You can view details about space usage in a volume to understand which Data ONTAP features are consuming space and what you can do to decrease that used space. The vol status -S command displays the space used by each of the file system components as well as other features. The vol status -S command includes offline volumes. For example, you might want to understand why the df command output shows that a large amount of space is still used even though you deleted all of your data in a volume. In this case, output for the volume space usage command might show that it is due to Snapshot copies, inodes, or other metadata that does not shrink. Only non-zero values are displayed in the command output. However, you can use the -v 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 tables explain some of the common rows in the vol status -S command output and what you can do to try to decrease space usage by that feature: The output for this command consists of the following main categories:
For information about how to reduce space consumed by other features (such as deduplication), see the respective Data ONTAP guides. The available space in a volume with a guarantee type of None is limited by the available space in the aggregate. Checking the available space in the aggregate might show you that the aggregate is nearly full from aggregate Snapshot copies. The following output row relates to user data:
The following output rows relate to volume metadata:
The following output rows relate to Snapshot copies:
The following row relates to total used space in the volume:
