When taking an S2D server offline for patching or other reasons, it is not only taking away the compute and memory for that server but also a portion of the storage pool. Care must be taken to keep your data safe and ensure quick resumption of production-level readiness to your cluster.
9. A storage job will initiate in the background to repair and resync the data. To check on the status, run (as Admin)Get-StorageJob If it returns to a command prompt that means there are no jobs running.Do not reboot the next node until all of the jobs have been completed.
10. RunGet-VirtualDiskto verify the virtual disks are healthy after storage jobs complete.Wait until steps 9 and 10 have been completed before live migrating VMs back to this node as storage jobs will consume system resources potentially affecting the response time of your applications.
11. RunResume-ClusterNode -Failback Immediateto put the cluster node back into production to handle VM workloads.
Alternative:
The steps to reboot each servers can take some time especially with post storage resync and repair. If you have the ability to shutdown the entire cluster this link will walk through the steps to make the entire process faster.
Right click on the cluster or select ‘More Action’ on the Actions panel on the right
Select ‘Configure Cluster Quorum Setting’
This will open the Quorum Wizard and select ‘Next’ to continue
Select the second options. ‘Select the quorum witness’
Next select the last options to disable the quorum witness. ‘Do not configure a quorum witness’
Once the witness is removed. Check the Failover Cluster Manager to make sure it is removed in the 'Cluster Core Resources’
How to Enable Cluster Quorum:
Open Failover Cluster Manager
Select the cluster
Right click on the cluster or select ‘More Action’ on the Actions panel on the right
Select ‘Configure Cluster Quorum Setting’
This will open the Quorum Wizard and select ‘Next’ to continue.
Select the second options. ‘Select the quorum witness’
Here you can select 3 different Quorum Witness:
Disk Witness: will create a witness on a disk. This is not an option for Storage Space Direct (S2D) because it does not work. The option is there for Storage Space. It not recommended by DataON.
File Share Witness: Will create a small file which will act as the witness. Recommend having the witness on another cluster, server, or workstation that is not on the cluster itself.
Cloud Witness: will create a witness on the cloud. This requires a Azure account and subscription. This also require having constant internet connection for the witness to be active.
Once you select the Witness, select the path where the witness will lie.
Confirm the witness and select ‘Next
Once it is configure, you will reach the summary page and select ‘Finish’ to exit.
There are three high-level steps for migration of VMs from an existing cluster to a new cluster.
Setup new servers and storage and configure iSCSI access to new storage.
Setup Hyper-V and failover clustering.
Setup the CSV storage for the new cluster.
There are two methods by which you can migrate VMs from an existing cluster to a new cluster:
Option 1 You could transfer roles to the new cluster, but this does not move any of the actual data for the VMs. If you are using iSCSI with different LUNs and mount points, the process is more involved for migrating the roles and VMs. The easier process is to simply remove each of the Hyper-V VM roles from the failover cluster manager and use the native Hyper-V Manager to “move” the actual VM’s to the new cluster. Both processes can be done while the VMs are running.
Option 2 Use the built-in Microsoft “Shared Nothing Live Migration” to migrate VMs to new cluster. For the live migration to work between servers you must initiate the move from the source server. Otherwise you need to employ Kerberos authentication for the Hyper-V settings > Live Migration > Advanced settings and the Delegation > Trust properties of the computer object. It is highly recommended to start this process on non-production VMs at first to ensure the process works smoothly!!
Here are the simple step-by-step instructions how to perform this migration.
Step 1: Remove Role
Open Failover Cluster Manager and remove the virtual machine role for the VM you want to move. This does not remove the VM, it simply removes it from the cluster manager and thus is no longer highly available.
Step 2: Hyper-V Manager Move
Open Hyper-V Manager on the server where the VM resides. Right-click the VM and select Move.
Step 3: Select Type of Move
Select the type of move you want to perform. The top option allows you to move the entire VM (config, snapshots, VHDs, etc.).
Step 4: Destination Server Name
Specify the name of your destination server. This is not the cluster name but one of the nodes in the cluster.
Step 5: What to Move
Now select what you want to move. Again, the top option moves all the VM files necessary to run the VM on a different server.
Step 6: Choose folder and move
Browse and select the CSV volume (already created as part of the cluster setup process). We recommend creating a folder with the name of the server inside the CSV for easier identification. Click Next to perform the move.
Step 7: Network Check
When the move initially begins, it pre-checks a variety of things to make sure the move will be successful. One of those items is the virtual switch the VM is connected to. If your virtual switches have the same name between your clusters, then you will not receive this prompt. In this example, there was a prompt for the virtual switch for the VM to connect with due to the name change as shown here. If you have snapshots of the VM, these will also move but you will be prompted for the switch to connect with, if the names are different.
