If you want a quick install for Lubuntu 14.04, please, read this post ;)
We installed Lubuntu into a Cubieboard2. But the NAND is using just 2GB of 4GB available:linaro@cubieboard2:~$ df -h Filesystem **Size** Used Avail Use% Mounted on /dev/root **2.0G** 1.2G 698M 64% / devtmpfs 406M 4.0K 406M 1% /dev tmpfs 20M 4.0K 20M 1% /tmp none 82M 208K 81M 1% /run none 5.0M 0 5.0M 0% /run/lock none 406M 4.0K 406M 1% /run/shm none 100M 12K 100M 1% /run/userlinaro@cubieboard2:~$ cat /proc/partitions

We need to work from a Live OS. Install Cubian into the microSD from its great wiki and connect to a monitor or you can use SSH too (There is a solved problem. You have to use the port 36000, user cubie, password cubie:ssh -p 36000 cubie@The_Cubian_IP)
Discover your current NAND partition (as root):
root@Cubian:~# nand-part | tail
3 partitions
partition 1: class = DISK, name = bootloader, partition start = 32768, partition size = 131072 user_type=0
partition 2: class = DISK, name = rootfs, partition start = 163840, partition size = 4194304 user_type=0
partition 3: class = DISK, name = UDISK, partition start = 4358144, partition size = 3375104 user_type=0
We will play with the numbers now. See the colours ;)
`nand-part -f a20 /dev/nand ``**32768 **"**bootloader** **131072**" "**rootfs ****7569408**"`
`fsck -f /dev/**nandb**
resize2fs /dev/**nandb**`
What did we do with nand-part?
* `We joined nandb & nandc.`
* `-f a20`: It's for the Cubieboard2, with its CPU A20
* `**32768:**` it's where is starting the first sector
* `**bootloader** **131072**`: Will not change, then we will put the same partition name/size
* `**rootfs ****7569408**:` This is the key:** **```
**4194304**
```****** + ******```
**3375104 =**
```******7569408**
Then you need to check the partition by errors with fsck and resize to the 4GB.
Reboot and you'll have Lubuntu into your Cubieboard2 with 4GB! :)
