To list the mounted filesystems and the device entries associated with each
of these, use the 'df' command.
To unmount one of these filesystems, first make sure that nothing is
accessing the filesystem in question. Once this is the case, issue the
following as root:
umount -v filesystem_name
If you get the message that a filesystem cannot be unmounted because it is
busy, use the 'lsof' command to see which processes are still using that
filesystem. Term any processes holding the filesystem hostage and then try
umount again.
