Alright, I'm running darktremor a2sd with an ext4 partition in decks 1.2 and loving it. I'm thinking about messing with synergy and know that I would need an ext3 not ext4 partition to run dta2sd. In amon ra you can upgrade from ext2 to ext3 and 3 to 4. Is there a way to "downgrade" to ext3 without wiping and repartitioning?
Thank you in advance for any help.
Not in any recovery that we have available. I thought I read at one point that you can set SD partitions in Linux, but I don't know if you downgrade in that either.
ok, thanks, thats kind of what i thought.
another question for you or those in the know......i'm pretty sure since i converted my ext3 to ext4 and resetup dta2sd that my temperatures have been getting considerably hotter than before. people suggest that that ext4 isn't the best for the life of an sd card because of extra writing going on.....could this extra work also be contributing to higher temps?
I've got my SD partitioned to ext4 on CM7 with s2e and I've haven't noticed a temperature change, but it sounds possible.

Beginner here that's catching on fast but still a little wet behind the ears. I want to partition my sd card does this sound about right I'm %100 percent on the ext2 size I want it 1024mb I have a 32gig sd so space isn't an issue. What I'm not sure about is what size I should make the swap right now I'm thinking 160mb. Please help I'm planning on doing this tonight before I gotta wake up for work. Any help would be greatly appreciated.
Also what is ext2 to ext3 option is it needed what does it do?
Also I'm running cm6.1 stable
using ra-recovery
I run a 64mb swapfile and 1.5gb ext3 partition. Personally speaking I would not go past 512mb on swap. Really even 64mb is overkill imho as our evos don't really use it much if at all.
As far as ext2 vs 3 its personal choice. Ext3 adds journaling extensions and ups the file size limit.
Thanks for the quick advice you the man!
How the hell did you get it to a2sd to work? I've tried all methods I can find in the forum, but still installs to internal memory.
The developers thread really helped me out.

Yeah I tried that twice. I am loading stored apks, from my computer, does this only work when downloading from the market or what? I've tried every method I could find in this forum, with no luck.
To load apks from your sd card you must go to menu/settings/applications/ and make sure unknown sources is checked.
Also you should be running the latest version of a2sd for everything to work properly. I run myns warm 2.2 rl4 and while it is a fine rom, it is missing the latest a2sd and busybox.
After you have flashed the latest a2sd zip, you should move ALL apps to INTERNAL memory and THEN go to your android terminal and
/su
a2sd reinstall
I have had a look on the forums and I cannot find how to do what I want, sorry if it is a noobish question.
I've a GSM HTC desire on orange (UK), running cyanogenMod 6.1.1. The recovery is clockworkmod 2.5.0.7 and the bootloader is HBOOT-0.93.0001 (alpharev)
I am trying to install RCMix S v2.0 Evolutionary Sense. It seems it requires s-off to do this easily and I also need to have my SD card (16Gig) partitioned with 1Gig of ext3. The current size of the ext3 partition is 0.75Gig (I know it's a silly size I chose originally). Once this is done I should be able to load the correct bootloader for the Rom and then flash the Rom itself.
I have just flashed my phone using alpharev 1.8 to load a bootloader that gives me s-off.
I wanted to resize my ext3 partition to 1Gig, I tried using minitool partition wizard (which I used the first time) but it won't let me resize the ext partition even after making room by shrinking the fat32 partition.
I am wondering if there is a way to do this without formatting the SD card. My worry is if my phone won't boot if I format the card to resize the partition because as I understand it some system data is on the SD card. Am I worrying about nothing?
Backup your sd card then use rom manager to create your ext partition size. No matter what when resizing you have to format.
Swyped...
GParted will also do it.
Might as well convert to Ext4 while you are at it.
I also couldnt find a way to resize the ext3 partition in windows.
So i made a full nandroid backup (incl SD-EXT) in recovery, deleted old ext3 partition and created a bigger new one. Then just restored the SD-EXT backup from recovery.
Worked well and no data lost
Edit: Is there an advantage from ext3 to ext4? I´m using Insertcoin A2SD V49
I think I will do a nandroid back up and just reformat the card how I did the first time.
777ace My desire is PVT-1 S-off. Also you've got the rom I am trying to install. So I think I'll flash the 0.93/CM7 Hboot that you have.
What are the advantages to using Ext4 rather than Ext3. I assume Ext4 is what you use? Did you need to flash a new radio or did you just do it by choice?
Ext4 is just the evolution of Ext3, and is supposedly more reliable and performs better. I upgraded to 4, because I read alot of people recommending this for many of the new ROMs coming out...a bit of research and the move made sense.
You should already have 0.93 HBoot, if you want to use RCMix (or most of the more recent ROMs). After that, pushing the CM7.img thru something like Android Flasher is easy as.
I flashed the radio back when I was on LeeDroid 2.3f and have kept it since. If you want to upgrade, you can also push the radio.img with Android Flasher.
This http://gavinroy.com/initial-ext3-vs-ext4-results should put things into perspective.
I have tried to find information on this, and I'm struggling.
What file system does the evo use by default? I know it's EXT2 and fat32 for camera card, but the main partitions I do not know. Yaffs?
I've heard things about Yaffs2+EXT2 (refered to as godmode), using EXT2, using Yaffs, and using EXT4, with or without journaling. I want to make my file system faster. I keep finding very diluted information that never gives the whole picture. How does yaffs2+EXT2 work? How do the different options perform relative to eachother?
I'm guessing nobody is going to answer... got pushed a couple pages back on the forum
I'll tell you what I know, which is limited. the ext2/3/4 are used for storing apps/cache on the sdcard. It is separate from the fat32 partition which is where everything else on the sdcard is stored, ie pics/roms/backups... Having an ext partition setup will not automatically speed up your phone. You must use a sdcard that is class 6 or higher to give you the speed you desire. The ext2 partition is used with godmode i believe. I had better results from the non-godmode synergy, so I didn't bother learning everything that I should have. Ext3 is what is primarily used for DTA2SD, which I have been using for 2 or 3 years now. I have yet to see a rom that uses ext4. The only thing I have seen about it, is the recommendation to stay away.
Not sure about YAFFS, you could always google it though.
Thanks, this was helpful.
Appreciate the comments.
I am running ext4 from a a script on my gtab. Can i run ext4 with this script on the evo?
I read somewhere that the evo cannot use ext 4. Check out synergy god mode, it has some weird hybrid file system if I remember correctly.
EVO default is YAFFS2. Godmode is YAFFS2 + EXT2. EXT2 and file sytem and YAFFS2 as wear leveler layer.
Read a little on Linux history, I know that EXT2,3, and 4 are newer than any YAFFS, with EXT4 being the new standard for now. Basically all of the new phones use EXT4 now, that was made the new standard or something of the sort with Gingerbread.

