Update that improves cloud service provider resiliency in Windows Server 2012

Issue 1

Assume that you have a Windows Server 2012-based failover cluster. A cluster that uses Cluster Shared Volumes (CSV) is moved or is toggled between directed access and redirected access when the performance monitor is running. In this situation, the performance counters no longer function.

Issue 2

Consider the following scenario:

  • You have the Hyper-V server role installed on Windows Server 2012-based failover cluster nodes.
  • Virtual hard disk (VHD) files of the virtual machines are stored on a scale-out file share.
  • The server is under a heavy load.

In this scenario, the server may crash, and you may receive a Stop error message that resembles the following:

STOP: 0x000000C2 (parameter1, parameter2, parameter3, parameter4)


  • The parameters in the Stop error message vary, depending on the configuration of the computer.
  • Not all “Stop 0x000000C2” errors are caused by this issue.

Issue 3

When you use the Windows thin provisioning feature on a Windows Server 2012-based computer, you experience the same I/O delays or I/O stalls that occur during the volume-unmounting process. 

Note This issue occurs only on NTFS volumes.
