(Q) Ext4 on latest CM7 Kang Milestone

I finally decide to have a partion on my 8GB SD other than FAT32. So i used the FuFu Minimod to split my SD. First to Ext2 then to Ext3 and then to Ext4.
It all went fine. I have moved some basic apps like Facebook and Igo to the Ext4 partion.
The weird thing that drove me to create this thread is the fact that my phone became a bit slow... unresponsive... and just because the Ext4 with basic apps on it?
Did i miss something or this is normal?
Appreciate all feedbacks.

Try wipe both Cache and Dalvik-Cache

Thanks... but is not the case... and yes i already did that before creating the thead.
Tks

Well then, manually move the app to the sdcard, then move back to the phone.
It should move into the ext4 partition.

They are all in ext4...

I know it is inside ext4. Please try to move to the sdcard and back to the phone again.
I did face this b4

I have done that before you mention... and it looks like its a bit more stable.
One doubt... i notice that all sd-ext\app files are alson in data\app.
Why is that?

Why
Is ext4 faster or what ?
Im kinda noob on this android and stuff things, so i donno.
I can put my apps on SDcard without formatting to ext2, 3 or 4.

Well, now after billions of testing, formating, reflashing... all looks pretty nice now.
@ivanotera: moving apps to sdcard is not the same as moving apps to a second partition where this second partition is journaled - case of ext4.
It means that when you boot your phone, this partition is ready to use and does not need to be "prepared" as the usual fat32 - thats why we see the message after boot up that sd card is being prepared (in fact the OS is checking if the partion is corrupted or not.
Also when moving apps directly to sd card like you are doing, is not good as phone becomes slow, widgets, shortcuts dissapear while booting phone and while phone is connected to pc via usb with sd mounted for access.
With ext4 (using ext4.ko module) OS will think that this second partition is part of the internal storage and all of the above mentioned will not be a problem anymore and you will not get that anoying message that you have not enough space just because you added a couple apps.
Hope this can clarify some important things.

Yeah, got it.
But another question, is ext4 "viewable" by windows ?
Because i have a 32gb card, so i use it as a "pen drive", have some apps so when i format a pc, not at home, i have some apps already, and dont have to download it.
Or in the case of creating a ext4, i partition the sdcard, so i have the "apps" partition and the "windows" partition ?

Help on sd-ext

I partitioned my sd card a while ago while still using stock rom, and it worked fine, I was linking apps to it using Link2sd no problem. Now I have flashed the miracle v4 rom and the partition cannot be mounted by Link2sd, even though there's still 1gb missing from the sd card space. help?

recreate mouting script! until the app recognized it ... first time i upartioned my sd it took me 3 atemps until it worked fine

After formatting sd-ext in CWM, it'll usually be in ext3. Select that when recreating mount scripts and reboot. Works in first attempt for ME

for the details you can take a look at the attachment of this post: http://forum.xda-developers.com/showpost.php?p=27177965&postcount=3

I have the same problem with all roms that i have tried. Given that almost all my apps live on my ext2 partition, this is a big problem when i want to try out new roms. i dont want to have to install 100+ apps again even if i have them backup on titanium.
I want to keep my partition ext2. will recreating my mount script several times over work? or is there something else i should keep in mind?
Does cyanogen mod not support having an ext2 partition?

I updated my galaxy ace from 2.2.1 to gingerbread 2.3.6 then I rooted it and installed cm7.2 before that I made backup of gingerbread stock rom. And when I try to restore back on stock rom, it shows MSG, sd-ext file not found. What was the cause and what's use of that file?

Dual boot Nottachtrix 1.3.1 external sdcard flashable zip

A little leg work is required.
FIRST, NANDROID BACKUP
Second you'll need to format and partition your external sdcard as follows.
Four partitions:
First partition is for normal use formatted to FAT32
THESE PARTITIONS SHOULD BE FORMATTED TO WHATEVER KERNEL YOU PLAN ON USING. FOR EXAMPLE IF YOU ARE GOING TO USE FAUX 1.45 EXT4, FORMAT THE FOLLOWING PARTITIONS AS EXT4. IF YOUR NOT GOING TO USE EXT4 KERNEL FORMAT THE FOLLOWING PARTITIONS AS EXT3! If you're using windows download mini partition tool and set all partitions as primary, not logical and label them appropriately!
Second partition is for /system. Should be 350 MB
Third partition is for /cache. Should be 750 MB
Fourth partition is for /data. Should be 2.3 GB
Now that you have your sdcard partitioned download terminal emulator and run the following command BEFORE you flash the sd rom.
su
mkdir -p /sdcard/Boot/Phone
mkdir -p /sdcard/Boot/SD
cp /dev/block/mmcblk0p11 /sdcard/Boot/Phone/boot.img
Click to expand...
Click to collapse
Reboot and flash Nottachtrix to your sdcard
Once you've booted into Nottachtrix on your sdcard download terminal emulator and run the following command
su
cp /dev/block/mmcblk0p11 /sdcard/Boot/SD/boot.img
Click to expand...
Click to collapse
now download smanager from the play store and run the attached script (created by sendust7 and modified by me) as root with argument 1 to boot back into your phone rom (argument 2 from phone rom to boot back to SD). Rename the script to boot-rom.sh. You'll need smanager in your phone rom to reboot back into your sdrom
I did not develop this rom, only modified to boot from external sd card. Report any bugs/requests here.
A huge thanks to Sendust7 without whom I would have never had any clue on how to even get started and to Nottachtrix for the best Atrix GB rom out there.
Nottachtrix1.3.1.sd-ext.zip
If you're having problems with formatting sdcard go here and show sendust7 some love.
I'm working on an update that will eliminate running any commands. Just partition and flash.

now i'm partioning my sdcard,will report for u soon
i have a question: can i flash anyrom on emmc and it doesn't affect on this rom on sdcard,right? and how can i flash mod to this rom?

