To correctly troubleshoot your issues, please, ensure you're following _all_ the steps suggested here: http://wiki.ovirt.org/wiki/Troubleshooting_NFS_Storage_Issues In particular: 1 - confirm your node are running the 3.4 kernel (uname -a), as installing the new kernel is not enough. Such kernel _must_ be running; 2 - confirm that your NFS server is configured: - to default to NFSv3 (refer to above wiki page); - with a correct export (refer to above wiki page). Please pay attention to the need of having, on the NFS server, a USER with UID 36. Best if related username is "vdsm";

3 - confirm that your FC17-nodes can "see" the exported mounts from the NFS server by running, on the nodes: # showmount -e <ip_addr_of_the_NFS_server> When all of above steps are confirmed, you can start troubleshooting file-permission issues. In detail: 4 - from the FC17-node, manually mount the NFS share with something like: # mount -t nfs <NFS_server_ip_addr>:<NFS_mount> <temp_mount_point> (in my case: mount -t nfs 10.0.49.14:/storage/NFS /tmp/test_nfs) and then try to: - write a file in /tmp/test_nfs: # touch /tmp/test_nfs/test_file.txt and rightafter check, on the NFS server, its ownership/permission. As said in the wiki page, the test_file.txt should be owned by "UID 36" user and should have 755 file-permission 5 - when the all of this is (succesfully) completed, you can retry adding the NFS ISO-domain from the Engine. BTW: if a previous addition attempt failed, in my case I needed to manually remove, on the NFS server, the file/directory structure that previous attempts generated.
