Running deduplication on existing data

You can manually scan and eliminate duplicate blocks on an existing FlexVol volume.

Step

1. To start deduplication operations, enter the following command:sis start -s path

   path is the complete path to the FlexVol volume. For example, /vol/vol1. See the sis(1) man pages for more information.

   Note: If deduplication operations are already running on the volume when you run the sis start -s command (for example, if a scheduled deduplication operation has begun), the command will fail. To eliminate duplicate blocks that existed before the previous operation, run this command after the previous deduplication operation completes.
