如何在android上挂载第二个分区？文件系统是 ext2。大小为 8 GB，此分区上安装了 Linux Ububuntu 13.04 PL。我有错误Device busy。我究竟做错了什么？

The number of cylinders for this disk is set to 3880.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
