To remove a volume from a Droplet, you can either delete or detach the volume.
Before doing either of these actions, unmount the volume to make sure it’s not in use to avoid operating system errors.
To detach an attached volume, visit the Volumes section of the Droplet’s detail page. You can get to a Droplet’s detail page by clicking the Droplet’s name in the main interface:
Click on the Volumes item in the side menu:
You will be taken to an area where you can see the volumes currently attached to the Droplet:
In the More menu of the volume you wish to detach, select the Detach option:
You can now attach the volume to a different Droplet as needed.
When you delete a volume, the volume and its contents will be completely deleted. This action is irreversible.
To delete a volume, locate it on the account-level Volumes page or the Volumes page for an individual Droplet. Open the volume’s More menu, and click Delete.
