Reducing the size of a FlexGroup volume

Starting with ONTAP 9.6, you can resize a FlexGroup volume to a value lower than its current size to free up the unused space from the volume. When you reduce the size of a FlexGroup volume, ONTAP automatically resizes all of the FlexGroup constituents.

Procedure

Reduce the size of the FlexGroup volume: volume size -vserver vserver_name -volume fg_name -size new_size
new_size is the size of the FlexGroup volume. You can either specify a lower value than the current size or a negative value by which the current size of the FlexGroup volume is reduced.
Note: If automatic shrinking is enabled for the volume (volume autosize command), the minimum autosize is set to the new size of the volume.
