Linux : Cannot Access .... Input/output error

/bin/ls: reading directory .: Input/output error
total 0
The above error indicate that i cannot access to the specific file on Linux, Delete not working. with root user as well.
so the error is not a problem to delete files, it's a problem about the file system itself and/or an hardware problem, but before announce that it's hardware issue :) try the below solution :-

 Option #1:-

use command dmesg.

(display message or driver message) is a command on most Linux- and Unix-based operating systems that prints the message buffer of the kernel. Read about that command here

Option #2 ( worked for me)

Use Fsck command to detect filesystem error and fix it.

How !!!

 First Umount File system ( that file located ). Using Umount command if it's not able to un mount the file system use lsof command or fuser to check which user using this filesystem.run the fsck -y /dev/................. mount file system again. Fsck Command here
