Well i'm wondering about a2sd and apps2sd and have a few questions that maybe someone more experienced than me can answer.
1. What is the difference between a2sd and apps2sd? Or are they the same program?
2. How do i get it enabled on my phone, I'm currently switching between WhiteWidow Rom and Aloysious Rom, I have seen the option for it but it is grayed out and I cannot access it.
3. Maybe someone could explain the benefits or using these programs vs not using them.
Thanks in advance for any answers.
I'm sure you could have searched this honestly.
1. Same thing.
2. There should be instructions if it's possible on those roms.
3. Extra space so you can use more apps. They may be slower, I suggest upgrading your card to at least class 4.
sorry wasn't trying to just ask questions without searching for it. I was just trying to find a decent walktrhough. I'll do some more research. Thanks for the response.

In my experience of experimenting with different ROMs, the option (in the "Settings" menu) won't even show up unless the ROM/kernel supports the option. Since you see it and the threads for both of those ROMs say it supports, I will guess that it will remain grayed out until your SD card is set up (partitioned) properly in order to use A2SD. That involves adding an EXT3 partition to the card.
1. No difference...they are the same program (i.e. Darktremor A2SD and Darktremor Apps2SD are the same program).
2. Your SD card has to be partitioned for it (it must contain an EXT2 or EXT3 partition on it. EXT4 doesn't always work if the kernel the rom is using doesn't support it). Your rom must be able to launch apps2sd either directly or via Busybox run-parts. Your rom also must have apps2sd installed (doesn't matter which Apps2sd).
Once you have those, the apps2sd should activate automatically on startup (unless it is being prevented via a flag file (Darktremor) or a property value (DamageControl)).
3. Using apps2sd will free up internal storage by moving your applications to the SD card. Some more advanced apps2sd will also have the option of moving the dalvik-cache to the SD card, freeing more internal storage. This will allow you to run more programs without worrying about running out of internal storage (Android tends to act flaky when there's not enough storage for it to work with).

Thank you guys for the informative responses, now I have a pretty good idea what it does,i would like to give it a try, do I need to back my sd card on my pc before trying? Because it sounds like formatting my card will delete everything, am I right on this?
Yes...back everything up (do a nandroid backup before you backup your SD card...this way you'll make a copy of the nandroid backup). Repartitioning will wipe the data from the card.

additoinal questions
Hello
I have a few additional questions:
1) how can I access the ext2 partion on my sd card in windows through adb?
I want to be able to do this because I want to confirm that the apps are indeed being installed to the sdcard because I notice the internal storage continues to decrease (now this may be due to the apps cache since I am not putting the cache on the sd card...yet)
I would also like to be able to pull apps.
2) I kind of address my next question with the last statement of question 1, can you still pull apps and if so how?
3) I have DConfig on my phone which acts as a gui for app2sd (i think) but when I ran it for the first time I noticed that it did not move any of the apps that came with the rom (all the htc stuff, youtube, facebook, wireless teathering, etc), can these apps be moved and if so how?

1) You really can't. Windows doesn't support ext2-3 partitions. There is software out there that will allow it, but most of it is buggy at best. You can see them if it's mounted in Linux though.
2) Do some googling on this one. I'm inclined not to instruct on such things, as "pulled apps" usually end up floating around torrent sites and screwing honest devs out of their $1.99.
3) I don't believe system apps themselves are generally moved, but I may be wrong on that. (it happens sometimes ) If you move the cache, then their cache will be moved, but that's all.

I use the app Root Explorer, and you can check your ext on there to see what's in it. Also you can move apps around using that app.
I'll ask this here as it seems to be on topic.
The info below was a real help in getting me straightened out on this thanks.

Any idea what I'm doing wrong? I would really like to move some of this to the large SD card and free up the phone for phone stuff.
Also How dose this effect phone memory use if at all? I would like to maximize usable memory for apps to run in as well as allow the phone to run as fast and reliably as possible.
Still looking for an answer. I can not get a2sd working.
With xtr you have to wipe then flash the rom then boot up and set up your phone but don't download any apps....then go back to recovery and flash the rest like stock apps then reboot and let the phone do its thing then back to recovery and then flash a2sd on then reboot and finish setting up your phone....I encountered that too after flashing then flashed the other modules before turning phone on. Does that make sense?
Do everything one at a time with a restart in between, correct?