Step 8: Finishing up
The tool will move and preserve the snapshots which you cannot do with the export option. This is one of the main reasons the Move feature is recommended.
Below is a step-by-step guide on how to add a third node to an existing 2-node Storage Spaces Direct (S2D) cluster with the production workload still running.
1.) Ensure that the cluster is configured with a witness.
2.) Pause/Drain a node in the cluster.
3.) Place the paused node's drives into a storage maintenance mode.
4.) Physically add the 3rd node into the 2-node cluster configuration by cabling the three servers like the image below:
DataON2UPlatforms:
DataON1UPlatform:
5.) Make sure the node that is being added to the cluster has the same firmware and drivers installed as the two servers in the existing 2-node cluster. Also install the necessary Windows features and configure the network correctly. Before adding the third node to the cluster, run a cluster validation.
8.) By adding a third node to the S2D cluster, 3-way-mirror resiliency is unlocked; Run the following command to configure this setting on the existing storage pool.
The value of business data grows to the extent that companies simply cannot ignore the importance of a safe data storage. Modern technologies offer a variety of methods how to warrant a highly-available and fault-tolerant storage. One of the techniques includes synchronous mirroring – an approach when a source storage has an exact replica (one or more). At the same time, the data is considered written only when the primary storage receives a signal that all secondary copies have been created. This document suggests taking a look at two-way and three-way synchronous mirroring to better understand the benefits each of them has behind.
Cost-efficiency
2-way synchronous mirroring
This configuration requires storage redundancy on the nodes. The use of RAID10* is recommended. 2-node HA ensures the synchronous mirroring of data between two storage nodes. Taking into account that each storage node has only 50% of usable capacity with RAID10, synchronous mirroring makes the further dividing of those 50% by half resulting in the underutilization of storage capacity – only 25% is used.
* RAID10 use is recommended for a HDD setup. In case of RAID5 use in a HDD setup, there arises the risk of disk failure while rebuilding RAID5. RAID6 in a HDD setup gives low write performance. At the same time, RAID5 and RAID6 configurations can be used for SSD setups due to a high tolerance to physical failures and faster performance of the latter.
With 2-way synchronous mirroring, usable capacity is 25% – ¼ of storage space
3-way synchronous mirroring
Non-redundant RAID0 configuration provides the highest level of performance, therefore, RAID0 can be used for performance. Synchronous mirroring between 3 storage nodes with RAID0 configured on each, results in 33% usable capacity and thus provides a higher level of storage utilization compared to 2-way synchronous mirroring. While it looks like this configuration does not require storage redundancy on nodes (since 3-way synchronous mirroring already ensures the required level of data protection), you should evaluate the potential risks of disks failing and potential data loss probability (if disks failed on all 3 nodes). Assuming the above, please make sure that the data is protected by backup applications according to the 3-2-1 backup rule.
With 3-way synchronous mirroring, usable capacity is 33% – 1/3 of storage space
As a result, 3-way synchronous mirroring increases the storage utilization rate. The cost-efficiency of this configuration differs depending on the medium type – spindle or flash. The difference is shown on the charts below.
Increased reliability
2-way synchronous mirroring
2-way synchronous mirroring provides 99.99% uptime. The outage of one storage node results in a single point of failure and immediately brings the system to a degraded performance mode. Cache is flushed and turned from write-back to write-through mode on the running node. A number of MPIO paths is reduced twofold because one node is down. Consequently, the storage performance falls.
With 2-way synchronous mirroring, there is a risk of downtime
3-way synchronous mirroring
3-way synchronous mirroring provides 99.9999% uptime. No single point of failure occurs when one node of a 3-node storage cluster goes down. In such a situation, storage performance falls by up to 33% because the system loses 1/3 of the MPIO paths. Performance-critical applications usually can continue running in an ordinary way. The 3-node HA configuration tolerates a double fault and retains the availability of service.
With 3-way synchronous mirroring, constant system uptime is ensured
Higher performance
Higher storage performance is influenced by a number of factors, which include I/O policy, RAID level and cache policy. The effect of these factors is given below:
MPIO paths
2-way synchronous mirroring
With Round Robin/List Queue Depth policy used, I/Os are processed up to two times faster comparing to a single-node configuration.
3-way synchronous mirroring
Owing to the Round Robin/List Queue Depth policy, the I/Os throughput rises by a factor of 3 compared to single-node storage.
