Two VM's in one role - Failover cluster

Hello,
In my 2 node Hyper-V 2012R2 cluster I had 2 VM's, DC01 and APP01.
Today, I only saw DC01 in the Roles list at the Failover Cluster Manager. After a while I found APP01 under the Resources for DC01. What is happening here, and how can I revert it?

APP01 is down.
You should have 1 VM per Clustered Role.
In Server 2012 R2, it's not supported to have more than 1 VM per Clustered Role.

Selecting VHDx as storage for File Server Role (Failover Cluster 2012 R2)

Is it possible to select an already existing (offline) VHD or VHDX as storage when creating the "File Server" role? Reason I want to do that is because I already have a file server setup as a virtual machine and causing issues so my company
decided to make the change towards a File Server role.
Thank you
David

Hi David,
Do you mean you configured it to file server failover cluster via "High Availability Wizard" ?
I think you need to choose a shared volume between two nodes to achieve high availability .
Please refer to following link :
http://technet.microsoft.com/en-us/library/cc731844(v=WS.10).aspx
If you do not select a shared volume , I think there is no difference than sharing a mounted VHDX file on a standalone file server .
I would suggest to copy these files to CSV and share them .
Hope it helps

Very Strange Network Issue With Two Guests on 2012 R2 Hyper-V Failover Cluster

Hi all. We're having a odd issue with two guests on our 2012 R2 failover cluster.
In a nutshell, if we shutdown a particular server (I'll call it Server A) another totally different server (Server B) on the same node loses it's network connectivity to the domain. If we start server A back up, network connectivity returns on server B.
At first I thought server A might be running a service that was somehow linked to server B, so I decided to disable server A's NIC. Interestingly, that had no affect on server B's connectivity.
The next step I tried was pausing server A and again, no adverse affect on server B's connectivity.
Next step was to live migrate server A to another node. This action did
cause server B to lose its network connection.
One other clue is that if I ping server B from either of the Hyper-V hosts in the cluster, I never lose network connection to server B.
So I would suspect this is some network issue on the cluster, but I'm kind of at a loss where to go from here.
Has anyone seen this behavior before or does anyone have any troubleshooting suggestions I can try?
Thanks!
George Moore

Hi Sir,
I'v never seen this before .
>>Next step was to live migrate server A to another node. This action did
cause server B to lose its network connection.
They are connecting to same virtual switch ?
First please run cluster validation to check if there is any error .
If it is ok , please try the following items for troubleshooting :
1. shutdown serverA serverB
2. then add another virtual NIC for serverB
3. start server B check if the issue happens to both "old" and "new" virtual NIC .
In addition , you can live migrate both A and B to another node , then try to live migrate A to the original node .
If the issue persists , I would suggest you to remove that virtual switch on both nodes then re-create them .

Elton Ji

Windows server 2012 failover cluster error: Cluster resource 'Virtual Machine Configuration ... of type 'Virtual machine configuration in clustered role ... failed.

I have two windows 2012 host server that are clustered using windows failover cluster feature. Each server is hosting four VMs. When migrating from Host2 to Host1, the migration failed with the following error:
Cluster resource 'Virtual Machine Configuration SCPCSQLSRV01' of type 'Virtual Machine Configuration' in clustered role 'SCPCSQLSRV01' failed. The error code was '0x569' ('Logon failure: the user has not been granted the requested logon type at this computer.').
When this happens, the VM that I was migrating can no longer be started even on the original host. The only remedy is to restart the host server.
Any suggestion on resolving this problem?
Thanks
Ikad

Thanks. The article referred to above gives the solution to my issue. There is a group policy that is applied to the OU where the host servers were placed. Doing gpupdate /force temporarily removes the problem. Unfortunately the NT Virtual Machine\Virtual
Machines account is a special account that cannot be added like other accounts and granted the log on as a service right. The thread
http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/d56f2eae-726e-409a-8813-670a406593e8 contains how it can be added which is by creating a group and running the command
Net localgroup VMTest “NT Virtual Machine\Virtual Machines” /add
to add it to a local group VMTest. VMTest is then assigned the right to log on as a service.

Failover cluster File Server role best practices

We recently implemented a Hyper-V Server Core 2012 R2 cluster with the sole purpose to run our server environment. I started with our file servers and decided to create multiple file servers and put them in a cluster for high
availability. So now I have a cluster of VMs, which I have now learned is called a guest cluster, and I added the File Server role to this cluster. It then struck me that I could have just as easily created the File Server role under my Hyper-V
Server cluster and removed this extra virtual layer.
I'm reaching out to this community to see if there are any best practices on using the File Server role. Are there any benefits to having a guest cluster provide file shares? Or am I making things overly complicated for no reason?
Just to be clear, I'm just trying to make a simple Windows file server with folder shares that have security enabled on them for users to access internally. I'm using Hyper-V Core server 2012 R2 on my physical servers and right now I have Windows
Server Standard 2012 R2 on the VMs in the guest cluster.
Thanks for any information you can provide.

