当虚拟机存储空间不够时，VirtualBox虚拟机是不能再修改已分配的硬盘容量的，如果空间不够用，只能添加新硬盘：

### 1、添加物理硬盘 ###

###  2、分区 ###

查看设备

fdisk -l

设备没有识别分区表

fdisk /dev/sdb

输入n,后面使用默认值即可，直接一路回车（默认将当前硬盘建为一个主分区）

建立分区时必有一个是主分区，其它为扩展分区

###  3，建立文件系统 ###

mke2fs  -t ext4 /dev/sdb1 \#ext4创建文件系统

###  4，挂载/永久挂载 ###

临时挂载：mount /dev/sdb1 /worksp

永久挂载需修改配置文件

vim /etc/fstab

设备         挂载点         文件系统类型         挂载参数         是否备份     是否检测
