I have a question, has anyone tried to implement EXT4 on the Evo? I'm coming from a G1 and I know I used to HAVE to have an EXT partition on my sdcard. So now I am wondering because I know there is a performance boost of some sort with it.
I was curious also since even on my Hero, some roms supported the EXT4. I did read, however, that EXT4 didn't really provide much for the use of the phone so nobody really bothered with it and just stuck with EXT3.

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.
What is the largest size you can have for you EXt3 partition, for Android to able to hadle it. I heard 2gb, but I'm guessing it's a good idea to keep sefa and stay below.
Any hard facts on this? I'm about to partition a card in Amon Ra.
Its a guide line 2Gb after that can become unstable my EXT3 1280mb
Thank you!
I'm going for 1700-ish. Could I run into any problems with that?
Can't see any probs its below 2gb
i have partitioned to ext4 with 2gb and i'm on data2sd rom.
everything going smooth...so far!
It was only a few months ago that people were recommending nothing greater than 1gig, due to performance issues...
How the world doth change!
Looking forward to the new 3gb recommendations... Coming next spring in a phone near you!
Hi,
I'm seeing more and more ROMs coming out with EXT4 partitioned system but this is a question that I haven't managed to find the answer to...
I was wondering if it is completely safe to use EXT4 with the Desire HD's hardware due to EXT4 being faster than EXT3?
I know that since Gingerbread Android officially supports EXT4 and that the Nexus S is using it, but the Desire HD is a bit older than Nexus S and I just wanted to be sure that it's hardware and memory chip can take EXT4 pounding with no risk of shortening it's life. Oh, and I mean all this about the internal storage chip of the device, not about creating an EXT4 partition on the SD card.
Anyone?
Thanks
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 know but I believe it would be able to tell what type of Ext partition the sd card has

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.

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.
