If you have the GFS source, look at cluster/doc/min-gfs.txt You can also look at this file online through the web interface to CVS at http://sources.redhat.com/cluster/. This has a description of how you should set up a 2 node cluster, using a third node as a GNBD server. The hangs could also be a problem with the init scripts. > 3.
