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.

Ok I'm currently running JACxHero 1.1 but I'm considering downgrading and I wanna know which is the best ROM to use I've used cyanogen but I'm considering a magic Rom instead but I also wanna put my ext3 partition to work as well as my Linux-swap so any suggestions.

The only Rom Ive found with the old style linux ext partition apps2sd is a modaco premium kitchen rom, and i dont have a premium modaco account. Can someone implement this as a addon zip for the existing rooted froyo rom? Or maybe just make a new rom?
I looked around for documentation on how to implement this my self and haven't found anything useful.
from what ive read,froyo doesnt use this method.there are a couple of threads on using ap2sd on froyo.an easy fix.
i suggest if you want something from modaco premium account,you join up as i did.i doubt anyone here is gonna give you access to what theyve donated to.
the roms we have now are more or less test roms.source has not been released so you will most likely not see anything new until its released.
ne thing i cant believe is the way google implemented apps2sd on froyo. That was the reason for me to revert back to 2.1 CM 5.0.7.1
so +1 to this request. but i guess cyanogen will handle that, if he does a froyo version of cm, when froyo is final!
I liked the linux partition app2sd implementation better as well. Keeps the file-system available for the phone and the fat32 available to mount to a PC or whatever.
Yeah, I'm curious to see why they didn't use ext 2/3/4...
Fat32 app storage sucks. Anything with a widget has to be stored on phone.
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 guess

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!

z4mod can convert all directories, but you are correct that the patcher has limitations.

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!!
just out of curiosity.....which one is the fastest or best??

Too early to tell at this point since both are still under heavy development.
Until samsung releases source for the kernel of the vibrant, any port will we messy and probably betty buggy with a ton of workarounds.

Guys. If you really want this to happen, send me a request and I'll add it to my projects.. I actually started looking into it last night.

sweet, thanks
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.

ive heard that if your battery dies on JFS it will corrupt!
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
i am using Motorola Milestone with MIUI ROM, Overclocked to 1.2GHz, 1GB EXT partition and 300MB Swap partition.
i want to know that how can i usee my swap partition as virtual RAM for my mobile. is there any app for that or any tweak. plz tell.
on milestone swap does NOT work