Hi,
Generally with Hyper-V VMs available, we will install all roles into virtual machines as that will be easy for management purpose.
In your situation the host system is a server core, so it seems that manage file shares with a GUI is much better.
I cannot find an article specifically regarding "best practices of setting up failover cluster". Here are 2 articles regarding build guest cluster (you have already done) and steps to create a file server cluster.

Ghost VM resources under failover cluster manager roles

Hello, everyone,
I had a Windows 2012 R2 hyper-v host with few VMs running on it. I deployed a second host, and using SC VMM created a failover cluster. Also I added a shared cluster volume and migrated all VMs to the shared storage using SC VMM console. In
the process I also checked the checkbox to make the VM highly available. Everithyng worked fine.
Now when I look in to Failover Cluster Manager console I see some "ghost" vm roles. Their names are correspondend to the names of the running VMs, which I also can see in the console. For example I have vm HDCADC01, there is another
role in the console "SCVMM HDCADC01 Resources", the status is off, settings are empty.
Does anyone knows what are these resources? Is it somekind of glitch during the migration? Is it safe to remove them?
Thank you,
Jamal.

Where should I run this command?
On my VMM server Update-clustervirtualmachineconfiguration command complains that The cluster services is not running.
On the one of hyper-v server, cluster nodes, "get-vm -name hdcadc01" returns "Get-VM : A parameter is invalid. Hyper-V was unable to find a virtual machine with name hdcadc01". The same result is when I used "ghost" resources name.

Failover Cluster - GHOST VMS / ROLES

I mean Ghost as in mysterious non-existent machine, not the old Norton program. I've periodically had random cluster crashes, mainly due to my own negligence. 99%
of the time everything comes back up normally. However periodically a machine will have very strange symptoms that i'm unable to resolve. The only resolution I've found is to create a new VM and link to the the old VHD. A description of the
machines with this issue:
Shown in Failover Cluster role as Running but cannot Connect, turn off, shutdown, etc.
Login to Host machine for the VM and open Hyper-V Manager the machine does not exist. The only place this machine seems to exist is in Failover cluster.
No details available on the Summary Tab, machine doesn't actually appear to be running despite what the console says.
Under the resources tab for that Machine is shows the VM as running, but the VM Configuration as failed.
Unable to bring the configuration back online. Error is "The group or resource is not the correct state to perform the requested operation"
I've seen other vague areas about null context pointers or something alone those lines. I've tried researching the users methods to no avail. How can I fix these? Or at least remove them when i've recreated the machine.

Hi,
Unfortunately, the available information is not enough to have a clear view of the occurred behavior.Could you provide more information about your environment. The server version of the problem on, when this problem occurs the system log record information,
screenshots is the best information.

How to recover from accidental VM role removal in Hyper-V Failover Cluster Manager?

Hello
My VMs are still available in Hyper-V Manager but they are no longer available in Cluster Manager. I am curious if there's a way to move them back into the Failover Cluster Manager while retaining their GUIDs?
I know I can manually create a new VM and add the existing VHD but that process recreates a new GUID causing the VM to regard the stuff I wanted as old.
I have tried to follow
http://blogs.technet.com/b/heyscriptingguy/archive/2013/10/14/recovering-virtual-machines-in-hyper-v-server-2012-r2-part-1.aspx but I am curious if there's a faster way to do this without becoming a scripting genius overnight.
Thanks,
Prince

Thanks for the reply but that does not help.
I am not looking to move my VMs to a remote Host but rather looking to repopulate the fail-over cluster manager with the existing VMs in Hyper-V Manager. In a sense, I am looking to reuse the existing GUID without creating new ones.
Again, my VMs are alive in Hyper-V Manager but are currently not available in Failover Cluster Manager.
Any scripting assistance will be greatly appreciated.
Thanks,
Prince

Windows 2012 Failover Cluster - File server role (vCO)

Hi,
I wonder if anybody can shed some light on a query i have.
A windows 2012 failover cluster will be built in AD domain example.uk. Cluster File server roles will be created and will reside in this domain also.
We also have a requirement to run a cluster file server role in the child domain off secure.example.uk. Is this possible? or do the file server roles and related vCO's have to reside in the same domain as the cluster (CNO).
I know the CNO can be used to create the VCO but could a prestage a VCO in the child domain of secure.example.uk.
Mark

Hi Mark,
By default CNO will create
VCO automatically in default domain computer OU, we generally use the
KISS principle to place the CNO and VCO to the same OU, and as far as I know there no known design document indicate the VCO can be placed in different domain, therefore I suggest you place the CNO and V CO at same OU.

