# 1、添加硬盘并查看 #

# 2、fdisk创建分区 #

# 3、创建物理卷 #

# 4、创建卷组 #

# 5、创建逻辑卷 #

# 6、指定文件格式并挂载 #

## 1、添加硬盘并查看 ##

###### 1、首先你需要添加一块20G的硬盘,然后重启 ######

## 2、fdisk创建分区 ##

[root@localhost ~]# fdisk /dev/sdb

#### 如上图，执行三次，创建3个5G分区 ####

可以按 p 进行查看

[root@localhost ~]# pvcreate /dev/sdb1 /dev/sdb2 /dev/sdb3

![在这里插入图片描述][20191225101535753.png]

## 4、创建卷组 ##

[root@localhost ~]# vgcreate xcloudvg /dev/sdb1 /dev/sdb2 /dev/sdb3

![在这里插入图片描述][20191225101624592.png]

## 5、创建逻辑卷 ##

[root@localhost ~]# lvcreate -L 12G -n xcloudlv xcloudvg

![在这里插入图片描述][20191225101725551.png]

## 6、指定文件格式并挂载 ##

查看逻辑卷的位置

[root@localhost ~]# lvdisplay |grep xcloudlv

挂载到mnt目录下，并查看

[root@localhost ~]# mount /dev/xcloudvg/xcloudlv /mnt/
    [root@localhost ~]# df -Th
