I have a Windows Server 2008 instance on EC2. I need to shrink one of the drives (non-root) to a certain amount. Is there are well defined way of doing it?
There is a tutorial for Linux boxes described here, but while it may not apply directly, the concept is the same.
You'll need to:
So in essence, you're not resizing anything--you're creating a new EBS volume and transferring the content over using Amazon's built in snapshot system.
