Is it necessary to move dalvik cache to sd? If it is, what should i do to it with terminal emulator? Or should i delete them in the custom recovery?
Im very active in downloading apps and games and i realized my phone memory is decreasing eventhough my app2sd space is 300+ left.

it isn't necessary but it is reccomended
this option is available in all Rom because it helps to save memory...

if you have a2sd in your rom, acquire root shell '#' in terminal emulator by typing 'su' and pressing enter. then enter the command 'a2sd cachesd' without quotes. reboot phone afterwards.
Thanks... but what if i move it to sd card, my sd card will keep decreasing too right due to the dalvik cache added. What happen if finally my sd card turns to 0mb due to full of dalvik cache saved and moved to sd card?

Hey i have tried do what u said in the terminal emulator im not pretty good with this app so i type app2sd cachesd then i press enter. Then it says permission denied and literally all my apps keep force close and i have to reboot. It tooks a while than the usual then it finally boot up. Then i checked in settings, my phone memory increasing only 2mb?

There is no way you will get to have no space on the EXTx(2,3 or 4) partition. I have moved everything on the SDCard (class 6) and it didn't even get to 100MB used (from 512MB). Anyway, I can't imagine aynbody installing 300-400 apps on the phone.
So in any case I would recommend to put everything on the SDCard (class6 or higher is recommended).
After you flash the A2SD darktremor scripts from whatever custom recovery you have I would recommend to do:
1. adb shell
2. su
3. a2sd cachesdreset -->the phone will reboot
1. and 2. again after reboot
4. a2sd datasd -->the phone will reboot
You should be fine afterwards.

No, and I wouldn't recommend it.
I have a few questions, if you are so nice of answering me, i almost have my target config but i have a few doubts,well i have done all of this:
I did partition from the clockworkmod and do this:
From clockwork to install partition with swap to ceiling and minimum 1024 of ext i moved to sd dtapps2sd-2.7.5.3-beta04-signed.zip in the sd enter recovery (cwm) again to go to advanced unmount system, unmount sd ext and next did install the zip
Next gone to start mobile to put in sd a2sdgui and to install, a2sdgui 0.91
Gone to the terminal and write first su and next a2sd install
Later went to a2sdgui dalvik cache on sd ext,etc.
Then I did a new backup of since I stay the system with clockwork just in case
And finally moved my copy of safety of the sd that tape-worm in my PC to the sd again
Dont now if installing the script from the recovery I have to give him to mount system and to mount sd or mount sdext or not for that in adjustments cyanogen he says to me that I do not have expansion to sorrow say to me a2sdgui that if then also I am interested in knowing ifi have to install a2sd.ext4.update.zip or from the commands spending to ext 3 and then to ext 4 from the commands, since the amon ra is not for the galaxy ace or I believe it (if you know that say to me) and 4extrecovery either.
This way i dont know if my sd turned to ext4 before installing the package, which I did was to give him to the command in terminal him a2sd convert-ext4, but clearly the whole configuration at least those those were linked of system to the sd not works, this way so then I did a restore from last backup done after install the script, other question is why when i wrote in terminal a2sd lowmem-ultimate, the change did but when reboot the phone is a2sd lowmem default? I spent hours reading forums but for the poor galaxy ace,there are not much explications of this process.
Sorry if my english is bad,is not my language
Pd finally Ive found an script that converts sd ext automatically into ext4,but i have other question in post3
jusr sharing my experience..
i'm using Grif cyanogen.
also darktremor a2sd.
my card converted into ext4 partition using my pc. using mini tool partition app which tell your partition format.
i've issue when converting from ext3 to ext4 via dta2sd.. bootloop happened..
basically cwm recovery 4.0.0.9 format my sd-ext card into ext3 not ext4... so i had to do it manually via PC.
last thing... sorry i can't understand the point of your curiosity... pardon me.
thank you. Ive found an script that converts sd ext automatically into ext4 and install a2sd auto as well its name is DT-CM7-2.7.5.2-EXT4-signed.zip. But i think that kernel overclocked cm-7.1-oc-kernel-2.6.35.7-perf-CL562111.zip of my ace not support swap because when i do a2sd check in terminal show this Swap - [ ] Partition not present or no swap support.[*] Swap does not start.
,but in a2sdgui show swap is on, and when change in this app swappines to 75 is still this value,but when reboot the phone back to a2sdgui and show 30 forever in swappines. (otherwise in a2sd check show correctly that sd is en ext4)
Do you know some kernel for s ace and cyanogenmod that support overclock and swap?
Thanks for possible reply.
anyone knows the answer of my question?? xD

