kubernetes persistent volume accessmode
<p>It seems that Kubernetes supports 3 kinds of access mode for persistent volume: <code>ReadWriteOnce</code>, <code>ReadOnlyMany</code>, <code>ReadWriteMany</code>.
I'm really curious about the scheduler strategy for a pod which uses the <code>ReadWriteOnce</code> mode volume. For example, I created an RC which have pod num=2, I guess the two pods will be scheduled into the same host because they use the volume that has <code>ReadWriteOnce</code> mode? 
I really want to know the source code of this part.</p>
