Oops! I'm sorry. It has another 1 HDD to be used for dump. So, the machine has 11 disks. I think you have already noticed from that RAID5 disk starts from /dev/sdd. I'll send them later.

These are about 600 lines. > [ 1.425771] ata3: SATA link down (SStatus 0 SControl 300) > [ 1.512378] input: PS2++ Logitech Wheel Mouse as /devices/platform/i8042/serio1/input/input3 > [ 1.565064]
