Description:
Is it possible to specify the size of the OS disk upon VM creation?
This question was recently asked here: https://github.com/Azure/azure-xplat-cli/issues/2601. @amarzavery responded, but named only the command for specifying the size of a data disk upon VM creation.
The default OS disk size is 30GB, and this is very large for the VM we are using. It doesn't seem that there is anyway to use vm set --new-os-disk-size to shrink the OS disk, so is it possible to set the OS disk size to smaller than 30GB upon creation?
The VM size we're using is Standard_DS3_v2, but that doesn't seem to matter.
EDIT: The size of the OS disk matters in particular because we are creating VHDs from the VMs, and these are now also 30GB in size.
I was using Google Cloud but it was so difficult to download a VM I couldn't figure out how to do it. So I got on MS Azure and figured it out in about 10 min. I was overjoyed and then.... It's a gut busting 30 gb ! My VM's are only about 5gb max. I was almost there.... I have a fast network but 30gb was going to take about 5-6 hrs.
@jatt77 If you have access to PowerShell, try the Save-AzureRmVhd cmdlet and see if it takes the same time for download. The equivalent cmdlet for upload Add-AzureRmVhd only uploads the actual data and not the 0s. I'm not sure if Save-AzureRmVhd has the same behavior but it's worth a try.
great ok I will try it.
Thank you so much.
