which one is better in sgs i9000¿?
Why not ext2?
Doc's Rom DamianGTO kernel
somebody says that ext2 it's not reliable so... i didn't put it.
undoubtedly ext4.
I've never lost any data using ext2, that said, I'm currently using jfs all, with system reiserfs. Phone flies.
Insanity 8
now i'm using fugumod all with jfs also because in the fugumod post somebody told that it was the best but i don't see anything different from ext4
Wrong section and old debate and since google used ext4 for Nexus S most of the dev use it for Galaxy S. Because who know better than google what is best or not
yeah, but testing the filesystem with some apps the jfs beats ext4 on galaxy s i9000. at least it's what i read in another post.
I've used ext 4 a lot before and currently am on fugumod with JFS and I can honestly say my phone never felt faster!
I'm only a day with it though, but haven't had any problems so far. But I don't think it's as unreliable as ppl make it to be, I believe is used without trouble in linux as well.
Now that a lot of FS have been added for us to check out, I think we need a discussion on the best one to use.
This should be in q&a and not in development.

I did a test and the results show that JFS is better in I/O.
I wonder why so many people are so fond of EXT4.
A combo like reiserfs on system and rest on jfs seems like the fastest way to go.

Strange Problem with JFS/ReiserFS
In Development Thread there is mentioned, that there is a problem with the language/timezone settings on some systems, but these settings are not the only one affected.
also ringtone/message tone "usb debugging" and more settings seem not to be loaded correctly after reboot, when i convert all partitions to JFS or ReiserFS.
there's no problem with ext4 here...
there is also no problem if i just convert /dbdata to JFS or ReiserFS, but if i convert any other partition my settings are gone again.
where is the diffrence between the ext4 and the jfs/reiserfs driver here? shouldn't the fs be transparent to the userspace part of the OS, or are JFS/ReiserFS partitions mounted too late at boottime?
pls help, i do not want to stay on ext4 and the default.prop fix for language is not enough for me due other settings are affected as well...
i'm running FuguMod 3.5-ultra on JVB

I met the same issue when using JFS filesysem with the ZSJPK rom.
At last, I surrender myself to EXT4

Dear all experts,
hope i m not waiting everyone's time. it seems that not many have asked this question, so maybe i ask. pls help answer or revert me to a link which can explain this.
Question: whats the difference btw the diff extensions? i know from wiki that ext4 is the successor of ext3 and ext3 is the successor of ext2. so shld we all convert our ext to ext4 for better features?
THANKS in advance!!!
They are all versions of the ext filesystem, evolved over time.
see http://en.wikipedia.org/wiki/Extended_file_system
Your question is moot because going forward (2.2+) apps will be installable on the FAT filesystem so no additional partitioning is needed.
Isn't ext2 supposed to superior to FAT?

Except it is up to the developer to enable that, only one app so far that i own has apps2sd enabled. and FAT32 does not work with root apps, so EXT is still very relevant.
Found this amazing kernel/recovery in the i9000 forums. It gives you the options to install/uninstall different lag fixes via an option in recovery. Examples:
* OCLF: /data stays at rfs, but has an ext2 loop device on top of it
* Voodoo: /data is ext4, all others are kept at rfs
* JFS Voodoo: /data is jfs, all others are still rfs
* No-RFS Standard: /data is rfs+ext2, all other partitions are ext4
* No-RFS Advanced: all partitions are ext4
* No-RFS Advanced JFS: all partitions are jfs
* No-RFS Overkill: turns on all options: everything is ext4+ext2 and /data/data is bound to /dbdata
* No-RFS Overkill JFS: turns on all options: everything is jfs+ext2 and /data/data is bound to /dbdata
I tried it on an old eugene373 froyo rom and everything worked, but the key mapping was all mixed up. Volume reversed and back button mapped to home, but I was still able to install/uninstall the lagfixes with recovery. Source is on the 3rd post here if anyone is interested, but all we really need is the custom CWM ported source is here
I'm not experienced enough with this stuff, so I'm requesting a port and hopping someone else is also interested too.

agreed...that would be great
Yea the Universal Lagfix kernel is hands down my personal favorite. I used it with Eugene's pre-Macnut builds and every lagfix option worked flawlessly. I started a thread and tried to get something going on it with no luck. I would LOVE to see this get ported to the Vibrant so we can maintain our keymapping. Excellent thread/post, hope it gets hooked up!
Don't understand the point of it. Can't you just pick a lagfix and use it? Why you have to sit there and switch between lag fixes all day smh

I notice you say something to this effect in almost every thread you post in.
Multiple options allows ppl the chance to test out the different lagfixes to see which one best suits their needs. Once they find the one the like they are not going to be "switching between multiple lagfixes all day" as you put it. Options are good wouldn't you agree?

I second that. grennis = troll in my book.
Whats best is that these lagfixes are all integrated into an app and sold on market
I myself hate downloading and transferring files to my phone.

Not all of those lagfixes are availble on the vibrant, at least no easily. This would give us an easy way to apply and remove the fixes until you find something you like and since its baked into recovery it would be rom universal, so long as it has EXT and JFS support built in. Not to mention easily fixable if you say flash a rom without disabling a lagfix first, you can always disable it in recovery and not have to worry about an odin restore.

Interesting project indeed, but I think z4mod is more promising since it works with just about any kernel since it's a patch to an existing kernel.

The z4mod online patcher has limitations -- it can only patch ext4 to kernels that support ext4, and it can only convert /data, not other directories (/dbdata, /system, /cache). There are benefits to having ext4 over ext2 and having all the directories converted from RFS.
I would really love to see this tool for the Vibrant!