Server 2012 R2 Running Failover cluster role on Domain Controler

I absolutely need to have Domain controller running failover Cluster node,
we have been doing it in 2008r2 and there are documents from Microsoft stating it is possible but not recommended
but the document is for 2012, I am running 2012r2
I can install failover clusting role on a 2012r2 server and from a Member node install the cluster but when I need to add the nodes that are Domain controller they thry to add but then they timeout after 5 minutes, then they delete the node that was try
to add and clean up
I have tried the CNO record and try to install DC befor and after Cluster role,
HELP
thx

Not supported, see this KB:

Guest two node Failover Cluster with SAS HBA and Windows 2012 R1

Hi all, i have two IBM x3560 brand new servers with V3700 IBM Storage. The Servers are connected to the storage through four SAS HBA adabters (two HBA's on each server). I want to create a two node guest Fileserver Failover Cluster. I can present the
LUN's to the guest machines, but when i 'm running the cluster creation wizard it can't see any disk. I can see the disks on disk management console. Is there any way to achive this (the cluster creation) using my SAS HBA presented
disks, or i have to use iSCSI to present the disks to my cluster?
Thank you in advance, George

1) Update to R2 and use shared VHDX which is a better way to go. See:
Shared VHDX

2) If you want to stick with non-R2 (which is a BAD idea b/c tons of reasons) you can spawn an iSCSI target on top of your storage, make it clustered and make it provide LUs to your guest VMs. See:

3) Use third-party software providing clustered storage (active-active) out-of-box.
I would strongly recommend to upgrade to R2 and use shared VHDX.

Can a SQL Server Failover Cluster Instance (FCI) be Implemented Between Two Hyper-V Hosted Virtual Machines?

I haven't had the opportunity to implement a SQL Server Failover Cluster Instance (FCI) for over 10 years and that was done with two physical, identical database servers way back in the day of Windows Server 2003 and SQL Server 2000 (old school).
Can a SQL Server 2008 R2 Failover Cluster Instance (FCI) be implemented between two Hyper-V hosted virtual machines? The environment in question already has Windows Server 2012 R2 Hyper-V hosts in place, so I'm just looking to see if this is even
possible and/or supported when utilizing virtual machines.
The client in question is currently using SQL Server 2008 R2 instances running on Win2008R2, Win2012, and Win2012R2, but I'd also be interested how this can be done or not with SQL Server 2012 or 2014 as well. Thanks in advance.
Bill Thacker

Yes, it can be done with Hyper-V guests. In fact, with Windows Server 2012 R2 Hyper-V, guests can use the Shared VHDX feature for shared storage used by Windows clusters. The guests can run Windows Server 2008 and higher provided that the Hyper-V Integration
Services are installed to support Shared VHDX. The only challenge here is making the Hyper-V hosts highly available as well, running it on WSFC.

Cannot migrate VM in VMM but can in Failover Cluster Manager network adapters network optimization warning

I have a 4 node Server 2012 R2 Hyper-V Cluster and manage it with VMM 2012 R2. I just upgraded the cluster from 2012 RTM to 2012 R2 last week which meant pulling 2 nodes out of the existing cluster, creating the new R2 cluster, running the copy
cluster roles wizard since the VHDs are stored on CSVs, and then added the other 2 nodes after installing R2 on them, back into the cluster. After upgrading the cluster I am unable to migrate some VMs from one node to another. When trying to do
a live migration, I get the following notifications under the Rating Explanation tab:
Warning: There currently are not network adapters with network optimization available on host Node7.
Error: Configuration issues related to the virtual machine VM1 prevent deployment and must be resolved before deployment can continue.
I get this error for 3 out of the 4 nodes in the cluster. I do not get this error for Node10 and I can live migrate to that node in VMM. It has a green check for Network optimization. The others do not. These errors only affect
VMM. In the Failover Cluster Manager, I can live migrate any VM to any node in the cluster without any issues. In the old 2012 RTM cluster I used to get the warning but I could still migrate the VMs anywhere I wanted to. I've checked the network
adapter settings in VMM on VM1 and they are the same as VM2 which can migrate to any host in VMM. I then checked the network adapter settings of the VMs from the Failover Cluster Manager and VM1 under Hardware Acceleration has "Enable virtual machine
queue" and Enable IPsec task offloading" checked. I unchecked those 2 boxes refreshed the VMs, refreshed the cluster, rebooted the VM and refreshed again but I still could not live migrate VM1. Why is this an issue now but it wasn't before
running on the new cluster? How do I resolve the issue? VMM is useless if I can't migrate all my VMs with it.

I checked the settings on the physical nics on each node and here is what I found:
Node7: Virtual machine queue is not listed (Cannot live migrate problem VM's to this node in VMM)
Node8: Virtual machine queue is not listed (Cannot live migrate problem VM's to this node in VMM)
Node9: Virtual machine queue is listed and enabled (Cannot live migrate problem VM's to this node in VMM)Node10: Virtual machine queue is listed and enabled (Live Migration works on all VMs in VMM)
From Hyper-V or the Failover Cluster manager I can see in the network adapter settings of the VMs under Hardware Acceleration that these two settings are checked "Enable virtual machine queue" and Enable IPsec task offloading". I unchecked those
2 boxes, refreshed the VMs, refreshed the cluster, rebooted the VM and refreshed again but I still cannot live migrate the problem VMs.
It seems to me that if I could adjust those VM settings from VMM that it might fix the problem. Why isn't that an option to do so in VMM?
Do I have to rebuild the VMM server with a new DB and then before adding the Hyper-V cluster uncheck those two settings on the VM's from Hyper-V manager? That would be a lot of unnecessary work but I don't know what else to do at this point.
