Clustering FileServer Data Deduplication on Windows 2016 Step by Step #sofs #winserv #ReFS #WindowsServer2016 #Dedupe   4 comments

Building a File server in Server 2016 isn’t that different tan in Server 2012R2 except there are different options, ReFS, DeDupe and a lot more options. As we start with the basic file server clustered and using ReFS and Data Duplication. This is a common scenario and can also be used in Azure.

Data Deduplication can effectively minimize the costs of a server application’s data consumption by reducing the amount of disk space consumed by redundant data. Before enabling deduplication, it is important that you understand the characteristics of your workload to ensure that you get the maximum performance out of your storage.

In this demo I have a two node cluster a quick create of the cluster. This is a demo for file services.

Create Sample Cluster :

#installing the File server and cluster features

Get-WindowsFeature Failover-Clustering
install-WindowsFeature "Failover-Clustering","RSAT-Clustering" -IncludeAllSubFeature
Restart-Computer –Computername Astack16n014,Astack16n015 –force
 
#Create cluster validation report
Test-Cluster -Node Astack16n014,Astack16n015
 
#Create cluster
New-Cluster -Name Astack16R5 -Node Astack16n014,Astack16n015 -NoStorage -StaticAddress "10.255.255.41"

 

image

Now that the Cluster is in place we can start with the basic of the file cluster, the disks need to be sharable so no local disks.

If you want to build a file server with local disk only then we should use storage spaces direct, I’ll use this in the next blog post.

We add a shared disk to the cluster. Enable the disk and format the disk.

imageimage

I format the disk with ReFS as this is the next file structure and has more options than NTFS.

The next iteration of ReFS provides support for large-scale storage deployments with diverse workloads, delivering reliability, resiliency, and scalability for your data. ReFS introduces the following improvements:
  • ReFS implements new storage tiers functionality, helping deliver faster performance and increased storage capacity. This new functionality enables:
    • Multiple resiliency types on the same virtual disk (using mirroring in the performance tier and parity in the capacity tier, for example).
    • Increased responsiveness to drifting working sets.
    • Support for SMR (Shingled Magnetic Recording) media.
  • The introduction of block cloning substantially improves the performance of VM operations, such as .vhdx checkpoint merge operations.
  • The new ReFS scan tool enables the recovery of leaked storage and helps salvage data from critical corruptions.

image

The disk is formatted and added to the cluster,showing as Available Storage.

image

Our next step would be Adding the File server role to the cluster.

image

image

The question here is is this a normal file server or do you want to build a sofs cluster. Currently SOFS is only supported for RDS UPD,Hyper-v,SQL. Comparing both SOFS and a file server.

SOFS = Active – Active File share

Fileserver = Active – Passive File share

We are sing the file server for general usage.

image 

Give your file server a name. Remember this is the netbios name and needs to be in the DNS!

imageimage

Default is a DHCP IP but I assume you will set this to fixed or make this static in the DHCP & DNS

image

Now that the file server and the disk is added to the cluster we can start the file Server and add some shares to this

add the file share.

image

image

When adding the file share we see this error “ client access point is not ready to be used for share creation”

This is a brand new File Server and already broken ? well no reading this error message it said we can’t access the netbios name

image

We we do properties on the file server you can see there is a DNS failure. It can’t add the server to the DNS or the registration is not correct.

Just make sure the name is in the DNS and a nslookup works.

image

When adding the file share you get a couple off options, and lets pick the SMB share Quick option

image

Get the file share location, this would be on the shared disk in the cluster. if there are no folders make the folder first.

imageimage

I Give the folder a name and put this to the right disk.

image

Here you can pick a couple of options and some are already tagged. I this case I only use access-based enumeration.

imageimage

The file server is ready. clients can connect. Access ACL must be set but this depends on the environment.

