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 -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.

cluster1::> volume efficiency stat
Vserver:                       vs1
Volume:                        vol2
Inline Compression Attempts:   0
Inline Incompressible CGs:     0

Vserver:                       vs1
Volume:                        vol3
Inline Compression Attempts:   0
Inline Incompressible CGs:     0

At the diagnostic level, the output displays the information below.