Did you move ext 2 to ext 3? What allocations did you make? 512 mb for apps? It's been a while since I've done this so it's no longer fresh on my mind.
Why not install one of the Froyo roms? You don't have to format the sd (or do anything special with it) for apps2sd to work. In fact, if your sd is partitioned now, the rom will ask you if you'd like to reformat it at the first boot (which removes the partition for you). The only catch with these roms (or at least KaosFroyo) is you can't move system apps to the sd card (yet) and any app that you use widgets with or apps such as home launchers, texting, etc should be saved in internal memory or you'll have errors each time you usb mount or reboot. I've got a lot of apps installed (many on my internal for the reason listed above) and I'm only at about 35% internal storage. It's a quick rom too.

I am using DamageR Rom and it has DamagedConfig but I can't get any of the apps to my sd. I don't know what to do. I've been looking around for the answer and I just can't figure it out. The creator said to look for it on one of the a2sd threads but I just can't get it right.

Looks like you are on one of my ROMs in which case there is a good write up in the 1st post of both my ROM threads that should get you going
Sent from my ERIS using XDA App
Hey all I'm running CMD 7.1 (RC) on a Nexus One and I've followed the instructions to partition my sd card from here as ext3, installed link2sd, and get this error:
Mount script error
Mount script cannot be created.
mount: mounting/dev/block/
vold/179:2 on /data/sdext2
failed: Device or resource busy
Anyone have a solution for this? I have searched XDA and Google for a solution, a few posts showed up with the same problem, but the person that starts the thread with the same problem ends up not following their own thread, or finds a solution without explaining how.
I am having the exact same problem, Nexus One with CM7 nightly 214. Tried S2E but it kept screwing up and trashing my EXT partition so I wanted to try Link2SD.
Finally got it to work but I can only get EXT3 partition, tried updating using Amon-Ra and MiniTool Partition but neither updated to EXT4.
In Terminal you can check the type of EXT partition by typing: mount | grep sd-ext
Everything I tried kept giving me only an EXT2 partition, I tried converting to EXT4 using MiniTool Partition Manager which reported a successful conversion but when I checked in terminal it reported EXT2. I then used Amon-Ra recovery to convert from EXT2 to EXT3 and now Link2SD works. Lexar 32GB Class 10 SD. Hope this helps.
Possible solution
I might have just found a solution.
Do you guys use any kind of bk2sdext? (automated backup of app/data to sdext partition, which comes with some ROMs built in)
To find out, go to your build.prop file in /system and check, it's one of the last lines, if it says something like bkup2sdext.enable=1, then disable it (switch 1 to 0), save and restart.
After that either go to ClockworkMod Recovery or just unmount your SD card, in order to FORMAT the sd-ext partition again so that it doesn't contain any data (and doesn't get automatically filled back, because bkup2sdext is off now).
This way I was able to mount it finally.
I think it has something to do with the build.prop AND the sd-ext partition having some other data on it before first mounting with link2sd.
Cheers.
download titanium backup press menu select batch operation scroll down till u see move all user apps to sd(if supported) and also make sure that you have checked allow application moving(settings->applications)

Hi!
Partitioned my 32GB sdcard, and put CM10.2 on it, but when I check it I have only about 400mb of space or something like that. I had the same amount of space on a 4GB sdcard I used before. Why am I not able to use up the rest of the GB's?! Can someone tell me how to fix it, I don't know if I'm partitioning wrong or doing something wrong, but I want to be able to have lots of extra space for music, apps, etc. Please help! Thanks!!!
I believe you used a low level utility like dd or similar to flash an image onto a partition.
You need to run fsck on that partition, then run resize2fs to expand the ext2/3/4 partition.
Let's say your partition is /dev/block/mmcblk1p1
You would do (in a terminal):
adb reboot recovery
adb shell
# umount /dev/block/mmcblk1p1
# e2fsck /dev/block/mmcblk1p1
# resize2fs /dev/block/mmcblk1p1
After that, your partition will get expanded to whatever size you made it.
It takes a while so be patient. The larger the partition, the longer it will take.

if you got a prebaked image of a bootable cm card from somewhere, then it usually has 4 partitions on it that were set to the sizes the author of the card specified.
/boot
/system
/data
/sdcard
You would need to put the card in a PC, and use a disk partitioning utility to resize the partitions
some of the images include additional flash files that you install to expand the card's partitions for you. (succulent's), but
you have to do it as you install for the first time.
I prefer to build the card empty first, and load the boot files and zips manually.
linux tools like gparted, Parted Magic , booting from a live USB or CD work pretty well.
Windows based ones like Easus Partition master, or Paragon, not so good.
Mini Tool partition wizard (windows/free) sometimes works
this looks to be a decent write up

