本文详细介绍了如何在vSphere 6环境中为运行CentOS7的虚拟机增加硬盘空间。步骤包括在vSphere客户端中操作扩展硬盘，然后在CentOS7系统内部进行分区、创建PV、LV，并最终扩展文件系统以实现扩容。

env: vsphere6 虚拟机centos7（2C+2G+30G）

目标：centos7（2C+2G+60G）

1. 在vSphere Client上直接扩大虚拟机的硬盘空间或者挂载一块新硬盘。

2. 查看当前文件系统信息

[root@big ~]# df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   27G  4.0G   23G  15% /
devtmpfs                 908M     0  908M   0% /dev
tmpfs                    920M     0  920M   0% /dev/shm
tmpfs                    920M  8.9M  911M   1% /run
tmpfs                    920M     0  920M   0% /sys/fs/cgroup
/dev/sda1               1014M  142M  873M  14% /boot
tmpfs                    184M     0  184M   0% /run/user/0
[root@big ~]#

3. 查看磁盘分区信息

[root@big ~]# fdisk -l

Disk /dev/sda: 64.4 GB, 64424509440 bytes, 125829120 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000b7e05

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048     2099199     1048576   83  Linux
/dev/sda2         2099200    62914559    30407680   8e  Linux LVM

Disk /dev/mapper/centos-root: 29.0 GB, 28982640640 bytes, 56606720 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes


Disk /dev/mapper/centos-swap: 2147 MB, 2147483648 bytes, 4194304 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

4.创建新分区、设置分区类型

[root@big ~]# fdisk /dev/sda
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
