hallo Olivier, you should start the call with better overview. (client-ip client-os Server-ip server-os action result...) I hope to understand what you mean. 99.200 linux | 99.202 linux gfs-3.3.1 | mount -o vers=3 nfs://$server/vol1 /mnt | error="access denied" 98.66 sol11 | 99.202 linux gfs-3.3.1 | mount -o vers=3 nfs://$server/vol1 /mnt | not receive an access denied Do check running "one" nfsd on nfsserver only. [1] > nfs.rpc-auth-allow: 10.1.99.201 all clients should be added. i had to use the following command on solaris-client: nfsserver # gluster volume status | grep NFS NFS Server on localhost 38467 Y 20092 NFS Server on 192.168.5.153 38467 Y 9281 ## pick port number nfsclient # mount nfs://$nfsserver:38467/$vol /mnt/$vol note: - 5. dom0: running kernel-nfsd or glusterfsd-nfs only, not both yet.