Sorry, I should clarify that the update.zip package provided only converts /data. I don't know what's involved with converting other directories, but I think it's safe to say the Universal lagfix would be infinitely simpler.
BUMP,
I want to see this option avalable.
especially for the No-RFS overkill!!

Can someone help me to change to EXT4??? How to do that??? Just tried to find out in the forum but i did not figure out....Thankssss
Voodoo lag fix will convert your internal storage into EXT4.
Ow thanks man!!! But, where can i get the voodoo for captivate??? Do you have the link???
Never mind...I was reading in other sites that voodoo replaces the main kernel and it could cause some issue whem the official release from 2.2 comes. I will not trie.
Is there some other way to change to EXT4 or is better to use the OCLF in EXT2???
Any change to the file system (any lag fix) will have to be reverted before you flash any ROMs.
Actually, according to what I've read, OCLF's ext2 loopback may have better results than EXT4.
Yeah man...I heard the samething!!! My friend just tried EXT4 and told me that OCLF gives you more quadrands in the benchmark.

Don't install that one click lag fix, simply install a rom that has the ulf or voodoo lagfix already built in.

ext2 is 17-year-old filesystem technology and is not a safe option, especially for a portable device and with the way Android works.
I could make a car go faster too by removing all its safety features.

It's actually not that big of a deal, since the underlying RFS is journaled. The worst that will happen is you'll lose a few minutes of data if your phone crashes while you're in the middle of doing something.
My problem is...I just tried the Voodoo, but im using 2.2 UCJI6...and i think it does not support the voodoo kernel...i dont know...i tried 2 times and my phone freezed in the boot startup...
So, i went back to OCLF 2.3 and i can tell, my phone is very very fast....also getting 1912 quadrants...I know that could not be real...But the boot is very fast...to open apps is very fast as well...everything is nice so far...
If someone know some way to get EXT4 or EXT3 with UCJI6, please help me...As far as i know JI6 does not support voodoo yet...i found other guys with the same issue like me...
Can someone give me some information how can i change that???

you need to read in the developers section. there is plenty of info about this. there is a kernel that supports it. there is also a ULF kernel that gives you many more options. most of the roms are running it.
If you want to keep to stock then try Cognition 4.1.1. They are basing it from the KB1 leaked release. Note that the KB1 leaked and official is basically the same. It has ClockworkMod built in with support for the Voodoo lagfix. Worked great for me. First rom I had flashed and stuck with.
EDIT: I just realized I bumped a 3 month old post. My thread list was set to sort by subject rather than date.... Sorry.
I noticed that in ext4, after a short time, performance goes down. Converting from ext4 to rfs and again in ext4 improve performance, as if all the files are defragmented.
could be true?
Could anybody create an application that does all this automatically by recovery as a defrag?

Stock XXJVK, Voodoo GB hack Kernel, JQ1 modem
Is UCKH3 going to see a EXT4 lagfix, or is there another way I can do a EXT4 lagfix on my phone? I like to play games on my phone, and the games are very laggy. I love I9000 rom because they run very smooth, but can't get a modem that sounds as loud or as clear as the one in the captivate UCKH3. Can anyone please help. I've been searching xda developers every day in hopes that I will find a way to lagfix KH3. Thanks in advance.
No kernel source = no lagfix
Cog 5 got ext 4 and it had no source.... I admit odds of getting ext 4 is slim with out the source.

KF1 had ext4 support built in to the kernel apparently. No source needed. As far as if the KH3 kernel also supports ext4, what else is needed, or what method designgears used to convert the partitions you could send him a private message and see if he can provide the details. You could even just check out the cog 5 v2 package yourself.
No DesignGear's method was unfinished. Converting to ext broke alot of things. It is possible though, but when coding the kernel with out the source you usually end up braking things in the process.

What was unfinished? The kernel supported ext4 out of the box, he bundled in the required e2fsprogs and he scripted the partition conversion before the firmware gets installed.
There is no way to revert without using heimdall (or odin) since you need to re partition, but functionally, he did the job.
v2 seemed to run fine for me for what it was. What was broken exactly? It didn't seem like a lot was broken.
Alot of small things. Wifi would connect but wouldn't reconnect automatically. I don't remember exactly why I moved away from it. Thing is on my phone worked well enough to be a daily driver but not for alot of people. Thing is it is possible to enable ext4, but with out source you end up braking stuff.

Fair enough. I just wonder how much of it was 2.3.3 to begin with.
So you Guy's mean I can't get ext4 without a kernel? If the uckh3 kernel supports ext4 then there has to be a program out there. I also had cog v2 installed but I never had ext4 on that rom either. I also had voodoo control and never saw an option for lagfix on cog v2.

If you had V2 then you where running in Ext4 format. There was no Voodo lag fix per say, but the filesystem was in ext4 format (exactly what Voodoo lag fix does.)

Just a thought, but couldn't you just flash the kh3 modem to a I9000 rom and therefore have the smoothness that galaxy s roms give but with the loudness of the captivate speaker? I was on apex 8.2 with kh3 modem and everything worked great. Though whenever wifi was on people complained of an Echo effect.
No. you do not mix I897 modems with I9000 kernels or vice versa. It causes problems, like you mentioned the echo, other problems vary including loss of audio completely on calls...

I have had the audio loss as well... a simple switch to speakerphone and back fixed it. Was unaware that was a modem/rom compatibility problem.
Luckily, I only use my Captivate as an Media Player or for WIFI surfing. The KH3 modem over Apex worked great for me. WIFI has been stable, battry life is better than the non-lagfixed I897 Roms of any flavor and speed is noticeably faster as well.
