That is what happens when I use the copy command to copy single
files to a samba share.

It seems that the client is sending an unlink command for the file
when a write error happens. If you get a write error while overwriting
an existing file it will be deleted and frees disk space for files copied

That is not really what you want :-)

I couldn't reproduce the problem with truncated files until I started
copying a lot of files a once using the copy command with wildcards.

The client tried to copy each file to the full share and there where less
error messages than filenames displayed.

After that the share contained a lot of empty files.

I had this problems with the following 2 configurations:

		client			server
at work		NT 4.0 WS SP3		Samba 1.9.18p3 on Solaris 2.5.1
at home		NT 4.0 WS SP4		Samba 2.0.2 on Linux 2.0.36

The only difference was that Linux ext2fs is reporting a wrong filesize
of truncated files.

I am not able to do this at the moment.
