4EXT/Partitioning Help!

Hello there! if I just want 1gb partition for games,apps, and I got a 8gb card, whats the correct way to do this on 4EXT recovery?
Also one of the things says....
Warning sd-ext2 is not formatted!
how do i format sd-ext2???
how do I go about clearing everything and starting again? there is a option in the wipe/format menu, called Wipe all Partitions (DANGEROUS!), does this clear everything? I dont want to do it without checking with experienced forum members first, so if you can help, please leave below....

You've got one solution
Make a backup from your sdcard on your PC, and format partition and increasing the size of three of them ( system, data, cache, sd_ext and ext2) with your recovery on EXT4.
Like this:
- system => Ext4
- data => Ext4
- Cache => Ext4
- SD-ext => Ext4
- SD-ext2 => EXt4 or Ext3
- sdcard => fat32
then, restore your files on your sdcard.

Use the EXT4 recovery as suggested, although are you sure that you'll need this space as the DS had over 1GB of internal user storage available to you by default. Mine has over 700mb free with all my applications installed.
The un formatted message relates simply to the non existence of the partition and isn't anything to worry about.
To wipe everything, the easiest way is to simply perform a factory reset, either from bootloader or from settings
The wipe all isn't what you are after as this is used by ROM cooks and wipes all partitions, which should only be used when installing new roms

[Q] help with sd-ext partition

I've tried a few different roms on my SK4g, ODIN'd it twice in the process of trying roms.. I decided I'd try the 0bloat rom and saw it supports the sd-ext..
I created a 2048mb sd-ext partition in the RED clockwork recovery partition SD card under advanced.
should it not show up under mounts and storage? I just have:
unmount /cache
mount /data
mount /sdcard
unmount /system
format /cache
format /data
format /sdcard
format /system
mount USB storage
Under the instructions for "Stock 0 bloat KJ2" it says it supports the sd-ext partition. However I don't see it and it doesn't seem to be recognized by the phone.. I took my sdcard out and plugged it into a computer and the sd-ext partition mounts fine and it's listed as ext3.
any suggestions would be appreciated.

uh..
so nobody else does this? no suggestions?

it wont show up under mounts and storage, and isnt even mounted on the phone yet. download an app from the market called LINK2SD. when you first start the app, it will ask what type of partition you have (ext2, ext3, ext4, or FAT32). pick whichever one you have. after a moment, it will say something about mount script created and tell you to restart your device to mount the partition. reboot and the partition should be mounted. you can then install apps to that partition.

I have some doubts :(

What is the difference between ext2, ext3 , ext4 ?? and what are they actually??
I have 8gb class 4 memory card. If i need to make 3 partitions (sd-ext, sd-data, sd-cache) for installing a rom and a kernel in my pico, how much space should i allot for each partition?

well, make both partitions as ext3 if you want to mount external partition in recovery.
I'm using sd-data as ext3 & sd-cache as ext4 & I can mount it in recovery, nandroid backup also works.

[Q] sd card second partition

which one is better? ext2, ext3, ext4 or FAT32? and using what tools I should partition the sdcard?
I am using cm9.2.2
before that, I partition sdcard with Amonra Recovery with ext2 and use link2sd and have a problem, some times sdcard removed unexpected, when I reboot sdcard is not read, I pull out the sdcard and insert, and sdcard read normally. I reboot and sdcard not read again, I do this many time and finally can read sdcard. but it happens over and over again. I try to format the phone and install app, move app like unrooted phone, the sdcard work fine..when I try use ext2 with link2sd some times its happend again.,
help me..sorry for my bad english, I am Indonesian.
thank you before..

If you want to know what other people use to do this here I come:
How I make the ext partition:
Minitool partition wizard (windows)
Gparted (Linux)
Clockwork 6.0 (only for CM10+)
I didn't have any trouble with that programs, but be careful with the Clockwork because formats ALL the SD card, the ext and the fat partition, so make sure you do a backup of the SD.
Format of the second partition:
Always ext4
Link App
Link2sd is the best, other caused troubles over the time (reboots, not reading the sd, not reading the ext partition, etc)

I used ext4 in all CM from 7 to 11 and no trouble, but always formatting after every wipe with gparted or minitool, because Clockwork 5.0 seem to not format well the ext partition, so after every wipe you should reformat with those programs.

From my experience use ext3, it is good and compatible with everything, allmost

EXT4 has a tendency to corrupt

Ext4 works great.

