Enabling data compression on a volume

You can enable data compression only on FlexVol volumes that are contained within 64-bit aggregates. You can enable data compression to achieve space savings by using the sis config command.

Before you begin

You must have enabled deduplication on the volume.

About this task

You can enable both inline and postprocess compression or only postprocess compression on a volume. Before enabling inline compression, you must enable postprocess compression on the volume.

Step

  1. Enable data compression by entering the following command: sis config [-C {true|false}] | [-I {true|false}] | [-Q {true|false}] | [-z <file_size>] path

    true value for -C option enables postprocess compression.

    true value for -I option enables inline compression.

    true value for -Q option enables incompressible data detection.

    file size for -z option specifies the minimum file size to attempt quick check on a file.

    path is the complete path to the FlexVol volume.

Examples

The following command enables postprocess compression on the volume VolA: sis config -C true /vol/VolA

The following command enables both postprocess and inline compression on the volume VolA:sis config -C true -I true /vol/VolA
