Gluster users - Sep 2009 - Nufa mounting problem

Hi ,
I have a probelm mounting a client on a server while using nufa
When i mount without nufa(on the server) its ok when adding the nufa part
i see (df -a)
df: `/mnt/cluster': Transport endpoint is not connected

My conf is :

volume posix
  type storage/posix
  option directory /data
end-volume

volume locks
  type features/locks
  subvolumes posix
end-volume

volume b1
  type performance/io-threads
  option thread-count 8
  subvolumes locks
end-volume

volume server
  type protocol/server
  option transport-type tcp
  option auth.addr.b1.allow *
  subvolumes b1
end-volume


volume storage1
  type protocol/client
  option transport-type tcp
  option remote-host 192.168.0.20
  option remote-subvolume b1
end-volume


volume cluster-nufa
 type cluster/nufa
 option lookup-unhashed yes
 option local-volume-name `hostname`
 subvolumes storage1
end-volume

volume writebehind
  type performance/write-behind
  option window-size 5MB
  subvolumes cluster-nufa
end-volume


volume cache
  type performance/io-cache
  option cache-size 512MB
  subvolumes writebehind
end-volume

Anyone has any idea ?
