the space used in each tier. This additional information is useful to show per-tier space usage which can be used to estimate the space requirements and transfer duration when moving a volume to a different tier with volume move .
