[CentOS] Interesting faillog files.

Hi all CentOS users,

I looked /var/log/messages log file and i realize something in
"messages" files like below;


---
Oct 24 04:02:42 cube2 kernel: Buffer I/O error on device sdc, logical block 1545
---

"sdc" is my storage and i switched off storage at 6 PM.

and when i checked messages log file,I saw faillog under /var/log
directory like below:

-rw------- 1 root   root   137438953440 Oct 24 15:39 faillog

its  ~136 GB but my disk table size like below:

/dev/md1              497G   19G  453G   4% /
/dev/md3              157G   15G  134G  10% /backup
/dev/md0              243M   21M  210M   9% /boot
tmpfs                  32G     0   32G   0% /dev/shm
/dev/sdc              805G   25G  739G   4% /mnt/sdc


Where is ~136 GB faillog file ? I tried force fsck but no error i have.

but i worried,Something is wrong ? I have a error about disk ?

If you help me,I will be happy.
