就是我们分配给linux的磁盘阵列的 2T 的空间

我们做如下的操作:

1)fdisk /dev/sdb  

输入m

    Command (m for help): m   

    写分区表

    2)Command (m for help): p      如图5、6

    3)添加一个新的分区，分区号为1

    Command (m for help): w      如图7

    4)下面要加载文件系统，选择ext3文件系统进行加载

[root@localhost ~]# mkfs.ext3 /dev/sda      如图8

5)建立一个文件夹

mkdir /pz

    6)把文件系统挂接到linux上去

    mount /dev/sdb  /pz

    7)确认挂载成功

    [root@database1 /]# df -m

文件系统               1M-块        已用     可用 已用% 挂载点

/dev/sda3               119001      3184    109675   3% /

/dev/sda1                   99        12        83  13% /boot

tmpfs                     3988         0      3988   0% /dev/shm

/dev/sdb               2052141       199   1947700   1% /pz
