Azure VM O/S Disk Size ?

Question

Hello

I am deploying windows VM from the marketplace and the default size of the disk is 128GB.
Is it possible I can change this disk size to say 40GB? What are the steps ?

Answer 1

There is similar discussion in the GitHub : https://github.com/MicrosoftDocs/azure-docs/issues/40633

You cannot resize the OS down, only up. So this is not possible.

If you want a Windows Server with a 40GB OS disk, we actually have a specific images for that in the Azure Marketplace. They all have [small disks] in the title

I dont see any small disk option in the azure portal.
i think it is all gone?
What can be done if we want a VM with 0/s disk size less than 128GB ?

Answer 3

Please try with different VM sizes as well as regions as this could be a capacity/availability issue as described here.
