The kernel needs to support ext4. The stock kernel does not, so if you want to use ext4 you also need to flash a custom kernel.

This script will convert your system & data partition to ext 4 filesystem
only use it when your ROM / KERNEL supports ext4 filesystem ! Read description carefully !
example for use :
use it when you try out MCR ROM FR19 (you have to convert to ext3 before) or CM (will auto convert to ext3 when installing) and want to revert back to your older backup (FR18 for example)
restoring your backup in CWM recovery will restore your data but will not convert your filesystem back to ext4, that´s why i made this zip.
so, if you plan reverting to your backup (which supports ext4), simply apply this zip in recovery & restore your backup afterwards ;
back_to_ext4

This script will convert your system & data partition to ext 3 filesystem

If you have been using a EXT4 ROM and you want to restore a stock ROM that only has EXT3 support, it's a bit of a faff. Introducing BackToEXT3.
This ClockworkMod update zip simply converts your /system and /data partitions back to EXT3. It wipes them both in the process, so you need to have an existing backup / ROM to restore to.

example for use :
use it if you are running an ext4 ROM at the moment and want to revert to your stock ROM or CM backup. (which both only support ext3 at the moment)

Niceee, just what a lot of people need.

quick on phone :
open "terminal emulator" (free in market) on phone
type in command : "mount"
check output

Anyone know if the CM7 (offical) kernel has support for EXT4? Then we could use this to convert from EXT3 to EXT4, right?

you could use, but ...
CM system partition still running ext 3 ...
Code:
format("ext3", "EMMC", "/dev/block/mmcblk0p1");
mount("ext3", "EMMC", "/dev/block/mmcblk0p1", "/system");

I used this backtoext3 in order to return to my nandroid stock rom v10d backup.
Restore completed, but then on boot, it stucks on the 2nd LG logo (one with blue statusbar underneath it).
Am I missing a step here?

I'm working on a universalEXT4converter. It will convert your filesystem to ext4 and edit your ramdisk (works on every rom). Currently not working and I can't bugfix it (because erm something went wrong hehe ).
But will be ready soon and p999 support will follow too

strange ...
it should work for that case ...
you have also changed baseband to newer version , perhaps that´s the reason ?

Well I'm running the latest Slick2x-G which is CM7 and I've tried a new kernel (Morfic's EXT4 Trinity Test Kernel) from OP of this topic http://forum.xda-developers.com/showthread.php?t=1067939
Converted to EXT4 with CM7 and it seems to be running ok, not having any problems, battery life not too bad either.
One thing I was wondering though was I was to wipe and put a different CM7 based rom on without the above kernel would it automatically convert back to EXT3?

Cm update Script formats system ext3 when installing...

Hi i'm new here and i have some question need you guys help.
1)I'm now on stock rom and kernel with ext3 file.Do i need to do anything if i want to load new rom or kernel with ext4 from cwm 5.0.2.0?
2)If my current rom or kernel is ext4 and i want to load back to ext3,what should i do?
Sorry for my bad english.
You don't need to do anything to switch to EXT4, ROMs convert on install. Take a backup of your stock setup, you can restore that to get back to EXT3 as you're using CWM v5.
Thanks you Rusty!
So the newest cwm will automatically convert it to ext4 right?!Except for ext3,i need to convert it using backtoext3 from Paul or restore back to stock.
No.
A ROMs updater-script will convert to EXT4 if it needs it. CWM v5 will convert back to EXT3 when restoring a backup of an EXT3 ROM.
Thanks again Rusty!
I get the picture now!
Hi,
need steps to change rfs to ext4? And does it require data wipe?
I am on SGS I9000 + 2.3.5 stock jvt
Regards.
No data wipe required, flash a kernel with ext4 included, boot into recovery and apply lagfix. Be sure to remove lagfix before flashing another rom in cwm.
Some kernels will require chainfires ext4 tools application.
Go to develop section and have a read up.
no data wipe but for security just make a backup coz sometime it hangs but not everytime.....just convert ur partition.

Now you are on stock ROM. To convert rfs to ext4 either you have to install a kernel that support ext4 and then go to recovery and then enable lagfix. Or you can go for a custom rom. My advice is to go for custom ROM like Darky...

Hello,
I want to know whether the original ROM for ACE support ext2, ext3, and ext4 filesystems. I have partitioned my sdcard in 3 partitions one is FAT32 and the others two are ext.
Thanks.
ext2, yes. its supported even on stock samsung rom with stock kernel.
ext3 and ext4 no, need custom kernel.

Just installed EXT2 for Link2SD on a Samsung Ace stockrom 2.3.5. This works.:good: First tried EXT3, didn't seem to work.
Stock rom plus stock kernel supports ext2 but stock rom with stock kernl doesnt support ext4 or 3
I would recommend you to flash nims kernel and use ext4 type and use ext4 tweak by mr slaid to improve performance
Give it a shot

.ext4 partions works fine in 2.3.5... tested by me
I think you failed the installation procedure
Guys I'm new here and I do not know much about roms or recovery modes and it's functions. I have a question for you. Some of the roms support f2fs filesystem but whenever I try to install them on my device, it flash roms by using ext4 function. I have never be able to flash them by using f2fs. For example Los 13, Los 14.1, RR roms have f2fs filesystem support. I convert my system and cache to f2fs from ext4 but it doesnt work at all. It installs the roms by using ext4 always. How can I flash them with f2fs filesystem. I have heard that f2fs is faster than ext4 therefore I want try it

I have tried that but whenever I try to install a rom with a filesystem formatted as f2fs, it converts it to ext4 at the beginning of the installation. Can I convert my filesystem after installing a rom? For example after the installation of LineageOs 14, can I convert my filesystem as f2fs? Does it harm my phone?
