[Samba] File System Size Limits?

Is there some limit on the size of a file system which can
be shared via samba?  I'm trying to set up a file server
with a 100GB shared partition and it doesn't want to work.

I'm running Fedora Core 4, and Samba Version 3.0.14a-2.

The output from testparm looks like this:

[root at stitch samba]# testparm
Load smb config files from /etc/samba/smb.conf
Processing section "[homes]"
Processing section "[printers]"
Processing section "[haldisk]"
Loaded services file OK.
Server role: ROLE_STANDALONE

# Global parameters
[global]
         workgroup = HOME
         server string = Stitch
         null passwords = Yes
         log level = 1
         log file = /var/log/samba/%m.log
         max log size = 50
         socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
         domain master = Yes
         dns proxy = No
         idmap uid = 16777216-33554431
         idmap gid = 16777216-33554431
         hosts allow = 192.168.1., 127.
         cups options = raw

[homes]
         comment = Home Directories
         read only = No
         browseable = No

[printers]
         comment = All Printers
         path = /var/spool/samba
         printable = Yes
         browseable = No

[haldisk]
         path = /opt/data
         write list = harold
         read only = No
         guest ok = Yes

This works OK.  the /opt filesystem is only 5 Gb in size.  If I
simply change the line "path = /opt/data" to "path = /bigdisk/data"
where the /bigdisk file system is 100GB is size, and restart smb,
all attempts to  connect to the file system give the following
error on the windows box (smb name is piglet)

  "\\stitch\haldisk is not accessable"
  "The Network Name cannot be found"

and the following errors appear in /var/log/samba/piglet.log
[2005/06/24 10:15:58, 0] lib/util_sock.c:read_socket_data(384)
   read_socket_data: recv failure for 4. Error = Connection reset by

   '/bigdisk/data' does not exist or is not a directory, when

   '/bigdisk/data' does not exist or is not a directory, when
connecting to [haldisk]

(log level = 1, anything higher and I get far too many message to
digest)

The file systems in question look like this:

/dev/hda2               505636    146754    332777  31% /

/dev/mapper/VG0-LV07 101573920     94280  96236760   1% /bigdisk

Hardware consists of two 200Gb Western Digital drives in a
software raid1 configuration.  The Linux LVM is used to create
the file systems on the defined raid device.

I have spent the last two days searching the web for anything which
might explain this.  Any ideas why this strange behavior?  Anything
else you need to see?

Thanks for any help you can provide.
