我被打败了，在未找到解决办法前只有把sda sdb全部按ssd方式来“优化”了～

#!/bin/bash
#
# /etc/rc.local: Local multi-user startup script.
#

function setup_ssd()
{
        device=$1
        scheduler=$2
        readlink /dev/disk/by-id/$device > /dev/null 2>&1 || return 1
        diskname=`readlink /dev/disk/by-id/$device | sed 's/.*\(sd.\)/\1/g'`
        hdparm -W1a0A0 /dev/$diskname > /dev/null 2>&1
        echo $scheduler > /sys/block/$diskname/queue/scheduler
        if [[ "x$scheduler" == "xdeadline" ]]; then
                echo 1 > /sys/block/$diskname/queue/iosched/fifo_batch
        fi
}

setup_ssd scsi-SATA_KINGSTON_SV100S08AAA0008487 noop
