[Pvfs2-users] pvfs2-NFS error

[BOB LIU]

Dear Sam,

My purpose is to let client very easy to connect to server, no any extra
installation needed in client site. That's why I put NFS on the top of the
system.

The good news is if I changed to 32 bit (version 2.8.2), it works. No such
error.
Is there anyone can give me help to let me understand why 64 bit doesn't
work?

Thanks in advance,

Bob
