What is the effect of detaching an EBS volume from an EC2 instance that is running?

Question

Gowtham Hari Dhandapani · Accepted Answer

If you try to detach the root EBS volume while the instance is running, you'll get an error. Amazon EC2 doesn't allow detaching the root volume from a running instance, as this would cause the instance to immediately stop functioning. Detaching non-root volumes can lead to data loss if not done properly and can prevent the instance from accessing data on that volume.
