A volume that is loosely coupled to its containing aggregate. A FlexVol volume can share its containing aggregate with other FlexVol volumes. Thus, a single aggregate can be the shared source of all the storage used by all the
FlexVol volumes contained by that aggregate.
You can use FlexVol volumes to organize and manage system and user data. A volume can hold qtrees and LUNs.
After you set up the underlying aggregate, you can create, clone, or resize FlexVol volumes without regard to the underlying physical storage. You do not have to manipulate the aggregate frequently.
