Display volume inactive data compression progress

Availability: This command is available to cluster and Vserver administrators at the advanced privilege level.

Description

The volume efficiency inactive-data-compression show command is used to show details of inactive data compression on a volume.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.
