1.10 磁盘信息

1、获取硬盘参数
$ sudo hdparm -i /dev/sda
$ sudo hdparam -i /dev/sda | grep SerialNo //获取硬盘序列号

2、测试硬盘读速率
#hdparm -t /dev/sda 

# cat dist-read.sh

#!bin/sh

for((i=1;i<=10;i++));do
echo -e "第" $i "次 \n"

echo "不加缓存的读的速度"
hdparm -t --direct /dev/mapper/centos-data

echo "加缓存的读的速度"
hdparm -tT /dev/mapper/centos-data

done
