原本的使用狀況
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 3.4G 1.7G 1.5G 53% /
devtmpfs 438M 0 438M 0% /dev

shm 438M 0 438M 0% /dev/shm

使用 fdisk 做磁碟分割
# fdisk /dev/mmcblk0
[@more@]刪除第二個分割區，並重建第二個分割區
重新啟動電腦
# reboot
使用 resize2fs 擴大分割區的大小
# resize2fs /dev/mmcblk0p2
resize2fs 1.42.10 (18-May-2014)
Filesystem at /dev/mmcblk0p2 is mounted on /; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 1
The filesystem on /dev/mmcblk0p2 is now 1923584 blocks long.
