26063 deduplication data corruption is still there.
From Server 2022 up to this newest 26063 build, they all have the same problem, as described here: https://techcommunity.microsoft.com/t5/windows-server-insiders/server-vnext-26040-and-server-2022-deduplication-data-corruption/m-p/4047321 I am out of energy for today and give up for today. It seems to be impossible to get Microsoft to care for actual OS bugs instead of marketing.
S2D FaultDomainAwareness
We're setting up a 2 Node windows 2025 cluster with storage spaces direct After creating the pool we created two virtual disk but see the following output PS C:\WINDOWS\system32> Get-VirtualDisk | Format-List FriendlyName, Size, FaultDomainAwareness FriendlyName : ClusterPerformanceHistory Size : 25769803776 FaultDomainAwareness : StorageScaleUnit FriendlyName : S2DVOL01 Size : 10995116277760 FaultDomainAwareness : FriendlyName : S2DVOL02 Size : 10995116277760 FaultDomainAwareness : The FaultDomainAwareness is empty for the two virtual disk created on the storage pool which is configured like this PS C:\WINDOWS\system32> Get-StoragePool –FriendlyName S2D-CLHV-001-Pool | Format-List FriendlyName, Size, FaultDomainAwarenessDefault FriendlyName : S2D-CLHV-001-Pool Size : 57592038555648 FaultDomainAwarenessDefault : StorageScaleUnit is there something wrong ?Allow for the expansion of physical disks in a storage pool
Allow for the expansion of physical disks in a storage pool just like lvm on Linux. This would be useful in virtual environments and in Azure to be able to expand the physical representation of the virtual disk file. Be it a vmdk or vhdx. This currently allowable on other modern logical volume managers out there. This should be trivial to modify since the meta data is already there. It could be added to the powershell commandlets to rescan-physicaldisk, which would rebuild the metadata on the pool. I have a feedback hub suggestion open on it, which if you could please upvote: https://aka.ms/AAy4ihwvNVMe on Hyper-V to unlock PCIe 5.0 NVMe performance
On hosts with NVMe PCIe 5.0 (E3.S/U.2), Hyper-V guests still use virtual SCSI and leave a lot of performance on the table. We are paying for top-tier storage, yet software becomes the limiter. A virtual NVMe device that preserves checkpoints/Replica/Live Migration would align guest performance with modern hardware without forcing DDA and its operational trade-offs.
Announcing Windows Server vNext Preview Build 26445
Announcing Windows Server vNext Preview Build 26445 Hello Windows Server Insiders! Today we are pleased to release a new build of the next Windows Server Long-Term Servicing Channel (LTSC) Preview that contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions, Annual Channel for Container Host and Azure Edition (for VM evaluation only). Branding remains, Windows Server 2025, in this preview - when reporting issues please refer to Windows Server vNext preview. If you signed up for Server Flighting, you should receive this new build automatically. What's New [NEW] Rack Level Nested Mirror (RLNM) for S2D Campus Cluster Rack Level Nested Mirror (RLNM) for S2D Campus Cluster enables customers to meet NIS2 two data room requirements for their factories by providing fast and resilient storage using Storage Spaces Direct (S2D). For S2D Campus Cluster, we recommend using all-flash storage (SSD or NVMe drives), all capacity (no cache drives), and RDMA NICs (iWARP, RoCE, or InfiniBand). Note: Rack fault domains must be created on the cluster in order to use this feature – a new cluster must be created: #Create a test cluster but do not create storage: New-Cluster -Name TestCluster -Node Node1, Node2, Node3, Node4 -NoStorage #Define the fault domains for the cluster – two nodes are in “Room1” and two nodes are in “Room2”: Set-ClusterFaultDomain -XML @”<Topology><Site Name=”Redmond”><Rack Name=”Room1”><Node Name=”Node1”/><Node Name=”Node2”/></Rack><Rack Name=”Room2”><Node Name=”Node3”/> <Node