We, the OpenGFS group (http://www.opengfs.org) are working on OpenGFS which is
a free fork of GFS.  Currently we are working on OpenGFS 0.1 which is GFS 4.1
minus the truckload of bugs Sistina has in it's code base.

After that OpenGFS will diverged more, but trying to stay ondisk and - if
possible - protocol compatible to GFS 4.x


Of course it doesn't work. We've performed a software upgrade.
