I am just curious what filesystem is in use on the Inspire. I'm assuming EXT3 but I'd really like to have EXT4 like we had on the Captivate. The phone flew even faster with EXT4 than it did on EXT3 and it flew pretty fast on EXT3 as well.
Pretty sure it is ext3. D1ll1gaf's rom has an optional kernel that runs on ext 2. I have not seen ext 4 anywhere.... But who knows.
i wanna say stock it runs EXT3, and i'm pretty sure i've seen rooted roms running EXT4
^^^^^ agreed.
Can someone please, in layman's terms, explain what ext3/4 is? Also, in what scenarios is the CWM with ext4 support needed?

Ext3/4 are different file systems... Our phone is "native" ext3... Ext4 is a little better...(faster/easier to work with?) Im not totaly sure... I know there filing systems but not much difference in performance
But the new nvflash ext4 is so we can make backups with the ext4 kernels that are out (possibly new roms)

Ahhh, makes sense now. I'm glad I didn't flash an ext4 kernel/rom and get it setup the way I want it and try a backup. that would have sucked. awesome, thanks again.
Yeah I believe EXT4 is faster at read/write operations which should provide better performance for our little blazing beasts, and is also the latest of the EXT file system type. Newer is always better, right?
I am noticing that clockwork now has support for both ext3 and ext4. Can someone please explain to me what I would use ext3 or ext4 for. Are any of the new roms compatable with darktremmers app2sd? I used ext3 on my cliq for that reason but on the g2x with all the confusion with internal and external and internal-external sd, I am kind of lost and need a little clarification if someone wouldn't mind. My sd card i use now I have partitioned to ext3 but so far I have had no need for it and was about to remove that partition but if I may need it in the future when I flash a new rom I will just leave it or upgrade it to ext4. Thanks.
I'm not a dev, so forgive my simplistic explanation. Basically EXT4 is a much faster I/O file system. After flashing a kernel that has EXT4 support my I/O scores in Quadrant Advanced shot up and my total score is now over 4000. Before that I could get in the 3700's. So it makes a big difference there.
As for apps2sd I'm honestly not sure.
So basically it's a more efficient file system.

SSo I guess they are not talking about the sd card?? Just the file system. I think I am beginning to understand> Thank you
hi, so i was looking at Leedroid ROM and noticed in the OP it says that you can flash an optional file that will delete everything and format to ext4... this raised a few questions for me since I came from Nexus S.... is the stock sensation formatted in ext3 or 4? Also, don't most of the custom roms upgrade to ext4 or no? and do i have to use this file in the OP of Leedroid's ROM to format the whole system to ext4 before flashing an ext4 rom? I already asked many times in the dev section and nobody would help me out so if someone can help clear this up for me I would appreciate it... thanks!

I wish I could chime in more for you but I do know that when flashing LeeDROID it converts to ext4 so I would guess that it isn't that way to start.
From Terminal Emulator, you can type in "mount" without the quotes and it'll tell you which file system is used in each "mount" (analogous to partition, if you're a windows user).
I just did it on my stock sensation 4G (TMOUS) and it's mostly, if not all, EXT4 already. Unless I'm reading it wrong.
thanks for the response guys!
Just flash in clockwork and it will format your system and data partitions back to ext3. Faster than dealing with nandroid restores.
Useful for reverting from installs using Dragon or Trinity kernels that convert you to ext4.
NOTE: This FORMATS your partitions, you WILL lose all data held on them. Your phone will NOT boot until you install a ROM ZIP file or restore a nandroid backup. YOU HAVE BEEN WARNED.
CREDIT: @paulobrien from Modaco wrote this for the O2x. I just changed the partition names to match our setup. I left his original banner in there as a result. My change amounts to about 4 bytes. If you have issues, please don't bother him, post here.
This is great...I always hesitate trying out updated or experimental kernels because of the amount of time it takes to nandroid....the cm7 kernel has been really good as of late so I've been sticking with that

wow, i never knew that. so if we are using one of your cm7 ext4 kernels and then flash a new nightly/kang we could go back to using the stock cm kernel and wouldn't have to necessarily flash your kernel again?

Yeap... should be no issues.
Is there a difference between this and just wiping, formating system and data, in cwm?

cwm is set up to keep whatever format you have at the time you run it, so if you are on ext4, the format command will format to ext4. It makes sense, you wouldn't want to write an ext4 fs onto a partition with vfat on it, for example. Not automatically anyway. And most users wouldn't know what to tell it to use if it were to give you the option. The forum would be full of "What file system do I use?!?!?"... The usual method is to restore a nandroid backup from stock or a stock file system. This is significantly faster.
It is of somewhat limited usefulness as many kernels/roms don't change the filesystem. However, as I switch around a lot with running tests for the cm guys, my own stuff, etc., it's nice to have a fast way to deal with it.

EDIT: nvm. looked over the files and got my answer.
Works great thanks for putting this together. Will come in handy.

is this utility gonna wipe out all my data (meaning I will have to install all the apps again, setting up my phone again, signing in to google again and stuff) ?

Yes it will wipe.
Upgrading EXT3 to EXT4 will preserve data but downgrading from EXT4 to EXT3 won't.
With cm going ext4 this is priceless.

A nandroid of ext3 is the same thing also I have installed an ext3 rom over ext4 works great

Why do we people want to go back to ext3 when ext4 is much faster and stable than all the other filesystems.