Our next step is enable Data Deduplication on this share. It is a new option in Server 2016. Want to know what is new in Windows Server 2016 https://docs.microsoft.com/en-us/windows-server/storage/whats-new-in-storage

Data Deduplication

Install Data Deduplication every node in the cluster must have the Data Deduplication server role installed.

To install Data Deduplication, run the following PowerShell command as an administrator:

Install-WindowsFeature -Name FS-Data-Deduplication

image

  • Recommended workloads that have been proven to have both datasets that benefit highly from deduplication and have resource consumption patterns that are compatible with Data Deduplication’s post-processing model. We recommend that you always enable Data Deduplication on these workloads:
    • General purpose file servers (GPFS) serving shares such as team shares, user home folders, work folders, and software development shares.
    • Virtualized desktop infrastructure (VDI) servers.
    • Virtualized backup applications, such as Microsoft Data Protection Manager (DPM).
  • Workloads that might benefit from deduplication, but aren’t always good candidates for deduplication. For example, the following workloads could work well with deduplication, but you should evaluate the benefits of deduplication first:
    • General purpose Hyper-V hosts
    • SQL servers
    • Line-of-business (LOB) servers
Before enabling the Data Deduplication we can first check and see if there any savings are by doing this.

Run this in a Command or powershell command where e:\data is or data location that we are using for the dedupe

C:\Windows\System32\DDPEval.exe e:\data

image

Even with a few files there is a saving.

get-volume -DriveLetter e

image

To enable the dedupe go to server manager , volumes and select the disk that need to be enabled.

image

Selecting the volume that needs Dedupe other volumes won’t be affected. It’s important to note that you can’t run data deduplication on boot or system volumes

imageimageimage

The setting of the # days can be changed in to something what suite you.

image

When enabling Deduplication, you need to set a schedule, and you can see above that you can set two different time periods, the weekdays and weekends and you can also enable background optimization to run during quieter periods, and for the rest it is all powershell there is no gui on this.

Get-Command -Module Deduplication will list all the powershell commands

image

Measure-DedupFileMetadata -Path e:\data

image

I places some of the same ISO files on the volume and as you can see there is a storage saving.

get get the data run an update on the dedupe status.

Update-DedupStatus -Volume e:

image

image

It is all easy to use and to maintain. If you have any cluster questions just go to https://social.technet.microsoft.com/Forums/windowsserver/en-US/home?forum=winserverClustering and I’m happy to help you there and also other community or microsoft guys are there.

Windows Server 2016 Setting port priority Adjusting the Network #Protocol Bindings multiple networks #winserv   Leave a comment

When building complex network configurations with Server 2016 you will need to adjust sometimes configuration settings that are not that easily to change in the GUI.

Suppose I have a big S2D cluster Or a NLB farm

In this configuration I have a Cluster that is using Storage spaces direct #S2D but On the SMB nic I don’t want to connect with RDP 

Or in the NLB farm I want to use a NLB nic that is used for RDP.

with the  Get-NetIPInterface we get a listing of the networks

image

Get-NetAdapter shows us the name and nic name

image

Our net step is list the current configuration and his settings for the Ports, in this case RDP

# list current settings
gwmi Win32_TSNetworkAdapterSetting -filter "TerminalName=’RDP-Tcp’" -namespace "root/cimv2/TerminalServices" | Select NetworkAdapterLanaID,NetworkAdapterName

image

ID 0 which is "All network adapters configured with this protocol"

More info about Win32_TSNetworkAdapterSetting can be found here :

https://msdn.microsoft.com/en-us/library/aa383811(v=vs.85).aspx

when we combine this in a variable to get some more info

#show netadapter bindings for RDS

$MVPRDP = gwmi Win32_TSNetworkAdapterSetting -filter "TerminalName=’RDP-Tcp’" -namespace "root/cimv2/TerminalServices"

$MVPRDP | select -expand DeviceIDList

image

As this is the network name it is not that handy use this with the get-netadapter
$MVPRDP | select -expand NetworkAdapterList

image

Now we know what to set on which adapter

# ID 0 which is "All network adapters configured with this protocol". 0,1,2,3

SO ID 0 is all and start counting with 1 as I want RDP only on my MGT lan I set this on Adapter 2

$MVPRDP.SetNetworkAdapterLanaID(2)

image

gwmi Win32_TSNetworkAdapterSetting -filter "TerminalName=’RDP-Tcp’" -namespace "root/cimv2/TerminalServices" | Select NetworkAdapterLanaID,NetworkAdapterName

image

now a little reboot and just to make sure there are no old connections and your done.

