anyone have any idea about this problem and how can i debug/fix it?
Do you have python-ctypes installed?
Besides iotop does not work for kernels < 2.6.20. You need a patched kernel. The rpm package from http://guichaz.free.fr/iotop/ works also on non standard el5 kernels but shows no more information than iostat.
Further information can be found in https://bugzilla.redhat.com/show_bug.cgi?id=641496 and https://bugzilla.redhat.com/show_bug.cgi?id=557062
