samba - Oct 2002 - SAMBA with mounted ISO images

Hey all,

I'm using Samba to share *mounted* ISO images w/ windows workstations. In 
other words, I create a share w/ default write access. Then, I create a 
several folders. Some are for files, while others are read-only and used 
for mount points for iso9660 ISO image files (so the user sees the contents 
of the iso files, not the file itself).

I can mount and share the ISO file contents fine. But I can't umount the 
image (to say, switch to a newer version of the same named ISO file). Even 
though nobody is using the server (windows stations switched OFF), Samba 
seems to maintain a lock on the shared ISO mount point (the folder) and 
won't let the resource be released

If I do a force umount (-f) it doesn't help
If I do a lazy umount (-l), it does work, but it doesn't release the loop 
device.
If I do a losetup -d /dev/<loop_device> it can't release it.

But, if I shutdown Samba, it unmounts/releases fine.

So, is there something I can configure or compile into Samba that will 
cause it to not-lock/cache mounted folders so that one can umount the ISO? 
I tried disabling all the known cache settings in the smb.conf -- didn't
help.

Thanks a bunch!

Hey all,

I discovered that if I terminate my login "token" (or whatever you
call it
where the server has successfully authenticated your name/passwd and 
records this) then the locked folder becomes free after about 60 seconds. I 
tried this by doing a net login /d \\server\IPC$

I also noticed that after logging in, closing any open folders but NOT 
releasing my login session, that there are *2* records in the 
locks/connections.tdb file for my workstation. One of them has the IPC$ in 
the key, while the other is presumably just for the folder. Perhaps I can 
just delete this weird second entry manually to force release the folder 
lock that I'm not using anyway without having to logout/login everytime? :)

I forgot last time:
x86 RH 8.0, samba 2.2.5 compiled from regular samba source.
win2k, sp3 w/s

Thanks again,
Jon
