Introduction

This article introduces an update for cluster resiliency improvements in Windows Server 2012. After you install this update, the issues that are described in the following Microsoft Knowledge Base (KB) articles are resolved:
2801054 VSS_E_SNAPSHOT_SET_IN_PROGRESS error when you try to back up a virtual machine in Windows Server 2012
2796995 Offloaded Data Transfers fail on a computer that is running Windows 8 or Windows Server 2012
2813630 Virtual machine enters a paused state or a CSV volume goes offline when you try to create a backup of the virtual machine on a Windows Server 2012-based failover cluster
2824600 Virtual machine enters a paused state or goes offline when you try to create a backup of the virtual machine on a CSV volume in Windows Server 2012
2846618 I/O delays or I/O stalls in Windows Server 2012

2799728 Virtual machine enters a paused state or a CSV volume goes offline when you try to create a backup of the virtual machine on a Windows Server 2012-based failover cluster

Note This update replaces a previous resiliency improvements update that is described in KB article 2838669.

Additionally, the following issues that you experience are resolved.

Issue 1

Assume that you have a Windows Server 2012-based failover cluster. A Cluster Shared Volume (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 cluster nodes are under heavy loads.
In this scenario, the cluster nodes may crash, and you may receive a Stop error message that resembles the following:

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

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