Adding nodes to Windows Server 2008 R2 Hyper-V Cluster..

Currently we have a 3 node Windows Server 2008 R2 Hyper-V Cluster in production. There are about 3 terrabytes worth of VMs running across these nodes.
It is over-committed, so i've setup two new nodes to add to the cluster.
I've done this before in a SQL cluster but never a Hyper-V cluster.
If I don't run validation when adding the nodes, will there be downtime?
The quorum is setup for disk majority, everything is identical on all nodes that needs to be. Shared storage is recognized and ready on the new nodes. I've gone through every checklist that Microsoft has. I'm just curious if the virtual machines will go
offline on the current nodes when i add the two new nodes.
Everything is identical down to the wsus updates installed. From networking to storage everything is perfect.
I don't want to run validation as I know that'll take everything offline.

Hi,
It is recommend to run a validation test. You can select custom test. (skip storage).
When add the new node to existing cluster . it will not bring down existing VM.

How to add a cloud machine as a node to existing windows fail over cluster having on-premise node in Windows server 2008 R2

Hi All,
We have a windows fail over cluster having one windows machine on local network as one of its node.
I want to add a virtual cloud machine available on microsoft azure as another node to this existing cluster.
Please suggest how to do this?
Thanking all in advance,
Raghvendra

Before you even start working on the SQL side, you will need to create a Windows Server 2008 R2 cluster with no shared storage. You can actually test that in-house. Create a VM running 2008 R2 and cluster it with your physical (from your description,
I am assuming physical) 2008 R2 machine. Create it with a file share witness for quorum. Then configure your environment to see that it works as expected.
Once you know how to configure the cluster between physical and VM with a file share witness, build it to Azure. The location of the FSW gets to be an interesting choice. To have a FSW in Azure means that you will need another VM in Azure to
host the file share, meaning you have two quorum votes in Azure and one in-house. Or, you could create a file share witness on an in-house system, giving you two quorum votes in-house and one in Azure.
In the FSW in Azure scenario, if you have a loss of the in-house server, automatic failover occurs because two quorum votes exist in Azure. With FSW in-house, depending on the loss you have in-house, you might have to force quorum to get the Azure
single-node cluster to run. Loss of access to Azure reverses those scenarios. Neither one is optimal, but it does provide some level of recoverability.

How many licence for Windows Server 2012R2 in hyper-v cluster base on free Hyper-V Server 2012R2

Hi
I build cluster consist 4 nodes (2 procesors, 4 core per procesor=8 virtual processors per node). I installed free Hyper-V Server 2012 R2 on each node and created cluster.
I've got one Windows Server 2012 R2 Standard. How many VMs (with Windows Server 2012 R2 Standrard as OS) can I run on this cluster using this DVD? 1, 2 or none?
Thank you in advance
Tomasz
Kind Regards Tomasz

The detail here is this:
You are asking about the 'virtual instance granting' license.
- this only applies if Windows Server is installed on the bare metal with the Hyper-V Role added. (regardless of the edition)
- this only applies to licensing, it does not limit the number of VMs that you can run.
- If there is a cluster, all nodes should be the same edition to remove any licensing ambiguity.
This is strictly OS licensing for the VMs and has absolutely nothing to do with how many VMs you can run:
Most likely your hardware will run out of physical resources before you reach the maximums outlined here:
http://technet.microsoft.com/en-us/library/jj680093.aspx
If you have a cluster - there can be a maximum of 8,000 running VMs
If you have individual Hyper-V Servers there can be a maximum of 1,024 running VMs
Do the math - you would need a minimum of ~8 cluster nodes to touch that 8,000 number. But as you add nodes, you don't add HA VM capacity. But you can run a combination of HA and non-HA VMs up to a the maximum of 1,024 running VMs per node.
In other words, mix and match if you want to push the boundary.

Windows server 2012 Datacenter Hyper-V Cluster -- Failed to validate Operating System Installation Option?

Hi I have a 4 node Windows server 2012 Hyper-V cluster. When I try to run a cluster validation report, everything else is fine but it fails at validate the Operating System Installation Option step. I did some research but couldn't really find any solution.
Anyone knows how to pass this test? Thanks.
Here's the error I get when run the test:
An error occurred while executing the test.
The operation has failed. An error occurred while getting the operating system installation option for node "server1"

Hi JasonLiu2002,
Please post the original error information, the current information is so wide that difficult to determine where may have issue and please offer more information about your
server configuration, you can refer the following article to prepare your cluster environment first.