see here for oc kernel http://forum.xda-developers.com/showpost.php?p=18285271&postcount=1
I think swap is active by default if you have create it before install a2sd..
First of all, I apologize in advance. I searched through everything and can't find my question. I'm a complete smartphone noob (got my first one a couple days ago--Canada's wireless providers are criminally expensive and I boycotted them as long as I could) and, while I'm reasonably good at technical things overall, I'm totally inexperienced here, with smartphones in general, Android, and it's parent OS Linux.
That out of the way: I have a Samsung Galaxy Ace, with Gingerbread 2.3.4 on it, through the provider Koodo. I am loving this phone, but I'm not entirely sure why certain things didn't work. There were apps I couldn't download due to a lack of space (despite a mostly empty 16GB microSD card), and apps that wouldn't install for other reasons. And always that frighteningly small 158MB system drive staring me in the face. So I decided to try to fix it.
I carefully read every bunch of instructions I could find and understand. Successfully rooted the phone. Installed ClockworkMod Recovery. I repartitioned the SD card with a big ext partition and swap space using CWM. I installed CF-Root-S5830_dtapps2sd-v1.2.zip successfully, and App2SD from the market.
This hasn't helped my free space at all. Nothing seems to be using that new ext partition. My available space did not go up at all...but (of course) my SD card space went down by the size of the new partitions.
I was under the impression there were kernels that could help your phone treat the SD card ext partitions like system space, but I can't figure out where or how for the life of me. Everything has worked, but it hasn't actually done anything.
-NoobGrrl
ur cf-root is not the latest, and I think if u make sd card partition by using cwm, the format will be ext3 not ext4.. so, u should try this step :
1. flash the latest cf-root v37-b82 through cwm from this post http://forum.xda-developers.com/showthread.php?t=1158197
2. partition ur sd card by using minitool partition wizard (google it) and make ext4 format.
3. flash the latest darktremor through cwm (don' forget to mount system n sd card) from this post http://forum.xda-developers.com/showthread.php?t=715116
4. install a2sd gui from market... done..
You probably forgot to move the dalvik cache to sd-ext from A2SDGUI.
To begin with, as you haven't done this before, I recommend you download the app link2sd rather than app2sdgui. Your system will be ext3 from CWM. Select and reboot. Then return to link2sd and you can move apps one by one or by batch installation to your partition by creating a "link". This method gives you finer control over which apps to move. It shows file sizes and how much of the app will be moved. After moving the apps reboot and hey presto - free internal memory.
I also recommend getting an app called DiskUsage to see what is taking up space and a file browser with root functions. I use Root Browser by jrummy16 - free on market.
Sent from a phone with an app.
First of all, thanks for the replies! I like the detailed instructions from musf especially...step-by-step for me is really the best way.
Okay, tried to follow those directions exactly. Minitool Partition Wizard has reformated the little 2GB partition I made on the SD card to ext4. Most recent CF-Root and dtapp2sd zips seemed to install fine. I think I mounted all the drives...I just do it from CWM, yes?
Downloaded A3SDGUI and it gives me an error:
Exiting A3SDGUI
Could not start for one of these reasons:
1. Your device is not rooted (it is, superuser shows access granted to A3SDGUI)
2. A3SD scripts could not be found (if so, no idea why.)
3. No EXT partition found (again, no idea why.)
Edit: Tried Link2SD and it gave an error as well, "Mount script could not be created. No such device."
Okay, so obviously it doesn't see my SD card's partition. So I put it back in my PC and recreated it again. No change at all...
yes from cwm, choose the "mount n storage" menu, then moutn system, then mount sdcard, then instal the darktremor zip file..
That seems to have almost worked...yes, I was mounting the drives after running DT. Duh. (I assumed somehow that DTapp2sd allowed me to set up the drives and I was telling the phone to mount it afterward so it could be used. I didn't realize DTapp2sd just needed to write to the drive.)
Almost. Almost worked.
Now, app2sd actually starts up successfully, no errors. (link2sd still gives the same error.) However, App2SD can't actually move anything. All items remain disabled, even after selecting them.
So then I remember the post above about the dalvik cache. So I go into App2SD and try to move it to the sd-ext folder, and it tells me there is not enough space. I have 124 MB of system memory left right now...and the SD card is mostly empty.
Follow the following instructions and tell me if they work:
(redo the steps even if you have done them already)
1. download cwm5 from the forum and place it into your sd card.
2. make a backup of your sd card and reboot your phone into recovery.
3. flash cwm5 file and reboot the recovery.
4. from the recovery, re-partition your card with a ext partition (you dont need more than 256-512mb. I have 16gb card and mine is only 256mb).
5. select swap if you want it.
6. ~partitioning complete~
7. Connect your phone to your computer with usb wire (while in recovery.)
8. mount usb storage from recovery.
9. copy the cfroot file to your memory card from pc.
10. unmount the usb storage.
11. mount system,sdcard, sd-ext (just to be on safe side) and flash with cfroot.
12. reboot.
13. open a2sdgui.
14. click yes, apps are on sd!, zipalign on boot is on!.
15. set swap if you want it.
16. from dalvik, click on dalvik cache on sd-ext and click move and rebuild.
17. your phone should reboot and you will be done
Notes: Its normal that after flashing a2sd script, your phone restarts a coupe of times so just leave it alone for a moment.
Don't forget to give superuser permission to a2sdgui.
If you still get some error, sty flashing the script again.
If it still doesn't get through, search for the dt a2sd beta 4 script and flash that from recovery. Other steps are the same!
Happy FLASHING
I'm using Clockworkmodace. That's 4, not 5, right?
I can't find a zip for CWM5 that is designated for the galaxy ace...
Here is CWM 5 : http://forum.xda-developers.com/showthread.php?t=1291327
Then , i would recommend you to use cyanogenmod 7.2 RC1 , it is better than a stock ROM
2 mistakes from redlag's instruction (cmiiw) :
first, cwm 5 is for cm7 based rom, dunno what'll happen if used on stock gb.. n second, point 4 can't be used, it'll make ext3 not ext4..
uninstall the link2sd then reflash the dta2sd (mount!) or uninstal the dt then reflash link2sd.. can't use both, they're like fire n water, lol.. u must choose..

