Symptoms

Consider the following scenario:
  • You enable the Cluster Shared Volumes (CSV) feature on a Windows Server 2012-based failover cluster.
  • You create a virtual machine on a CSV volume on a cluster node.
  • You start the virtual machine.
  • You try to create a backup of the virtual machine on the CSV volume by using Microsoft System Center Data Protection Manager (DPM).
In this scenario, one of the following issues occurs:
  • The backup is created, and the virtual machine enters a paused state.
  • The CSV volume goes offline. Therefore, the virtual machine goes offline, and the backup is not created.
Additionally, the following events are logged in the Cluster log and System log respectively:

Software snapshot creation on Cluster Shared Volume(s) ('volume location') with snapshot set id 'snapshot id' failed with error 'HrError(0x80042308)(2147754760)'. Please check the state of the CSV resources and the system events of the resource owner nodes.

Log Name: System
Source: Microsoft-Windows-FailoverClustering
Date: Date and time
Event ID: 5120
Task Category: Cluster Shared Volume
Level: Error
Keywords:
User: SYSTEM
Computer: Computer name
Description: Cluster Shared Volume 'Volume1' ('name’) is no longer available on this node because of 'STATUS_IO_TIMEOUT(c00000b5)'. All I/O will temporarily be queued until a path to the volume is reestablished.


Log Name: System
Source: Microsoft-Windows-FailoverClustering
Date: Date and time
Event ID: 5142
Task Category: Cluster Shared Volume
Level: Error
Keywords:
User: SYSTEM
Computer: Computer name
Description: Cluster Shared Volume 'Volume3' ('Cluster Disk 4') is no longer accessible from this cluster node because of error 'ERROR_TIMEOUT(1460)'. Please troubleshoot this node's connectivity to the storage device and network connectivity.


Note This issue also occurs when you try to create a snapshot of the virtual machine by using backup software that uses the Microsoft Software Shadow Copy Provider.

Additionally, the following behavior is also observed:
  • When an administrator starts a snapshot of a CSV volume, there may be an increase in the memory usage on the node owning the CSV resource. This corresponds to the number of bytes that are read from the snapshot volume by non-owning nodes. Installing this KB eliminates the increased memory usage.

Cause

The virtual machine enters a paused state because the Ntfs.sys driver incorrectly reports the available space on the CSV volume when the backup software tries to create a snapshot of the CSV volume. Additionally, the CSV volume goes offline because it does not resume from a paused state after an I/O delay issue or error occurs.

Note The CSV volume is resilient.

Resolution

Hotfix information

This hotfix prevents a CSV failover by fixing an underlying issue in NTFS and by increasing the overall resilience of the Cluster service and CSV during expected pause states.

To avoid CSV failovers, you may have to make additional changes to the computer after you install the hotfix. For example, you may be experiencing the issue described in the "Symptoms" section because of the lack of hardware support for Offloaded Data Transfer (ODX). This causes delays when the operating system queries for hardware support during I/O requests.

In this situation, disable ODX by changing the FilterSupportedFeaturesMode value for the storage device that does not support ODX to 1. For more information about how to disable ODX, go to the following Microsoft website:
General information about how to deploy ODX (http://technet.microsoft.com/en-us/library/jj200627)
