## 1.查看现在系统挂载上的盘 ##

## 2.查看所有磁盘，找到要挂载的盘 ##

sudo fdisk -l

## 3.新建分区 ##

sudo fdisk /dev/sdb

如果分区最小输入不是1，则代表之前已经有分区了，若想整个磁盘作为一个区，则应该删除之前的分区。

可以通过命令m获取帮助

可以查看所有设备，发现已经创建好的分区

ls /dev

通过fdisk -l命令查看也行

## 4. 创建文件系统，并格式化 ##

sudo mkfs.ext4 /dev/sdb1

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTMyODgxOTA_size_16_color_FFFFFF_t_70 5][]

## 5. 将新分区挂在到文件系统 ##

mkdir /home/shijianfeng　　\# 我要把它挂载到home下的shijianfeng目录上面

mount /dev/sdb1 /home/shijianfeng/　　　　\#临时挂载，关机失效

vi /etc/fstab　　　　\#编辑/etc/fstab使挂载永久生效

/dev/sdb1 /home/shijianfeng/ ext4 defaults 0 0　　　　\#在/etc/fstab的最下面写入此行内容

## 7.给该文件系统增加写入权限 ##

sudo chmod 777 /home/shijianfeng
