    Samba >4GB file move issue

    Hi all,

    First post so apologies if I miss any important details here - just let me know what may help. I was going to try the samba mailing list but it seems too arduous...

    I have a Debian server running a custom kernel and samba 3.4.7. It has a number of ext3 drives mounted to one directory on the ext3 root drive, and this directory is shared. Essentially, the separate drives appear to the client as folders. I am connecting to the server via XP/Vista/Win7 (all exhibit the same problem, i've had it for years).

    I can copy >4GB files from a client to the server fine. I can even copy >4GB files from one folder to another fine. Doing this shows a normal progress indicator with speed/time remaining (seems to copy the file across the LAN back to the server).

    However, I cannot move (cut/paste) a >4GB file from one drive/directory on the server to another. Doing this shows a still (stopped) progress indicator then once the target file hits 4GB in size the copy fails. Doing this with a file <4GB shows the same (stopped) progress indicator however the file moves fine. This appears to move the file directly on the server (no LAN traffic).

    It seems like a large file bug in samba, and ive spent about 4 hours looking for info this morning but nothing seems to explain this problem directly.

    Any ideas?

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    Can you copy the >4GB data from one server to the other? My guess is, given what you have said so far, that the problem is with Windows and not Samba per se.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
