In this article, I will show you how to encrypt existing EBS volume using AWS web portal or PowerShell.
- Go to https://console.aws.amazon.com/ec2 and navigate to instances
- Once we have a volume created, go back to EC2 instances section and locate your instance
- Write down current Device name attachement info, for Linux instances, it is usually /dev/xvda
- Click on the currently attached volume, so you will be sent to the volumes section again, but filtered out to show you only one volume, so you will not misclick and disconnect a volume from another instance
That`s it, later you can remove unencrypted volume and snapshot
