Linux force file system check

In Linux, you can not run fsck in the normal runlevel or with the file system in use.
You need to do that in single user mode by running "init 1"
or use the trick mentioned as following:

shutdown:

     The -f flag means 'reboot fast'. This only creates an advisory file /fastboot which can 
     be tested by the system when it comes up again. The boot rc file can test if this file  
     is present, and decide not to run fsck(1) since the system has been shut down in the 
     proper way.  After that, the boot  process should remove /fastboot.

     The  -F flag means 'force fsck'. This only creates an advisory file /forcefsck which  
     can be tested by the system when it comes up again. The boot rc file can test if this 
     file is present, and  decide to run fsck(1)  with  a  special 'force' flag so that even 
     properly unmounted file systems get checked. After that, the boot process should  
     remove /forcefsck.
