Hi,

 

I need to install patch KB5034439 on Windows servers

https://support.microsoft.com/en-us/topic/kb5034439-windows-recovery-environment-update-for-windows-server-2022-january-9-2024-6f9d26e6-784c-4503-a3c6-0beedda443ca

 

I have installed this type of patch on many servers using this Microsoft method.

https://support.microsoft.com/en-us/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf

 

However, using this method, I cannot install the patch on a Hyper-V cluster (S2D cluster) because it is not possible to shrink the primary partition(dynamic) and expand the recovery partition.

"This operation is only supported on simple or spanned volumes"

Is it possible to install the KB5034439 patch on an S2D cluster?

Thank you

    Hi Admin,

    Hope you're doing well.

    1. The method you mentioned involves manually resizing the partition to create enough space for the update. However, as you've rightly pointed out, this approach doesn't work for dynamic volumes. Unfortunately, this means you won't be able to use this method for your S2D cluster.
    2. Since shrinking dynamic volumes isn't supported, consider an alternative approach:

    (1) Apply the Windows Server Cumulative Update and any required Servicing Stack Updates to each node in the cluster. You can update all nodes simultaneously (no need to wait since the cluster is down). After updating, restart the nodes and verify everything looks good.

    (2) Ensure that the Cluster Service is set to Automatic on each node.

    1. If you encounter issues during patch installation, you can use the Deployment Image Servicing and Management (DISM) and System File Checker (SFC) tools to repair any corrupted system files. Open Command Prompt as an administrator and run the following:

    DISM /Online /Cleanup-Image /RestoreHealth

    This may help resolve any underlying issues that prevent successful patch installation.

    Remember to back up critical data and create a restore point before making any changes.

    Best Regards,

    Ian Xue

    Thanks Ian Xue,

    Both NODs in the cluster are up to date.Only the KB5034439 patch is not installed.

    My question was how to install the KB5034439 patch.All other CUs and security patches are installed except KB5034439.

    Thank you

    Regards