 
Or use a register key to set this option but what fun is that.

set HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\Winstations\RDP-tcp\LanAdapter

Building a Windows Server 2016 Domain Controller #winserv #Hybrid #cloud #Azure #powershell   Leave a comment

Building a Domain Controller is not that Difficult but what about building this with Powershell and use the 2016 Bits.

Well lets take a peek at the Technet site https://technet.microsoft.com/en-us/library/hh974720(v=wps.630).aspx nothing about 2016.

-DomainMode<DomainMode>

Specifies the domain functional level of the first domain in the creation of a new forest. Supported values for this parameter can be either a valid integer or a corresponding enumerated string value. For example, to set the domain mode level to Windows Server 2008 R2, you can specify either a value of 4 or Win2008R2. So

The following are the supported values:
     — Windows Server 2003: 2 or Win2003
     — Windows Server 2008: 3 or Win2008
     — Windows Server 2008 R2: 4 or Win2008R2
     — Windows Server 2012: 5 or Win2012
     — Windows Server 2012 R2: 6 or Win2012R2

Well it makes sense that the Next line would be  — Windows Server 2016: 7 or Win2016

Le me try that in Azure.

First I deploy the windows feature Active Directory

Install-windowsfeature AD-domain-services -IncludeAllSubFeature –IncludeManagementTools

The next step would be Deploy Active Directory and at the end you will be asked for a recovery password.

Install-ADDSForest `
-CreateDnsDelegation:$false `
-DatabasePath "C:\Windows\NTDS" `
-DomainMode "7" `
-DomainName "mvpdemo01.local" `
-DomainNetbiosName "mvpdemo01" `
-ForestMode "7" `
-InstallDns:$true `
-LogPath "C:\Windows\NTDS" `
-NoRebootOnCompletion:$false `
-SysvolPath "C:\Windows\SYSVOL" `
-Force:$true

I did a Force:$true So a reboot is following so no time for a screenshot and wait for things.!

But After the reboot you will have a DC

image

and Joining a DC Member : Add-WindowsFeature AD-Domain-Services

Install-windowsfeature AD-domain-services -IncludeAllSubFeature –IncludeManagementTools

Add-WindowsFeature AD-Domain-Services `
-CreateDnsDelegation:$false `
-DatabasePath "C:\Windows\NTDS" `
-DomainMode "7" `
-DomainName "mvpdemo01.local" `
-DomainNetbiosName "mvpdemo01" `
-ForestMode "7" `
-InstallDns:$true `
-LogPath "C:\Windows\NTDS" `
-NoGlobalCatalog:$false `
-NoRebootOnCompletion:$false `
-SysvolPath "C:\Windows\SYSVOL" `
-Force:$true

 

Joining a Member server

I created a noob account that is only allowed to join a server to the domain

 

Write-Host "Hostname / Node Names" -ForegroundColor yellow
$domain = "mvpdemo01.local"
$password = "Password01" | ConvertTo-SecureString -asPlainText -Force
$username = "$domain\noob"
$credential = New-Object System.Management.Automation.PSCredential($username,$password)
Add-Computer -DomainName $domain -Credential $credential
restart-computer -force

image

See how easy things can be.

Upgrading Hyper-v Server 2012R2 to Server 2016 now what ? #hyperv #winserv #RollingOS   2 comments

So you have done a rolling Upgrade – see Cluster operating system rolling upgrade To all your Hyper-V servers but other than a different logon screen you see no difference. Where are all the options ? Well you will need to do some extra steps. To get the full Hyper-v 2016 Server.