Name=”Node4”/></Rack></Site></Topology>”@ #Add Storage Spaces Direct (S2D) Storage to the cluster – note that Enable-ClusterS2D cmdlet can also be used: Enable-ClusterStorageSpacesDirect #Update the Storage Pool Update-StoragePool #Check that the StoragePool version is 29: (Get-CimInstance -Namespace root/microsoft/windows/storage -ClassName MSFT_StoragePool -Filter 'IsPrimordial = false').CimInstanceProperties['Version'].Value #Check that the Storage Pool’s FaultDomainAwareness property is set to StorageRack: Get-storagepool -FriendlyName <S2DStoragePool> | fl #Note that resiliency is specified when the volume is created – our idea with the S2D Campus cluster is that customers can create both four-copy and two-copy volumes - valuable workload (VMs) and data should go on the 4-copy volumes. #Create a four-copy volume on the storage pool, fixed provisioned: New-Volume -FriendlyName “FourCopyVolumeFixed” -StoragePoolFriendlyName S2D* -FileSystem CSVFS_ReFS –Size 500GB -ResiliencySettingName Mirror -PhysicalDiskRedundancy 3 -ProvisioningType Fixed -NumberOfDataCopies 4 –NumberOfColumns 3 #Optional - Create a four-copy volume on the storage pool, thinly provisioned: New-Volume -FriendlyName “FourCopyVolumeThin” -StoragePoolFriendlyName S2D* -FileSystem CSVFS_ReFS –Size 500GB -ResiliencySettingName Mirror -PhysicalDiskRedundancy 3 –ProvisioningType Thin -NumberOfDataCopies 4 –NumberOfColumns 3 #Optional - Create a two-copy volume on the storage pool, fixed provisioned: New-Volume -FriendlyName “TwoCopyVolumeFixed” -StoragePoolFriendlyName S2D* -FileSystem CSVFS_ReFS –Size 500GB -ResiliencySettingName Mirror -PhysicalDiskRedundancy 1 -ProvisioningType Fixed #Optional - Create a two-copy volume on the storage pool, thinly provisioned: New-Volume -FriendlyName “TwoCopyVolumeThin” -StoragePoolFriendlyName S2D* -FileSystem CSVFS_ReFS –Size 500GB -ResiliencySettingName Mirror -PhysicalDiskRedundancy 1 -ProvisioningType Thin Windows Server Flighting is here!!

Server 2022, network drives and content searching
We have two drives with close to 1TB of data, The one drive has a specific folder where end users want to search for a file using content from the files. The files are generally .xls based files End users are 99% Windows 11 based and server is server 2022. Indexing on the server with content aware filtering has occurred and can find the files when searching for their names however not when searching content. This needs to happen using Windows Search in explorer. Data is unstructured, however structured in a folder system. (Year, month, etc) I have read that Windows Content Search is not supported on network drives, can this be confirmed? Any suggestions on a resolution would be appreciated.
Issue with existing drive formatted to ReFS and mounting in new server
I had a hardware failure which also took out my Server installation drive. I have new hardware and have installed Server 2022 again on new drive. I have connected a drive that I had formatted as ReFS and now it shows as RAW and Event log shows "ReFS failed to mount the volume. Version 3.14 doesn't match expected value 3.7" I have no idea what is going on here. Both installations of Server 2022 used the same media. This is getting very painful. I have connected the drive to a Windows 11 24H2 computer, and it reads fine.ReFS volume appears as RAW after rebuild of server
I had a Windows 2022 server that had a drive formatted as ReFS. The hardware failed and I had to get a new system. The Windows installation also got corrupted when the hard failed. I have the new hardware and I have installed Server 2022 again but the drive is coming up as Raw and ReFS failed to mount the volume. Version 3.14 doesn't match expected value 3.7 is appearing in the ReFS/Operational event logs. I connected the drive to a Windows 11 Pro pc and are able to view the drive. Why has this happened? Is there a way to upgrade the version of RsFS to 3.7? Is there something I have missed when building the new server?
