Cluster Manager Version in RSAT Tools

$

0

I'm running Windows 10 and have a cluster built with 3 Windows Server 2008 R2 nodes

I installed RSAT Tools on my laptop, but when I try to connect to the cluster through the Failover Cluster Manager on my laptop I get an error saying:

"The cluster to which you are attempting to connect is not a version of the cluster supported by this version of Failover Cluster Manager."

I checked and the current version of Failover Cluster Manager that I am running is version 10. What version of Failover Cluster Manager do I need to run in order to connect to my cluster, and where can I get that?

I can connect to the cluster from the member nodes just fine.

Hi guys,

I have a Physical Server with Windows Server 2012 Core Standard with Hyper-V Role. A virtual machine hosted has three physical disk connected. After an unexpected shutdown I had to remove the SCSI Physical connected disks, because an start error. After that, the VM start without problems. But when I try to attach again any Physical Hard Disk to ISCI connector option is not available:

Already turn the disk offline basic...

Also try with PowerShell: 

Get-disk

Add-VMHardDiskDrive -VMName XYZ -ControllerType SCSI -DiskNumber DISK Number

But, I get this "Not Found":

I aprreciate very much your help.

Hyper-V File Server setup recomendation

$

Hi All,

We have a 2 node Hyper-V cluster running windows server 2012 R2. A third Hyper-V server is located at our DR site that is not part of the cluster however it is using Hyper-V replication for VM between our primary site. The backend connects to a SAN via iSCSI and we are using CSVs as storage for the VMs.

We have built a VM running windows server 2016 that hosts our company documents and user profiles. The company documents and users profiles reside on seperate .VHDX files. These sit on seperate LUNS presented to the hosts and configured as CSVs. The server is configured for Hyper-V HA, and we are using DFSR to replicate company documents and user profile data. The data is being replicated to a VM at our DR site running another VM with the same specs.

Since we have a 2 node setup setup in our production site, is there a way i can build a second server so i can redirect the users to point the the second server seamlessly (no downtime) so i can patch one of the systems?

Is there a way to do this so i don't have to have duplicate data on each of the VM's?

Thanks in advance.

Windows 2012 R2 Hyper V to Windows 2008 R2 Hyper V

Hello all,

  My newness to the world of Servers can be encapsulated within the last 10 months.  You can say this responsibility has been tossed onto my plate. I have learned a lot since then and manage to find solutions to my problems by "Google Searching" my way out with the Offline network that I now maintain.  I now seek help because I am working backwards in software. 

 I "inherited" a Windows Server 2012 R2 that has a VM Ubuntu 16.04 Server on it.  On Ubuntu was created a intranet Web Server.  What I am wanting to do is copy the Ubuntu Server with the Web Server content and put it on Windows Server 2008 R2 on its Hyper-V. 

How can I accomplish this task?  WS 2012 R2 has the replication feature, but WS 2008 R2 does not. I don't want to export it either as I want the web server on both. Could I use a 3rd-party software to copy the VM Ubuntu?  What would you recommend?  Any other suggestions or ideas?  

I forgot to mention, these two servers will be on separate networks once I am done and will not be able to communicate to each other for security purposes.

Thanks for your help.


Hyper-V 2019 - Guest VM's shutdown unexpectedly

$

Hi,

Since upgrading my Hyper-V servers to Windows Server 2019, including KB4471332 from last night, my guest VM's do not power down on restart of the 2019 host.

I can confirm integration components are as up to date as possible, and each guest is configured to shutdown when the host restarts.

Each guest gets the "Why did I shutdown unexpectedly message".

The even viewer yields the following all within 30 seconds of restarting the host:

Shut down physical computer. Stopping/saving all virtual machines...

'ADFS' failed to perform the 'Shutting Down' operation. The virtual machine is currently performing the following operation: 'Shutting Down'. (Virtual machine ID 0CFDF648-EE9D-4141-9EBD-9A6D911C3442)
'ADFS' failed to shut down. (Virtual machine ID 0CFDF648-EE9D-4141-9EBD-9A6D911C3442)

The Update Orchestrator Service service terminated with the following error:
This operation returned because the timeout period expired.

Failed to restore configuration for port 59229EE2-C880-4BF2-9849-89A21EC17772 (Friendly Name: ) on switch 300C0E17-E123-4182-BE62-AAD1860BE841 (Friendly Name: ), status = Object Name not found..

Everything is configured as it was on the 2016 Hyper-V host.

