Creating FlexVol volumes
You can create a FlexVol volume for your data by using the Create Volume dialog box. You should always create a volume for your data rather than storing data in the root volume.
Before you begin 
The storage system must contain a non-root aggregate. You cannot create traditional volumes through System Manager.
About this task 
You cannot enable data compression on a volume if you are using Data ONTAP-v storage.
Steps 
1.
From the home page, double-click the appropriate storage system.
2.
In the navigation pane, click Storage > Volumes.
3.
Click Create.
4.
If you want to change the default name, specify a new name.
5.
Select the containing aggregate for the volume.
If the containing aggregate is enabled for SnapLock compliance, the volume created has mandatory SnapLock protection.
6.
Select the type of storage for which you are creating this volume.
7.
Specify the size of the volume and the percentage of the total volume size that you want to reserve for Snapshot copies.
8.
If you want to enable thin provisioning for the volume, select Thin Provisioned.
When thin provisioning is enabled, space is allocated to the volume from the aggregate only when data is written to it.
9.
If you want to enable deduplication, compression, or both these features on this volume, make the necessary changes in the Storage Efficiency tab.
You cannot enable compression on a 32-bit volume.
System Manager uses the default deduplication schedule. If the specified volume size exceeds the limit required for running deduplication, the volume is created and deduplication is not enabled.
10.
Click Create.
11.
Verify that the volume you created is included in the list of volumes in the Volume window.
The volume is created with UNIX style security and UNIX 700 "read write execute" permissions for the Owner.