I think cwm5 should work and i made it using point 4 and it works perfectly.
p.s. sd-ext are normally ext2, not ext3 or ext4. ext4 is normally used in internal.
EDIT: No it dsn't. Use cwm4. I guess that one has partitioning option too right? O easy way out, flash to ics1.2

Go to recovery, Wipe cache/system/data. (make sure you have made a backup of your data.)
Mount the stuff and flash with http://forum.xda-developers.com/showthread.php?t=1258830
You have a new rom with dt a2sd running within
I'm going to try a different version of dtapp2sd first.
Should the ext and swap partitions be logical or primary?
I'm starting to think my EXT partition is not formatting properly in mini partition tool. Unfortunately CWM uses Ext3 and I'm told it's worse than Ext4 and Ext2 is better than both for an SD card.
Both primary. 1st one should be fat32 and second one should be ext2.
Well, good news and bad news. After some work, reformatting the partitions again, reflashing a new kernel, I finally got it working.
Trouble is, it's not stable. Apps keep crashing, the "Gallery" app only shows a black screen, and it randomly loses access to the FAT32 partition when running, and the SIM card occasionally says "Unrecognized" (forcing me to "restore to factory.")
*sighs*
Flash to the rom i linked you to.
Hello to all from Greece!
In the next days I tend to wipe all data in my phone and install the CM7.2, and I want to install a A2SD script in order to install many apps without problem. I have a class 6 memory card 4GB and I want to help me to make this done with simple instructions.
I know how to partition my card with cwm recovery, but in the past I have failed to install correctly the Darktremor Apps2SD 2.7.5.3 Beta 04 .
Thank you in advance!
I think you can use link2sd. Work with that for some time without any bug.
Download from market, run mount script and chose ext2. If fail to mount rerun script and chose another ext until you get it right. Reboot and it's done.
BTW i always mount the 2nd partition in ext3 or 4.
Thanks for your answer!
I think cwm makes by default ext4

