I work for an IT company that just recently signed a client that uses a clustered Hyper-V environment running on Windows Server 2008r2, and uses Shared Cluster Storage or Shared Volume.  The setup seems very strange to me.  They are configured in a fail over cluster, and both Hosts have their own servers running on them.  They both store their VMs at C:\ClusterStorage\Volume1, which is really an iSCSI connection to a SAN. 

On Host1 you can see the 7TB drive in Disk Management and it shows as online, but there are no drive letters or folder path assigned to it.  In Failover Cluster Manager, you can see that Host1 is the owner.  Host1 also holds the Quorum drive (I do believe it was on Host2 before)

On Host2 you can see the 7TB drive in Disk Management but it shows as offline, and of course no drive letter or path assigned to it. 

Both hosts use this volume, and somehow it is mapped to C:\ClusterStorage\Volume1.  Is this how a normal Hyper-V storage cluster looks and works?  We are able to move servers from one host to the other no problem, and creating a file or folder on one C drive shows up on the other.  Both Hosts have been up for over 390 days, and im wondering if something was changed and removed and when we reboot the hosts if they are going to lose their mapping to the shared volume, or is this is really configured somewhere else like in either Hyper-V manager or Failover cluster manager that I am just not seeing

Thanks

Hello,

We have a physical server running Windows 2012 Server Standard with the Hyper-V role enabled. One of the guest systems is a Windows 2012 Server Domain Controller. We are getting the following error message in the System Event Log:

Event ID: 32 - Source: disk - Description: The driver detected that the device \Device\Harddisk0\DR0 has its write cache enabled. Data corruption may occur.

In addition to this, there is the following event in the Directory Services Event Log:

Event ID: 1539 - Source: ActiveDirectory_DomainService - Description: Active Directory Domain Services could not disable the software-based disk write cache on the following hard disk.

Hard disk:

c:

Data might be lost during system failures.

I checked the properties of the logical disks on the host server, and the setting 'Enable write caching on the device' isnot selected on both logical drives.

The update KB2855336 is installed on the host server.

The guest server is using a virtual IDE controller for the hard drive, and the virtual hard disk is VHDX.

When I check the properties of the disk drive within the gues OS (virtual HD ATA device), the setting 'Enable write caching on the device' is selected, and there is a warning that says: "This device does not allow its write-caching setting to be changed."

I have yet to find a clear answer through the forums on if the above log entries can be disregarded, or if there is still additional work that needs to be done to ensure we do not lose AD if the host server crashes.

I am moving my customer from physical DCs to all Windows Server 2012 virtual DCs, and I need to know if I need to have a physical server running as their DC with the FSMO roles.

Any help would be appreciated.

   I have a new Windows 2012 R2 Hyper-V Server host running 6 VM's.  The host-based wbadmin (Windows Backup) seems to be running fine for all VM's except one.  Backing up the server produces the following results for this VM running Windows 2008 R2:

• Host wbadmin log: Detailed error: ERROR - A Volume Shadow Copy Service operation error has occurred: (0x800423f4)  The writer experienced a non-transient error.  If the backup process is retried, the error is likely to reoccur.
• VM System Event Viewer: Event ID: 1, VDS Basic Provider, Unexpected failure.  Error code: 490@01010004 (and also D@01010004)
• VM System Event Viewer: Event ID 58, partmgr.  The disk signature of disk x is equal to the disk signature of disk x.
• VM: After a failed backup I see console messages about drives needing formatted.  This is, from what I understand, part of the Hyper-V VSS backup trying to create VSS volumes on the VM.

   I've tried:

• Rebooting the VM.
• Running the backup from different Hyper-V hosts (shared-nothing live migrations to move the VM).
• Making sure that Integration Services on VM are up-to-date.

   The "problem" VM is running Active Directory, DHCP, DNS, Symantec Endpoint Manager, and Symantec Endpoint client.  Before the backup occurs all VSS Writers are "Stable" with "No error".

   Can anyone help me by pointing me in the right direction to try?  I'd certainly appreciate it!

Thanks!

Hope someone has an easy answer to this...!

I have a Windows 2008 SP2 server (physical) that houses a critical SQL database and Apache Server. What I want to do is have another server at a DR site with Server 2012 r2 preferably and have a Virtual machine setup that will replicate the Windows 2008 server. I want to do this without changing anything on the physical server now.

