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.

Oct 27 15:41:16 localhost kernel: ata4.00: qc timeout (cmd 0xa0)

Oct 27 15:41:17 localhost kernel: ata4: EH complete


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":