I dunno what might be happening. Maybe bad download. I've installed with all faux kernels and no problems here. Sorry but I am not a dev, only modified a few things in the installer to get this to flash to external sd card. I'm uploading a video of the entire process from the point of installing to sdcard. Should have it posted soon.

Mini partition tool for windoze
Sent from my DROID RAZR using Tapatalk 2

I´m going crazy over here: I followed everything in the instruction to the letter (although I used mini partition tool) and every time I got the following message at the end of the install:
Installing Kernel
assert failed:
package_extract_file("customize/ramfix/faux/100/kernel/boot.img", "/cache/boot.img)
After reboot I always land on my phone Rom - no chance to get into SD-Rom...
I guess something went wrong with the partioning...

You should really make a guide for windows on how to partition the SD Card.

If youre using mini partition tool on windoze all partitions should be primary, not logical. The boot img extracts to /cache, then mmcblk0p11 (phone boot partition) and then is deleted from cache. Double check your partitions on sdcard and make sure there all primary

Yes, but since I'm really noobish in the Dual-Boot-business, I also made another mistake: I didn't know that you actually have to name the partitions. After doing that and using gparted, it worked... Kind of... Had a boot loop on first try (faux 1GHz kernel), flashed again and used stock D 00 kernel.
I need further testing

[Q] Internal Storage problem

Hey everyone! I've been googling and searching on for this problem for a few days, but I didn't find any solutions for it. So, here goes, I guess.
I own a LG Optimus 2X, currently on CM10 nightly. It worked like a charm, until I decided to try the official LG 4.0 "update". It's horrible in many ways, so I decided to go back to CM10. I am aware that CM10 uses EXT3 and LG's official rom uses EXT4, so I was careful about all that, but it seems as if I wasn't careful enough.
I flashed back the original Gingerbread ROM with a .KDZ file and then via CWM flashed CM10, but I couldn't access my internal SD card (/sdcard), not even via CWM! The camera says that there is "no external storage available" even though there is, ES file explorer says that the "SD card is empty, unmounted or not present.", and other programs such as torrent clients also bug out. I also can't load any music because of that problem. Plus, in CWM, it says "Error, can't mount /sdcard" nor can I format it sadly.
Is that because I didn't format it correctly back from EXT4 to EXT3 or something? I am really having a hard time here. And it would be nice if someone had a solution for this! Thank you all in advance!

I think you need to format sdcard.

Heh, I think I got that one too. But the question is how? I can't even mount it in the ROM and ClockworkMod Recovery can't mount it either. Is there a way to do this over a flashable rom or via PC (like ADB)?

Use the one in all toolkit @ android development to flash a new CM.
It's a common bug for flashing back to CM from LG ICS.
Follow the tutorial and use the CM addon and choose for change bootloader even if you are already on old one.

[Q] New to SD-ext

Hello, I am new to SD-ext and Link2SD and such things, I googled around a little and found the most suitable solutions for the internal memory shortage of CM10.1 is either Link2SD or INT2EXT+
Now I want to ask, which is better at performance, more stable?
I would have went around experimenting as they say but the problem is that I don't know how to remove either of them, so please tell me that too, so if I didn't like one of them I remove it and try the other.
That's all for now, thanks in advance!

I would suggest int2ext, because effectively it increases the size of your internal storage instead of moving apps to sd. As long as you have a class 10 or better sd, you won't notice any difference in performance.

Unluckily I don't have a class 10 SD right now and I doubt my ability to get one for a while. Currently having a Class 4 16GB SD, what do you think would work best?

You can still use int2ext, but you will get a quite noticeable performance decrease. Just test it! To remove just go to system/etc/init.d, then you can just remove its files.

I actually tried Link2SD (With a EXT4) but it didn't read or create a script. I googled, people said use EXT2, so I just said, since it didn't work, let's try INT2EXT.
I flashed it (without removing Link2SD) and nothing changed...
I, just now, removed Link2SD and restarted: no changed.
What do you advice me to do? ((I think the problem is because this ROM doesn't support EXT4, but I am not sure of course))

Int2ext needs ext 4. After removing link2sd, you should reposition your sd to ext 4. And which Rom you have? Because current ones are all sporting init.d, so they support sdext.

Well, seems I should really change it from EXT4 to 2, I guess that's what I will try.
Thanks everyone so far! :good:

Since you have the latest CM10.1 nightly.. I suggest u try this..
Take a complete back up of your SD card.
Make sure u have uninstalled any apps and removed any scripts related to link2sd and such scripts. (When there's any doubt whether the old scripts would cause any problem, i always prefer wiping the device and freshly installing the rom to avoid any mistakes)
If u do not have any problem flashing the ROM again, i really suggest u to do so and then do the below steps. Definitely should work.
Reboot into recovery mode.
Go to advanced option and select SD partitioning option
Select the partition size as 1024mb and swap size as 0mb.
Proceed with partitioning.
Reboot your device.
Save fixed-int2ext+ for android 4.2..1 by CronicCorey on the root of your SD card..
Boot into recovery again.
Go to mounts and storage option and mount data, system and sd-ext.
Go to install zip from SD card.. Choose zip from SD card.. Select the int2ext+ script.
After installation.. Go to mounts and storage and unmount data and system and format sd-ext.
Now reboot the device and check.. It'll be done.
I have done this many times and it's worked. I use 16gb class 4.. No issues.. Smooth for me..
After installing this script.. Make sure u dont wipe dalvik cache using recovery mode. Your device will get into boot loop.. Use wipe dalvik cache script specifically created for int2ext by croniccorey..
