Nope - indeed I have no idea what afra or unity are (and googling for
"gluster afra unity" doesn't match anything useful)

I have used the CLI utils as per the documentation, and everything "just
works".  There are a three files in /etc/glusterfs/ but they have not
changed:

$ ls -l /etc/glusterfs/
total 12
-rw-r--r-- 1 root root  229 2011-11-18 07:00 glusterd.vol
-rw-r--r-- 1 root root 1908 2011-11-18 07:00 glusterfsd.vol.sample
-rw-r--r-- 1 root root 2005 2011-11-18 07:00 glusterfs.vol.sample

All the config changes are instead reflected under /etc/glusterd/

$ ls /etc/glusterd/
geo-replication  glusterd.info  nfs  peers  vols

I see there's lots of *old* documentation for gluster <=2.x which talks
about doing things manually, but the new documentation has been seriously
dumbed down and doesn't even mention the module stacking configuration
files.

Attaching strace to the gluster processes might give you an idea what's
happening?
