主要步骤：

vmware宿主机编辑虚拟机配置扩容服务器磁盘并启动虚拟机

fdisk新建分区

pvcreate新建物理卷

vgextend扩展卷组

lvextend扩容逻辑卷

xfs\_growfs扩容文件系统

1.fdisk新建分区

\[root@6\_90 ~\]\# 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.
