方法没问题，但是挂在/data2下面貌似有些不妥，data2目录建了吗？

你这个是LVM

centos 默认分区是
/boot 也就是你这里的 sdb1
/这里是一个LVM分区 就是你这里的 sdb2

你看一下命令：
lvdisplay
里面有什么？

要挂载是要挂载 LV 类似：
mount -t ext3 /dev/vgX/lvXX /mnt

X XX看你情况了。

另要要装一下 lvm2 包。

sudo apt-get install lvm2

找软件方法：
apt-cache search 软件关键字

看你已经装上了lvm2了吧。

打：lvdisplay

查看
ls /dev/vg* 找到相关的。
