I am a newbie at the developer's forums and don't know whether to post this in General or Developer's Section.
I recently installed a stock based Custom ROM and had EXT4 Manager in it from default. I saw some options in it which gives 4 different partitions on my phone.
/System
/System/sd
/data
/cache
I hgave about 60 MB free space in system partition. I wanted to ask if there is any use of this space or if I could decrease this partition's size and increase the size of Data partition??
Please Help

As of last night I'm running CF Root 3 JVK on Gingerbread 2.3.3.
When I tried using the ext4 App to convert the file systems to ext4, it was successful for:
/dbdata
/data and
/cache
However for /system, it says:
Code:
Using: internal sdcard
Converting /system
- Backing up files ...
- Creating ext4 filesystem ...
- Restoring files ...
- Restore failed ! Not enough space ?
- Performing rollback ...
- Creating rfs filesystem ...
- Restoring files...
- Rollback success!
I cleared up some space on my phone and now I have 1.87GB available space on the sd card, and 13.26GB Available space on the USB storage.
and 1.75GB Available Space on System storage.
However I still can't convert /system to ext4.
Any ideas why this might be the case?
You need to free some space on /system to be able to successfully convert it to ext4. Apparently, ext4 needs some extra space for the conversion.
This is explained in the CF-Root main post, or in the CF-3.0 release information.
Okay thanks for that!
All the answers were in the original thread. I was just searching for the wrong terms.
I eventually downloaded Super Manager, activated its root mode and deleted the Aldiko eBook app from /system/app
That freed up enough space to convert /system to the ext4 filesystem!

Hi all... Here there're many dev so maybe i'm so lucky to find someone that can help me....
I'm going to convert my phone's partition to ext4 but i have problem with /data. This because the phone has 4 gb of internal memory that Samsung push under /dev/block/mmcblk0. This memory is partitioned in three part /dev/block/mmcblkop1 (internal SD) /dev/block/mmcblkop3 (/data) and /dev/block/mmcblk0p2 (empty).
How can i format /data into ext4? I tryed different way but the phone doesn't boot. What is the correct way to make it?
My Phone (GT-I9003)
UPDATE: recovery can mount it without issue.... init.rc not.... why???
I am a noob. So, please can anyone explain what is the difference between ext2, ext3 and ext4 partition??? and which partition and application is best suitable for x8 as it has low internal memory and y???

Well, If I´m not wrong, ext2 is the primitive file system used on linux based system. ext3 and 4 are evolution of it. I´m using ext4 on my X8 without any problem, but it depends on kernel support.
You could get more information about file system here.
I´m using link2SD, besides the rom have App2SD native, but it wasn´t installing apps on sd-ext partition.
I've been playing around with the CM-mod/S7 and can sucessfully make it boot with all ext4 partitions.
Backround information:
Parititions and formatting
Partitions are the basic unit of storage on my devices with storage (think C: D: E: if you use windows)
The standard layout of android devices:
A /cache partition
A /data partition
A /system partition
Other hidden partitions (this part isnt relevent to us)
The common filesystem formats for recent android devices are EXT 3 and 4 (4 being the newer obviously)
The S7's default partitions:
stock 3xx: (ie froyo)
/cache: ext3(?)
/data: ext3(?)
/system: ext2
stock 5xx: (ie honeycomb)
/cache: ext3
/data: ext3
/system: ext4
my ext4 mod:
/cache: ext4
/data: ext4
/system: ext4
All other devices that launched with HC installed use all ext4 partitions.
But the S7 didnt launch with HC, it launched with froyo.
Dell couldnt upgrade /data to ext4 without wiping user data.
They could upgrade system, since they wipe it on install anyway.
Cache they didnt for the outside chance a user had actual important data in it.
My proposal
What I propose is a modified version of CM9-mod with /cache and /data formatted as ext4 partitions.
I've already got a working version, the main issue is that:
I dont know what the difference is. I've ran quadrant with ext4 and again with ext4, and there's very little difference.
Since quadrant has an I/O and database benchmark (and they run on /data), at least it shows that there's only 1% change in scores.
Would anyone actually be interested in using an ext4 mod?
There are some downsides (depending on how you view it):
ext3 and ext4 nandroids arnt compatable
You will need to do a fac reset on first install (as it reformats)
You will need seperate versions of CM9-mod and CWM
This space for rent
A simple modification of the boot.img to change init.streak7.rc mount points to ext4, easy as pie.
Yea that's what I did, along with a CWM recovery.fstab mod.
But like I said I havnt really noticed any changes in quad, and it's using /data for it's tests
As soon as I get wifi up and working on cm10, going to see if there is any benefit to switching

There is 1.35GB free space in /system partition but only 40MB free space in /data partition on my phone.
Is there a way to repartition the internal storage so as to make use of the large free space in /system partition?

I've got the answer. The /data and /system partition is swapped in CM10 20120820 nightly build.
May be I should use CM10 20120814 version to get the bigger /data partition back.
That would slow down your apps and you wouldn't be able to make use of new features and fixes. Move some of your apps to sdcard and remove unused ones and there shouldn't be a problem.
You could, by that defeats the purpose of what pawitp just did. Move apps to sd.

If you need the extra space create an ext4 partition of around 1gb on your external sdcard and install Link2sd from the play store. That's a universal solution for all phones with limited storage.
Someone has also created a script that does practically the same thing, except it uses the internal movinand where /system is stored instead. http://forum.xda-developers.com/showthread.php?p=30568246
Use Datafix app from market, it makes /data/data directory, where all app cache can be stored.

That doesn't work with JB anymore because of the partition change. Hopefully they update it to make it work.
