Binary package hint: samba
I mount a CIFS share and from time to time the mount becomes invalid and cannot be unmounted. The utility complains that it can only unmount CIFS filesystems:
root@sobek:~# mount | grep jon/h
//tower3/home13/njd33 on /home/jon/h type cifs (rw,mand)
root@sobek:~# ls ~jon/h
ls: cannot access /home/jon/h: No such file or directory
root@sobek:~# df -h | grep -C1 jon/h
df: `/home/jon/h': No such file or directory
root@sobek:~# umount.cifs ~jon/h
This utility only unmounts cifs filesystems.
root@sobek:~# umount ~jon/h
This utility only unmounts cifs filesystems.
This utility only unmounts cifs filesystems.
The bizarre thing is, I can mkdir ~jon/h, and re-mount on top.
How on earth did my mount directory get removed, even with a mount on top? I have not done this intentionally myself.
root@sobek:/home/jon# mkdir h
root@sobek:/home/jon# mount h
Password:
root@sobek:/home/jon# mount | grep jon/h
//tower3/home13/njd33 on /home/jon/h type cifs (rw,mand)
//tower3/home13/njd33 on /home/jon/h type cifs (rw,mand,noexec,nosuid,nodev)
I normally try to mount this on login via libpam-mount (and the hung mount in the example above is one such mount, after a cold boot and single login). However I have seen the unmountable stuck filesystem occur even with a hand-made mount.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Could you attach the configuration and outline the steps used to mount the cifs share?
