[Q] About filesystem conversion - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
I was just thinking...we all have problems in our phones because of the RFS filesystem, couldn't we with a kernel supporting ext3 and a custom recovery, format all phone partitions in ext3 and then flash a custom rom?Instead of having just a partial conversion of the filesystem we'd have the full filesystem in ext3 resulting in a even bigger performance to our phone?
If this is already done, sorry i didn't knew.

I agree with your question. I wondered too, whether it's possible, but haven't seen any answer/information about this issue. Maybe someone of the devs could clarify this? It would be great!!

Let's hope that our dev machines say something about this

Converting /system and /data over to ext

Is there any way to convert these two filesystems to ext2 or above?
I'm looking for an I/O boost in quadrant as well as looking forward to seeing how this will affect daily usage performance and speed.
Didn't find any threads on the matter.
Would appreciate if someone helped me out here
Thanks.
Well, apps2sdext hard links the data and dalvik cache folders to an ext partition on your sdcard
But if I am not mistaken the internal NAND flash is faster than my SD card.
I've observed that such a thing is possible on phones like the Samsung Galaxy Spica, where the filesystem on the /data and /system partitions can be converted to EXT to get a huge boost in speed and stability.

[Q] 4EXTRecovery Question

Hi,
Sorry guys need to ask. I have checked out the forums and i think this hasnt been asked before. Again sincere apologies if it has.
I am using an incredible s, just got it s-off and rooted and was about to flash Android Revolution HD from my sd card.
As part of the process I had to flash 4XT recovery which I have.
I just need to check, whenever I go into recovery is says the following :
"You currently have some EXT3 partitions ->If you wipe/format. I will use EXT3 You can however explicitly wipe EXT4 by visiting the "ext" <-> ext menu
If you are on an EXT4 Rom, you may want to conver the partitions to EXT4. Open the ext3 <-> ext4 menu to do that"
I know I will have to flash a wipe file before flashing the new rom.
Do I need to do anything to address the details above or can I just contiune as normal?
Sorry my first time tinkering with an Android phone.
THanks
You should wipe and convert all partitions to EXT4 before flashing the new ROM.

Thanks, the wipe will be done through flashing the file "Android_Revolution_HD_Super_Wipe" am I corrent?
Also, how do I convert the partitions? I read some threads where people bricked their phones by playing around with the Partitions on the SD card. Not sure if this would mess me up as well
Any insight?
You don't have to wipe or convert! Just flash super_wipe.zip you mentioned, it will do everything for you. It cannot be easier
Thanks, it worked perfectly, running Android Revolution HS with the sense 3.0 all in one patch

Having problems with ext3 for months now... help :(

Hey xda!
I keep losing my ext3 partition with all my apps every few boots.
It actually usually happens after I have trouble installing/uninstalling apps, which send my phone into softboot mania. A hard reboot usually fixes the app install problem, but every so often unmounts the ext3, which I then have to reïnstall.
Over the past months I've been moving dalvik around, flashing new ROMs, full wipes all the time, checking ext3 for errors, using different software to format re-partition,... The problem is that these issues are non-persistent and so very hard to check if it's fixed. So every time I have to reboot I'll clench my heart and full on rage when I lose ext again
So today after partitioning my SD card again and doing a full wipe, only to lose my ext3 again after hours of setting my phone back up it dawned on me... could this be my recovery??
I'm on CWM 5.0.2.0
It served me well for like a year until I got into the whole A2SD thing...
Problem is I wanna go back to AmonRA now (think that was my first recovery) but Mod Manager won't let me anymore. And I don't have adb anymore, nor the knowledge of how I rooted and did all of that stuff 2 years ago (scatterbrain).
So... Any thoughts on this, is my recovery the issue here? And can I flash AmonRA without having to go through adb and all that?
tl;dr
My ext3 is ****ed (sporadically), I THINK recovery is to blame. I suck at adb, how to flash AmonRA?
Any help will be greatly appreciated!
Yeah...quit using CW around version 3 due to the exact same BS...I found I had to actually repartion the whole SD card several times and even lost my backups once...
AmonRA was good but the newest greatest and most amazing recovery inho is 4EXT! http://forum.xda-developers.com/showthread.php?t=1291970 it has been the best recovery I have used bar none and the developer is awesome with support if needed!
Thanks for responding so quick, you did not lie about the awesomeness of 4ext!
I'm having a blast tinkering with the recovery control settings
Since we're in the same boat, maybe you can be of advice.. Would upgrading to ext4 do me any good? Any upsides to it?
When I got into A2SD, ext4 was too new and considered to be "DANGEROUS EXPERIMENTS" xD
EXT4 is the stock filesystem for all new Android phones.

Oh ok, so it would be ridiculous for me to get it now, thanks for clarifying
For the record, this issue has (as it seems for now) been resolved by flashing AmonRA and wiping -> repartitioning the card with that.
While AmonRA was great I found many advanced features in 4EXT. For instance you can go from ext3 to ext4 and back again with just the push of a button. EXT4 is a more efficient file system and most ROM's nowadays should support it...if not just switch back to ext3. Also 4ext will check for filesystem errors on your SD card and also check partition alignment. If you use 4ext to partition it will ensure proper partition alignment which the other recoveries don't do....
While I was impressed with ext4 features and all, I tend to go with stability over advanced features. Which is why I'm on Amon_RA's recovery, and also why I'm on an OTA build ROM, so ext4 support is ruled out for me. I want my phone just to have all the functionality I need, and have maximum reliability so I can always depend on it.
In the ext4 thread there's a good example of why I will mostly choose stability over extended functionality

I confirm 4EXT is the best recovery (using it for few months now without any pbs) and ext4 partitions are reliable now! Don't hesitate.

Need help for S5839i ext4

Hello,
I'm a little lost, I looked at the forum to help me, but I still can not do.
I would like to run the extension ext4 on my s5839i
At first I tried ext4 with Razodroid (but if you have another ROM do not hesitate to tell me)
as I could not do it I turned on original firmware and flash a kernel that accept ext4. But no interesting results.
So, here I am really lost....
My questions:
- What recovery do you recommend?
- How to run my Ext4 on my ACE?
Thank you very much for your help, because after trying a lot of TUTO, kernel, ROM, script (cronmod) I still do not have conclusive results. :silly:

For me I use cwm5.It's up to you.
For EXT4 flash this Format-All-Ext4.zip by Rafael.Baugis.It will reformat all partitions to ext4 except sd-ext.Make sure that you have your custom rom in sdcard for reflashing and that you did a backup of your data.

hi man. Thanks for your help.
But it dosent't work, my ACE block in the kernel animation.
Ps: Is there a possibility to use the ext4 with a original firmwares?
Thanks

[Q] F2FS Confusion

I finally decided to take the risk of converting to the F2FS file system. I'm a little confused on just how far I should go with it. The readily available guides only mention changing the cache and data partitions. I have made this jump, and I absolutely notice a difference. My question is that there is also an option to format the system partition to F2FS, but I can't find anything concrete on its benefits. Honestly I can't find much of anything about it. Does anyone have any experience with F2FS system partition conversion?
You don't write anything to system partition as it's pure read-only. F2FS would make zero difference. It's just a hassle making ROMs work with /system under F2FS.

Thanks, that makes complete sense to me. So I'm done then? Just go with what I have?

Don't format the system partition to F2FS. There is zero benefit from this since, as stated above, it is mounted as R/O at boot time, diminishing any positive effect F2FS may have the phone's performance (slower reads, faster writes, theoretically.) Anyways, most ROMs format /system to ext4 when being flashed, so there's that too. Just go with what you have, which is ext4.
