[Froyo] Ext4 module - Galaxy 3 General

First EXT4 Module compiled with the newest opensource kernel from samsung :
insmod jbd2
insmod ext4
I successfully created a partition formatted ext4.
/dev/block/mmcblk0p3 /mnt/sdcard/sdext4 ext4 rw,relatime,barrier=1,data=writeback 0 0
This need to be tested.

downloading ...and how to convert the partition ?

To convert, we need to make a script (IE: lagfix script)...
I dont know yet what is the best way to use EXT4 :
- Lagfix
- Custom recovery
- ....

[Q] Best combination of filesystems?

what is the best combination of filesystems for galaxy 3? I'm using fugumod 2.2BE, and i want to convert filesystems for data/cache/system because in fs.current all filesystems are rfs
My opinion:
System (stl6) = ext4 or ext2
Data (stl7) = ext4
Cache (stl8) = ext2
thank you, ill trust your opinion

Flash fugumod kernel (if you dont have it already), and make a .txt file and write:
stl6 ext2
stl7 ext4
stl8 ext2
Save the file and rename it to fs.convert. Put it in /sdcard/Android/data/fugumod/ and reboot your phone.
trying it now but I am stuck 5 mins at GT-I5800
EDIT: worked tyvm
I do that but after the phone has rebooted I get a Notification "Low on space". "Internal phone storage is getting low." How do I sort the phone to get rid of this message ?
bjlabuk
ext4 is uses more space, so delete a few app.
Thanks
bjlabuk
I use ext2 for all parts, a bit faster than ext4, because of no log
me i use also this combination:
System ext2
Data ext4
Cache ext2

[Q] G3Mod on /system ext2, /cache and /data rfs

Hello.
Can I flash G3Mod Ultimate on /system ext2, /cache and /data rfs?
It says:
Convert filesystems to rfs before flashing kernel.

but all file systems must be rfs?

In the newest versions of G3Mod you can have all filesystems. So no need to revert back to rfs, you can just flash!
Happy flashing!
It was only for the early version. You can flash kernel at any file system you want.

Unfortunately, I converted to the RFS (by FuguMod), and now... What file system is best?

Now I'm using (and as I think almost everyone would tell you round here xD):
System (stl6) -> ext2
Data (stl7) -> ext4
Cache (stl8) -> ext2
And I'm having a great performance (no freezes, almost no lags...). But if you want to, you can try with all the combinations you want and see how it performs

With G3Mod Kernel, all you have to do is create a file named "fs.convert", put it in /sdcard/Android/data/g3mod/ and reboot
In fs.convert file you have to put:
Code:
stlX file_system_type
Where X is the partition number and file_system_type is, well, you know XD.
If you want to convert various partitions in a row, it should be like this:
Code:
stlX file_system_type
stlY file_system_type
stlZ file_system_type
Remember:
Code:
stl6 -> /system
stl7 -> /data
stl8 -> /cache
For example, let's say I want to convert /system to ext4. So i create the file and write this in it:
Code:
stl6 ext4
Reboot, and done
hadi_xman said:

Click to expand...
Click to collapse
In terminal emulator (or adb shell), run the command "mount" and it will list all partition with it's respective format and mount options. Just look for the partitions you want to check

A Little problem!!
I flashed the kernel G3 mod Lite and installed the g3mod app by Dumpy and modified the file systems as said. After that I'm not able to see my partition. I was previously using Fugumod 2.4 beta3 and i had my sd card partitioned using Minitool. But now i can't see my partition even in Titanium BackUp. When changing file systems using g3mod app, i didn't change anything in mmcblk0. It was left as "rfs". Do i need to change it to something else? Thanks.
P.s. Do i need to activate data2sd?I didn't as I was already using App2sd by kyrillos and after this conversion i lost all my user apps. and my phone's free internal memory is now just 85MB. Previously it was 145MB.

How is your mmcblk0 rfs?? It should be ext3 or ext4.
Ah! It was not. I forgot to change it to ext3 or ext4. When using g3mod app i changed the file systems but left my mmcblk0 as rfs. Now I can't access my memory card using My files. And in "SD Card and Storage" menu it says "unavailable".Any suggestions? Would it work if i flashed g3 kernel and used the app again to change my mmcblk0 to ext3 or ext4?

Ya. Try to change SD partition to ext4 using the app. Still confused how did mmcblk0 became rfs?? . Try the app again and see if it works.

The app shows all partitions as rfs by default.. As he said he left mmcblk as it is and changed the others.. Hence the partition got converted to rfs
Quick Question.. If i'm using g3mod app, should i activate data2sd when i'm changing the file systems?

