Centos7如何扩容未做lvm的GPT硬盘

背景：一台根分区为2.5T(已转换GPT格式)的虚拟机使用率达到97%，需要扩容，但是又没做lvm

通过平台新增容量1.5T，如下可看到

安装growpart准备扩容： yum install cloud-utils-growpart -y

执行命令growpart报错：

[root@LV7000-801236 2024]# growpart /dev/sda 4
unexpected output in sfdisk --version [sfdisk，来自 util-linux 2.23.2]

解决方法：

[root@LV7000-801236 2024]# LC_ALL=en_US.UTF-8 growpart /dev/sda 4
