http://docs.aws.amazon.com/cli/latest/reference/ec2/describe-volumes.html EBS volume has 2 states, The status of the volume (creating | available | in-use | deleting | deleted | error). The attachment state (attaching | attached | detaching | detached). The attachment state would be returned when volume status is in-use. Q: when will the attachment state be detached? After detached, volume status should be available.

Server defines the volume and device related operations for one host such as EC2

type VolumeInfo 

type VolumeInfo struct {
	VolID string

}

VolumeInfo records the volume's information.