Might be a stupid question.
Well here's the deal i partitioned my sd card to ext4 (i think i'm not sure how i can find it out if it is ext3 or ext4). I was reading that ext2 was faster and quite better than ext3 or ext4 so i was thinking is there any easy way to deconvert from ext4 to ext2. What is the best way to do this preferably without loosing any data from sd card or the partition?
And how can i find out easily what partition my sdcard is ext3 or ext4?
Im not sure where you get that information but devs wouldn't recommend EXT4 partition if its gonna slowdown the performance of their roms.
I bet gparted can tell what type of ext partition you have and I bet there are other ways to find out... You can flash 4Ext Recovery and that will show you those information as well.

4ext recovery converts partitions but only between ext3 and ext4 without data loss. Al though I am scratching my head, where did you read that ext2 is faster than others?
Ext4 has more features than Ext3 and Ext2, main advantage is journaling which gives improved performance and reliability. The only downside with ext4(also ext3) is that the SD Card wears out faster since it can perform more read/write activities. If I was you I would keep things the way they are.

I saw something about it on androidforums.com and somewhere else i can't remember where.
There few people said that after going from ext2 to ext3-4 the rom that they had became a little laggy and it said also that some kernel dev said to use ext2 rather than ext3-4.
Also said the same thing you deadlyboss01 said about the sd card wearing out sooner.
Is it maybe silly to use ext2 if i already have ext4?
And if i set up 4ext recovery can i restore nand backups from cwm?

I believe it can since 4ext recovery is based on cwm but better post the question on the 4ext thread to get an accurate answer. Sorry im not that sure.
via xda app
It seem that you are quite adamant. Have you personally experienced these lags?Also, I had the impression that kernel devs focused more on ext3/ext4. Nevermind, CWM is indeed compatible with 4ext recovery as Stankyou said.
No i personally have not had these lags but it seems that i'm just going to stick to 4ext and try to flash the 4ext recovery and check that out
Thanks to this thread(and others), i got some balls and knowledge. And i've installed, 4eXT Touch Recovery and then converted my ext3 partition to ext4 with 4eXT, way to easy. Needless to say, that Recovery is awesome! Thanks People! !
I also read this on ext2 being better and was confused, some guy had a htc incredible s and experienced lag with ext4 and not on ext2.
Well, i also see alot of devs using ext4 and now this thread... think this is quite simple, Use ext4 if the rom supports it.
Is there any major difference between an ext3 partition on one's sd card and an ext4 one? Is there any point in converting an ext3 to and ext4 (using 4ext recovery)?
Also, if I did this, can I restore a backup made from my old ext3 partition into an ext4?
Edit: This has been covered before, I only just spotted the suggested existing threads feature. Damned if I can find the way to delete this thread though.
