Azure-docs: Unable to execute the commands successfully

[gyne]

Hi, I have been trying to follow the steps to enable me to upload a Microsoft VHD Image to azure and use it to create a VM however, I have not been able to.

So

1. $vhdSizeBytes = (Get-Item "<fullFilePathHere>").length - (this worked)

1. $diskconfig = New-AzDiskConfig -SkuName 'Standard_LRS' -OsType 'Windows' -UploadSizeInBytes $vhdSizeBytes -Location 'West US' -CreateOption 'Upload' (This also worked)

2. New-AzDisk -ResourceGroupName 'myResourceGroup' -DiskName 'myDiskName' -Disk $diskconfig - (This did not work).
   I get the error:

New-AzDisk : The upload size in bytes 112074530816 - 512 bytes for the VHD footer (112074530304 in this case) must be
a multiple of MiB.

When I run the below command to resize the Vhd to a multiple of 1024MB and a size of 127GB (136365211648 in bytes)
Resize-VHD -Path C:UsersPublicDocumentsHyper-VVirtual hard disksFinandOpsV10.vhd -SizeBytes 136365211648

I get the error below

Resize-VHD : Failed to resize the virtual disk.
The system failed to resize 'C:UsersPublicDocumentsHyper-VVirtualHardDisksFinandOpsV10.vhd'.
The requested operation cannot be performed as resize operation to new size that is smaller than or equal to the

@gyne Thanks for the feedback! We are currently investigating and will get back on this.

Thanks @VikasPullagura-MSFT
Just an update. I noticed that when I run this command
_get-vm "D365" | select -expand HardDrives | get-vhd_

as shown in the image, I get a different file size which is exactly a multiple of 1024 but when I run another command as shown in the image
_(Get-Item "C:\Users\Public\Documents\Hyper-V\Virtual hard disks\FinandOps10.0.5.vhd").length_
I get a different size which is not a multiple of 1024

NB: the FinandOps10.0.5.vhd is the vhd disk attached to the D365 VM in the first command

Thank you for your question! Since this channel is for driving improvements towards MS Docs, and your issue need deep investigation and live troubleshooting.
I would request you to open a support ticket so that this issue can be handled by a support engineer.

I came across this issue with the VHD for 365FO as well. The thing is that MS provides this VHD with Dynamic Type and Azure requires FixSize'd VHD. You can convert the type using Hyper-V Manager or Powershell

https://docs.microsoft.com/en-us/azure/virtual-machines/windows/prepare-for-upload-vhd-image

The values in the column below is what you should set your sizeBytes parameter to !AFTER Converting the VHD from Dynamic to Fixed

GiB Byte (Valid Values in Azure Multiples of GiB)

128 = 137438953472

256 = 274877906944

512 = 549755813888

1024 = 1099511627776

2048 = 2199023255552

4096 = 4398046511104

Firs install Hyper-V role on the Windows 10 or the Windows Server on-premise (this is the full feature name which will include Microsoft-Hyper-V-Management-PowerShell)

DISM /Online /Enable-Feature /All /FeatureName:Microsoft-Hyper-V

Convert your VHD to Fixed size instead of Dynamic (you must do this) and also convert from VHDX to VHD

Convert-VHD -Path filepathtoyourDynamicVHDorVHDX.VHDX file -DestinationPath destinationfileofnewVHD.VHD -VHDType Fixed

Verify the Size of your FIXED SIZE VHD BEFORE RESIZING (not file size) the filesize will always be equal to Size + 512 Bytes (automatically you do not need to add 512 Bytes)

Get-VHD -Path 'PathtoYourFixedSized.VHD' | Select-Object *

Now the magical Resize Command which requires Hyper-V to be installed

Resize-VHD -Path 'PathtoYourFixedSized.VHD' -SizeBytes '274877906944' #for a 256 GiB Disk

Verify the Size BEFORE RESIZING (not file size) the filesize will always be equal to Size + 512 Bytes (automatically you do not need to add 512 Bytes)

Get-VHD -Path 'PathtoYourFixedSized.VHD' | Select-Object *
