I've made a large .mpg file on a Linux machine (because some
tools, such as mplex, are newer than available in FreeBSD ports).

Here's a directory listing:

-rw-r--r-- 1 jim users 4388444160 Jun 2 23:15 movie.mpg

I want to burn it to DVD but the burner is on a BSD box, so I nfs-mount the /home partition. However when I look at the same file from FreeBSD 5.1 I get:

-rw-r--r-- 1 jim 100 93476864 Jun 3 00:15 movie.mpg

(yes I know there is a time zone issue. I haven't worked out how to set it on Gentoo yet).

The difference between the sizes is 4294967296, ie 2^32.

Anyone know if this is an issue with the NFS implementations
or whether the NFS protocols have a 32-bit size limit?

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 :)

One quick workaround I'd suggest is scp if you have SSH working...
