I this article I will show you how you can remove or de-attach EBS volume using Amazon web console.
Remove/De-attach EBS Volumes
First you have to unmount the attached volume from EC2 instance before de-attaching the EBS volume. If EC2 instance is running follow the below command to unmount the volume:
# umount <Device/remote Filesystem>
Now Go to Action -> click on ” Detach Volume” like below screen-shot.
After clicking on “De-attach Volume” it will ask for the confirmation. Than click on the “Yes,Detach“.
After de-attach the volume you can see the state has been changed to “available“.
