RevertToSnapshot for Clustered volume

Wed, 01 Jul 2009 07:32:11 Z

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.

Hi Ashish,

AFAIK, Cluster volume should be also support on Windows Server 2008.

Thanks and Regards,

Thanks for reply Scorpio.

Looks like a bug in Windows Server 2008 in that case.
