Oracle Linux (UEK kernel) is still support GFS or not?

 I would like to ensure my information, I tested Linux Clustering for httpd service on Oracle Linux. http://surachartopun.com/2012/07/learn-little-bit-of-rhel-cluster-on-ol.html

I found >>  FATAL: Module lock_dlm not found.

When I tried to recheck.
