Updates volume inactive data reallocation policy

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

Description

The volume efficiency inactive-data-reallocation modify command is used to modify the inactive data reallocation policy on a volume.

Parameters

-vserver <vserver name> - Vserver Name (privilege: advanced)

This specifies the Vserver of the volume.

-volume <volume name> - Volume Name (privilege: advanced)

This specifies the volume on which the inactive data compression state should be modified.

[-policy {none|default|on-read|all}] - Policy for Data Reallocation (privilege: advanced)

This specifies policy for inactive data reallocation on the volume. Inactive to active data reallocation is not supported on QAT supported platforms.

Following are the possible values:

  • default : Reallocates data for random client driven data reads on AFS.

  • none : Disables inactive to active data reallocation.

  • on-read : Reallocates data for client driven data reads including sequential reads on AFS.

Currently unsupported policy:

  • all : Reallocates data for all client driven data reads on AFS and snapshots. Also includes highly compressed data which was compressed to one single 4k block.

Examples

The following example displays information for modifying the inactive data reallocation policy on volume "vol1":
