Oops.  Didn't see that it was working ok with ext2.
You must have already had Samba working.

Hi;

The problem may be with Samba in that you have to make it look
for the 64-bit file size ability (in a header file).  Samba
(even recent 2.2.x) does not do it for Linux by default.
A patch to the 2.2.x Samba tree (SAMBA_2_2) attached makes
Samba look when it compiles.

This all begs the question of what happens if you just use xfs locally
to
do this? Also, where does smbtar run (is it just a user app?) and what
exactly does it do?

We need to get less variables in the picture, not more, try the local
XFS
case and let us know if you can copy and untar the file there - this
will
give use a better idea of where to look.