Issue with jython : javaos.py : Platform detection for Windows Server 2008

Hi,
While trying to execute a Windows batch file via ODI using Jython, the jython code fails with a 'Failure to execute command' error, and the command itself is appended with 'sh -c "<batchfilename>". The javaos.py file does not have 'Windows Server 2008' in the list of osTypeMap values, and therefore defaults to posix, which further adds the string 'sh -c' to the command and tries to execute the batch file under a unix style 'shell'. Adding the string 'Windows Server 2008' to the osTypeMap resolves the problem. However we are looking for possible alternate solutions.
The question right now is:
. Is there an updated javaos.py version available which supports Windows 2008.
. Does the latest ODI installer include jython support for Windows 2008

Hi,
I believe you mean the Active Directory Logs not the DNS logs, because these are necessary to startup a domain controller, because the AD database depends on these logs.
So if you have AD logs on a different partition and that is encrypted with Bitlocker you could probably automatically unlock it.
So you did not encrypt OS partition because the server does not have a TPM fully compliant chip ?
manage-bde /?
manage-bde -autounlock -enable Driveletter:
But you have to be able to boot server normal mode I am not sure if the command can be used in DSRM mode.
Below are some links that might help:

Active-Passive Failover cluster in Windows Server 2008 R2

Hi,
As per the client requirements, I build an active-passive Oracle 11g R2 database cluster in Windows Server 2008 R2.
(Used Microsoft cluster as Client don't have Fail Safe licence)
As per the configuration, I follow the below mentioned steps:
a)OS vendor configured Active-Passive Windows Cluster
b)Installed Oracle 11g R2 on both the nodes with same ORACLE_HOME name
c)Create Listener and configured it with cluster IP in Node1
d)Create Database from Node1. Physical files location are all in Storage
e)Create Oracle Service with the same name in the 2nd node and copy all the files like spfile,tnsnames.ora,listener.ora,password file to Node2
f)Configure Listener with the same Oracle SID.
g)Test database failover from Node2 with Listener registration
h)Open the Windows Failover Manager to configure the Oracle Database and Listener Service in the Cluster Group
Now I am facing problem by moving Cluster Group movement. Whenever trying to moving the group, Listerner service is not getting up by Cluster Manager as quorum is not included in the group and that quorum disk is not moving in the failover node with the Oracle Cluster Group. As per my understanding Quorum having information of Cluster IP which has been configured with Listener.
But when I am shutdown one node, then in the other node all the resources successfully moving and cluster able to online all the resources. I guess at that time Quorum is also moving and thus cluster can able to make Listener online.
Please suggest how to resolve this issue. Means how can I make Listener up instead having any dependencies with Quorum in the fail over node?
Thanks a lot for your help.

hello
I was going through your post and i am also doing the same thing here at our organisation for Oracle 10g R2
Can you pls send me any docs u r having for configuration of Oracle in windows clusters .
And, can you pls elaborate on this point
e)Create Oracle Service with the same name in the 2nd node and copy all the files like spfile,tnsnames.ora,listener.ora,password file to Node2.
Pls send me the details at [email protected] or you can contact me at 08054641476.

What is the easiest way to replicate(backup) a VM whose host is Windows Server 2008 R2?

I have a Windows Server 2008 R2 Hyper-V Manager and I have a Domain Controller as VM (which is running Server 2012 R2) and I would like to enable replicationfor this VM(I want to back up the Domain Controlloer).
Could you please tell me the easiest way of doing this?
Thanks,
Radu

Hi, Radu,
From my perspective, in this case the backup/replication solution should:
Perform image-level backup, as it’s always preferable to use such method for backing up/replicating virtual machines.
Guarantee application consistency. That’s being said, not only should it backup VMs running special application in consistent (VSS-aware) mode, but also it should apply
application-specific settings to prepare each application to perform
VSS-aware restore on the next VM startup.
Support 2012 R2 platform.
We’re using Veeam for the same purposes, as it does have abovementioned functionality. Though, you can stick to whatever solution that can boast with the listed options.
Kind regards, Leonardo.

Installing Windows Server 2008 R2 any edition, On Windwos 8.1 Pro, Hyper-V?????

