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.

P.S.: please, let's stick discussing on the list.

"Technical people tend to fall into two categories: Specialists
and Generalists. The Specialist learns more and more about a
narrower and narrower field, until he eventually, in the limit,
knows everything about nothing. The Generalist learns less and
less about a wider and wider field, until eventually he knows
nothing about everything." - William Stucke - AfrISPA
