今天在網上查找分區方法，發現都是用的fdisk，但自己使用總是出錯，後來請求大神幫忙，發現了一個好用的工具，這裏把具體的使用過程記錄下來。
[root@pc160 ~]# parted /dev/sda
GNU Parted 3.1
使用 /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.

錯誤: The backup GPT table is corrupt, but the primary appears OK, so that will be used.
確認/OK/放棄/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
