[Q] ext4 What is it?! - Desire Q&A, Help & Troubleshooting

I have been using a custom ROM for a while now and I have been seeing in the thread that many people are using ext4.
I have asked many times in the thread and recieved no reply.
So my question to you is what is "ext4" and what bennifit will it be to me as a Desire owner.
Thanks

1. Google is your friend
EXT4 is a file format used by Linux (Android = Linux). When threads talk about EXT4, they are referring to creating an EXT4 partition on your SD-Card e.g. have 14GB FAT32 and 1GB EXT4 (from 16GB SD-Card.. 1GB is always non-existent)
What having an EXT4 partition enables you to do, is to have Apps/Data2EXT scripts which move apps to the EXT partition, giving you a lot more internal space.

Moving some of the app data to the sd-card is different to having an EXT partition and A2SD.
If you activate A2SD, the system will install and store your apps on the EXT partition, and your internal memory will not be filled up, and will remain at xxxMB. Furthermore, with an EXT partition you can use D2EXT, which makes your phone use the EXT partition as the data partition, so if you have 1GB EXT4, your phone will see 1GB memory.
If you use the inbuilt "move to sdcard" function, it only moves some of the sd-card to the android-secure folder on your sd-card, however your internal memory is still used up.

In addition, moving apps to sd-ext partition doesn't break app widgets like the stock app2sd method that Gingerbread use.

Reason: With A2SD / DATA2SD / etc. Android still "thinks and tells" the Apps are still installed in the internal memory (at least this tells me my logic).

I am guessing there is a way to just move to the ext4 via a app?

backup your sd card 1st
then use only 4ext recovery (requires s-off to change recovery) or gparted to create your partition (step 5 here)

How to create usable ext partition for A2SD ?

Okay this is really driving me crazy. I have a bunch of custom ROMs on my system and none of them recognize the ext3 (or ext4) partitions on my SD card. I know for a fact that all of them support the sd-ext partitions. (Obviously, I am doing this for A2SD usability)
I have MIUI 1.7.1, CM 7.0.3 and HiApk (with sensefun) v1.1.
I tried creating an ext3 partition in the beginning of the SD card like this,
400MB ext3 (primary) | 1.6GB fat32 (primary)
I tried doing it the other way round too, like this ->
1.6GB fat32 (primary) | 400MB ext3 (primary)
Neither works. I am using GParted on my Linuxbox to do this. What is the problem ? and how do I solve it ?
I have read quite a bit on all this and none of it is straightforward. Can someone explain it to me, like a 10year old ?
Go to into recovery and partition your sd card there.

I can show you how... check my signature... there`s two youtube guides.
One with Gparted, and one with Minitools.
Enjoy.
how do you know it is not working?
the EXT doesnt add up storage space in 'internal storage' in android settings
you have to use Quick System Info from android market to check if a2sd+ is working
and also
the correct partition layout is FAT32 and then (after fat) EXT partition not the other way.
also try with 512mb ext partition.
To see the ext partition, you can either connect your phone to linux or use an explorer which has root access.

Thank you people ! Yup, got the partition working. Also, thanks to dzumagos for the tip on how to see the ext partition space.

[Q] Pros and Cons of sd-ext?

Hi!
Just would like to know the pros and cons of formatting into ext4 on my SD.
As far as I can find :
Pros : Supports files larger than 4GB as Fat32 cannot
That's about it I think...
Cons : Windows cannot natively detect such a partition
Why I ask this is I just saw a this post

You're mixing things up here a bit I think. Sd-ext referrs to having a partition on your sdcard to allow support for Apps2SD (basically being able to move apps to your SD card and run them from there in order to free up space); you'd basically repartition the card so that there's an ext3/4 partition for apps and a FAT32 partition for data.
As for the ext4 filesystem, it does allow for larger file sizes and is also a bit faster but you're correct in the fact that you won't be able to natively mount it on a Windows system.

But don't we already have Apps2SD in GB, + all the apps that do it for you. How is this different, apart from some apps that can't natively be moved? And why is it faster? Internal memory should always load faster, should it not?

