Click Remove (you are removing the pointer to the drive not the VHD file / you should have a backup anyway ).click the Hard drive (for the drive we are extending).Launch Hyper-V Manager on the HOST (of the 2003 machine).When you create the disk Hyper-V manager adds the security settings that are needed for the VHD. If that happens just come back and do this step. If you skip this step you will likely get a bunch of security error messages when you boot the VM and the boot will fail. We have to login to Hyper-V manager host of the 2003 server and Remove the disk.Double-click machine you used to extend the VHD.

#ADD MORE DISK SPACE TO HYPER V WINDOWS#

Shutdown the server so you can remove the disk (on Windows Server 2008 R2 Host you can hot remove storage without shutting down).

Now you need to detach it from the 2008 box and reattach to the 2003 box.

Click Finish on the summary screen and like magic your disk is extended.

It should default to the maximum allowed on the disk.

Just click Next on the information page.

This will kick off a very simple wizard.

Right-Click the partition of the disk that you need to extend (in my case it is Disk 0) G: Partition.

Make sure it is attached to IDE Controller вЂ“ click OK.

Browse to the disk you want to add and select it.

Double-click machine you will use to extend the VHD.

Make sure you attach it to an IDE controller (not SCSI) To do this:ДЄdd an additional disk to an existing Windows Server 2008 or 2008 R2 machine, use the VHD you want to expand. However, snapshots are a problem so you can only do this with a single VHD without any snapshots.Д¬AUTION: This is NOT supported so proceed at your own RISK.

The only way I could figure out how to pull this off (without third party tools) is to mount the VHD on a windows Server 2008 or later machine and just extend it there. You cannot extend the partition of an OS disk using diskpart so I am going to attach my boot disk to another server that has extend capabilities. To do this you would follow 325590 ( ) How to use Diskpart.exe to extend a data volume in Windows Server 2003, in Windows XP, and in Windows 2000. If it is not a boot volume you can use DiskPart. NOTE: Best practices for using dynamic disks on Windows Server 2003-based computers, DiskPart cannot be used in my case because this is a boot volume. I can Convert the Basic disk to Dynamic Disk but this would not solve my problem because you cannot extend the volume of an OS drive. Since this is a boot volume I am really limited on what I can do with it.

Part II вЂ“ Extending The Boot Volume To Use The Full Larger VHD Unallocated Capacity Notice you now have new unallocated space.Start => Right-Click My Computer => Select Manage.Start Server => Login as an administrator.You will see that you have successfully made the VHD capacity larger by adding unallocated space to the end of it. Now login to the server and open disk manager. for information on how to merge a chain see How To Merge a Chained Differential VHD Disk So It Can Be Extended and Expanded. Note: if you have a disk вЂњchainвЂќ you will need to merge the chain before this option is available.Note: if this is a dynamically expanding disk, it will not actually expand the disk, it only expands the capacity.In the size box put in the size you want to make the new drive.Turn on the checkbox to Expand virtual hard diskвЂќ.Click on the Hardware Configuration Tab.

Double-Click on the server you want to modify.

Here is what you would need to do with SCVMM. Since SCVMM uses PowerShell for everything, you can do this with PowerShell but I did not do the leg work to come up with the specific commands. The first part is pretty easy using System Center Virtual Machine Manager. In this example, I am actually going to use features built into Windows Server 2008 to extend the volume of my Windows Server 2003 Boot partition by simply attaching it to the server as a data disk, doing the work on it then reattaching it to the 2003 server. The second is expanding the boot partition to use all the new space. This easier way to increase capacity was documented at: How To Expand and Extend To Increase Capacity On A Virtual Hard Disk The Easy and Fast WayвЂ“Solve the problem of вЂњOut of Disk Space on Drive CвЂќ Forever. NoteвЂ¦ this is much, much easier with Server 2008 and higher I finished working on an easier way to do this that does not require SCVMM. I documented the process at: How To Expand and Extend To Increase Capacity On A Virtual Hard Disk The Easy and Fast WayвЂ“Solve the problem of вЂњOut of Disk Space on Drive CвЂќ Forever Revised to add merge change instructions link and link to simple way to do this using diskpart.
