samba - Mar 2009 - samba doesn't release external usb device

HI all :-)

Using debian stable (samba version 2:3.2.5-4 ) often I mount ntfs partition 
(using mount.ntfs-3g) of a usb external disk. So I can access from my lan to 
this usb disk.

[usb0]
path=/media/usb0
writable = yes
browseable = no
valid users = nick
[...]

when I finish to use this disk and I try to umount it samba doesn't release 
this the disk:

umount /media/usb0 (or umount /dev/sdXX)
umount: /media/usb0: device is busy

because --> lsof|grep usb0

smbd      29491       root  cwd       DIR      180,1     102400          
5 /media/usb0

if anybody uses this remote share how I should umount the disk?

Thanks!
Pol

as root, you can use 'smbstatus' to list all connections.
Also as root use 'smbcontrol smbd close-share share_name' to close
the given share "share_name".
Close the share(s) you've used for your usb disk.
On very recent samba versions you might need to use:
  smbcontrol all close-share share_name
