Show volume efficiency statistics

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

Description

The volume efficiency stat command displays efficiency statistics. This command is not supported on Infinite Volumes. The output depends on the parameters specified with the command. If no parameters are specified, the command displays the following efficiency statistics fields for all the volumes:

  • Vserver: The Vserver that the volume belongs to.

  • Volume Name: Name of the volume.

  • Inline Compression Attempts: Number of inline compression attempts done.

  • Inline Incompressible CGs: Number of compression groups that cannot be compressed by inline compression.

To display detailed information, run the command with -instance parameter.

Parameters