I have looked at Double Take availability but the target DR server has to be 2008 sp2 as well. I just want the simplest way to do this where if the 2008 source goes down they can continue working at the DR site if need be. What do you suggest? 

I have got +50.000 warning messages in EventViewer:System, since 26th December 2013. And I'm getting more warnings coming approximately every second.

Hi - I have this relatively old 2008R2 file server (8GB memory and 25TB disk) I'd like to use as file storage for a SQL Server VM.  The network is a 1GB switched configuration.  The VM resides on relatively new hardware (Server 2012, SAS) but doesn't have a lot of disk.  I'd like to make a bunch of the file server space available for SQL Server Data (2008R2) - its a small network (10 users) that we want to load a bunch of glob data indexed by a few keywords as reference.  Kind of like a GIS database.  My first thought is to create fixed vhdx file on the file server via Hyper-V manager, but this takes days to initialize for the size I'm thinking of (10TB).  I created an expanding disk and it was pretty quick to create.  I copied a 4GB file over the net to the mounted (from the Hyper-V Host) vhdx file and it went pretty fast.  I thought about using the iSCSI trick to attach it to the SQL VM (turning the file server into a SAN sort of?), but I'm wondering if this is overkill.  I'm just looking for a few suggestions.  There is a lot of stuff out there, some of it conflicting, about storage configuration.

Thanks

Hi,

I configured hyper-V in windows server-2012. I have configured Xampp server in that Hyper-V machine. The IP address of the Hyper-V machine is 192.168.50.68.

Iam unable to access that Xampp server from other system with the IP address. And iam unable to ping to that Hyper-V server from other machines in the network. When i try to ping to that IP, it it saying as destination host unreachable.

Hi there,

Would anyone be able to please advise as to how I can change the subnet mask for a Windows Server 2012R2 Cluster.

There are two windows server 2012R2 hosts with failove clustering and the hyper-v role installed. 

Each host has teams of 2X1GB nics for Management (cluster comms allowed), Live Migration, Cluster (Dedicated), VM Network.

Host1: Management: 192.168.1.1/24, Cluster : 192.168.4.1, Live Migration: 192.168.5.1.

Host2: Management: 192.168.1.2/24, Cluster : 192.168.4.2, Live Migration: 192.168.5.2.

The subnet mask only needs to be changed on the Management Nic team. It needs to have a subnet mask of 255.255.254.0 as the network has changed to 192.168.0.0/23 to allow for more IPs. The DNS (192.168.1.11) and default gateway(192.168.1.254) remain the same. The new host IP on host 1 would therefore be 192.168.1.1/ 255.255.254.0 and on host 2 it would be 192.168.1.2/ 255.255.254.0.

Thanks,

I am running a Windows 2008 R2 server with two NICs. I have one NIC configured with a static IP address, and the other configured with a dynamic IP address. The way my ISP is set up, static addresses and dynamic addresses are on completely different subnets.  I have a virtual adapter set up on the card with the dynamic address.  I am now trying to set up a 2012 server in a VM. I have it networking through the adapter with the dynamic address.  It works perfectly as long as it, too, has a dynamic IP address.  However, I'd like to give the VM a static IP address.  As soon as I do that, it can't talk to the gateway.  So, I have two questions:

1. Does the VM's address have to be in the same subnet as the NIC it's going through?
2. Is there some way I can make this work?  If so, how?

Thanks!

Brad.

Hello,

I'm trying to find out if I can use a single SMB share with multiple Hyper-V Clusters. Looking at:

How to Assign SMB 3.0 File Shares to Hyper-V Hosts and Clusters in VMM

I think it's possible. Since the File Server is going to handle the file locking it shouldn't be a problem.

Has anyone tried that?

Thank you in advance!

Hi.

I am currently investigating the possibility to run a remote desktop gateway on an virtual machine, and connecting to it (udp) threw the wmbus instead of a network adapter. It such a thing possible? Basically what I am asking is if I get use the VMBUS to connect to machine as i would a network adapter (on a specific upd port).

I ran across a post enabling debugging threw the VMBUS (I think): http://withinrafael.com/how-to-set-up-synthetic-kernel-debugging-for-hyper-v-virtual-machines/ if this is any way related to my question.

Cheers

Hello everyone!

I have two hardware servers, one is 2008R2 Hyper-V host and another one is 2012R2 Hyper-V host.

