我在生产服务器上的 /dev/sdb 上意外创建了属于的 GPT 标签ubuntu-vg。
变更前：
$ df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-ubuntu--lv 88G 74G 11G 88% /
$ sudo parted /dev/sda print
Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all
of the space (an extra 20971520 blocks) or continue with the current setting?
