[MOD] Data2SD (Enhanced) - I/O Fix

At the suggestion of several users, I am forking the previous thread. I am planning on supporting several ROMs and this is the best course to keep everything organized and provide support.
What is this?
Background:
The speed of the flash memory in the Transformer line of tablets is very poor. This is very apparent when installing or updating applications from the Play Store, copying files over USB, or using an app that caches lots of data like a web browser. The tablet will hiccup and stutter due to the I/O bottleneck. Running Androbench shows random write speeds averaging less than .2MB/sec.
The workaround:
Utilizing a fast, class 10 microSD card, we can move the /data partition to something significantly faster. The /data partition is where apps are installed to and where they store their configuration information and data. By redirecting /data to these fast microSD cards, we eliminate this bottleneck from our devices. With a properly fast card, users have reported a complete elimination of I/O related hiccups and system freezes. I have based my enhancements on the initial work by TweakerL on the Transformer Prime. Credit to fordwolden to porting his work to the Infinity.
The enhancements:
Previous implementations of this mod had the internal data partition mounted to /data2, with the media subfolder (your internal user storage) only available via root apps. There were symlinks set up at /sdcardi, etc, but these still required root permission to access. This is due to permissions on the /data partition and applies to both /data and /data2. Google gets around this by creating a "virtual" sdcard that points to /data/media. I have created a second "virtual" sdcard that points to /data2/media. This mod creates the scenario below:
/data = ext4 partition on microSD (fast)
/data2 = ext4 partition on internal storage (slow)
New changes:
/data/media -> Virtual SD Card Daemon -> /storage/sdcard0
/data2/media -> Virtual SD Card Daemon -> /storage/sdcardi
/sdcardi -> Symlink -> /storage/sdcardi
/mnt/sdcardi -> Symlink -> /storage/sdcardi
/storage/sdcardi is the virtual SD card for the internal storage. You should see all the files you had saved to this space before using data2sd. These files should be accessibly by any standard non-root Android app.
Note to kernel developers: This mod is more than just changes to the kernel. In order for the internal storage to be properly mounted at /storage/sdcardi, I have modded the Virtual SD Card Daemon that comes with Android. The stock binary is /system/bin/sdcard. I made a copy, modified it using a hex editor, called it /system/bin/sdcardi, and included it in my flashable zips. If you wish to make a data2sd version of your kernel, you must include this file in your zip. Additionally, be sure to add the "service sdcardi" line to your init.cardhu.rc that I have in mine.
Installation
Requirements
1) Class 10 microSD, at least 8gb
2) A computer with card reader
3) Partitioning software. Recommended: gparted LiveCD
Instructions
1) Decide how big you want to make the ext4 partition for /data. Remember, this is going to be the space for installing applications AND the /sdcard space that games will use the cache their extra data. Kindle books, Dropbox files, pics from the camera WILL ALL GO HERE. Personally, I decided to make the ext4 partition the whole 64gb of my card.
The ext4 partition has to be partition #2 on the microSD card. Why? This is to give people with large cards the option of creating a FAT32 or NTFS area as partition #1. This allows the card to be read by a Windows or Mac computer using a card reader. I use my tablet as my card reader with the USB cable, so I wasn't worried about this. I used gparted to create a small 8mb unformatted partition as partition #1, then a second 64gb partition to fill the rest of the card. I formatted this second partition in ext4.
2) Format your microSD card - Download Gparted Live CD (http://goo.gl/dJQAu) and use Imgburn (http://goo.gl/33MY9) to write to disc. Boot to Gparted using your CD after setting the CD as the primary boot device in your BIOS. Once in Gparted, create the 2 partitions described above, the first partition is Fat32, the second partition is ext4 or ext2. Set both partitions to type: Primary.
3) Insert microSD into tablet and flash any data2sd kernel for your ROM. (Note: Flashing any ROM will overwrite your data2sd kernel. You will have to re-flash the data2sd kernel if you change ROM or even upgrade your current one) After booting back into Android, you should be greeted with the Setup Wizard. Remember, this is a fresh /data partition, so it's a clean slate. It's a good idea to take a TitaniumBackup** ahead of time. I am experimenting with ways to make the transition more painless.
**Note about taking a TitaniumBackup before switching to data2sd. After the conversion, your internal storage will be mounted to /sdcardi. By default, TitaniumBackup looks for previous backups in /sdcard not in /sdcardi. You have two choices. Copy the TitaniumBackup folder from /sdcardi to /sdcard and restart the app, or change the backup location to /sdcardi/TitaniumBackup in the app preferences. Either of these options should work fine.
Optional: Verify data2sd is working. Pick any method you like:
a) Open a file explorer such as Root Explorer, ES, etc. You should see /sdcard and /sdcardi and be able to browse the files within. /sdcard is your ext4 partion on the microSD while /sdcardi is the internal storage. You should able to copy data between them.
b) Download "Androbench" app from the market and run "micro" sdcard check, if you see 0.4mb/sec or more in random write you're on data2sd.
c) Power off your device, remove your microSD card, then power back on your device. You should received an error message "Encryption unsuccessful". Insert microSD and reboot to fix.
Uninstallation
Don't like data2sd? Just flash a non-data2sd kernel using recovery and when you boot back into Android your /data will be on the internal storage. This could also be accomplished by flashing your ROM on top of itself without wiping.
Troubleshooting
1) Grab the mount-data2sd.zip from the second post.
2) Boot into TWRP and flash the mount-data2sd.zip. This will mount the microSD as /data in recovery. It will allow us to wipe it, format, etc using recovery.
3) Wipe "Internal Storage". This will erase the entire ext4 partition on your microSD.
4) Flash ROM
5) Flash data2sd kernel for ROM
*CAUTION*: If you don't flash mount-data2sd.zip before your wipe, you will be wiping your internal memory.
Download data2SD kernels
These are flashable zips. It will disable journaling on the microSD ext4 partition. You do not have to do this manually! Flash these after flashing the ROM.

