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.
You can detach or delete a volume on either the Droplet-specific menu or on the account-level Volumes page, in the volume’s More menu:
If you select Detach, you can then attach the volume to a different Droplet as needed.
If you select Delete, you’ll be prompted to confirm the deletion.
When you delete a volume, the volume and its contents will be completely deleted. This action is irreversible.
Click Confirm to delete the volume.