Illustration showing the three stages of a cluster OS rolling upgrade: all nodes Windows Server 2012 R2, mixed-OS mode, and all nodes Windows Server 2016

All the VM options are the Same Did I miss something or is there another configuration option as I created a new VM it has all the new options.

Do I need to recreate all the VM’s ?, where is the hidden option to change this ? a while a go I created a blog post on

Windows Server 2016 with Hyper-v Upgrading Configurations —Windows Server 2016 with Hyper-v Integrations tools & configuration versions

Well this was still on a TP version so the numbers has changed but not the methods. But there is no gui option in the Hyper-v Server that can flip the bit to the new Configuration version. It is done only by Powershell. with that Let us see how this is changed.

image image

Old VM settings vs the New VM Settings.

Do I need to recreate all the VM ? NO are you nuts. this would be odd. Lets dive in a little bit deeper.

In the Hyper-v Manager you can see the configuration and generation version in the 2012R2 this is version 5.0

image

In windows server 2016 the Hyper-v configuration version is now 8.0

image

With the get-VM we can see the Configuration version of the VM

Get-VM | ft Name, IntegrationServicesVersion,version 

image

as you can see I have a version 5.0 and a 8.0 just as in the screen shots above.

Now changing this is a ONEWAY thing and If you have an OLD none 2016 version in your Cluster then the VM would fail if it runs on this node. Version 8.0 runs only on Hyper-V 2016 !

To list all the Supported Configurations On this Server we can do a “ Get-VMHostSupportedVersion “

 

image

So there are Currently seven different versions. With all the options why should I care setting this.

Well there are a couple of reasons why you should set this option. Make the latest Hyper-V features available on your virtual machines by upgrading the configuration version. Don’t do this until:

  • You upgrade your Hyper-V hosts to the latest version of Windows or Windows Server.
  • You upgrade the cluster functional level.
  • You’re sure that you won’t need to move the virtual machine back to a Hyper-V host that runs a previous version of Windows or Windows Server.

And you you replicate from a Hyper-v 2016 Server to a Hyper-v 2012 Server for DR then make sure you don’t run in a higher version than 5.0

When you move or import a virtual machine to a computer that runs Hyper-V on Windows Server 2016 or Windows 10, the virtual machine’s configuration isn’t automatically updated. This means that you can move the virtual machine back to a Hyper-V host that runs a previous version of Windows or Windows Server. But, this also means that you can’t use some of the new virtual machine features until you manually update the configuration version. You can’t downgrade the virtual machine configuration version after you’ve upgraded it.

The virtual machine configuration version represents the compatibility of the virtual machine’s configuration, saved state, and snapshot files with the version of Hyper-V. When you update the configuration version, you change the file structure that is used to store the virtual machines configuration and the checkpoint files. You also update the configuration version to the latest version supported by that Hyper-V host. Upgraded virtual machines use a new configuration file format, which is designed to increase the efficiency of reading and writing virtual machine configuration data. The upgrade also reduces the potential for data corruption in the event of a storage failure

Building a VM based on Windows 2012R2 configuration You should use this PowerShell command as you could see the 8.0 Configuration is default.

New-VM -Name “DemoVM17” -Version 5.0

When listing the VM Configurations you can see the difference. and easily see the 5.0 Version VM’s  config.XML

Virtual machine configuration information that is stored in binary file format. File name extension: .vmcx

image

But what if I want to upgrade the VM’s ? yes you can but only to the default level and PowerShell Only

Update-VMVersion “VM Name”

image

as you can see the DemoVm06 is already at the max level but when updating the DemoVM01 which has Version 5.0 it will be upgraded to Version 8.0 and the Config file will be transferred this can’t be undone!

