    Acc. to following KB article Clustered volumes are not supported by RevertToSnapshot  API - http://support.microsoft.com/kb/945361 on Windows 2003.
    Are clustered volumes not supported for Windows 2008 as well ?

    On a test setup of mine, revetToSnapshot is failing with volumes not supported. Here's a part of vss trace logs:

    Please confirm if case is also valid for Windows 2008.

    Thanks,
