如何在android上安装分区2？文件系统是ext2。大小是8 GB，在这个分区上安装了Linux Ububuntu 13.04 PL。我收到错误Device busy。我做错了什么？

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)

你无法装载已装载的东西：

/dev/block/mmcblk0p2 /data/sdext2 vfat rw,relatime,uid=1000,gid=1000,fmask=0133,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 0

/dev/block/mmcblk0p2 - already mounted in /data/sdext2