Virtual machine configuration information that is stored in binary file format. File name extension: .vmcx

you can automate this and do all upgrades in onetime or have a pick list to do this. But the VM needs to be OFF no running VM can be upgraded.

TO upgrade all VM’s   Update-VMVersion * -force

Or pick the VM by yourself with a before and after version.

#Select a VM to upgrade
$vm2016= (Get-VM | select Name, Status, version | Out-GridView -Title "Select VM for update the configuration version" -PassThru).Name
#list VM configuration Version
Get-VM $vm2016 | ft Name, IntegrationServicesVersion,version 
#Convert the Config TO the default Configuration
Update-VMVersion $vm2016 -Force -Verbose
#list VM configuration Version
Get-VM $vm2016 | ft Name, IntegrationServicesVersion,version

Windows Server 2016 NLB Network Load Balancing non-SDN or Software Load Balancing (SLB) for SDN #NLB #SLB #SDN   Leave a comment

Windows Server 2016 Network Load Balancing. You can use Network Load Balancing to manage two or more servers as a single virtual cluster. Network Load Balancing enhances the availability and scalability of Internet server applications such as those used on web, FTP, firewall, proxy, virtual private network (VPN), and other mission-critical servers.

New in Windows Server 2016 is it includes a new Azure-inspired Software Load Balancer (SLB) as a component of the Software Defined Networking (SDN) infrastructure. Use SLB instead of NLB if you are using SDN, are using non-Windows workloads, need outbound network address translation (NAT), or need Layer 3 (L3) or non-TCP based load balancing. You can continue to use NLB with Windows Server 2016 for non-SDN deployments.

So We got now two Load Balancing features :

Network Load Balancing (NLB) for non-SDN

Software Load Balancing (SLB) for SDN

Software Defined Networking (SDN) provides a method to centrally configure and manage physical and virtual network devices such as routers, switches, and gateways in your datacenter. Virtual network elements such as Hyper-V Virtual Switch, Hyper-V Network Virtualization, and Windows Server Gateway are designed to be integral elements of your software defined networking infrastructure. While you can still use your existing physical switches, routers, and other hardware devices, you can achieve deeper integration between the virtual network and the physical network if these devices are designed for compatibility with software defined networking.

Network Load Balancing (NLB) for non-SDN

For this demo I created a NLB script that can be found here Create a Windows Server 2016 NLB Network Load Balancing farm https://gallery.technet.microsoft.com/Create-a-Windows-Server-05a13f14

I use a couple of Windows Server 2016 server for the Load Balancing each node has two network adapters and runs IIS with a default website

Network Load Balancing and other software components

 

Network Load Balancing is not nic teaming as nic teaming is on the same host and Network Load Balancing is combining all nodes to one VIP Virtual IP address.

First we install the NLB feature on each node.

Install-WindowsFeature NLB –IncludeManagementTools

To view a complete list of NLB CMDlets type the following CMDlet, Get-command -module NetworkLoadBalancingClusters

image

To Create a New NLB Cluster you can do this in the GUI or in Powershell

image

First I rename the Network Adapter to get a better overview

#Rename NIC
Rename-NetAdapter -Name "Ethernet" -NewName "NLB"

#Create NLB
New-NLBCluster –Interface “NLB” -OperationMode Unicast -ClusterPrimaryIP  -ClusterName WS2016NLB –verbose

Showing the NLB cluster info

Get-NLBClusterNode | Format-List *

image

then I removed all the default rules why would you NLB all the ports ?

