Answer

  • The "Extended Compressed Data" field indicates whether extended compressed data is present on the volume.
  • This field shows `true` when both adaptive compression configured with an application IO size of 8K and data compaction are enabled.

Additional Information

To enable extended compressed data, ensure that both adaptive compression and data compaction are configured correctly.

  • Use the following command to check the current efficiency settings of the volume:

::> volume efficiency show -instance

Look for the fields `Storage Efficiency Mode` and `Data Compaction`.

  • Enable adaptive compression and data compaction using the following commands:

::> volume efficiency modify -vserver <vserver_name> -volume <volume_name> -storage-efficiency-mode efficient

::> volume efficiency modify -vserver <vserver_name> -volume <volume_name> -data-compaction true
