Not to discourage you, but once you get past that you may also find you
have problems with getting locks to survive server fail-overs. See
my last posting I had on the subject was over 2 years ago:
http://lists.community.tummy.com/pipermail/linux-ha/2005-July/015357.html
Nobody replied so I don't think very many people have tried doing locks
on linuxHA NFS. I still don't know what to do about the discussion
on the HaNFS web page, and for the last year and a half I haven't
even worked at the company where I had a linuxHA NFS setup.
