今天在网上查找分区方法，发现都是用的fdisk，但自己使用总是出错，后来请求大神帮忙，发现了一个好用的工具，这里把具体的使用过程记录下来。
[root@pc160 ~]# parted /dev/sda
GNU Parted 3.1
使用 /dev/sda

错误: The backup GPT table is corrupt, but the primary appears OK, so that will be used.
确认/OK/放弃/Cancel? ok
警告: 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 1828479744 blocks) or continue with the current setting?
修正/Fix/忽略/Ignore? fix