Recovery
I made a flashable zip to help the recovery console understand our modification. By default, if you go into recovery and do a factory reset, it is formatting the /data partition on the internal storage. The issue same applies to nandroids. We may be using the second partition of our microSD card for /data, but the recovery does not know this. It will look to the internal /data partition during backup and restores.
This zip does not make any modifications to your tablet or copy any files. It simply updates your recovery mount points. The changes are temporary and are lost during the next reboot. You will need to flash it each time you boot into recovery.
After flashing this zip you will be able to:
1) Wipe data / Factory reset. The /data partition on the microSD will be wiped
2) Backup and restore nandroids. The /data partition on the microSD will be backed up or restored.
3) Choose "Flash zip from internal sdcard" and browse the files on the internal storage
4) Access and flash zips from the microSD storage. Choose "Flash zip from internal sdcard" and notice the !microSD folder at the top. This is a symlink that will kick you over to the microSD storage. This !microSD folder appears on your internal storage after you flash this zip for the first time. It remains unless you delete it. Even so, next time you enter recovery this !microSD symlink will not go anywhere until you flash this zip.
Please report your experience with this.

This one too.

So this is basically flashable on CleanRom 2.3 right? Only thing wrong is that it doesn't show up in windows over USB? I can live with that as long as apps can read it in the Android OS itself.

can I use flash this on cleanrom 2.3 to diasable journalling on my ext4 partition

Use recovery to wipe the /cache partition. Due to the changes in framework-res.apk this may be necessary if you aren't coming from a completely clean install of a ROM.
I just booted to recovery and wiped my microSD /data partition. I also wiped /cache and /system. I installed CleanROM 2.3 and in the same recovery session I flashed the clemsynTF700ver22GPU650VC-data2sd kernel and it booted right up.

May be a stupid question but do you still need TWO primary partitions on the SD card (i.e., first is FAT32 while second is Ext4 and used by the mod)? If this isn't necessary or not possible, should the recovery (i.e., installation) files be placed in internal storage?
Forgot to mention I'm using Windows 7 MTP and CleanROM 2.3

Couldyou make one for blackbean? i tried thecm 1029,but it doesnt boot. Would greatly appreciate it.

Sweet
I just ran every shortcut I could think of:
I used Mini partition tool to reduce reduce my 32 gig fat down to 16 gigs & then created a 16 gig ext4 partition.
Wiped everything in twrp and re flashed Clean 2.3 then the new zip.
All I can say is WOW.

Restored everything. Works great no more stalls and stable so far. Hope it stays this way. Now to focus on battery life.

Glad it's working! I've prepared a little treat for everyone to make our recovery lives a little easier. Need to test a few more things before I post!

