Public bug reported:
I am not sure if this bug is in VirtualBox or is something deeper.
I mounted a .img file to /media and then tried to share it to the
windows xp running in VirtualBox. When I selected the folder VirtualBox
crashed meaning it wouldn't respond to anything with the windows window
blackened and the shared folder window also dead. I had to kill all
processes linked with VirtualBox from the terminal and when the
VirtualBox was zombified I still couldn't get rid of the VirtualBox
opened windows. So I tried xkill to kill the opened windows since
(theoretically) everything associated with VirtualBox was dead. xkill
did the trick and everything closed. Then I went to the mount point with
nautilus and when I clicked to open the folder nautilus froze with
Uninterruptible trying to do I/O on the folder I guess. From what I
read it is impossible to kill an Uninterruptible process so I tried to
unmount the damn mounted .img but it said the device is busy. I finally
manage to unmount by using umount -l trying to force some exception in
the I/O in the kernel but still nothing, nautilus is Uninterruptible. I
tried to remount the folder but I couldn't since it said it's busy, so
now I am stuck with an open nautilus process that cannot be killed!
I do not know whether this is a VirtualBox bug, a mount bug, a nautilus
bug or a kernel bug! Any help killing nautilus is appreciated since
rebooting is not an option!
Also running ps aux | grep nautilus I get
user 23726 0.2 0.0 738636 1296 ? D Feb26 27:59 /usr/bin/nautilus
Doesn't this mean that nautilus is Defunct? So why am I getting Uninterruptible
in System Monitor?