[Q] regarding EXT4 via CWM

hi
i also have an olive pad & in a discussion in that forum i found out that if we use CWM to do to ext it does only ext2 & not ext4(see below link)
link : http://forum.xda-developers.com/showpost.php?p=17028858&postcount=6
now my question is how to do we do EXT4part via CWM as i was told that we
need ext4 to be present on our SG3 for the apps2sd to work on the cooked roms
i do have the madteam apps apk can i use that
thanks in advance & sorry if this question was asked i could not find it

hi
thanks guys let me explain a little more on why this confusion
i also have a HTC tattoo on which i also have CWM
on the tattoo i have the option of converting ext2 to ext4 ie on the system CWM
we dont have the same and im not confy with the above mentioned tools. so will Madteam apps work for me
and again another reason for this confusion is that recently i have been having alot of problems with the cooked roms not working well and i feel maybe this is because of me having ext2 & the cooked roms need ext4.Do correct me if im wrong here

umm.. if u really want to use minitool or gparted.. then y takin so much pain to use cwm to partition.. partition ur sd directly to ext4..
FuguMod and G3MOD kernels are capable of converting file systems of sd-ext partition too
add this line to fs.convert and making the partition through cwm(and btw i think it makes ext3 partitions)
anyways here's the line
Code:
mmcblk0p2 ext4
hope it helps

IF you made a partiton,convert it to ext4-helps a lot (in other ways too because ext4 is far more better than ext2)
the partiton isnt needed for any cooked rom
it is just an addon so we can get more space for apps
If you can specify what kind of problems you are having and on which rom then i can help more

CWM 2.5.1.8 MZ - wipe problem

Hi,
I cant mount and wipe :
/data - it write : cant mount /dev/block/stl7
/cache - it write : cant mount /dev/block/stl8
/dalvik-cache - it write : cant mount /dev/block/stl7 (File exists)
it does not matter if I have JPQ or JPS, deodexed or stock - problem i same ...
any tips ?
Delete all partitions from your sdcard, format it (not in CWM, with a 3rd part program) and then re-create partitions (from CWM).

I did this already and it does not helped as it result to this state
I created partitions with CWM included at Kyrillos 7.0
I checked there are no difference at this CWM and CWM included at Kyrillos.
But I get same issue when I used later stock ROM and deodexed too with G3MOD 1.7 kernel. There was first time I see wipe issue ...
Now I am trying gparted, we will see. ..
OK, tested, I exactly did it like You said and unfortunatelly it does not work, I get same results :-( ... and what worst I will ahve to again move 32 GB of data -**** :-(
any other tips ? different kernel usage etc ?
thnaks for any help ...

when i had this problem once, the filesystems were gone from EXT2 / EXT4 to RFS after flashing a new rom.
i don't know which filesystems u use...
have a look into /sdcard/Android/data/g3mod/fs.current , if u use g3mod kernel. (for fugumod kernel it's /sdcard/Android/data/fugumod/fs.current)
put a file "fs.convert" in /sdcard/Android/data/g3mod/ (or .....fugumod/)
the file looks like attached... (!!! cut off .txt extension !!!)
after that you have to reboot (!!! not into CWM !!!) and WAIT PATIENTLY for the kernel to convert the filesystems.
After that you should have no problems anymore with the CWM recovery.
good luck!
/data + /cache deleted - pfeeeeeeeeeeeeee !
ufff,
as noone knows and nothing work, I tried some stupidity
I changed permission to /data and /cache and tied delete them manually (mean after it there were no /data and no /cache directory.
NO flash JPS helps, no wipe data helped , I though phone were to the hell , as I always stucked at screen lock , then I see some error message setup cant process, forced closure and phone restart .over and over again
I tried flash Kyrillos 7.0 OC and it works - I am back inj game again
anyway I think there have to be made some changes to CWM, because :
- Kyrillos ROM -all wipes and mounts work
- G3 MOd kernel - wipes and mounts does NOT work correctly
- other kernel after apply CWM - wipes and mounts does not work correctly
as i told you: after flashing JPS all filesystems are converted to rfs
you can also use g3modAPP to change it (only under g3 kernel i think)

what does it means to me ? - as Kyrillos 7.0 is JPS based too ...
If I will convert rfs to efs (?) will CWM work to me even at JPS ?
what partitions have to be converted to make CWM works ?
If Kyrillos use rfs too, can be CWM files riped backward from Kyrillos ROM /system to stock/deodexed JPS ?
I need JPS stock + fugumod ultra + 5lockscreen_extended menu + CWM
And I tried CWM at JPQ , same issue - cant mount /wipe

Ok, I will try, I did no tee your post because of some page error (my side ) thanks
if u use STOCK rom there is NO CWM.
Even NOT if u use fugumod kernel.
CWM is included in custom ROMs e.g. Kyrillos' ROM
and in G3mod kernel.
If u want to have CWM you must use one of both.
When u have flashed a stock rom, the filesystems are converted to RFS.
Look into above attached file and u will see what is usually used for partition filesystems.
mmcblk0p2 ext4 (external sd-partition)
stl6 ext2 (/system)
stl7 ext4 (/data)
stl8 ext2 (/cache)
Further, when u wanna use the external partitions on the sdcard u have to use Kyrillos' app2sd script in /etc/init.d
To convert the filesystems is a just suggestion - it should also work with RFS (though i'm not sure about that....)
but you have to look at /sdcard/Android/data/fugumod/fs.current to see what filesystems are used.

no, I am using Fugumod 1366 only, I get best results and most stable instead of G3MOD kernel 1.6 and 1.7
but I am not sure about ext2 vs ext4 someone test it on PC and ext2 get better speed results

How to know whether ext4 is working or not??

Type mount on terminal to check whether ur partition is rfs or ext4

Using root explorer go to /cache and delete all in it.. If it still gives 4.x mb used 31 mb free then it is ext4 formatted
Or flash a kernel with no ext4 support like whitexp or your hells fusion.. If your phone boots up then you are definitely not on an ext4 system