Hello all
Im running Windows 8.1 Pro. It has Hyper-V on it, I use it and ive been able to install alot of os on it vista, xp, linux, etc.
I got an educational copy of windows server 2008 r2 with cd key. From MS dream spark
when i try to install it on Hyper-v it always finishes the installation process and when its about to restart for the first time it gives an error of not all components where installed pls restart computer and restart installation. I do this and it just
goes on a vicious cycle of restarts and always erroring out.
ive tried re downloading the .img file from Microsoft today and when i attempt to install it again i get he same error
My pc specs are 8 gigs of ram 1600 mhz and a I5 4670k plus i have plenty of space on ssd/hdd
i set the virtual os to have 2 GB of ram and 127 GB of hd space when im configuring it in hyper-v manager
can some one help me? or has anyone had a similar issue?

Please Download Windows Server 2008R2 from Download Center of Microsoft and then test it , if it works it relate you media installation .

Mouse not working in Virtual machine (win2k3 32 and 64 bit) on Windows Server 2008 RC1 With Hyper-V Technologies

I have installed two virtual machines(win2k3 32bit and win2k3 64bit ) on Windows Server 2008 RC1 With Hyper-V Technologies (Beta) enterprise. Mouse is getting lost inside VM (using CTRL+ ATL + LEFT ARROW comes mouse control control in host OS).
Is there any setting to make mouse works? Insert Integration Serice setup Disk operation succeeds.

all credits for mike_something
The problem is that the old mousedriver is hooked to the mouse device class.
To remove this dependency, go into the registry and navigate to the key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}
Remove the value msvmmouf from the UpperFilters Regvalue.
Reboot....
tadaaa!!
If you wish you can take out the drivers completely by deleting these registry hives completely :
The driver:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\msvmmouf
The Service:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\VPCMap
The CopyHook Shell Extension: ( for folder access )
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{30C14BA C-122C-42ED-B319-1139DBF48EB8}\InProcServer32

After a reboot you can delete the "Virtual Machine Additions" folder from program files...

Unable to Install Windows Server 2012 on Windows Server 2008 R2 SP1 Hyper-V

My attempts to install are failing with a message "Windows cannot install required files. The file may be corrupt or missing....Error code: 0x800705070".
I am posting this on the Wondows 2012 Server forum but I have had exactly the same problem as described below with Windows 2008 R2 SP1.
As the title says this is on a Windows Server 2008 R2 SP1 host with all current updates. I have downloaded the ISO file from a Technet subscription file twice, once by direct download and once by the Akamai downloader. The virtual disk is connected with
the default IDE driver. I mounted both installation images as ISOs, located on a file system on the host server. I have tried installs by deleting the VM and recreating both the VM and a new virtual disk, re-using a previously created virtual disk, and
deleting the partitions in a previously created virtual disk, and executing the format command, and then attempting the install.
I have exactly the same problem trying to create a Windows Server 2008 R2 SP1 VM on the same host OS. With those attempts, I downloaded the Technet subscription iso 4 or 5 times, and burned one to a DVD which I attached to the created VM. Same
error message.
The virtual machines and virtual disks I created and used were all located on an RAID5 array, on a builtin Intel RAID controller using Intel Rapid Storage Technology software version 11.2.0.1066. The host Windows Server 2008 R2 SP1 uses this file system
but the OS is installed on a dedicated drive (C).
I had previously created a guest VM with Windows Server 2008 R2 (several months worth of updates ago) without drama.
I have spent hours reading forums and blog articles on this. A common response is to download the iso another time, and/or burn it to a DVD instead of mounting an iso image. Although I didn't do the later yet with 2012 Server, but I have done these
other steps attempting to install Windows 2008 Server SP1. The install process takes a while (not to mention doing multiple downloads). Given this seems to be a common recommended remedy, and indeed based on posts does seem to eliminate the problem is some
cases, why doesn't somebody change the Microsoft installer program so it does a thorough integrity check at the beginning of the install process?

