+ * This test checks that various VolumeSources are working.
+ *
+ * There are two ways, how to test the volumes:
+ * 1) With containerized server (NFS, Ceph, Gluster, iSCSI, ...)
+ * The test creates a server pod, exporting simple 'index.html' file.
+ * Then it uses appropriate VolumeSource to import this file into a client pod
+ * and checks that the pod can see the file. It does so by importing the file
+ * into web server root and loadind the index.html from it.
+ *
+ * These tests work only when privileged containers are allowed, exporting
+ * various filesystems (NFS, GlusterFS, ...) usually needs some mounting or
+ * other privileged magic in the server pod.
+ *
+ * Note that the server containers are for testing purposes only and should not
+ * be used in production.
+ *
+ * 2) With server outside of Kubernetes (Cinder, ...)
+ * Appropriate server (e.g. OpenStack Cinder) must exist somewhere outside
+ * the tested Kubernetes cluster. The test itself creates a new volume,
+ * and checks, that Kubernetes can use it as a volume.
