The volume efficiency show command displays the information about storage efficiency of volumes. The command output depends on the parameter or parameters specified. If no parameters are specified, the command displays the following information for all volumes with efficiency:

Vserver: Vserver the volume belongs to.
Volume: Name of the volume.
State: Current state of efficiency on the volume (Enabled, Disabled, or Mixed).
Status: Status of the efficiency on the volume. Following are the possible values:
Active : An efficiency operation is currently running.
Idle : There are no efficiency operations running.
Initializing : An efficiency operation is being initialized.
Undoing : Efficiency is being undone on the volume.
Pending : An efficiency operation is queued.
Downgrading : An efficiency operation necessary to downgrade the efficiency metafiles to a previous ONTAP release is active.
Disabled : Efficiency is disabled on the volume.
Progress: The progress of the current efficiency operation with information as to which stage of the efficiency process is currently in progress and how much data is processed for that stage. For example: "25 MB Scanned", "20 MB Searched", "500 KB (2%) Compressed", "40 MB (20%) Done", "30 MB Verified".

To display detailed information, run the command with the ` -l ` or -instance parameter. The detailed view provides all information in the previous list and the following additional information:

Path: Volume Path.
Compression: Current state of compression on the volume (Enabled or Disabled).
Inline Compression: Current state of inline compression on the volume (Enabled or Disabled).
Type: Type of volume (Regular or SnapVault).
Schedule: The schedule of efficiency operation for the volume.
Policy: Efficiency policy for the volume.
Minimum Blocks Shared: The minimum number of adjacent blocks in a file that can be shared.
Blocks Skipped Sharing: Blocks skipped sharing because of the minimum block share value.
Last Operation State: Status of the last operation (Success or Failure).
Last Successful Operation Begin: The time and date at which the last successful operation began.
Last Successful Operation End: The time and date at which the last successful operation ended.
Last Operation Begin: The time and date at which the last operation began.
Last Operation End: The time and date at which the last operation ended.
Last Operation Size: The size of the last operation.
Last Operation Error: The error encountered by the last operation.
Change Log Usage: The percentage of the change log that is used.
Logical Data: The total logical data in the volume, and how much is reached compared to the deduplication logical data limit.
Queued Job: The job that is queued. Following are the possible values:
- : There are no queued jobs.
scan : A job to process existing data is queued.
start : A job to process newly added data is queued.
check : A job to eliminate stale data from the fingerprint database is queued.
downgrading : An efficiency operation necessary to downgrade the efficiency metafiles to a previous ONTAP release is queued.
Stale Fingerprints: The percentage of stale entries in the fingerprint database. If this is greater than 20 percent a subsequent volume efficiency start operation triggers the verify operation, which might take a long time to complete.
Inline Dedupe: Current state of inline deduplication on the volume (Enabled or Disabled).
Cross Volume Inline Deduplication: Current state of cross volume inline deduplication on the volume (Enabled or Disabled).
Cross Volume Background Deduplication: Current state of cross volume background deduplication on the volume (Enabled or Disabled).
Extended Compressed Data: Is there extended compressed data present on the volume.
Inline Adaptive Data Compaction: Whether Inline Adaptive Data Compaction is enabled or disabled on the volume. When enabled, ONTAP combines data fragments to reduce on-disk block consumption.

You can specify additional parameters to display information that matches only those parameters. For example, to display information only about volumes with efficiency in Vserver vs1, run the command with the -vserver vs1 parameter.
