Help - The chain of virtual hard disks is corrupted
I took a snapshot of a VHD that I tried to expand to 40GB. After expanding I tried to restart the VM but got the error that "The Chain of virtual hard disks is corrupted".
Apparently because I expanded the Parent VHD it threw up this error ( i assume because the snapshot differed in size?)
This led me to Vhdtool which I ran: vhdtool.exe /repair parentvhdfile.vhd snapshotvhdfile.vhd /quiet
This appeared to have run okay. However when I went to restart the VM again I got the error:
Servername Failed to start
Microsoft emulated IDE controller failed to power on with error - the chain of virtual hard disks is corrupted. There is a mismatch in the virtual sizes of the parent virtual hard disk and differencing disk.
Failed to open virtual disks. The size of the vurtua;l disk is not valid.
etc...
I notice that my parent VHD = 40GB in size, whilst the Snapshot (avhd) file = 109K
I think I need your help, I don't know what to do!!
If you made changes to the parent drive, your chain will be corrupted. Changes to the parent disk invalidate all the child disk.
Do you have a backup of the original parent disk?

SCVMM and "Virtual Hard disks" directory
Hello,
We have noticed that Virtual Machines created using SCVMM doesn't create "Virtual Hard Disks" directory and puts the VHDX files into the Virtual Machine data root.
But if VM are created using Hyper-V defaults values this directory is created.
How can we set/define SCVMM to use also this directory?
We would like to have the same directory structure when VM are created, and the usage of "Virtual Hard disks" directory is quite clean directory sctructure.
Best Regards.To add - the feedback from the majority of folks is that they expect / prefer the way that SCVMM does this and wish that Hyper-V would do it this way by default. (each VM neatly in its own folder and not spread across the Hyper-V Server file system
is what most folks prefer.)
As Samir mentioned, only performing disk move actions in SCVMM or using PowerShell to drive the SCVMM deployment (and defining more granular settings) would change this default action.

Creating a Master virtual hard disk and using the same for all other VM's
Hi,
We would like to create a master virtual hard disk and use the same for all other VM's. Can we do that ?
my requirements :
1) create 10 VM's
2) first create a master virtual hard disk with win OS and use the same to create the 10 VM's.
3) After creating the VM's change the HDD size.
-- if i have created master virtual disk with 500GB , and use the same for creating a virtual machine. can we change the HDD size to 1TB ?
After creating the VM's ,i will change the system names and activate the windows accordingly.
Will there be any implications ,if we can/will do like this.
Thanks.Hi Suren424,
I think Using Differencing Disks may cover your needs .
Please refer to following setps:
"Create the Parent Virtual Machine Configuration and Virtual Hard Disk
Install the Operating System, updates, and common software
Generalize the installation
Prepare the parent virtual hard disk
Create the differencing disks
Create virtual machines that use the differencing disks
For details please refer to follwing link:

Error (23317)
The operation Change properties of virtual machine is not permitted on a virtual machine that has shared virtual hard disks.
Recommended Action
The operation Change properties of virtual machine is not permitted on a virtual machine that has shared virtual hard disks.
Is this limitation by design? If we have a shared VHDX between two VMs, then I am not able to change the VM properties from SCVMM.
SCVMM 2012 R2 with Windows Server 2012 R2 Hyper-V.
Appreciate any help !
Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence.
InsideVirtualization.comHello,
that is a VMM issue.
If you did not deploy your virtual cluster from a VMM service template, VMM doesn't recognize the configuration.
Until MS got it fixed, you could use the workaround from system center central:

The storage where the virtual hard disk is located does not support virtual disk sharing
Hi everyone,
I deployed 2 hyper v vitual machines a while ago, and i did that because I needed to test my current game Project, which is an
online game. However, i've had some problems with my Windows installation then I had to reset the pc by making it a refresh
install. I still have the hyper v virtual disks, but i cannot attach it to a new hyper-v virtual machine. it pops up this message:
"the storage
where the virtual hard disk is located does not support virtual disk sharing". I dont know anything about virtual machines, so I
didnt know I had to make the disk sharable. How can I force to attach the hard disk to a new hyper-v? I dont want to go t
hrough the whole proccess of installing the operating system all over again and updating it....
Any help is greatly appreciated!
Thanks in advance,
Romulo RomeroHi MrDebugging,
>>
When I Try to add a SCSI Controller, and then I click browse to add a UNC I get this:
C:\Users\Public\Documents\Hyper-V\Virtual hard disks\ClienMachine.vhdx
but I tried placing in different location, and the same problem occurs!
By the way, Im not on a server , I am a domestic user and I am running it on my
Windows 8.1
According to the error message , it seems that it is not a permission issue .
The VM is Gen 1 or Gen2 ?
Generally the error message occurs when you enable "shared vhdx" on standalone/client hyper-v host :
Please try to attach the VHDx file to IDE controller if it is a Gen 1 virtual machine (because only the SCSI controller has the option "virtual hard disk sharing" and Gen 1 VM only can boot from IDE )
All in all , please do not use this feature without CSV or Scale-Out File Server with SMB 3.0 on file-based storage .
If it is not the case , please detail steps what you did .