GB has the ability to do Apps2SD but it requires the partitioning as, I believe, a symlink is set up so that partition on the sdcard acts as a part of the devices internal storage.
As for speed, just moving apps to your sdcard won't speed up your phone; what that poster you quoted was talking about (most likely, I'd have to see the original thread) was converting your devices partitions (/system, /data, /cache, etc.) from ext3 to ext4. ext4 is a bit faster however some ROMs do not fully support it.
Sent from my T-Mobile G2 using XDA App
Ok, let's clear this up. GB has Apps2FAT32 (a2sd) natively. A2EXT is completely different but none of that is the point of the OP's question.
When it comes to our phones - there is almost no notable performance gain when using EXT4 over any other EXT format. Our phones don't utilize FAT32 internally - just on the sdcard. EXT4 is designed for use with massive file systems. A couple Gigs really doesn't access it's full potential.
While the question is interesting, I'm not really sure what you're planning on doing. Don't format your sdcard entirely in EXT format, and don't attempt to format your phones partitions as FAT32. The result would be... just don't do it.
Just read this on the portal
http://www.xda-developers.com/andro...hd2-data-successfully-moved-to-ext-partition/
This has two main advantages: larger sized data partition and more speed as EXT is inherently faster for I/O purposes.

How do I go about formatting a section of my SD into ext4, with existing SD data intact.
And how do I move apps that area already in my phone's internal memory to the ext4 partition? I know there's an option in ROM Manager and CWM, but just don't want to mess anything up

As far as I know, only two ROMs actually support the real A2SD: PyroMod and MexDroid. It's recommended you format the EXT partition to EXT4 before you actually flash either of those ROMs, and you have to rename MexDroid in order to get A2SD working.

Thankfully I am already using meXdroid~ Guess I'll just wait for the new version in the next few days to do the formatting. Can I backup all my apps with Titanium Backup, flash ROM (wipe data/cache and dalvik cache), restore with Titanium.
Or would I have to reinstall every app again so that it goes into the ext4 partition?

There's a script to accomplish this on pretty much any ROM. It *should* work on current ROMs too. It's called 'darktremor a2sd'. Still find it amazing people forget about that one when this question comes up because it's one oldest methods of obtaining a2sd.
I'm still not understanding the OP's question. Are you wanting to do this for an IO performance gain or for space? I can understand doing it for space if you have a ton of apps but if you're doing it for performance it's a waste of your time. You're internal partitions should already be in EXT4 format (use 4EXT Recovery if they're not).

I'm doing it for the performance. Have been using 4EXT for a few days and loving it. Already converted internal memory to ext4 from ext3. If further partitioning my SD card for performance is really not noticeable, then I guess I've got nothing to worry about

[Q] SD Card Configuration : Ext and Swap Partition

Hey,I am going to "clean" install CM 7.2 Stable.I am done with Custom MTD Partitions and want to set up an ext partition on the SD card and move apps there.
Preparing for "S2E"(simple2ext:https://play.google.com/store/apps/details?id=ru.krikun.s2e&hl=en )
I have got 2GB SD Card.
What should be the ideal configuration for a 2GB card in terms of :
(1)Ext Size
(2)Swap size
And what should it be ? Ext2 or Ext4 ?
According to this :http://forum.xda-developers.com/showthread.php?t=1432459
“Choose Ext2, Ext3 or Ext4 for partition type based on whether your kernel supports Ext4. If it does choose it! If you don't know choose Ext2 to be safe.” Now how to find out whether your kernel supports it or not ?
Does "swap" really make any difference ?What’s up with this “swap” partition ?
It’s so confusing.Some people claim that “swap” is like virtual RAM and more RAM means a more efficient (and faster) device.
Here are the posts supporting “swap” :
http://www.mod2xtreme.com/showthrea...crease-RAM-using-Swap-File-and-Swap-Partition

http://forum.cyanogenmod.com/topic/44675-how-to-configure-a-sd-ext-on-htc-buzz-wildfire/
While according to “Cyanogenmod” (http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache ) and some member swap doesn’t make any diff .on android devices.
If that’s true and swape is useless then why so many forums going gaga over it on XDA at the first place ???It makes no sense. So bewildering.
Any suggestion ?Any help would be much appreciated.
Thanks.
You should try 256Mb or 512Mb ext2 partition as per your convenience with 0 swap size.
After partitioning your card you need to install an a2sd script and use a2sdgui app to move apps.
Or else you could install link2sd app and i guess that moves apps to ext partition without needing a script.(haven't tried it though)

Swap is used when you run out of RAM space.I dont think we need it on our wildfire.Just select 0 as swap size.create SD partition from recovery,that would be easy as you don't need to be confused between ext2 or ext4.