#Removing default port rule for the NLB Cluster
Write-Host "Removing default port rule…" -ForegroundColor yellow
Get-NlbClusterPortRule -HostName . | Remove-NlbClusterPortRule -Force

#Adding port rules 80
Write-Host "Added port rule for http (tcp 80)" -ForegroundColor yellow
Add-NlbClusterPortRule -Protocol Tcp -Mode Multiple -Affinity Single -StartPort 80 -EndPort 80 -InterfaceName $InterfaceName -IP $ClusterPrimaryIP| Out-Null
#Adding port rules 443
Write-Host "Added port rule for https (tcp 443)" -ForegroundColor yellow
Add-NlbClusterPortRule -Protocol Tcp -Mode Multiple -Affinity Single -StartPort 443 -EndPort 443 -InterfaceName $InterfaceName -IP $ClusterPrimaryIP| Out-Null

Now that Port 80 and 443 are in the NLB we can add some nodes

As I added the -Affinity Single option keep in mind that your application support this option. Running websites parts from different servers is sometimes a pain for the developer.

The Affinity parameter is applicable only for the Multiple hosts filtering mode.

  • The None option specifies that multiple connections from the same client IP address can be handled by different cluster hosts (there is no client affinity). To allow Network Load Balancing to properly handle IP fragments, you should avoid using None when selecting UDP or Both for your protocol setting.
  • The Single option specifies that NLB should direct multiple requests from the same client IP address to the same cluster host. This is the default setting for affinity. You can optionally modify the NLB client affinity to direct all client requests from a TCP/IP Class C address range (instead of a single IP address) to a single cluster host by enabling the Network option instead of the Single option. This feature ensures that clients that use multiple proxy servers to access the cluster can have their TCP connections directed to the same cluster host.
  • The Network option specifies that NLB direct multiple requests from the same TCP/IP Class C address range to the same cluster host. Enabling Network affinity instead of Single affinity ensures that clients that use multiple proxy servers to access the cluster have their TCP connections directed to the same cluster host.
    The use of multiple proxy servers at the client’s site causes requests from a single client to appear to originate from different computers. Assuming that all of the client’s proxy servers are located within the same address range, Network affinity ensures that client sessions are properly handled. If you do not need this capability, use Single affinity to maximize scaled performance.

 

adding a second node is easy in Powershell or do this in the GUI add node and follow the steps.

$InterfaceName = “NLB”
$Node2Fqdn=”MVPNLB502.mvp.local”

Get-NlbCluster -HostName $env:COMPUTERNAME | Add-NlbClusterNode -NewNodeName $Node2Fqdn -NewNodeInterface $InterfaceName –Verbose

image

and as you can see if you don’t rename all the nic adapters it looks a bit messy. If you ever need to troubleshoot then it is easy to get NLB traffic and or other network traffic.

Now that the NLB cluster is ready we can use it for say a webserver. make sure the DNS Record is created in the DNS and If you are using multiple Cluster Virtual IP’s make sure they are also in the DNS. I always use an IP for the cluster and for the websites I use separate IP’s and all sites running on different IP’s / NLB VIP If I need to change some thing on the webserver it has no impact on all the other servers. I also Added a few more NLB nodes. that has already a configured website.

 

Now to get this to work with IIS

image

That is right page not found. Check the DNS see if the record is created. and make sure the website IIS is running on this IP

Go to the IIS manager and check the website bindings, default it is listening on all IP but this is not the behavior that I want I want a NLB. So we need to set the website on the NLB IP configured earlier.  When Having multiple IP on the NLB pick the right IP!

imageimageimage

Remember this you need to do this on all the Webservers!

image

For creating a NLB farm you can use my script that is posted in the TechNet gallery.

 Create a Windows Server 2016 NLB Network Load Balancing farm https://gallery.technet.microsoft.com/Create-a-Windows-Server-05a13f14

Upgrading to Windows Server 2016 Failure or Success #Windows2016 #Server #CloudOS   2 comments

How ever Windows Server 2016 is supporting Rolling Upgrades Upgrading to Windows Server 2016 but this is only for a Cluster.