Jeff,
After the exercise of Windows 2012 Server successfully installing (as I described above) I also successfully installed Windows 2008 R2 on Hyper-V. From my standpoint, I have eliminated the problem (which isn't the same as correcting the problem).
The answer to your specific question regarding Hyper-V support is that the motherboard I am using, an Asus P5Q, is not supported by Windows 2008 R2 because it doesn't use ECC memory, and the vendor doesn't say it supports Windows 2008. But I am sure you
know the motherboard vendors often don't test older motherboards with newer software versions. It appears that in specifying ECC memory Microsoft is trying to protect users of Windows Server from hurting themselves, not saying the software won't run.
Having said that, my suspicion in the beginning was, and still is, that it was some variable(s) left in an unknown state in the Hyper-V environment, which was why after trying to install Windows 2008 R2 several times I tried Windows 2012 which resulted in
the same error, and then encountered the same error trying to install Windows 7 on the same Hyper-V installation. The specific Hyper-V Windows 2008 R2 server had run without any operating problems for months before I started having trouble, and although it
had been quite a while since I had created VMs, that process used to work. The hardware didn't change. What changed was applying updates through Microsoft Update, and a few access control rights I changed, and at least I think, I set back to their original
value.
So in short, no, my hardware isn't supported by Windows 2008 Server. Two, your assertion that you are running the same software configuration that I am is very unlikely to be true. There are an extremely large number of things which are different between
your test system and mine, such as which Windows 2008 components are installed, what updates were installed and in what order they were installed, and what other third party software each of us is running, and between AD, and all the features, a large number
of potential differences in ACLs, options, etc. and I don't for a minute think this particular problem was caused by the underlying hardware.
I do appreciate your taking the time to try to help me, and I hope there is one thing you and I could agree on. Microsoft could pretty easily make it much easier to isolate problems. In this day and age reporting hex error codes (as opposed to doing the
table lookup in the error handling proc), and not providing more diagnostic information seems to me to be almost quaint. And in this case Microsoft can dismiss my problems on the grounds it was all on unsupported hardware. Unfortunately, I think they
are missing an opportunity to make their software better, because in my opinion what I encountered there are a set of conditions which will cause installations to fail that aren't going to get corrected.

Blue Screen Error during starting Windows Server 2008 R2 (VM on Hyper-v WinSvr2012) Using a Physical to Virtual (P2V) VHDX.

Hi There,
I'm trying to migrate one of my physical Windows Server 2008 R2 to Virtual Environment (Hyper-V on WinSvr2012).
(The original physical machine had multiple partitions on the windows HDD and 2 other boot able OSs where installed on 2 of those partitions ...) So anyhow, After heaps of trouble shooting and fixing the boot records, it finally started booting the
Windows but when it got to loading C:\windows\System32\Drivers\Classpnp.sys
and it crashed, a blue screen poped up saying "A Problem has been detected and windows has shut down to prevent damage to your computer ... ) and then system got rebooted automatically.
I have tried chkdsk, also tried copying a new classpnp.sys to replace the old one but no hope. I don't think is not a damage file issue. Not sure, but it is probably related to changing the HDD devices or SCSI/IDE controllers?
Any idea?

1. You have placed your problem in wrong forum. Address your problem to Server forum instead.
2. I do not think it is liable configuration. I have not heard about migration of multiboot HDD. Try to split it. Pay attention to better preparation. I would expect separate target VM.

Milos

Installing Hyper-v Windows Server 2008 R2 on to Windows 8.1 Pro

I downloaded a 180 day trial hyper-v Windows 2008 R2 version to my Windows 8.1 Pro system. I have 16 GB of Ram, and my system is an i7-4700HQ CPU @ 2.40Ghz. Hyper-v manager is running, and I can click action, new virtual machine, and I can
give it a name. I have chosen to install the virtual machine on my D: drive. It is an empty 400GB basic partition, except the swap file is located here (system managed). I used Generation1 for the virtual machine, and gave it a startup memory
of 2000MB, which was suggested on another website. On configuring the network connection, I left it as Not Connected - plan to change later. On connecting the virtual hard disk, I was not certain what to do between the 3 selections. Default,
Create a virtual hard disk, Use an existing virtual hard disk, or Attach a virtual hard disk later. I chose the default, "Create a virtual hard disk" because it is a new virtual machine. On Installation Options, I tried the "Install
an operating system from a bootable CD/DVD-ROM. The 180 day trial was copied to this CD. When starting the virtual machine, I received boot failed message, so I deleted the virtual machine in Hyper-v manager and associated folders on D.
I don't know what to do next? Should I try to import a virtual machine from a configuration file somehow?

You cannot install Hyper-V Server 2008 R2 on Windows 8.1 (it sounds like that is what you are trying to do).

You can install Server 2008 R2 in a VM. Attaching the ISO to the VM and booting should work just fine - or download an evaluation VHD and then attach the evaluation VHD to your VM and boot.
