You try to extend a dynamic volume in the NTFS file system on a computer that is running Windows Vista, Windows Server 2008, Windows Server 2008 R2, or Windows 7. However, the volume extending operation fails. Additionally, the Virtual Disk Service (VDS) crashes.

For example, the issue occurs when you use the Diskpart.exe utility or the Symantec Storage Foundation for Windows to extend a dynamic volume.

Note for developers

When you call the Extend function of the IID_IVdsVolume interface to extend a dynamic volume, the operation fails together with the following error message:

error code 0×800706b
RPC_S_CALL_FAILED
