time (GCE PDs attached in RW mode, for example), then the volume must be
manually detached before Kubernetes can attach it to other nodes.
  * If a volume is already attached to a node any subsequent attempts to attach it
again (due to kubelet restart, for example) will fail. The volume must either
be manually detached first or the pods referencing it deleted (which would
trigger automatic volume detach).
