Managing SIS on a Volume

  • Article

Applies To: Windows Storage Server 2008 R2

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

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

Note

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

Local Administrators permissions are required to complete the following procedures.

To enable SIS on a volume

  1. Click Start, point to Administrative Tools, and then click Share and Storage Management.

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

  3. In the Actions pane, click Properties.

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

To disable SIS on a volume

Using Sisadmin.exe

Every time you enable or disable SIS on a volume, the Groveler service restarts. To avoid performance issues when enabling or disabling SIS on a large number of volumes, use the Sisadmin.exe utility to specify them all in a single command. Grouping all the volumes with a single command requires only a single restart of the Groveler service.