I'm running CleanROM 2.3 and ClemsynTF700ver22GPU650VC (awesome combo, btw). If I want to use this MOD, should I need to flash first CleanROM-2.3-data2sd.zip and later ClemsynTF700ver22GPU650VC-data2sd.zip, right? Of course, also, formating my microSD using ext4.

Awesome work here Mistar!!!! Thank you so very much for this!!! Gonna replace my SanDisk 32gb Class 4 card with a SanDisk 64gb Class 10 before I run this on CleanRom. I'm super excited about this mod!!!!!! Thanks a million!!!!!!

[Q]How to mount the 2nd partition of my SDCARD?

I just created a 2nd partition on my 8GB SD card so that i could move apps to it using link2sd...but when i open link2sd and select the file system of my SD card's 2nd partition (ext4) i get an error:
Mount script cannot be created.
mount: No such device.
ext4 may not be supported on your device. Try FAT32 on the second partition.

Other small question : Do I really need to mount the 2nd partition if I just wanna install custom ROMs?

If you are on Stock then maybe FAT32 partition may have worked.. or even otherwise maybe it will work,.. haven't used a FAT32 sd partition since JaggyROM 2.x.x ( obviously my 1st partition is fat32 ) ... My second partition is an ext and it is advisable to have an ext partition cause there are many scripts like int2ext , s2e, etc which work well with an ext partition...
A partition is Not necessary to made in order for other ROMs to work.. They will work just as well without a partition .. only thing is your internal memory will remain to be 150 mb.. Which is the memory allocated in our phone's nand..
NOTE: Sense 4.0a is the only ROM that you necessarily need to have an SD-EXT Partition of at least 1 GB. Otherwise it won't boot.

thanks for helping me..

I partitioned (1GB of memory to fat32) my sdcard with MiniTool Partition Wizard to facilitate to link2sd long back. Now I am unable to recover that memory and merge into a single partition. Do you guys have solution for this?

delete the partition in disk mgmt..

If anyone still have the above issue then just change ur sdcard partition type to ext3. Reboot mobile. Better to use link2sd for this.

Use Other Kernel
The reason for your second partition is not recognized is you may be at Stock Rom and Stock kernel....
Stock kernel do not support ext partitions...
Use ateeq kernel or cranium kernel for ext4 partition support....
Also use Mounts2sd instead of link2sd...!!!!

I used mounts2sd after I created sd card partition(ext3) but this app said partition not mounted; but link2sd recognised n created scripts.

[Q] SD-EXT on SGS4G with CM9?

I'm currently running bhundven's herring CM9 with no kernel modifications and CWM 6. I find that the internal storage for this phone is very low and only holds a small amount of applications, especially since many apps seem to not want to install at all (about 3/4 of the time I try to install things, I get either "Package invalid" or "Insufficient space available", which is extremely annoying and might be a separate problem).
Is there any way that I can get sd-ext to work on this phone with this setup? I'd rather not switch kernels (I'd love to get TWRP recovery but the flashable doesn't work for me and I don't want to switch kernels).

I haven't used it but this app should do the trick.
https://play.google.com/store/apps/details?id=eu.codlab.int2ext
Let me know if it works.

I prefer Mounts2SD, which lets you completely configure things. I was running PACman with cache and dalvik offloaded which worked quite well. And free is a good price.
https://play.google.com/store/apps/details?id=com.spazedog.mounts2sd

That seems like it just switches the internal and external storage, not making an ext partition on the SD card. But can things like this really be done through an app? I thought these things had to be done through init.d or build.prop scripts.
Sent from my SGH-T959V using xda app-developers app

The app creates an init file. Or so it appears. Like I said I don't use it. It seems that raze does and I'd defer to him here. Either his app or the one I linked should work fine.

Thanks (given) to both of you. And any ideas on what else might be causing the invalid packages when downloading from the play store? It happens even though I have much more free app space than I would need (eg. I had 119 MB of free space and a 30 MB app download failed).
EDIT: Just tried using Mounts2SD, but it couldn't find the sd-ext partition. Do I need to create that manually, and how?

Another way is to create ext4 partition (about 1G is usually enough) on you SD card with free MiniTool Partition Wizard and then use Link2SD to link apps/dalvik to this partition. I've been using it like this for a long time and it works fine. There are plenty of guides on the Web how to do that.

