How to determine space usage in an aggregate

You can view space usage by all volumes in one or more aggregates with the aggregate show-space command. This helps you see which volumes are consuming the most space in their containing aggregates so that you can take actions to free more space.

The used space in an aggregate is directly affected by the space used in the FlexVol volumes and Infinite Volume constituents it contains. Measures that you take to increase space in a volume also affect space in the aggregate.

When the aggregate is offline, no values are displayed. Only non-zero values are displayed in the command output. However, you can use the -instance parameter to display all possible feature rows regardless of whether they are enabled and using any space. A value of - indicates that there is no data available to display.

The following rows are included in the aggregate show-space command output:

There is never a row for Snapshot spill.

The following example shows the aggregate show-space command output for an aggregate whose Snapshot reserve was increased to 5%. If the Snapshot reserve was 0, the row would not be displayed.