MM internal memory solution

Hi guys,
I'll share some scripts (flashable) that I've made to help with xperia l internal memory shortage.
1. First one is the link2sd-enabler.zip: http://www24.zippyshare.com/v/UduJGjqJ/file.html.
For this to work you'll need a second partition on the external sdcard formated as ext4. So first partition is the vfat one, the second primary partition on the external sd card is the ext4 one. Currently I have a 8Gb ext4 second partition.
Installation procedure: prepare your external sdcard, flash the zip, install link2sd application.
2. Second is the 01link2sdmm: http://www86.zippyshare.com/v/9DSgorlH/file.html.
The link2sd application does not automatically link the oat directory of the application. This directory contains the compiled application in the form of an odex file. For big apps this file is pretty big. So this script will automatically link this directory to the sdcard second partition for the applications that are linked to the sdcard. This works in conjunction with the link2sd-enabler.zip script.
Installation procedure: put this script in the /etc/init.d directory with the proper permissions. This way it will run at boot. If you want to run this directly after you link an app you'll need to use automagic and make a rule to run this script after you exit the link2sd application.
Observations: This script is not needed if you switch the internal partitions because you'll have enough space to keep the odex file internally. It's your choice.
3. Third script is the mm-partition-swapper.zip: http://www10.zippyshare.com/v/eyRO7gLw/file.html.
This one will switch your sdcard and userdata partition on your current mm rom. This was tested on rr573 that I have installed, but it should work in other mm roms as well.
Installation procedure: Make sure you have enough space on the external sd card so the script will be able to save your current data partition files. Save the files that you need from your internal partition to your external sd card. Make a backup of your current rom from twrp in case something wrong happens. Format from TWRP the internal sd card as ext4. Flash the zip. If everything works ok then you'll have a rom with the internal partitions swapped and you'll have 4Gb of user data available (minus your space for the already installed apps).
!!!!!!!!!!!!!!!!!!Very important!!!!!!!!!!!!!!!!!!
Don't try formatting the internal sdcard as ext4 with twrp version 3.0.2! It seems that his twrp version does not support this. I'm using twrp 2.8.7.0 by Barbarosa.
Observations: Twrp does not support backing up/restoring internal sd. If you swap partitions you'll have to backup your ext4 internal sd manually from within twrp connected through adb (with a simple tar command)
4. I think 256 ZRAM for the rr573 rom is too big so this zip will change this to 128MB:
mm-128Mb-zram.zip:http://www103.zippyshare.com/v/XjVAnXEl/file.html.
Please make a backup before flashing the swap zip and report if this worked for you.
Hope this helps,
Thanks.

I've been struggeling for quite some time to get the link2sd app working since I flashed MM.
I've done a clean install, flashed the zip, installed link2sd, but I still get a 'mount script error, Cannot create script, mount: no such file or directory.' Anyone got an idea what I do wrong?
thx!

Check if you have in the /etc/init.d directory the 00link2sd script. For this script to work you need a rom with a working init.d (otherwise this won't work obviously...). If you have the script there, then check if you see a directory /data/sdext2 (if this directory is missing, but you have the 00link2sd script in the /etc/init.d directory, then this means you don't have init.d support in the rom). If you partition your sdcard correctly then the second ext4 partition of you sdcard should me mounted in the /data/sdext2 directory ... All these you need to check before installing the link2sd app...

Awesome! Thank you. I'll try this

I have the init.d folder, but it seems the sdext2 folder was only created after I installed the link2sd app.
I tried doing it all over again, but it still doesnt work, same messages...

Then your rom doesn't have init.d support. You need a kernel/rom (more precisely a ramdisk) with init.d support to use this ... The rr573 supports init.d ... Try it with this one ...

Thx! Which do you recommend? I've tried several in the last two or three months. Now I'm running AOSP-OMS.
I ran slim, RR and CM 13 beta before without any problems, just the storage issue.

I am on stryflex MM ROM and TWRP 3.0.2.
I formatted internal storage as ext4, then flashed mm-partition-swapper.zip.
Says that there is no ext4fs partition and I tried reboot recovery and my phone is dead now, can't turn it on...
I don't blame you, I blame myself for trying. But please help. Flashtool doesn't recognize flash mode.
Don't use this method. Not safe.

Sorry to hear this. If the script gave you this error then the script did nothing to your phone. It just aborted the procedure because it did not find the sdcard formated as ext4. It must be the twrp version. I'm using twrp 2.8.7.0 by barbarosa. I think twrp 3.0.2 does not support formatting the internal sdcard as ext4. Most pobably the twrp version 3.0.2 formated something else as ext4 or whatever instead of internal sd... I did not know this. Sorry again...
Try to search the brick threads. If you still have a blue light when in flashmode I think you still have a chance to resurect it...
Sent from the center of the galaxy

I've modified the post to warn people of this twrp version. So, people, use only twrp 2.8.x.x to format the internal sdcard. I'm using 2.8.7.0 twrp version by Barbarosa. I don't know if other twrp versions support ext4 on internal sdcard.

Thanks for the solutions. So now if I only need to swap internal sd and /data, i just need to flash 3rd script? I'm quite confusing about partitioning and memory stuffs

You have to have twrp 2.8.7.0, then format internal sdcard as ext4 (wipe settings) and then flash the zip...

Yes, formatting internalSD as ext4 is tricky. My recovery was broken. Probably formatted something else. It wasn't your script.
However I have no volume up button on my phone (fell out) - no fastboot. And just volume down button (flash mode) and a somewhat broken USB cable. Phone not recognized by flashtool at all...

Ok thanks! One more question, If I somewhat want to undo this, I need to back up the current MM rom before flashing the script? Will the internal sd and /data automtically be swapped back when I restore the back up?

After swapping the partitions your old backups of the rom will not work anymore (or probably they would just revert the swapping. Anyway if you want to restore a backup that's been done prior to swap it's better to format back by hand the internal sdcard to vfat and data to ext4)
For backing up a rom with swapped partitions you'll have to select the sdcard instead of data partition in the backup options... I did not try it yet...

I ran the the link2sd enabler script on my rr573, works like a charm now.
Thank you so much, I needed this!
Didn't swapped the storages yet.

The dream is real!
Congratulations.
Seeking a long time for a script like mm-partition-swapper.zip
Before seeing your post, I had already made the formatting of SD0 (ext4) to try to install Link2SD to work with SD0 without work.
I used the TWRP 3.0.2.
I could easy return the partition to FAT.
I intend to make a clean installation of ROM on my device to then install your mm-partition-swapper.zip script.
As both the "DATA" as SD0 are empty you still think need to format with TWRP 2.8.7?
No way to change this script without the data transfer?
Only formatting partitions and inverted mounts?
If not necessary then ok...but... please clear this my doubts.
Again without getting tired ... very thank you even for your script.
