Thanks for all the help... I finally managed to get this working correctly. All I needed to do was install the nfs-common package in both servers and clients and restart the glusterd daemon on the servers: $ sudo aptitude install nfs-common $ sudo service glusterd restart after this running "showmount -e" shows the correct result on all gluster nodes: $showmount -e <gluster-server-ipaddress> Export list for <server-ipaddress>: /datar2 * /www * /upload * Hope this saves some headaches and spares some keyboards for someone with the same problem. Also the glusterFS deb file for Ubuntu should list nfs-common as a dependency to avoid this problem in the first place. thanks again.....