The write-up is also posted on XDA at http://forum.xda-developers.com/showthread.php?t=2098419. It was written back in the days of CM10.1, so to use it for CM10.2 or CM11:
Obtain the boot files: MLO, u-boot.bin, and flashing_boot.img -- as well as the files boot.img and recovery.img, from the /boot partition of the pre-made SD CM image. Make sure that MLO is the first file to copy to the freshly made /boot partition.
Substitute in the appropriate ROM and Gapps zip files corresponding to the particular CM build of interest.
Hi.
I was using my S2 i9100 as everyday but after a restart both the internal and external SD storage dissapeared and I only have available the internal (apps) storage.
After googling a bit I tried the following commands in the terminal:
su
echo mkdir /storage/sdcard0 > /data/local/userinit,sh
chmod 700 /data/local/userinit,sh
exit
exit
Going into settings>storage after doing this allows me to briefly see the missing devices (calculating disk use) but then they quickly dissapear again, after a couple of seconds.
I booted into recovery and there I can see every folder and file in both devices so it's not a data corruption issue.
I fear flashing a new CM version if that means a wipe of my data folder, because I have some important app data I don't want to lose.
Any way to fix this or at least temporarily mount the devices so I can backup my data with titaniumbackup?
CM version is 11.0-InstallerXNPQ32P
Thanks for your help

HEY GUYS!
Today I am going to explain how to Increase Internal memory or link app data to secondary storage of sdcard.
Before getting into the process
REQUIREMENTS:good:
1)Rooted device
2)sdcard with parted as FAT32 and EXT2 or EXT3
3)Link2sd APP
4)Root Explorer APP
5)patience and a little knowledge in android
Your Android device should be rooted and sdcard should be parted as FAT32 and EXT2 or EXT3.
Now install Link2sd app and and open it you get popup that to select secondary sdcard format you have to select EXT2 or EXT3 which you have created.Then you will get a message mount scripts created then reboot the device.
After reboot install Root Explorer app and open it and press mount R/W at top and give root permissions
now,it will look like mount R/O
go to /data
you will see folders app,app-private,dalvik-cache
move them to /data/sdext2
after moving completes select one of the folder
and long press it or at bottom right side of the page press that dotted button then a big options list opens now press link to this folder
Now,go to /data and press create link
you notice folder linked
repeat this for app-private,dalvik-cache.
Let's create link for data of apps for that create folder in /data/sdext2 and name it data
select a file from /data/data and move it to /data/sdext2/data and create link where you brought the file
But be carefull do not move superuser data so that superuser will forcestop due to lack of data and you need to reboot to get back superuser function back
If everything was done correctly then your internal memory will increase after rebooting device:laugh:.
There are so many forums based on this method in xda but i made some changes in here . Be carefull I doesnt take any responsibility caused to your device.
THIS WAS MY FIRST THREAD SO THERE MAY BE MISTAKES IN SCRIPT SORRY FOR THAT
Sorry guys?
In the above post:good: we have learned how to mount secondary sd-card partition and link data files.
But the main point is that the method works upto ANDROID 5.1.1 LOLLIPOP only this method is not working with ANDROID 6.0 MARSHMALLOW.
In android 6.0 system itself asks us to set sd-card as internal or portable.
*portable:sd-card will mounted for just storage for photos,music not for apps data but you can connect to pc and send files in mtp mode and no need to be formated to mount.
*internal:sd-card will be mounted for apps data but not shown in mtp mode to transfer files from pc and aslo need to be formated for mounting if we insert partitioned sd-card then the partition will be erased.
*If we insert a partitioned sd-card the system says as corrupted sd-card but after reboot the primary,secondry sd-card partitions will be mounted as portable sd-cards and if you select for internal type the partition will be erased.
After all this Link2sd cant mount the secondary partition.
Solution is in the post #3
FINALLY HERE IS THE SOLUTION FOR MARSHMALLOW
1)Download "Apps2SD" free app or pro app from playstore.
2)Open the app and grant root access for it.
3)Now in the menu press "Partition Tool (Adoptable)" and create partitions of sdcard as you wish and then reboot and again from app menu press "Link apps to SD card" and choose the secondary sd-card partition you have created.
4)Then finally the mount script has been created for sd-card.
5)Now you can access link2sd also without creating mount script again
PRESS THUMBS-UP BUTTON IF THIS HELPED
