pve，esxi都是用lvm管理分区，可以使用lvm扩容分区

• 启动emmc里的pve
• 扩充的是local-lvm（local主要是VZDump备份文件, ISO镜像, 容器模板，local-lvm主要是 磁盘映像, 容器）
• 使用putty、xshell一类的软件通过ssh进pve，端口22，用户名root，密码是安装pve时设置的密码

扩容前

检查可能出现的情况

fdisk -l

如果提示

GPT PMBR size mismatch (67108863 != 121634815) will be corrected by write.

执行

apt-get update
apt-get install parted
parted -l

Fix

扩容分区

安装需要的软件

apt-get update
apt-get install parted

执行

fdisk -l
