Howdy, With 3.1.3 the option was added to disable the builtin Gluster NFS. Does that mean that the following scenario should work: 1. Disable Gluster NFS "gluster volume set <VOLUME> nfs.disable on" 2. Restart the gluster servers for good measure 3. On one of the gluster servers, mount the volume using the gluster fuse client: mkdir /export/users # In /etc/fstab add localhost:/users /export/users glusterfs defaults,_netdev 0 0 mount /export/users 4. Export the gluster mounted volume from the gluster server using CentOS 5.5 provided NFS server: cat /etc/exports /exports/users/someuser 192.168.2.10(rw,async,root_squash) 5. Start system provided NFS server on the gluster server, configure the firewall properly for NFS access 6. On the client machine, 192.168.2.10, check that the export is advertised: $ /usr/sbin/showmount -e nas-srv-01 Export list for nas-srv-01: /export/users/someuser 192.168.2.10 7. Mount it on the client 192.168.2.10 machine mount -t nfs nas-srv-01:/export/users/someuser /mnt/someuser mount: nas-srv-01:/export/users/someuser failed, reason given by server: Permission denied The server reports: Mar 30 11:59:50 nas-srv-01 mountd[20233]: authenticated mount request from 192.168.2.10:909 for /export/users/someuser (/export/users/someuser) Mar 30 11:59:50 nas-srv-01 mountd[20233]: Cannot export /export/users/someuser, possibly unsupported filesystem or fsid= required ================================= Mike Hanby mhanby at uab.edu UAB School of Engineering Information Systems Specialist II IT HPCS / Research Computing