The message ADFS failed to shut down because it is shutting down seems terribly odd to me.  Of course its shutting down, just need the host to wait. (Yes the registry is set to 120 as the default time for the host....)

Fairly simple to recreate....just spin up a 2019 server, install Hyper-V role, throw in a VM and test.

Any help would be appreciated, but my money is on it being another bug.

Cannot delete checkpoints

Hi,

We have a Windows 2012 R2 VM with checkpoints which we are unable to delete and getting the below message. Now the only way to fix this is to export the VM to a different location and then import it again. Will it merge the VHDs with checkpoints or what is the proper way to get rid of check points without losing the data?

We have built a new 3-node Hyper-V Server 2019 cluster with shared SAS connected storage.

Guests servers are running fine (Windows 2019 Standard), but I am unable to get the Failover Cluster Manager to monitor the guest services.

Error message is "Unable to retrieve the list of services from the virtual machine XXXXX."

  • Guests, hosts and Failover Cluster are int he same subnet
  • All are in the same Active Directory
  • I'm using a domain admin account
  • Virtual Machine Monitoring firewall rule is enabled

Any ideas what I'm missing to get this working?


Cannot Access Newly Created Hyper V

I just installed a new VM on a new machine with Windows Server 2016. When I try to access the VM I get the error message:

Remote Desktop Connection: An authentication error has occurred (Code:0x80004005), Remote Computer: Server

then after I choose the OK button I get:

Cannont connect to the virtual machine. Try to connect again. IF the problem persists, contact your system administrator. Would you like to try connecting again?

There are 2 buttons "Connect" and "Exit". If I choose Connect the same message appears again.

I have tried numerous solutions including deleting and resetting up a new VM, restarting server, changing Group Policy. None seem to work.

Any other suggestions are greatly appreciated.

Hello guys, i want to simulate a site to site VPN connection,  on hyper-V in my laptop, and i want Clients to be able to connect with VPN to the Sites

could you provide me some tips about how to build it? 

- Do i need to have VPN server in each LAN? 

- Would you set the VPN to have 1 NIC connected to the LAN's switch and another NIC connected to the "WAN" switch? 

or there's a different way of doing that, 

any tips and guidance would be perfect!

Thanks

Live Migrations No Longer Working After January 2019 Updates

$

Thanks for the reply Michael

We have found out that the problem is actually caused by the January update (KB4480963 Monthly Rollup) This affects AMD Bulldozer Family 15h, AMD Jaguar Family 16h, and AMD Puma Family 16h second generation microarchitecture one of which our hosts use,  and is solved, (we must verify) with KB4490512.

However KB4490512 requires a reboot;
We are unable to live migrate between hosts using SCVMM or Failover Cluster Manager although we can cold migrate.
We have 400 plus live VMs over 40 plus hosts and could really do with a solution that would not involve us powering off our VMs

Windows Server 2019 standard with REFS file system - Stand alone Hyper-V server

$

Hello,

I am planning to deploy a stand alone Windows Server 2019 standard Hyper-V server with ReFS file system. This is primarily for windows server virtualization .The idea is to take benefit of new de-duplication feature of Refs.  I have following questions around this deployment

1) Is ReFS supported on stand alone Hyper-V deployment? It will have only local disks.

2) Is ReFS de-duplication supported on standard edition of windows server 2019?

3) any known limitation?

Creating Linux VM's using a kickstart script.

I need to build out some Linux VM's (OL-7) and don't want to manually add the networking/config info. There is already repository setup for bare metal linux hosts that will do what I want, but I'm not sure how to add the kickstart file to a new VM that is booting up. My guess is to connect the virtual floppy, but I'm not sure where/how to create the virtual floppy using the correct format Hyper-V/Microsoft wants.

Has anyone done this before or have a good tutorial URL for this?

Thanks

DFS and resilient FS options

$
0
0

Morning

I have a 4 node Server 2016 Hyper-v cluster running on a Dell VRTX (Built in shared storage), this provides a number of VM's including a few File servers. 

We use DFS namespace for most of the file servers, simply to make it easier as servers get changed, upgraded, renamed etc.

Lets take the example of FS1 (File server1), it has a DFS namespace with a number of folders/shares under it.

I want a solution to have a FS2 that also shares the same DFS name space, so that we can do maintenance on FS1 while users continue to work. Then maintenance on FS2 while FS1 is back up.

What options are available with our Hyper-v Cluster to achieve this?

One of the other File servers is simply for users H: drives, a share for each user exists, for example \\FS3\fred$.

