ubuntu新增加固态硬盘，格式化并挂载到根目录下

前言：将固态硬盘装到电脑，ubuntu系统需要格式化并挂载才能正式使用

将固态装在电脑上后，打开后端

1：查看现有硬盘分区及挂载状态

没有新增的SSD固态硬盘

2：查看服务器所有安装的硬盘状态（包括已安装和未安装的）

此时已经安装的磁盘，但是没有分区，先分区

3, 将磁盘分区，分一个区挂载到根目录下

输入完命令后按回车或者直接按回车就好了

4 在查看磁盘分区情况

现在已经有新的分区了

5 格式化分区

# -t 制定要把磁盘格式化成什么类型

# -c 在建立文件系统之前检查环道，要等一段时间，新硬盘一般不需要

 6 挂载新磁盘

1） 先在根目录下新建一个目录作为一个挂载点

在执行挂载命令

显示挂载成功

7 .设置开机自动挂载

 安装完成后，还可以使用相关命令查看硬盘的读写速度

查看硬盘的读取速度

不同机器的挂载点不一样。使用命令查看挂载点

 Filesystem下面的路径就是挂载点

 liunx下查看硬盘型号和硬盘序列号:
