Windows Server 2012 Failover Cluster and Hyper-V Hotfix List

Do you know this moment: Are all patches deployed by WSUS for my Cluster, or are this event log entries from a bug ?


Actual Hotfixes:

KB 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

v1 dont install: there are a lot of memory leaks reported
v2 intermediate version but not final: link for the new KB 2813630 but be aware of ODX and disable it if you need to ! There are still errors with v2
Please follow this forum link we expect a v3 stay tuned. "The Windows team is investigating other issues found during testing and not included in this release.  However they wanted to get this fix published since the memory leak issue is fixed and provide immediate relief"
v3  new release from Microsoft :Update that improves cluster resiliency in Windows Server 2012 is available will replace v2 (KB2813630) with v3 (KB 2838669)
v4 the KB2838669 was replaced with KB 2870270

One other thing to think about is that a LUN (CSV) created under Windows 2008R2 should not be used. Create a new LUN (CSV) with Windows Server 2012 (R2)

1. Open a Windows PowerShell session as an administrator.
2. Check whether ODX is currently enabled (it is by default) by verifying that the FilterSupportedFeaturesMode value in the registry equals 0. To do so, type the following command:
   Get-ItemProperty hklm:\system\currentcontrolset\control\filesystem -Name "FilterSupportedFeaturesMode"
3. Disable ODX support. To do so, type the following command
   Set-ItemProperty hklm:\system\currentcontrolset\control\filesystem -Name "FilterSupportedFeaturesMode" -Value 1
