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.
If you are using Server 2012R2 failover cluster please install the following update:

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.

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.

Exchange 2013 MBX in DAG along with Hyper-V and Failover Cluster

Hi Guys! I've tried to find out an answer of my question or some kind of solution, but with no luck that's why I am writing here. The case is as follows. I have two powerful server boxes and iSCSI storage and I have to design high availability
solution, which includes SCOM 2012, SC DPM 2012 and exchange 2013 (two CAS+HUB servers and two MBX servers).
Let me tell you how I plan to do that and you will correct me if proposed solution is wrong.
1. On both hosts - add Hyper-V role.
2. On both hosts - add failover clustering role.
3. Create 2 VMs through failover cluster manager, VMs will be stored on a iSCSI LUN, the first one VM for SCOM 2012 and the second one for SCDPM 2012. Both VMs will be added as failover resource.
4. Create 4 VMs - 2 for CAS+HUB role and 2 for MBX role, VMs will be stored on a iSCSI LUN as well.
5. Create a DAG within the two MBX servers.
In general, that's all. What I wonder is whether I can use failover clustering to acheive High Availability for 2 VMs and at the same time to create DAG between MBX-servers and NLB between CAS-servers?
Excuse me for this question, but I am not proficient in this matter.

Hi,
As far as I know, it’s supported to create DAG for mailbox server installed in hyper-v server.
And since load balance has been changed for CAS 2013, it is more worth with DNS round robin instead of NLB. However, you can use NLB in Exchange 2013.
For more information, you can refer to the following article:
http://technet.microsoft.com/en-us/library/jj898588(v=exchg.150).aspx
If you have any question, please feel free to let me know.

Windows Failover Cluster (Errors retrieving file shares)

I'm having an issue with Windows Failover Cluster with a Windows Server 2012 R2 machine. I have two cluster nodes (nodeA and nodeB). My issue is that when nodeA is the owner node, and I open failover cluster manager <clusterName> >>
roles >> <fileserver role> >> shares tab it will hang and say that it is loading, but this will occur infinitely. Although when I go to nodeB (not the owner node) and I go to shares it will show me all of the shares that I have. Next when
I go to <clusterName> >> Nodes >> click on Roles tab the information says "There were errors retrieving file shares."
Now when I switch the nobeB to the owner node, I cannot view the shares on that machine but can now view them on nodeA.
We alse have a test network where I have recreated the machines, environment and the failover cluster to as close as the production network as I can except everything works great in the test network

For anybody searching on this later...
I was getting "There were errors retrieving file shares" no matter which node of my cluster
owned the fileshare service. Turns out my problem was that my servers don't have internet access and I had set a system proxy. The fix described in the link below was to exclude the local domain from the proxy.

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.

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.

Event Logs of VMs Migration in Failover Cluster of Hyper-V Hosts

Hello All,
We're running Failover Cluster of Hyper-V hosts of Windows Server 2012 R2. Using SCVMM 2012 R2 with UR5 for management.
If any host gets down unexpectedly (due to any reason power/bugcheck/hardware failure or what so ever), then the VMs on that host, of course, get migrated (either quick or live) to some other host within the cluster.
I want to have logs/events of this VMs migration. I want to know that which of the VMs were residing on that host at that time of failure. Of course, we can't have this info in the Cluster events is Failover Cluster Manager. I am unable to find this info
anywhere. I have searched in Event Viewer --> Administrative Roles --> Hyper-V. I have searched a lot in the SCVMM, but no success.
Please help me in finding the exact location of these logs/events. I would also like to know that if the VM was quick migrated or live migrated, and to which host the VM got migrated.
I'd be highly grateful.
Thanks in anticipation.
Regards,
Hasan Bin Hasib

This post was cross-posted in the clustering forum. As noted in that forum, a failure of a host does not initiate a quick or live migration. Migration requires both the source and destination nodes be operational during the entire migration
process. Should a host fail, it is impossible for that host to participate in a migration. In the case of a host failure, the VM is restarted on another node of the cluster. You can still use the information provided by Elton for viewing
events in the event log. If you want to see the exact sequence of log entries, perform quick/live migrations in a lab and notices the changes in the event log. You can also fail a host and see the sequence of log entries.

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
Best Regards
Elton Ji

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

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:
http://support.microsoft.com/kb/281662
Run the DC in a virtual machine, and then put it on top of the cluster.
Thanks!

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.

Moving VMs from Standalone Hyper-V to Hyper-v Failover Cluster

Hello All.................I need to move Virtual Machines from Standalone Hyper-V based on Windows Server 2012 R2 to a Hyper-V Failover Cluster based on Windows Server 2012 R2.
- The VMs OS is Windows Server 2012 R2
- Applications installed on VMs are SCCM, SCOM, SharePoint, etc.
1. I am looking for a Checklist that I can run through and move them. To make sure I do not miss out anything.
2. Would a downtime be required in this scenario while the VM is being moved?
3. What requires special attention in this scenario?

Thanks for the reply.
So, I do not need to do anything and just simply add both the cluster and standalone into VMM and then simply use the Move option. Please, confirm if I have understood it correct.
Yes. But be carefull. First shut down your VM's
if possible and configure them in such a way they don't automatically start. If you install the SCVMM Agent, some Hyper-V related services are restarted, when some VMs start during that process you system may stall. I have seen this multipe times.
There is another dirty option that worked of us perfectly. Export the VMs. Then import those VMs to a local disk on one Hyper-V Server. Refresh the Hyper-V Server and Virtual Machines on that Hyper-V Server. Give it a few minutes. Then do
a Live Migration while at the same time makeing it "Highly Available" by moving it to your CSV. Works flawlessly. DO NOT IMPORT THE VMS TO YOUR CSV, otherwise you can't change it to "Highly Avaiable" unless you have
two CSVs. Importing it straight to a CSV does not make them Highly Available.

SCVMM created VMs not displayed in Failover Cluster Manager

I have a 2012 Hyper-V failover cluster setup and recently added SCVMM 2012 SP1 to the mix so I could perform some P2V migrations and familiarize myself with its other many capabilities. I noticed that if I create a VM inside SCVMM it doesn't show up in the
FCM UI with the other VMs I created from FCM. VMs that you create in FCM do get picked up by SCVMM however. Is this by design?
Thanks,
Greg

For my issue above, this was because I'd not noticed and thus not ticked the box on the Live Migrate wizard that says "Make this VM highly available".
I moved the VM out of the cluster, manually deleted the failed "SCVMM <VMName> Resource", then moved the VM back onto the cluster again but this time ticking the box to make the VM highly available. All looked fine in failover cluster manager.
I do rather wonder why SCVMM designers think I might want to migrate a VM onto a Hyper-V cluster and NOT want it to be highly available...? Likewise, to be able to move the VM back out again to a standalone host once it's correctly in the cluster, you have
to untick the "Make this VM highly available box". Surely this should just be done automatically in the background?

Create failover cluster to host Windows 2012 DC, Exchange 2013 and SQL as VMs

One of our clients has running Windows Essential 2012, SQL and exchange 2007 as VM on VMware for 4 years without major issue. However, the physical server is getting old and have some hardware issues recently. They have budgets to buy two Dell servers, EqualLogic
SAN, Windows server 2012 Datacenter and Exchange 2013. Is it possible for them to create failover cluster to host Windows 2012 DC, Exchange 2013 and SQL as VMs?
