You can create FlexVol volumes, clone them, determine the amount of space they use, resize them, and display their containing aggregate, among other tasks.
Creating a FlexVol volume
You create FlexVol volumes to provide resizable, flexible data containers that can be mounted and accessed using all data access protocols supported by Data ONTAP.
Resizing a FlexVol volume
You can increase or decrease the amount of space that an existing FlexVol volume is allowed to occupy in its containing aggregate. A FlexVol volume can grow to the size you specify as long as the containing aggregate has enough free space to accommodate that growth.
