unexpected output in sfdisk --version [sfdisk，来自 util-linux 2.23.2]后端盘问题

Posted 2021-02-09 学无牙

虚拟机两个组成部分，镜像文件和xml 配置声明文件

1.根据后端盘做一个镜像文件

[[email protected] images]# qemu-img create -f qcow2 -b xq.qcow2 xq.img 20G   

2.cp一个虚拟机配置声明文件

[[email protected]~]# cp node.xml /etc/libvirt/qemu/xq.xml

解决办法：定义全局变量，语言改为英文 （编码）

export LANG=en_US.UTF-8export LANG=en_US.UTF-8

语言可以用 echo $LANG查看(locale查语言类型）

en_US.UTF-8

[[email protected] ~]# growpart /dev/vda 1

CHANGED: partition=1 start=2048 old: size=4192256 end=4194304 new: size=41940959,end=41943007

 

[[email protected]~]# xfs_growfs /

最后使用lsblk和df -h 查看磁盘情况

 

扩容问题就ok了

扩容问题也是弹性云主机的奥秘所在（通过已有资源，自己分配磁盘大小）

改完编码还不可以试试重启机子
