Configuring automatic free space preservation for a FlexVol volume

When you configure a FlexVol volume for automatic free space preservation, the FlexVol volume attempts to provide more free space when it becomes nearly full. It can provide more free space by increasing its size or by deleting Snapshot copies, depending on how you have configured the volume.

Step

1. Enter the following command:vol options vol-name try_first [volume_grow|snap_delete]

   If you specify volume_grow, Data ONTAP attempts to increase the volume's size before deleting any Snapshot copies. Data ONTAP increases the volume size based on specifications you provided using the vol autosize command.

   If you specify snap_delete, Data ONTAP attempts to create more free space by deleting Snapshot copies, before increasing the size of the volume. Data ONTAP deletes Snapshot copies based on the specifications you provided using the snap autodelete command.