Resize the CentOS LVM inside VM from a secondary virtual hard disk
Requirement:
Airwave installed on a VM, with a secondary virtual hard disk.
we have a KB "Resizing the centOS LVM inside VM", is only useful if we have one hard disk for that VM instance.
https://arubanetworkskb.secure.force.com/pkb/articles/FAQ/Resizing-CentOS-LVM-inside-VM
However, This KB will be helpful in the scenario's where VM Administrators has to create a secondary virtual Hard disk, instead of increasing the disk space for current hard disk (could be for any reason for example: he cannot increase the disk space for the same disk as the pool that provides space to that disk has no space etc..).
Solution:
In this case, when we have added a secondary virtual hard disk, when we do # fdisk -l, we will see the secondary disk as /dev/sdb as shown below:
[root@localhost mercury]# fdisk -l
Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000650f3
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 102400 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 13 5222 41839616 8e Linux LVM
Disk /dev/sdb: 17.2 GB, 17179869184 bytes
255 heads, 63 sectors/track, 2088 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/mapper/VolGroup00-LogVol01: 4294 MB, 4294967296 bytes
255 heads, 63 sectors/track, 522 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/mapper/VolGroup00-LogVol00: 38.5 GB, 38520487936 bytes
255 heads, 63 sectors/track, 4683 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
And this is the # df -h, command output, before the LVM extension:
[root@localhost mercury]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
36G 11G 23G 32% /
tmpfs 3.7G 0 3.7G 0% /dev/shm
/dev/sda1 97M 37M 56M 40% /boot
We need to extend the sdb disk space to VG group to combine to use the disk space as shown below in the configuration:
Configuration:
1. First, we need to create a partition in /dev/sdb
[root@localhost mercury]# fdisk /dev/sdb
# n {new partition}
# p {primary partition}
# 1 {select partition number, by default 3 is the next available}
# use the default cylinder values for First and last
# t {select partition id we just made (1)}
# 8e {Linux LVM partition}
# p {print. the new device should be described as Linux LVM}
# w {write to memory}
2. We need pv reate /dev/sdb1:
[root@localhost mercury]# pvcreate /dev/sdb1
3. Execute the command to extend the VG to sdb1:
[root@localhost mercury]# vgextend VolGroup00 /dev/sdb1
4. Enter the command to extend the LV to sdb1:
[root@localhost mercury]# lvextend /dev/VolGroup00/LogVol00 /dev/sdb1
5. Resize the VG:
[root@localhost mercury]# resize2fs /dev/VolGroup00/LogVol00
Done.
Verification
Now look at the # df -h, output, which will be different:
[root@localhost mercury]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
52G 11G 38G 22% /
tmpfs 3.7G 0 3.7G 0% /dev/shm
/dev/sda1 97M 37M 56M 40% /bootHi Eric,
"My first thought was to do is reduce the drive, which I know cannot be done. I then thought to convert the disk but it consumes the whole of the dynamic potential, which somehow is a maximum of 2TB."
Yes , we can not get the disk space less than 2TB .
As a workaround , you can try the following steps :
1) defrag the volume in VM , after that shutdown the VM
2) use "edit disk" in hyper-v manager to compact the VHD file
3) start that VM then shrink the volume that the disk space is larger than the VM needs in disk manager
This may limits the expansion accordingly .
Hope it helps

