The mount_nfs manpage tells you: -2 Use the NFS Version 2 protocol (the default is to try version 3 first then version 2). Note that NFS version 2 has a file size limit of 2 gigabytes. Linux used to, and maybe still does, have stability problems with NFSv3, so the default was/is to use NFSv2. FreeBSD has no such problems :) Kris
