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 total of all volume footprints within the aggregate. It includes all of the space that is used or reserved by all data and metadata of all volumes in the containing aggregate. It is also the amount of space that is freed if all volumes in the containing aggregate are destroyed. Infinite Volume constituents appear in the output of space usage commands as if the constituents were FlexVol volumes.
The total file system metadata required by the aggregate, such as allocation bitmaps and inode files.
The amount of space reserved for aggregate Snapshot copies, based on volume size. It is considered used space and is not available to volume or aggregate data or metadata.
The amount of space originally allocated for aggregate Snapshot reserve that is unavailable for aggregate Snapshot copies because it is being used by volumes associated with the aggregate. Can occur only for aggregates with a non-zero aggregate Snapshot reserve.
The sum of all space used or reserved in the aggregate by volumes, metadata, or Snapshot copies.
The amount of space being used for data now (rather than being reserved for future use). Includes space used by aggregate Snapshot copies.
There is never a row for Snapshot spill.
The following example shows the aggregate show-space command output for an aggregate whose Snapshot reserve is 5%. If the Snapshot reserve was 0, the row would not be displayed.
