volume efficiency stat

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:

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

Parameters

{  [-fields <fieldname>, ...]

This specifies the fields that need to be displayed. The Vserver and volume name are the default fields.

|  [-instance ]  }

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

[-vserver <vserver name>] - Vserver Name

Displays statistics only for those volume(s) that match the specified Vserver.

{  [-volume <volume name>] - Volume Name

Displays statistics only for those volume(s) that match the specified volume name.

|  [-path </vol/volume>]  } - Volume Path

Displays statistics only for those volume(s) that match the specified volume path.

[-b [true]] - Display In Blocks

Displays usage size in 4k block counts.

[-num-compressed-inline <integer>] - Inline Compression Attempts

Displays statistics only for those volume(s) that match the specified number of Compression Groups attempted inline.

Examples

The following example displays default efficiency statistics for all the volumes.
