[GUIDE] Config EXT+SWAP partition on AlfsKernel+GDX

---

I made this Tutorial for enable ext and swap partition.
I have based this guide on:
- sdparted script (thanks to 51dusty): i modified the script for works on our X8
- on http://forum.cyanogenmod.com (Enabling swap)

Requirements:

- AlfsKernel (i used v03 for this tutorial)
- GDX (i used V019 for this tutorial)
- ADB
- sdcard (i used SD 8GB class 4 -> recomended class 6)

My configuration: (with SD 8GB class 4)

- fat32 -> 7040 MB
- ext3 -> 1024 MB
- swap -> 128 MB (swappiness 100)

Instructions:

1) download sdparted.txt and userinit.txt below to root of sdcard
2) boot into CWM recovery
3) mount /sdcard, /sd-ext (if you have ext partition) and /system
4) backup sdcard: adb pull /sdcard/ sdbackup
5) If you have ext partition and you want backup this: adb pull /sd-ext/ sdextbackup
6) run: adb shell
7) move sdparted.txt to /sbin -> mv /sdcard/sdparted.txt /sbin/sdparted
8) then, chmod 755 /sbin/sdparted
9) run sdparted: for the differents options see the original thread
This is for my configuration -> sdparted -es 1024M -ss 128M -efs ext3
10) restore sdcard backup: adb push sdbackup /sdcard
11) restore sd-ext backup( if necessary): adb push sxtbackup /sd-ext
12) move userinit.sh to /sd-ext -> mv /sdcard/userinit.txt /sd-ext/userinit.sh
13) then, chmod 755 /sd-ext/userinit.sh
14) reboot

Note:
For change swappiness, you must edit userinit.txt before of copy this to sdcard. You must modified line 12 with the value you want:

echo 100 > /proc/sys/vm/swappiness;

Change sdparted.txt, there is error with command -ufs.

exactly what is this swapper for??
i've never used it before

here

make google as your friend..

i use swapper 2 with swap partition and is working perfectly.
i have a swap partition with 128mb,ext 3 with 512mb and the rest in fat32.
my sdcard is a kingston 4gb class 4.

With this, you don't need any app.

This is another option for use swap taking advantages of the kernel, and i think that some users don't know.

ok.i only say that because swapper 2 its noob friendly.

Hi dev,
Just ask questions, what is swapiness?
Whats wrong if swapiness set to higher value or lower value?

you can see this http://en.wikipedia.org/wiki/Swappiness

After some test, for me, the best performance is 100; but for some people is 80. You must test it in your phone with your configuration and apps.

For change it and test without reboot, you can type in console: sysctl -w vm.swappiness=0
