These messages usually indicate problems on the harddisk. You may also want to check the cable or the power supply. > May 15 15:55:42 backup_a syslogd: kernel boot file is /boot/kernel > May 15 15:55:42 backup_a kernel: ad6: FAILURE - device detached > May 15 15:55:42 backup_a kernel: subdisk6: detached > May 15 15:55:42 backup_a kernel: ad6: detached > > Does this mean the controller is reporting the disk is gone? When the driver detects a timeout on a device, it attempts to reinitialize the children, and if that fails, the driver gives up and tries to detach it --- at least that's how I read the code.