As a result, performance is increased by up to 50% compared to a 2-node configuration.
RAID10 vs RAID0
2-way synchronous mirroring
This configuration strongly requires extra redundancy for data protection on the storage nodes themselves. This redundancy can be provided through the use of RAID. RAID10* is recommended for a HDD setup as it ensures mirroring between the disk stripes and makes fast reads and writes. However, storage utilization is considerably low because the same data is mirrored and stored on two stripes of RAID.
* Use of RAID5, RAID6 for a HDD setup is possible but not recommended because of the high probability of a disk failure while rebuilding RAID5, and the low write performance of RAID6. At the same time, RAID5 and RAID6 configurations can be used for SSD setups due to a high tolerance to physical failures and faster performance of the latter.
3-way synchronous mirroring
RAID0 can be used for performance. Both reads and writes are faster here as the system reads the data from all disks simultaneously. With RAID0 you should evaluate the potential risks of disks failing and potential data loss probability (if disks failed on all 3 nodes).
Cache policy
2-way synchronous mirroring
If one node fails, the cache is flushed and turned from write-back to write-through mode and the system immediately switches to a degraded performance mode on reads.
With 2-way synchronous mirroring,cacheis flushed and turned to write-through mode causing critical performance degradation
3-way synchronous mirroring
If one node goes down, the system downgrades from a 3 to 2-node cluster and continuous operation with minimal performance degradation (about 33%) due to the absence of one node and because a number of MPIO paths is reduced.
With 3-way synchronous mirroring, cache policy remains write-back that results in minor performance degradation
Important note:Even the highest possible level of redundancy and reliability does not ensure 100% protection against data loss, e.g. due to malicious actions or disaster. So, nothing compares to a good old backup that substantially increases the chances your data is in place.
Conclusion
With synchronous mirroring admins can decide on either two-way mirroring – to ensure basic data protection and high availability, or three-way mirroring – to increase overall system reliability and to also “play games with” cost-efficiency and performance.
In this article, I’ll show you how to use the SCCM feature update option to perform a Windows 10 22H2 upgrade. We will use Windows Servicing in SCCM to upgrade Windows 10 devices to version 22H2 via the enablement package.
Windows 10, version 22H2, also known as theWindows 10 2022 Update, is available for eligible devices runningWindows 10, versions 20H2and newer. Microsoft released Windows 10, version 22H2 (KB5015684) on 18th October 2022, and it is an enablement package.
For home users running Windows 10 version 20H2 and later, the recommended way to get the Windows 10 22H2 is via Windows Update. Go toStart>Settings>Windows Updateand runCheck for Updates. Select theFeature update to Windows 10, version 22H2and install it.
When you want to upgrade multiple Windows 10 devices to version 22H2, Configuration Manager is the best tool. It simplifies the way youdeploy and manage updatesand saves a lot of time. With Configuration Manager, you can select the “Feature Update to Windows 10 Version 22H2 via Enablement Package” and deploy it to a set of devices.
Ways to upgrade to Windows 10 22H2
There are multiple ways that you can use to upgrade to Windows 10 version 22H2.
Get the Windows 10 22H2 update via Windows Update.
Use Servicing Plans to upgrade eligible Windows 10 devices to version 22H2.
Upgrade Windows 10 21H2 to Windows 10 22H2 using ConfigMgr Windows Servicing feature.
Deploy the Windows 10 22H2 update using the SCCM task sequence.
Using the Intune to upgrade to Windows 10 22H2 upgrade for WUfB managed devices.
We will use the Configuration Manager feature update option to deploy the Windows 10 22H2 enablement package out of all the above methods. This is the easiest and quickest way I can think of to update Windows 10 to version 22H2.
Can I use SCCM Servicing Plans to Upgrade to Windows 10 version 22H2?
Yes, you can use the Servicing Plans in SCCM to upgrade the computers running Windows 10 to version 22H2. WithConfiguration manager servicing plansyou can ensure that all the Windows 10 systems are kept up-to-date when new builds are released. Servicing plans are ADR that can help you to upgrade Windows 10 to version 22H2. Take a look at detailed guide onWindows 10 Servicing Plans in SCCM.
If you are unsure whether to upgrade to Windows 10 22H2 using a Servicing Plan or a feature update deployment, I would advise choosing the latter. There are only a few steps involved in deploying a Windows 10 22H2 feature update, making it much simpler than a servicing plan. You get to make the final decision.