What options do we have for a 2nd server for this, to allow the same kind of maintenance?

This cluster all exists on one site, in one rack.

Thanks in advance for suggestions and ideas :)


Cannot live migrate 2 of 12 VM's in FCM on Server 2016

Cannot live migrate 2 of 12 VM's in FCM, when trying to live migrate these 2 VM's they get to around 48% and then the live migration stops. We've tried many things to resolve this, I'm just wondering if we've missed something.


Troubleshooting steps taken:

1. Settings > Management > Name, check for Notes in the properties 
2. Check for files or lock folder in C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines 
3. Adjusting VM migration timeout using HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft System Center Virtual Machine Manager Server\Settings\LiveMigrationTimeoutSecs 
4. Verifying no other users are canceling live migration
5. Verifying the cluster nodes have identical hardware 
6. Attempting to migrate to a different node
7. Running the Cluster Validation Wizard within the FCM to test the cluster
8. Questioning if underlying issue appears to be not with the cluster itself, but the VM 
9. Verifying cluster host live migration success for other VM's
10. Uninstalling Veeam to verify Veeam is not causing issues during backup
11. Attempting to live migrate VM with PowerShell 
12. Verifying BIOS revision is same on all 4 nodes 
13. Verifying Jumbo packets are disabled on all NICs. 
14. Confirming where VHD resides and if permissions are correct on location
15. Attempting storage only live migration, which was successful
16. Moving MRT & RCD files and attempting to live migrate which was not successful
17. Trying to live migrate after a successful quick migration
18. Tried enabling Processor compatibility mode
19. Verifying patch level of cluster nodes
20. Check for XML file cache at C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines Cache 
21. Editing Registry for NetworkBufferCount at HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization\Migration 
22. Considered disabling Hyperthreading but cannot be done
23. Verified VM's do not use shared VHD Sets 
25. Verified vCPU and vRAM among guest VM's 
26. Verified Processor > NUMA, does "Maximum amount of memory (MB)" matches the same setting under Memory > RAM or Memory > Maximum RAM

CPU-Usage

$

Hello,

yesterday i wanted to understand CPU-Usage-Display from VM's and Hypervisor-Hosts and i red a lot of regarding stuff.

First question:

A lot of posts say, that the display in the taskmanager does only show the usage of the host-OS vCPU, but not of the physical. While i checked the CPU-Usage, i got another picture! The Taskmanager of the HyperV-Host seems to show the exactly same values as here the "logical CPU of hypervisor" (i am not sure if microsoft made a mistake in the translation, was hard to find the counter because it's listed under L what i didnt expect), that you can see here with the fat red line.

So i am wandering if microsoft changed the behavier of the taskmanager in Server2016 (what is the System i made this tests on), or if i misunderstood something!

EDIT/UPDATE: After a recently login to a Server 2012R2 iv'e seen a different behavier - here the TaskManager of the HyperV-Host indeed shows not the CPU-Usage of the Counter "logical CPU" - so i can give the answer to my own question: it seems as M$ changed the behavier of the TaskManager somewhere within Server2016 release! Maybe this helps not only me in the future, to be less confused within various POSTS in Forums (also far beyond 2016), that told us, that the TaskManager does NOT show the CPU-Usage of the  physical CPU - while it was right for 2012/R2 it is wrong for Server2016.

while i recorded this graphs, i started CPU-Burn.

within the first peak of 100% CPU-Usage, i ran CPU-Burn on the Hyper-V-Host, so the blue line goes to 100% and the fat red one aswell. okay, this seems to be logical.

within the second peak of 100% CPU-Usage, i ran CPU-Born on one of the HyperV-VMs, that has assigned 11 vCPU's (while the system has 12 logical cores), so it is limited to 95% what we can see within the fat line.

what i dont understand is: what does the thin red line shows? if it is the sum of all virtual cpu's it should show aswell almost 95% CPU-usage, but it just shows something like 35% which makes no sense at all to me. can somebody explain that?

last but not least, the HyperV-Manager has also a CPU-Usage display, which does not correspondent to the CPU-Usage-display inside the taskmanager of the VM, and also does not correspondent to the relative ammount of usage of the physical CPU - as far as i understand everything right and as far as i found the right counter to display the usage of the physical CPU.

i hope, someon can bring light into the dark!

Are there any legal or Eula restrictions in using Microsoft Hyper-V Server 2016 os in other purposes then to create and host virtual machine? I mean, like a third party browser can it be installed on the host os, to browse the web?
