Allow resize of attached VHD-disks
Right now you cannot resize your VHD-disks once attached to a VM directly from the portal. Edit should be possible to at least increase the size of VHD-disks on demand.

Currently you can increase the size of a disk when the VM is in the stop-deallocated state. We are also working on a solution where a disk can be increased in size while attached to a running VM.

So...when can we expect this resize disks in a tuning VM?

As previously noted, Microsoft charges for the provisioned space of a managed disk. We cannot grossly oversize disks because of the cost. We need the ability to resize managed disks without deprovisioning the VM.

This post suggests charges are based on disk provisioned, https://azure.microsoft.com/en-us/pricing/details/managed-disks/ , not used. It's time to make resizing disk possible.

For older VMs which started out with 127Gb disks, this is an issue.

This creates a problem when trying to retrieve a VHD back to on-prem - the fully-populated VHD size may exceed the disk space of the on-prem machine, even though the used data of the VHD is small.

This is great if you are setting up a new server or have the ability to just rebuild a server(s) but what about exiting servers that need to be increased?

So, say that my C: drive is already at 127GB, but I really need to increase it. What are my options?

Does this work under Linux (Ubuntu, ext4 filesystem), i.e. can I safely allocate very large disk and assume that I will be billed for used space only?
