Enabling storage efficiency on a FlexGroup volume

You can run deduplication and data compression together or independently on a FlexGroup volume to achieve optimal space savings.

1. Enable storage efficiency on the FlexGroup volume: volume efficiency on -vserver svm_name -volume volume_name

   Storage efficiency operations are enabled on all the constituents of the FlexGroup volume.

   If a FlexGroup volume is expanded after storage efficiency is enabled on the volume, storage efficiency is automatically enabled on the new constituents.

2. Enable the required storage efficiency operation on the FlexGroup volume by using the volume efficiency modify command.

   You can enable inline deduplication, postprocess deduplication, inline compression, and postprocess compression on FlexGroup volumes. You can also set the type of compression (secondary or adaptive) and specify a schedule or efficiency policy for the FlexGroup volume.

3. If you are not using schedules or efficiency policies for running the storage efficiency operations, start the efficiency operation: volume efficiency start -vserver svm_name -volume volume_name

   If deduplication and data compression are enabled on a volume, data compression is run initially followed by deduplication. This command fails if any efficiency operation is already active on the FlexGroup volume.
4. Verify the efficiency operations that are enabled on the FlexGroup volume: volume efficiency show -vserver svm_name -volume volume_name

   Example

   cluster1::> volume efficiency show -vserver vs1 -volume fg1
                Vserver Name: vs1                       
                 Volume Name: fg1                   
                 Volume Path: /vol/fg1              
                       State: Enabled
