samba - Feb 2003 - how do i umount a device busy ?

I have mounted a win98 machine from a ML8.1 samba 2.2.2

The win98 machine, as all windows machines do, crashed on me. 

Now i can't unmount the mounted folder, If i do it from cli, i get

umount usr/Cad12: device busy.

If i try and cd to that folder, the console freezes and only kill
application will shut it down.

I tried as su and on another Virtual console as root, but it will not
umount. I've shut down the win98 machine and powered it up again. But it
still will not umount.

Also how do i kill a virtual console which is not responding.


Many thanks

Ken

Try

#lsof /usr/Cad12

to find which process to kill.

When you try to unmount a filesystem and are denied with a Filesystem
Busy message, use lsof to determine what process is holding onto the
mountpoint. For example:

# /usr/sbin/lsof /mnt/cdrom

In this case, /mnt/cdrom is the mountpoint in question, and lsof will
tell you if any processes have opened any files on that particular
filesystem.

Did you try "fuser -km /<mount>" to kill all processes accessing
it then
umount device?

Hi,

Would it be appropriate to do a killall {smbd,nmbd} ?

Seems like its down to drastic measurs.

We have applied a patch to solve this issue, so that you will still be
able to unmount the share. This has gone into samba-2.2 cvs, but you can
use these RPMs:

http://ranger.dnsalias.com/mandrake/mandrake8.1/samba-2.2.7a/

IIRC this patch was used on for Mandrake 9.0, and is definitely in for 9.1.

BTW, I search the digests daily for mandrake, I almost missed your post
since you used ML8.1 ...

Buchan