Windows 10 22H2 is an enablement package and this is good news for admins. The enablement package is a great option for installing a scoped feature update like Windows 10, version 22H2. You can upgrade from version 2004, 20H2, 21H1, or 21H2 to version 22H2 with a single restart, reducing update downtime. Since Windows 10 22H2 is an enablement package, the devices currently on Windows 10, version 20H2 or newer will have a fast installation experience because the update will install like a monthly update.
Prerequisites
With Configuration Manager, you need few things to be configured before you deploy the feature updates to computers. If you have deployed the feature updates before, it means most of the prerequisites are already taken care of. If your SCCM setup is new, you may have to configure them once before deploying the upgrades.
Listed below are all the prerequisites required for Windows 10 22H2 upgrade using SCCM.
Let’s look at steps for downloading Windows 10 22H2 enablement package using SCCM. First of all ensure you have synchronized the updates in Configuration Manager. You can either download the feature first and deploy or directly deploy the feature update. I prefer to download it first, let the content get distributed to distribution points and then deploy it.
Go toSoftware Library>Overview>Windows 10 Servicing>All Windows 10 Updates. Look for the update “Feature Update to Windows 10 Version 22H2 x64-based systems 2022-10 via Enablement Package“. You can also search the updates with article ID 5015684.
Download Windows 10 22H2 Enablement Package
If you have got both x64-based systems and x86-based systems, you must download Feature Update to Windows 10 Version 22H2 x64-based and x86-based. In my lab, all my Windows 10 VMs are running Windows 10 64-bit OS, and therefore I am going to download onlyFeature Update to Windows 10 Version 22H2 x64-based systems 2022-10 via Enablement Package.
Create Deployment Package
On theDeployment packagewindow, specify the deployment package for Windows 10 22H2 upgrade files. This deployment package that you create will contain the software update files that will be deployed to the clients.
SelectCreate a new deployment packageand specify the package name as “Windows 10 22H2 Deployment Package.” Add a brief description and specify the package source – a shared folder where you want to download the updates.Enabling the binary differential replicationis optional. ClickNext.

How to Change Configuration Manager(SCCM) Console Language
This post explains how to change or modify the default Configuration Manager (SCCM) console language. It also covers on how to change console language back to English.
By default the SCCM console picks the system language. However sometimes the technical support members will need the console in English or probably some other language.
During site server installation, the Configuration Manager console installation files and supported language packs are copied to the \Tools\ConsoleSetup. This is a sub-folder within the Configuration Manager installation path on the site server.
When you start the Configuration Manager console installation from this folder on the site server, it copies the Configuration Manager console and supported language pack files to the computer.
When a language pack is available for the current language setting on the computer, the Configuration Manager console opens in that language.
However if the associated language pack isn’t available for the Configuration Manager console, the console opens inEnglish (United States).
About Configuration Manager Console
The Configuration Manager console is a tool that allows managing the Configuration Manager environment. By default the SCCM console is always installed on every site server.
It allows you to perform functions such as deploy applications, configure the settings, device management, and create packages and collections.
The Configuration Manager Console is a single management console for your PCs, Macs and Unix/Linux servers, as well as for mobile devices running Android, Windows or iOS.
For more information on ConfigMgr console deployment, refer below posts.
In order to modify the language of Configuration Manager console
You must to be administrator of the computer on which you perform the below changes.
Have access to the installation files. (Download package language folder)
Change SCCM Console language to English
The below steps will now help you to change the SCCM console language from French language to English.
In this example, by default SCCM Console is displayed in the system language which is French.
The English language file is by installed by default when you install Windows 10.
First of all close the Configuration Manager console, and go to your console installation directory. %program files (x86)%\ Microsoft Configuration Manager\AdminConsole\bin.
Since our current console language is French, rename the fr folder to fr.old.
Now launch Configuration Manager console. Notice that the console language is English. We changed the SCCM console language from French to English with simple file rename.
Modify SCCM Console language from English to other language
We will now look at the steps to modify our SCCM console language from English to some other language.
To choose another language other than English, you require the files for your language. You then change the system language.
Go to download folder. Select Server folder and your language. (in my example ESN for Spain).
Run the file ALPxxxx.msp. Wait while the installation is done.
Go to Configuration Manager console installation directory and open the bin folder. We see a new folder es in the bin directory.
Now change your Windows 10 OS system language.
Right click Start and clickSettings.
Click onTime & Languageand then clickLanguage.
Under the Preferred languages section, clickAdd a preferred language.
Search for the language you want on Windows 10. Select the language package from the list.
Ensure you set the new language as display language. ClickInstall.
Now launch Configuration Manager console. Notice that the new console language is now Spanish.
