A few questions:
- What kernel version is Cent OS 6 using? I'm running 3.2.7 (on Archlinux, though) and those tests pass...
- Is the server Cent OS 6, too?
- Do you still get the warnings if you run with -f instead of -t?
- Have you tried increasing your "timeo" value? 7 seems somewhat low...
My `mount` output looks like this:
davros:/home/bjschuma/ on /nfs type nfs (rw,relatime,vers=3,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.122.1,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=192.168.122.1)

Thanks Bryan for reply.
Cent OS 6 is using 2.6.32-71.el6.x86_64 kernel.
My server is netapp filer.
I have increased timeout, but still same warning messages.
If I execute by using -f option, non-native 64 bit LFS locking
testcases are passing, but native post-LFS locking testcases still
give same warning messages

Do you have admin access to the Centos machine? I've only been able to find Centos 6.2 isos, not 6.0, so I haven't been able to reproduce your setup exactly. Using nfs-utils 1.2.3-15 and kernel 2.6.32-220 I only see one warning against a Netapp server, and it's been there for as long as I can remember (I've seen it against Linux, too). Warnings probably aren't anything to worry about, and if it is a bug it might go away after the machine is updated :).
