甲骨文创建完VPS后，本来设定的硬盘是100G，结果安装完宝塔以后，只显示39G，然后从网上找到教程，按教程操作后，即可显示正常。
命令顺序
[root@sssss ~]# parted -l
Error: The backup GPT table is not at the end of the disk, as it should be.
This might mean that another operating system believes the disk is smaller.
Fix, by moving the backup to the end (and removing the old backup)?
Fix/Ignore/Cancel? fix
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 112037888
blocks) or continue with the current setting?
