ubuntu 14 在安装过程中选择了全盘安装ubuntu之后 需不需要再进行分区

Question

你好，请问一下，我在ubuntu的安装向导中选择了，全盘格式化安装ubuntu ，系统自动分配了挂载。请问在安装完成之后需不需要在进行手动对磁盘分配空间，
执行sudo fdisk -l 之后有如下结果

   Device Boot      Start         End      Blocks   Id  System

执行df命令之后有

 zjyyy@zjyyy:~$ sudo df -h

Answer 1

应该不用。
fdisk doesn't currently handle LVM volumes (or GPT partition tables) ;
use
$ sudo parted -l
instead.
