[Samba] Mac/Samba capacity detection problem

Your problem is the following...
OS X 10.3.x can't cope with seeing Samba shares that are larger than 2 TB.  
If the Mac sees anything larger, in the "info" listing on the share, it will  
tell you the true size (i.e., 2.8 TB), but then it will tell you there is 0  
space left. 
Don't get me started on what a piece of (fill in the blank) Macs are for  
networking. And Netatalk is no picnic either. You'll have the same problem with  
large shares and AFP.
Anyway, the solution is to either: 
a)  partition your hard drive so that any given share can't have more  than 2 
TB of space 
b)  use quotas, and set the quota for the user or group that owns the  share 
to be smaller than 2 TB. 
I use option b. Works like a charm. Took me about 4 months to realize this  
was the problem. Hope I can save you some headaches and heartaches.

We are having a problem between
Linux 2.6.9-prep #12 SMP  Mon Dec 6 12:08:34 CST 2004 x86_64 x86_64 
x86_64 GNU/Linux
(Samba  version 3.0.9-1.fc3)


MAC OS X 10.3.5
Samba version  3.0.0rc2

Basically the issue is that the Mac reports the Linux share as  being 
full, and won't allow files to be copied. 

We are able to  work around it using this method:
Create a folder on the Linux share with  the same name as the folder to 
be copied from MAC.
Then when you try  copy and paste, it will let you select "Replace".

Here's what I'm  getting with the DF command:

Linux server with plenty of free  space:

[root at TeranII ~]# df -H
Filesystem         Size   Used  Avail Use% Mounted  on

5.0T    2.3T   2.8T  45%    /home

Macs with  mounted  Linux drive shows erroneous drive space:

[cinemac:/sbin]  root# df -H
Filesystem                Size   Used  Avail  
Capacity  Mounted on
//USERNAME at AMOS/SOURCE       602G   2.2T  -1.6T   365%     /Volumes/Source

sincityedit:/Volumes/source root# df  -H
Filesystem                    Size   Used  Avail 
Capacity  Mounted  on
//USERNAME at AMOS/SOURCE        602G    2.2T  -1.6T   365%     /Volumes/source

Windows mapped drive to Linux shows  correct  free space:

Directory of Y:\

03/22/2005  09:51a   <DIR>           .
12/30/2004  10:00a      <DIR>     ..
03/22/2005  10:16a       <DIR>          _Admin

0 File(s)         0 bytes
3 Dir(s)  2,765,958,938,624 bytes free

I'm not  sure what I can do to isolate the problem.  Can you give me some
