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 the fsck -y /dev/................. mount file system again. Fsck Command here