You've kind of answered your own question with the link you've provided, if you think swap may be worth using, backup your SD card create a swap partition and give it a run for a while, if you think it isnt then backup everything again and create a partition without it. I had swap enabled when I first created a partition but saw no benefit at all.

Moving Applications data to sd-ext slows your phone down.Don’t move “application data” to sd-ext.
I suppose you are using “S2E”,right ?What’s the format of your sd-ext ? ext3 or ext4 ?
Go through this thread :http://forum.xda-developers.com/showthread.php?t=917377

Yes ,your card’s speed depends on the class of your card. An SD card's speed is measured by how quickly information can be read from, or written to, the card.Speed varies with the class of the card…Class 2 (2 megabytes per second), Class 4 (4 megabytes/second),Class 6 (6 megabytes/second) and so on…

It's working great and ext3 should work fine too.
Acually ext4 provides better performance with journalling.
If you use an Old CWM recovery, it will convert it back to ext 3 when you backup/restore.
ext3=ext2+journalling
As ext4 is newer file system,new features have improved the performance and reliability of the filesystem when compared to ext3.
Journaling can be bad for the life of an sd-card (coz you do more writes).If you are not worried about life of the card, and the choice is based on filesystem performance only then ext4>ext3>ext2.
Ext4 can be used with journalling switched off.So "ext4 without journalling" will be best in my opinion.
There is a debate going on over it,check that out :http://forum.xda-developers.com/showthread.php?t=800353

Links2SD with Linux

Hey,
I am using Linux as my primary OS (Arch Linux). I don't have Links2SD installed at the moment, but I'm thinking of installing it. Since I use Linux as my OS anyway, is it necessary to have a FAT partition? Can I just format the whole sdcard to ext3 or ext4?

Why would you format whole memory card as Ext4? BTW Link2sd won't work well if you have partition of more than 2 GB.

So that I will have The whole of my sdcard as internal memory. I basically don't need FAT/NTFS because I don't use Windows. My OS (Arch Linux) can read ext* filesystems too. In fact, all drives on my PC are ext4.

the only problem that I could imagine is that link2sd expects the ext-partition to be the second on the sd-card. but I don't know how link2sd works. I did it manually and just linked /data/app and /data/dalvik-cache to the ext-partition on the sd-card. another good reason to use 2 partitions might be the fact - if I'm not completely wrong - that the first partition is unmounted if you connect it to the pc and activate file transfer mode. if you linked whole /data to this first partition you might run into problems.
You'll still need a fat partition. Or at least two partitions, one for files and one for link2sd.

Hi,
I have upgraded from 2.3.7 to a JB MOD. I prepared my SD card in gparted with a 500mb FAT32 and the rest as EXT4. I have inserted the SD card and 'setting\storage' only sees the in built 150MB EXT and the 500MB FAT32 on the SD Card but no 3GB EXT4 partition. In terminal I ran a2sd install and on the reboot it said 'optimising' apps and I thought it was moving apps. However, when I install apps from the store they are installed on the in built RAM.
Using app2sd I can't move any apps I used to be able to on 2.3.7.
Can someone please advise?
Thanks
Paul

Here is your most likely scenario because it happened to me: If you created your partition on a PC, for some reason it doesn't work properly (well at least in my case). Then the phone doesn't read the SD card properly. What you should do is upgrade clockswork mod recovery on your phone to the most recent version and create the EXT version using the recovery console by booting into recovery.

Hi,
thanks for the reply. I'll see what version I have. It is probably old as it is 15 months since I did the CM 7 install to my phone.

it should be 500mb ext4 and the rest fat 32, also 1gb ext4 is recommended and dont use ClockWorkMod recovery to partition sdcard, use 4ext recovery instead. CWM makes bad partitions

Is there a specific way around?

Hi,
I read the FAT32 should be first and the EXT4 the rest. Is that correct?

I've redone my card (3GB FAT32/500MB EXT4) but my in built memory seems to run out of space for apps quickly. I thought the SD-Card EXT4 partition was supposed to add more space for apps to the phone.
Is this not true?

Hi,
I am using Elk759 JB ROM. I did run the a2sd in terminal after redoing the partitions. It reboots and says optimising apps 1/...79 (whatever number). I can't tell if it has moved anything onto the EXT4 partition of my SD card.
I will boot into a live linux and take a look on that partition.
If it isn't working is there anything I can do?
Thanks
Paul
That seems to have worked as I've installed loads of apps and it hasn't complained about space.
Thanks for all your help.
Paul