For other Servers you can upgrade your server or better reinstall. Bet you all choose for the Clean install.

image

Installation is the basic concept of getting the new operating system on your hardware. Specifically, a clean installation requires deleting the previous operating system. For information about installing Windows Server 2016, see System Requirements and Installation Information for Windows Server 2016. For information about installing other versions of Windows Server, see Windows Server Installation and Upgrade.

https://technet.microsoft.com/en-us/windows-server-docs/get-started/supported-upgrade-paths

Well in this case I try a sample Domain controller. This has several roles and is migrated from 2008<>2012<>2012R2 and now to 2016 so is this the best option ? Well this DC has ADFS,CA,had Identity Management for UNIX. So a not so typical DC.

image

So I removed all unneeded components like ADFS and the Identity Management for UNIX was not available on my DC. ( did not make a screenshot )

no mater what I did I need to deinstall the components the following article was a help https://msdn.microsoft.com/en-us/library/cc731178(v=ws.11).aspx

Well not totally the message was still there reboot / showdown nothing. Was there anything stuck on this DC ?

Well this the DC is getting replaced the fastest way Clean install. I build a new DC with Windows Server 2016 installed the AD role on the server. Important is moving the FSMO roles.

After I did a Forest prep and Domain prep I joined the Server to the domain.

Finding the FSMO roles

netdom query fsmo

image

Moving the Roles can done in the old way but also in powershell

Move-ADDirectoryServerOperationMasterRole -Identity “Your-DC” -OperationMasterRole SchemaMaster,RIDMaster,InfrastructureMaster,DomainNamingMaster,PDCEmulator

After I moved the FSMO roles and rebooted and Updated both DC’s I thought lets find why the upgrade won’t work on the original Domain controller.

After I started the upgrade I was shocked that the Upgrade had no Issues anymore. Leasons learned In case of Upgrading the Domain controller and you have some Issues : create a new DC and Join move the FSMO roles reboot the DC’s and try again if you really need this DC. but a Clean OS install is much faster and better but you will need to install some apps again or tools. maybe this is a good time to automate this.

How To use Windows Server 2016 Hyper-V VMGroups #winserv #Cloud #Hyperv #Windowsserver2016   Leave a comment

Suppose you have some Hyper-v Machine’s and running Azure Stack and the VM’s have all follow up codes and there are say 1000 DC and 2000 File servers etc this is a hard time to manage. So there for in Windows Server 2016 you can work with VMGroups. So you don’t have to list all 11151 VM’s on the Hyper-v server to manage a VM you can create groups and manage the Group.  multiple changes in one simple action.

All these options are PowerShell only there is no GUI or indication that there is a configuration active So be careful when you are starting with this.

New-VMGroup

Just a Quick selection how many VM’s are on this host.

New-VMGroup

VMGroups how does this work and how can I use it.

First check what commands we have Add-Get-New-Remove

Get-Command *vmgroup* to get a listing on the Group commands

New-VMGroup

VM groups comes in two types

  • VM collections: which is a logical collection of VMs on which you can take some actions at the level group.
  • Management collection: is a logical collection of VM collection groups and or mixed groups

VM Groups can be used when doing the same task to multiple VM’s say backing up Shared VHDX or setting up Replication or start stop VM’s . Its also provide easy management of multiple VMs when using VM Collection Groups.

First we need to create a new group

In this sample I’m using several groups as I have a lot off VM’s running on this Hyper-V server they are divided in several groups.

as the –Verbose will show you some text on what the command did.

# Create new VM Group
New-VMGroup -Name AstackDC -GroupType VMCollectionType –Verbose

New-VMGroup

Now that the Group is created we can add members to the group. as Currently there are no members in any group

Get-VMGroup |SELECT NAME,VMMEMBERS

New-VMGroup

As I have a lot off VM’s with all follow up numbers if need to combine them and not picking them by hand.

First my first 20 Machines are all tenant Domain controllers I create a VM group to combine all these DC’s

$AstackDCten=1..10 | % { Get-VM -Name azurestvm0$_}

New-VMGroup

#Add VMs to the VM Collection Groups

$AstackDCten=1..10 | % { Get-VM -Name azurestvm0$_}
Add-VMGroupMember -VMGroup (Get-VMGroup AstackDCten) -VM $AstackDCten
Get-VMGroup AstackDCten

New-VMGroup

Suppose you want to do maintenance on the DC’s you could create a A and B group and during patching you reboot A first and then B.  It is all possible.

