我正在使用 Ubuntu 14.04。每当我打开 GParted 时，都会收到 libparted bug found 错误：
Error informing the kernel about modifications to partition /dev/sda2 -- Device or resource busy.
This means Linux won't know about any changes you made to /dev/sda2 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.
当我按下忽略按钮时，将打开以下窗口：
但是当我按“取消”时，我得到：
Failed to add partition 2 (Device or resource busy)
我也尝试过fdisk -l并遇到了一个问题：
