Enabling or Disabling SIS on a Volume

Published: July 10, 2009

Applies To: Windows Storage Server 2008

Single Instance Storage (SIS) is enabled or disabled on individual volumes on your storage appliance. When you disable SIS on a volume that has been using SIS, the Groveler service is stopped. SIS can be paused or disabled temporarily by pausing the Groveler service or changing its priority by using the Sisadmin.exe utility.

Once the Groveler service has been paused for a volume, SIS can be removed from that volume using the Sisadmin.exe utility. When SIS is removed from a volume, the files are unlinked from the SIS Common Store and restored to their original locations

noteNote
Disabling SIS on a volume will fail if there is not sufficient disk space on the volume to account for each duplicate file and the SIS Common Store.

Membership in the local Administrators group is required to complete this procedure. 

To enable SIS on a volume

  1. In Share and Storage Management, on the Volumes tab, click the volume for which you want to enable SIS.

  2. In the Actions pane, click Properties.

  3. On the Advanced tab, select the Enable SIS on this volume check box, and then click OK.

To disable SIS on a volume

  1. In Share and Storage Management, on the Volumes tab, click the volume for which you want to disable SIS.

  2. In the Actions pane, click Properties.

  3. On the Advanced tab, clear the Enable SIS on this volume check box, and then click OK.

noteNote
Every time you enable or disable SIS on a volume, the Groveler service is restarted. To avoid performance issues when enabling or disabling SIS on a large number of volumes, specify them all in a single command. Grouping the volumes into a single command requires only a single restart of the Groveler service.
