En un sistema Lion Server (10.7.3 y 10.7.4 probado) con múltiples unidades conectadas a un controlador SATA HPT, hay algún proceso que sigue accediendo a las unidades de disco duro exactamente cada 20 segundos. Como resultado, las unidades nunca se duermen (y se apagan).
El patrón de acceso a la unidad no es en paralelo, sino secuencial dentro de un marco de tiempo de 1 a 2 segundos.
Resolución
- Incluso cuando los discos son sin montar y expulsado por diskutil, el acceso al disco continúa a un ritmo de 3 veces por minuto.
-
iosnoop no da ninguna pista sobre qué proceso puede estar causando este acceso frecuente al disco. Hay muchas líneas como:
0 1 W 47880 4096 launchd ??/<unknown (NULL v_parent)>/<unknown (NULL v_name)> dtrace: error on enabled probe ID 4 (ID 992: io:mach_kernel:buf_strategy:start): illegal operation in action #3 at DIF offset 0 0 1 W 2566032 8192 launchd ??/<unknown (NULL v_parent)>/<unknown (NULL v_name)> 0 1 W 2567040 8192 launchd ??/<unknown (NULL v_parent)>/<unknown (NULL v_name)>

Lo extraño es que iostat no rastrea ninguna actividad del disco, aunque los LEDs de actividad de la unidad se encienden, y escuchan una pequeña cantidad de actividad de la unidad. En la salida de abajo está el disco6 desmontado y expulsado y el disco7 montado.
$ iostat -dw 1 disk{6,7}

Los discos duran mucho más si se mantienen a una temperatura constante; girar hacia arriba y hacia abajo todo el tiempo causará ciclos de calor que matan los discos.

Es muy extraño que incluso sin montar algo los esté encuestando. Mi sospecha es que no es el núcleo del sistema operativo, sino el propio controlador o algún software que está leyendo intencionadamente el árbol de dispositivos y husmeando en las cosas para controlar la situación. Time Machine y Spotlight no intervienen cuando un volumen es desmontado, así que mira las aplicaciones 3PP y quizás investiga las especificaciones técnicas de tu controlador. Parece extraño que un controlador SATA hable con unidades SCSI, pero tal vez eso también esté bien en su hardware específico.

@Chris S: hay otros dispositivos y unidades que generan calor y los ventiladores del chasis están termocontrolados por un sensor que se encuentra en el compartimento del disco.

@bmike Creo que estás cerca con "algún software que está leyendo intencionalmente el árbol de dispositivos"

Podría ser un problema de hardware.
