samba - Sep 2004 - large file support >4GB (nt4.0sp5->smb3.0.6-suse9.0-kernel2.4.21)

I am unable to copy a file larger than 4GB to a samba fileserver!

My config:
- client is windows nt 4.0 sp 5 (I tried sp 6 without any change, I tried
w2k, too)
- server (now) is samba 3.0.6 on suse linux 9.0 kernel
2.4.21-99-default/I586
- share is on a reiserfs hardware-raid array with plenty of free space
(explorer correctly _shows_ >500 GB, mapped as ntfs drive)

Every time I try to copy a large file > 4GB to samba, nt explorer seems to
be busy for some (10-30) seconds without reasonable data transfer (switch
leds rarely blinking). As soon as data transfer seems to start (I tried it
with a 3 GB file which worked fine), nt explorer shows a message
"<file>
cannot be copied, reached end of file (EOF)" (translated from german error
message, so don't take literal!)

There were some hints in the newsgroups but all say this should be fixed
since 2.2.x, so now I use 3.0.6 and the problem did not disappear.

My odyssee from samba 2.0.x by 2.2.11 to 3.0.6 and hours of reading this
group end up now here in another request for this. I cannot help anymore,
this problem drives me nuts.

So, is anyone here to solve this? More infos and log files are available,
but there's too much to post it unrequested!

Nowadays (2004!) it should be possible for samba to handle files > 4GB,
shouldn't it?

Many thanks in advance!

hi,
i recommend using ext3, suse is good in reiser,
but with ext3 youre on the safe side.
Upgrade samba to 3.07 from ftp suse.com.
have you played with use sendfile = yes ( which works under suse 9 kernel )
and other performance parameters in samba,
like
socket options = TCP_NODELAY SO_KEEPALIVE SO_SNDBUF
checking in general all nics and switches so as logs might help.
i have a equal setup but no such big files to test
have you test the file coping from a win 2000 client with large memory
file handling is only related to partition type ( ext3 , xfs, reiseer )
should be ok.
Just as a test, setup ftpserver on the samba server and try to copy the 
file via ftp.
Regards
