"umount -f" je iba na unmountovanie nefunkcnych sietovych filesystemov - napr. ked mas namountovane nieco cez sambu a padne ten server alebo siet - kazdy program, ktory sa pokusi pristupovat k tomu filesystemu ostane zablokovany, vratane umount a musi sa pouzit "umount -f".
"umount -f /" nefunguje:
Kód:
root@pentium:~# umount /
umount: /: device is busy
umount: /: device is busy
root@pentium:~# umount -f /
umount2: Device or resource busy
umount: /: device is busy
umount2: Device or resource busy
umount: /: device is busy
