volume efficiency undo

Undo efficiency on a volume

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

Description

Remove volume efficiency on a volume by undoing compression, removing all the block sharing relationships, and cleaning up any volume efficiency specific data structures. Any efficiency operations on the volume must be disabled before issuing this command. The volume efficiency configuration is deleted when the undo process completes. This command is not supported on Infinite Volumes that are managed by storage services.

Parameters

-vserver <vserver name> - Vserver Name

This specifies the Vserver on which the volume is located.

{  -volume <volume name> - Volume Name

This specifies the volume name.

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

This specifies the volume path.

[-compression | -C [true]] - Decompress The Data In The Volume

Undo the effects of compression. This requires efficiency to be disabled (by performing volume efficiency off).

[-dedupe | -D [true]] - Undo Block Sharing In The Volume

Undo the effects of deduplication. This requires efficiency to be disabled (by performing volume efficiency off).

[-inode | -i <integer>] - Inode Number To Undo Sharing

Remove the block sharings from a specified inode. This parameter is not supported on Infinite Volumes.

[-undo-type | -t {all|wrong}] - Selective Undo

This specifies to remove either all or only invalid block sharing. When all is used, all block sharings are removed. When wrong is used, only invalid sharings present in the volume are removed. When used along with log option, it logs information about all or wrong block sharings without sharing removal.

[-log | -d [true]] - Only Log Incorrect Savings

If true, information about invalid block sharing relationships will only be logged. Invalid sharings will not be removed. This option is only valid when the parameter undo-type is set to wrong.

Examples

The following are examples of how to use efficiency undo.
cluster1::> volume efficiency undo -vserver vs1 -volume vol1
cluster1::> volume efficiency undo -vserver vs1 -volume vol1 -compression true
cluster1::> volume efficiency undo -vserver vs1 -volume vol1 -dedup true -compression true
