A good first step is to enter "run fsck on root filesystem",
or some such, into your favorite search engine.


1. # touch /forcefsck
    # reboot

2. # reboot
    select rescue mode from grub menu which likely has an fsck option

3. boot into live media rather than your hard disk
    now your root partition is just any old partition to fsck
