rpm error - Can not run any package

Question

I try to install some package using yum, but there is a big problem, I don't know how to solve it. Please help me, thank so much!^^

This is yum error:

[root@localhost rpm]# yum
rpmdb: /var/lib/rpm/__db.001: Input/output error
error: db3 error(5) from dbenv->open: Input/output error
error: cannot open Packages index using db3 - Input/output error (5)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed
[root@localhost rpm]#

after that, I try to re-build rpmdb but:

[root@localhost rpm]# rm -rf /var/lib/rpm/__db.00*
rm: cannot remove `/var/lib/rpm/__db.001': Input/output error
rm: cannot remove `/var/lib/rpm/__db.002': Input/output error
rm: cannot remove `/var/lib/rpm/__db.003': Input/output error
rm: cannot remove `/var/lib/rpm/__db.004': Input/output error
[root@localhost rpm]#

And this is list file and permission:

[root@localhost rpm]# ls -l
ls: cannot access __db.001: Input/output error
ls: cannot access __db.004: Input/output error
ls: cannot access __db.002: Input/output error
ls: cannot access __db.003: Input/output error