I need to move virtualized DC (2008R2 Server, FSMO roles) from 2008R2 host to 2012R2 Hyper-V host.  As far as i know export/import is not correct way to do such move of DC between Hyper-V hosts.

There are couple of other different opinions on forums about it, like shutdown the VM, copy .vhd file and recreate VM, etc, etc...

Which way to do it is valid?

Thanks in advance and sorry from my ugly english (not my native language).

Hi all,

we are currently implementing a backup solution to back up our HyperV2012R2 Failover Cluster VM's. The VM's have their disks on a 2012 R2 StorageSpaces Server shared via SMB3. The 'file server vss agent' service is installed on the storage system.

The HyperV host has several nics.

-One 1Gbit nic for management. The Host is registered in AD with this nic and the DNS entry points to his DNS name 'server.domain.local'

- One 10Gbit nic for the SMB Storage traffic in another subnet. The storage machine has a second Name who points to the ip of the 10G nic 'storage.domain.local'

- Other nics for cluster communication and VM traffic

The VMs are configured with the 10G name of the storage server and everything works well with hyperv.

Everytime i try to back up a machine (via the Software or with the Shell on an Hyper-V Host via DISKSHADOW) there is the following error message:

--------

DISKSHADOW> add volume \\storage.domain.local\vms01\server01

The provider does not support volume shadow copies for this volume in this context.
You must either change the context or add a different volume.
Note that changing the context might cause existing volumes in the shadow copy set to become unsupported.

--------

When i use his AD DNS name it works:

--------

DISKSHADOW> add volume \\server.domain.local\vms01\server01

DISKSHADOW> create

....

--------

Am i missing something? Has anybody an idea what the problem could be? Do I have to register the second name or nic in the storage server system or in the VSS providers?

Thank you for any help!

Hey guys

In my small/medium sized company we will soon update to Windows Server 2012 R2. I would like to implement virtual servers using Hyper-V. I didn't find a lot of information about Hyper-V in combination with storages spaces and autoamted storage tiers.
And this is very confusing to me as it seems to me that this would be the best practice as it is the most cost-efficient and most elegant solution.

My ideal scenario:

With Hyper-V I virtualize two Windows Server 2012 R2 instances. So two separate virtual machines.

I use the following disk setup:

1x cheap HDD  40GB for hyper-v server 2012 r2 core.

2x SSD 200GB (enterprise-grade)

2x HDD 4TB (7.2k, enterprise-grade)

Step 1:
I will install Hyper-V Server 2012 R2 Core on the 40GB HDD. Via command line, I will create a storage pool with automated tiered storage using the SSDs and the HDDs in mirrored mode the following way:

With Tiered Storage, I create a storage pool containing the SSDs and the HDDs. Then I create storage space A (1TB) and B (3.2TB) with the SSDs in a mirrored setup and the HDDs in a mirrored setup. The SSDs for the „hot files“ and the HDDs for the „cold files“.



Step2:

Ontop of the storage space A I want to install the first Windows Server 2012 R2 instance with Active directory. On storage space B I want to install the second Windows Server 2012 R2 instance for a business application to run on it.

Conclusion:

The SSDs are mirrored and therefore one SSD can fail.

The 4TB HDDs are mirrored and therefore one HDD can fail.

I have a fast and easy scalable environment.



But in the Internet I found many information that it’s not possible to install an operating system onto a storage tier.



Question 1:

Is this setup possible?

Question 2:

If this setup is possible, why is not everyone doing it?

Question 3:

Is it possible to do Step 1 over a GUI from a remote machine?

Question 4:

If the creation of Storage Tiers in the Hyper-V Server 2012 R2 is not possible. Would it work to use a Windows Server 2012 R2 as a parent system on the 40GB HDD? To do Step 1?

I would gladly get some feedback of people knowing Storage Tiers well.

Thanks a lot!

Is it possible to find through WMI on which virtual host a specific virtual machine runs? I am aware that there is a PowerShell solution. I am specifically interested in a WMI Query.

TIA

Hello,

One of our customer's Hyper-V host is having trouble.

The host have 320GB memory..

The host have 12 Virtual machine that is running now but there total memory is 62GB ..

However The host's memory is 291/320GB(91%) performance now.

The host have no application and etc, there are only installed Hyper-V role.

What should I check first? Please help.
