Error during Resize-Image when making windows 10 image

[icksa]

I'm trying to create a windows 10 openstack image. During the Resize-Image step, I am getting a "Not Enough Available Capacity" error. Do you have any suggestions about how to get around this?

Thanks

Hello, Could you give us some details about your workflow? Did you use the New-WindowsOnlineImage or New-WindowsCloudImage? How does your config file look like?

Hello,

You have hit a weird PowerShell issue for the Resize-Partition, as the minimum partition size does not coincide with the minimum resizeable partition size. As your image file has already been generated, you can unmount it manually and run "qemu-img.exe convert -O qcow2 image.vhdx image.qcow2". You will find qemu-img.exe in the bin folder.

To try to fix the code, you can increase the number of retries of the resize or increase the minimum buffer for the resize. https://github.com/cloudbase/windows-openstack-imaging-tools/blob/master/WinImageBuilder.psm1#L990 or https://github.com/cloudbase/windows-openstack-imaging-tools/blob/master/WinImageBuilder.psm1#L963

By default, the number of retries is 4.

Thank you for responding so quickly. I increased the retry count in WinImageBuilder.psm1 and was able to get around this issue.

Thanks again.

@icksa I will make a patch to increase the retry count to a higher value so that this issue does not happen anymore.

@icksa I added also a binary search resize retry as sometimes not even 20 or 30 retries are not enough on Windows 10 updated. https://github.com/cloudbase/windows-openstack-imaging-tools/pull/294