#View the membership of the groups
Get-VM | ft Name, Groups -AutoSize

image

Get-VMGroup AstackDC

As you can see there are now multiple ways to show the VM’s  Say you have a test lab or during maintenance you want to stop some VM’s

#Perform actions on the group as if it were a VM
Stop-VM -VM (Get-VMGroup AstackDC).VMMembers
Start-VM -VM (Get-VMGroup AstackDC).VMMembers

Or you can setup a VM replication

Enable-VMReplication -VM (Get-VMGroup AstackDC).VMMembers –ReplicaServerName SOFS08 -ReplicaServerPort 50001 -AuthenticationType Kerberos -CompressionEnabled 1 -ReplicationFrequencySec 30 -AutoResynchronizeEnabled 1  –recoveryhistory 4 –vsssnapshotfrequency 4

Or check the memory and upgrade all VM’s in a group Plenty of options there.

 

#Create combined VM Management Group with AstackDC and AstackDCten

New-VMGroup -Name MgmtDCGroup -GroupType ManagementCollectionType

image
Add-VMGroupMember -VMGroup (Get-VMGroup MgmtDCGroup) -VMGroupMember (Get-VMGroup AstackDC)
Add-VMGroupMember -VMGroup (Get-VMGroup MgmtDCGroup) -VMGroupMember (Get-VMGroup AstackDCten)

Get-VMGroup -Name MgmtDCGroup

image

#Create VM Management Group with MgmtDCGroup and AVMDCWAPGroup to show nesting

New-VMGroup -Name MgmtDCFullGroup -GroupType ManagementCollectionType

Add-VMGroupMember -VMGroup (Get-VMGroup MgmtDCFullGroup ) -VMGroupMember (Get-VMGroup MgmtDCGroup )
Add-VMGroupMember -VMGroup (Get-VMGroup MgmtDCFullGroup ) -VMGroupMember (Get-VMGroup AVMDCWAPGroup )
Get-VMGroup MgmtDCFullGroup | Select-Object -ExpandProperty VMGroupMembers

image

As you can see with a view VM’s this is not that complicated but with a large amount of VM’s this can rapidly grow to a uncontrolled situation. As this must be done from PowerShell use the ISE if you do something wrong you can easily delete the groups and add them again and think about the group names and members before you start

VM Collection Groups are fairly simple. They maintain a membership of virtual machines, those VM groups contain actual VMs.

Management Collection Groups

The Management Collection Groups, on the other hand maintain a membership of VM Collection Groups. Please note that VMs cannot directly belong to the membership of a management collection.

The group name for VM and Management collection groups might be confusing a little bit, in order to differentiate between both groups, we can refer to the collection group using the first name “VM” (membership of individual virtual machines), and “Management” “MGMT” (membership of VM groups).

VMGROUP Removal

If you want to delete the management collection group, you need to remove first the VM groups from the management collection and then delete the management group.

image

The following PowerShell script will allow you to do so:
# Remove VM Group Members from Management Collection
Remove-VMGroupMember -VMGroup (Get-VMGroup MgmtDCGroup) -VMGroupMember (Get-VMGroup AstackDCten) –Verbose

Remove-VMGroupMember -VMGroup (Get-VMGroup MgmtDCGroup) -VMGroupMember (Get-VMGroup AstackDC) -Verbose

image

remove-VMGroup -Name MgmtDCGroup –Verbose

So always remove the nested Groups first there is no Force option that deletes the whole Tree at once.

image

When there are no nested groups or VM’s in the group you can delete the Group.

image

VM management is getting more complicated as the VM’s are growing and central management is great and now with the VMgroups you can easy manage a large amount of VM single handed.