While installing rom people often ask for link2sd or s2e support
As of enabling Dark tremor app2sd is difficult for them....
I did an extensive research and came up successful in using and applying it....
I would like to share it here....
####
Before beginning it is assumed that you have a custom clockwork mod recovery and a custom rom is installed on your device. Alternatively, if you are in a stock firmware/rom and want to partition your sd card please Install Clock Work Mod Recovery and Flash a Custom Rom on your device. Also since partitioning your sd card will erase all your data stored in sd card, it is recommended that you backup your data to your computer. Now that you have backed up your data please follow these simple instructions to partition your sd card and install Darktremor App2sd script on your android smart phone.
PARTITIONING SD CARD
_________________________________
1. Reboot your device into Clockwork Mod Recovery.
2. Go to Advance>>Partition SD Card option on your recovery and select a size (for ext 3 partition). This will create an ext 3 file system partition on your sd card called sd-ext. The size of your sd-ext partition should be determined on the basis of how much apps and games you are going to install on your device.
i have 1 Gb sd-ext on 8 gb memory ...
3. Also, select swap partition size as 0 Mb (select 64 or more for gaming purpose)
4. [Optional] Format your sd-ext from mounts and storage>>fromat /sd-ext option in CWM recovery.
5. Reboot your device and open a terminal emulator or shell commander and type in the following command to make sure that your second partition (aka sd-ext partition) is mounted at boot.
mount | grep sd-ext
You should see the following code:
/dev/block/mmcblk0p2 on /sd-ext type ext3 (rw,noatime,nodiratime,barrier=1,nodelalloc,data=ordered)
INSTALLING DTAPPS2SD
___________________________________________
6. Now download Darktremor Apps2SD (link bottom) and copy it to your sdcard.
7. Reboot your device in CWM recovery and then mount your data and system by going to mounts and storage>>mount /data and mounts and storage>>mount /system options respectively.
8. Now go back to main menu and go to install zip from sd>>choose zip from sdcard option and select the dtapps2sd-2.7.5.3-beta04-signed.zip file you downloaded from above.
9. After the script is installed reboot your device.
That’s all. You have successfully installed Darktremor Apps2SD on your device .
Note that the device will reboot again after you reboot your device. This is just to move all your apps to the second partition (sd-ext partition) and is normal.
Also if you want to manage your Apps2SD settings you can either use commands in terminal emulator or download the APPS2SDGUI application from market and manage everything from there. One of the useful command can be a2sd help. Try it on any terminal to see the help file that comes with Darktremor A2SD.
How to check if Apps2SD has been installed correctly...
________________________________________
The following information is for those who are still unsure of whether Apps2SD has been installed and if it is working correctly after root.
Open a Terminal Editor on your phone
When you have the client open, type "su" to gain super user access, and then hit enter. Now type "ls -l /data" and hit enter. You should see a few lines, a couple of which should read on the far right column:
dalvik-cache -> /system/sd/dalvik-cache
app-private -> /system/sd/app-private
app -> /system/sd/app
Notice the -> indicating symlinks and the 'sd'
You can also run: busybox df -h to check the /system/sd that the folder is being used
If this output is visible to you, then Apps2SD is working properly and you have installed it correctly. You will notice that by checking Menu > Settings > SD & phone storage, there is still some internal memory going down due to cache, other data, etc, but the main apps all go on the SD card given the above result. I currently have 29 apps installed (including Google Earth, which is 22.1 MB in size itself) and my internal memory currently shows 119MB of available space.
You can perform more extensive checks by executing the following command:
ls /system/sd/app (this will list all the apps which you have installed to the SD card)
CONFIGURING APPS2D
_________________________________________________________
open terminal emulator,, and type the following:
• a2sd check : Checks a2sd status; displays information incl. where your apps, cahce and data are stored.
• a2sd cachesd : Moves dalvik cache to sd-ext partition.
• a2sd nocache : Moves dalvik cache back to internal storage.
• a2sd data2sd : Move /data/data to /sd-ext/data .
• a2sd nodata : Move /sd-ext/data back to internal storage.
• a2sd remove : Moves apps back to internal storage and sets no a2sd flag.
or u can simply use app2sdgui to do things.. a help is given in app just proceed on installing the app and go to help menu
PRECAUTIONS: tips you should take in mind
________________________________________
After installing Darktremor Apps2SD don’t move your apps to sdcard either from Manage Applications Settings or by using app2sd pro or similar applications because it will ruin all your settings and your script will not work .
Also you may notice that your used space in internal storage shown in Manage Applications Setting is not decreasing even after you install Apps2SD and you may think that the script is not working. But remember if you followed all the instructions from above and got the same results as explained above then the script is working. It is shown so because system is fooled to believe that the apps are in internal storage but in reality they are stored in the secondary partition we created (i.e. in /sd-ext/app folder) on your device.
HAPPY INSTALLING APP2SD script...
