linux 下挂载磁盘阵列
linux 下挂载磁盘阵列
3.把磁盘阵列挂到linux 系统上来
# fdisk -l

上面的 Disk /dev/sdb: 2186.1 GB, 2186127343616 bytes
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
# 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
# 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 8313% /boot
tmpfs 3988 0 3988 0% /dev/shm
/dev/sdb 2052141 199 1947700 1% /pz
