Estoy tratando de precisar cuál rejecting I/O to offline devicees este error, como se ve hacia el final de este syslog.
Ideas:
- Problema con la configuración RAID-0 (tenemos 2 discos de 4TB en RAID-0 y sí veo un aviso al respecto)
- CD virtual: no hay ningún CD en este servidor, pero sí tenía un CD virtual conectado a una herramienta IPMI/KVM para la instalación. Sin embargo, eso no debería adjuntarse ahora, pero veo algunos mensajes al respecto.
Aparte de las notas anteriores, esta es una nueva instalación de ubuntu 12.04 que se realizó a través de netboot y mediante la consola IPMI/KVM.

Actualizar:
@jordanm y otros: correcto, acabo de confirmar que este es el dispositivo CDROM, pero es un "cd virtual" creado mediante una sesión KVM anterior a través de IPMI en el servidor. Ya no existe, ¿alguna idea de cómo puedo deshacerme de él? O no intentar acceder a él, no estoy seguro de por qué está ahí.
