Hola.
Tengo el siguiente problema. Un maquina con CentOS 5.4 (Final) y tiene RAID 1 por hardware, este equipo esta dejando el siguiente registro en el "/var/log/messages" corresponde a un error de disco, pero no se porque, o como solucionarlo.

Este error esta sucediendo con frecuencia (cada 30 min. aporx.) supongo que debe ocurrir por algun tipo de lectura/escritura en uno de los discos
En el arranque se encuentra el siguiente registro en "/var/log/messages":