I used CWM or TWRP to create the sd-ext partition. You need to create that first somehow... if MiniTool Partition Wizard will do it without wiping the sdcard, that's better than recovery though.
My method was boot to recovery, mount sdcard, copy everything to computer HD, unmount sdcard, partition sdcard with 2 GB sd-ext (because I wanted lots of space, but I'd probably cut it down to 1 GB next time), mount sdcard, copy everything back from computer HD, unmount sdcard, reboot to system. Then launch Mounts2SD, pick what format you want the sd-ext in (FAT or ext2 are the fastest, but you can take ext3 or ext4 if you're not going to just disable the safety features) and what stuff you want moved over.
Edit: Just found this link, which I haven't used but which explains how to do the sd-ext with MiniTool... apparently MiniTool DOES still wipe the partitions though, so you may as well just use CWM/TWRP and make your life easier.

MiniTool will wipe the sd card to create the new partition as well. I wish there was a way to do it without wiping the card but there is not. So back that stuff up first.

Yes, but our herring kernel does not support EXT4 partition, I tried it myself
and it didn't work. I had to create EXT3 which is supported by almost all kernels.

Eh, my results varied. Worked fine for me with ext4. And worked fine for my wife as well.

The OP says he's running CM9. That's what I'm running but I use Proton kernel as CM9 kernel has a video bug, and ext4 partition works just fine for me. Strange if Bryan really removed ext4 support, it's just a line in the config file.

Successfully made the partitions last night but my phone won't mount the SD card anymore. Was trying ext3, I'll try ext2 and ext4.
EDIT: Fixed the problem, changed my partition to ext2 and set both partitions to "Primary" (not sure which one did the trick).

Make sure that you make the first partition Primary/FAT32. This will be your normal SD card. Just take about 1GB of space from it at the end. Then make second partition Primary/ext4 with size to the end of the card. You can try ext2/3 but I don't think it is really necessary.

MiniTool will NOT wipe your partition if you do it right.
dsexton had a guide posted on how to do it.

Is it worth making a swap partition? If I remember correctly it significantly degrades the life of the SD card (and microSD's are delicate as it is), and I don't know if it would significantly increase performance.

There are two ways to do this. 1. If you have a recovery boot loader installed in your phone, you can simply log into your recovery and select advanced and then fix permissions. Once done reboot the phone. All partitions will have their flags set back to read write execute. The other way would be what you did, redo all the partitions again. The last one only works in Linux. I'm not a Windows user so I couldn't help there.
If your a Linux user and not sure how to take ownership of a hard drive or removable drives, let me know and I'll explain it in the next post.

[Q] Problem with Link2sd after resizing ext2partition

Hi all...
Im having problem with Link2sd after resizing the second partition.
What I had done:
Before resizing the partition I copied all the files from ext partition to my desktop
I resized the partition to a smaller one, from 4.5 gb to 3.5.
The total filesize in this partition was under 2 gig.
Using minipartition tool I deleted the ext partition.
Resized my existing fat partition to 4 gb and created ext partition with rest of the space
Ext partition was created as primary.
Now I copied back all the files from desktop to sd card.
But everytime I start with my sdcard, Samsung logo keeps showing after boit sound.
I waited for 5 minutes but nothing happnd.
I started without sdcard. And tried recreating mount script.But the same problem.
How to overcome this problem. Do I need to start from the beginning? ?
My device Samsung Galaxy Fame 6812.
Running jb 4.1 Stock ROM definitely Rooted.

Hi all...
Im having problem with Link2sd after resizing the second partition.
What I had done:
Before resizing the partition I copied all the files from ext partition to my desktop
I resized the partition to a smaller one, from 4.5 gb to 3.5.
The total filesize in this partition was under 2 gig.
Using minipartition tool I deleted the ext partition.
Resized my existing fat partition to 4 gb and created ext partition with rest of the space
Ext partition was created as primary.
Now I copied back all the files from desktop to sd card.

The operation to link storage to ext partition is scripted. Ext4 partition has to be formatted once after installing the script to work properly. Link2SD performs this when setting up. You can try formatting the SD-Ext partition using your custom recovery but i suppose you will have to set up the ext partition again usning Link2SD

Yes, I copied the files back to ext partition after formatting the partition.
Do I need to start from the scratch?

Did you Format it using the custom recovery?

No custom recovery, running with stock recovery. I had no problem when I first started link2sd with no apos linked.
I formatted the ext partition from mini partition tool

Seems as you need to set up the partition via Link2SD again
