Unmount Media

Note: requires kernel 2.4.11 or later

When you try to unmount media that is being held open by a file handle from a process, unmounting is denied. When this occurs you can perform a lazy unmount which unmounts the media immediately allowing you to "safely" remove it. References to the filesystem are cleaned up as they are ended by their respective processes.

To perform a lazy unmount use:

umount -l /dev/node

or

umount -l /mount/point

This method of unmounting is often used by certain GUI interfaces like KDE and Gnome when this trick is used