Hello,
Issue:
On a Virtual Machine with a secondary VHDX attached, I cannot manage (bring online, initialize, partition, format, or write to) the VHDX hard drive once it has "Enable Virtual Hard Disk Sharing (VHD Sharing)" enabled.
Questions:
Should I be able to manage (bring online, initialize, partition, format, and write to) a VHDX hard drive once it has VHD Sharing enabled? If I should be able to manage it, what am I missing?
Topography:
One SuperMicro Cluster In a Box (CIB) with 2012 R2 Data Center on each node. Microsoft Failover Cluster installed and working on each node. The Failover Cluster Servers on each host passes all cluster validation tests. Two Hyper-V 2012 R2 Data Center Virtual
Machine (VM) servers, one on each node. 1 common Cluster Shared Volume (CSV) and 1 Generation 2 Scale-Out File Server (SOFS) shared volume both Resilient File System (REFS) formatted. One 5 Gigabit (Gb) Virtual Hard Drive Type X (VHDX) file on the CSV and/or
SOFS. Integrity bit and read only turned off on VHDX file.
Each of the two Hyper-V VMs have one 127Gb VHDX Generation 2 primary hard drive and 1 VHDX secondary hard drive attached, both on SCSI Controller #1.
Background:
If I start VM1 without the VHD Sharing enabled on the secondary hard drive, I can bring the drive online, initialize, partition, format, and write to the drive.
If I enable VHD Sharing, I can no longer modify the drive in Disk Management in any way. With or without VM2 running.
Both VMs and the CSV and SOFS are on the same host cluster server, or not, no difference…
The VHDX is referenced either by the CSV name C:\ClusterStorage\Volume1\TEST1.VHDX
or a Shared Folder name
\\sharedfolder\folder\Test1.VHDX .
If I start VM1 with VHD Sharing disabled and I format the drive, then shut down and enable VHD Sharing, the drive is offline and requests initialization which fails with an "I/O device error", every other attempt to manage the drive fails with
the same "I/O device error", error.

Thanks again for any help,
RobertHi All,
I had to buy a Willy Wonka bar and spend a golden ticket to get an answer to this one.
We found that the default LogicalSectorSizeBytes of a VHDX is 512b. It needs to be 4kb.
The Host drive doesn't seem to matter CSV or SOFS. Below is a way to create a VHDX with the correct LogicalSectorSizeBytes.
In Power Shell, type --> New-VHD -Path C:\ClusterStorage\Volume4\Cluster2DataDisks\Cluster2Disk1.vhdx -SizeBytes 200Gb -PhysicalSectorSizeBytes 4kb -LogicalSectorSizeBytes 4kb
Attach the resulting file to your guest cluster servers and set the Enable Virtual Hard Disk Sharing option on both server. You should now be able to bring the drives on-line and initialize them. They will also add to the guest cluster pool.
Change the size, path and file name above to fit your Cluster Servers configuration.
Thank You
Sachin Kumar Support Engineer | Windows Server Setup Team | Microsoft Enterprise Platform for finding the answer to this one.
Hope this helps others.

New Virtual hard disk wizard hangs after creating new vhd from huper-v manager on windows 7
New Virtual hard disk wizard hangs after creating new vhd from huper-v manager on windows 7 workstation.
Windows 2008r2 hosts the hyper-v server. I can create VMs and VHD's when connecting to the server locally with the hyper-v manager.
The issue arises when I try to connect to the hyper-v server from my workstation which runs windows 7.
I have installed The Windows6.1-KB958830-x64-RefreshPkg.msu that was suggested for windows 7 sp1.
I can connect to the hyper-v server, create vm's but I cannot create vhd's the gui just hangs with no errors in event log or on screen.
The files are there on the hyper-v hard drive but i suspect they are just created by windows as they are written and are not valid.I've had just the same solution. Both did Hang Fixed size and flexible.
Two parts were taken:
1 - KB939820 for Windows 2003 server based domain controllers
2 - disable using IPv6 on your NIC
Result - both types of VHD's are created normaly.

Can you point me to the best way to do this? - Thanks
If you have the two allotted activations already and one was lost on the hard drive that failed then you need to contact Adobe Support thru chat and ask them to reset your activations.

i was add new hard disk in my VM and choose the parent is my old one but it overwrite on the basic Virtual Hard Disk and i lost all data i only have file .avhdx same size for the old Basic virtul hard disk .i need to back an recover my data can i use the
.avhdx file to recover my data? or how can i do that?
please urgent.
If you had an AVHDX, then you had a checkpoint / snapshot.
If this was the case, you should not edit the configuration directly, but instead mange checkpoints.
Simply attach to the correct AVHDX and you will see the data contained within the AVHDX.
