Ext3

Hi.
I'm in a dilemma here trying to.fimd out what is wrong. I formatted and partitioned my 4gb SD card to work with App2sd+ by making 3gb Fat32 Primary and First Partition and 1gb EXT3 Primary, however whenever apps are installed they tend to use the First partitioned instead of the reserved 1gb partition I had created.
Maybe I have done something wrong, since I am quite new to App2SD and how it works, but know the basics. I would appreciate your help.
Thank you

You must flash a rom with a2sd+ support. It's different from the built in support for a2sd, which can be found in the stock froyo roms and above.

Flash Darktremor Apps2SD for Desire in recovery and then use A2SDGUI from the Market to change settings as you like. After that do not manually move apps around. They should me installed to the internal storage which then will be your sd-card.

I failed to metion that I am using Teppic's 'Pre-rooted Stock Froyo (2.29.405.5)' ROM with the optional addon 'App2SD+' so I presume it should work fine
However, I am thinking it has something to do with the app I have installed 'Move2SD Enabler' which I think is moving everything to the External Fat32 partition'.
Can someone confirm?

yes it could be, i wondering the same things about the app2sd with my first flash with custom's rom and ap2sd+ (i uninstalled this app).
to be shure that your sript ap2sd+ is working fine you can brouwse your phone and go to system/sd you should see 4 folders... app + app-private +lost-found and dalvik-cache (for the last folder it's assumed that your script got the little "+" which means that is moving the dalvik cache to your ext partition)
hope this would help you

Another idea to see if a2sd+ is working like it should is to download Quick System Info. When you launch it you should see a line with a2sd info. If it is there then a2sd+ is ok, and you can see how much of you ext3 1GB partition is used.

I used the rom manager to make the partitions, then I format them with MiniTool.Partition.Wizard.Professional.v5.2-REDT when needed, you can resize them as needed ... you can download it at rlslog.net

Wow... Is it really time for another "how does x type of app to sd solution work?"
It really is quite simple:
Froyo a2sd uses a folder on the fat32 and the system controls, where the apps is installed, and where they are moved to.
a2sd+/legacy a2sd uses the ext-partition by symlinking the folders /data/apps and /data/dalvik-cache to this partition. This solution is transparent to the system itself, so as far as the android system is aware the apps is installed internal. This means you can use widgets from apps on this partition, and it also means that your apps will allways be installed here, so you cannot move them to internal. You will also not see the extra space, your apps will just not take up as much space when installed.
If you like you have done move the apps to sd through the froyo settings, you actually just move them from the ext-partition to the folder on the fat32-partition.

[Q] A2SD+ and low internal memory

I haven't found really good explanation on forum and most of post on this seems not to be answered so I'm posting to see if I can get this sorted.
I used Leedroid, InsertCoin, and now on GingerVillian now. All of them had same setting of 500MB ext partition. Problem is I always seems to get low internal memory no matter what ROM I use. Currently I have 394MB free SD-EXT and 16MB Internal.
I moved adobe flash to SD card which seems to free up space and Dalvik Cache is on SD-Ext.
So question is why even though I have lot of EXT space left is it not being used and is there way to make it use it more instead of internal memory?

App2SD is flawed because of this, say you have an app 20mb, 15mb would be put on to the SD card and the rest go's to internal, so you will still use up space and in the end will have to start uninstalling.
Best way is to use a Rom with data2SD witch give's you 2gb internal memory.

Data2SD RoM problems solved

One could also flash a new hboot which increases the size of the /data-partition. However you need s-off for this and it's imho riskier than flashing a rom with data2sd. Whereas i work with a2sd + cm7 hboot and i am very happy it.

Desire with Cool Sensation v7
Hi,
I have this problem too. but it is not our choice to choose the data2sd instead of app2sd because it depend on what the ROM support.
Previously I use App2sd+ from ModaCo ROM. I have 200+ apps and it take the internal memory nearly full but sd-ext space just half.
I tried the Data2sd for Desire is only SuperNova with HTC Sense and it work in 1Gb sd-ext. BUT it uses Sense 2.1.
I just try Sense 3 from Cool Sensation v7 ROM. I love it and dont want to revert back to previous Sense It have 3D home screen, cool weather animation, SMS secure lock. However this ROM still use app2sd. I cannot post to the thread, I dont have enought post count.
I try some other way to apply Data2sd into this ROM but I got boot loop.
After few days I use this ROM, my internal memory almost full (15mb free) for only 57 apps even the app2sd symlink-ed /data/app, /data/app-private, /data/dalvik-cache and /system/app into sd-ext!
Expert please help me and give me some idea.
Do I need to symlink /data/data into sd-ext manually?
Is it possible to remove app2sd in the ROM and install Data2sd? How?
Data2sd require busybox, init.d and ext4 kernel support. I think this ROM have all this thing.
HTC Desire
Hboot S-Off with Revolutionary
4ExtRecovery
Cool Sensation v7 ROM
8Gb Class 2 sd card with Fat32 + 1Gb ext4
And have some basic in Linux shell

I can 100% get my head around this either, although i did install some apps and i could really tell if it was on Internal or EXT4.
From my understanding, as far as the phone os, it thinks apps are on Internal and will decrease the size counter, but apps are on EXT4 if you use a file manager etc.. but even if all goes to EXT4, we still get that annoying LowDisk message was it get to 15megs...
I still was convinced, but i accidently decided i wanted to format my FAT32 partition, mainly to get rid of all the junk that on there since STOCK Rom. I used the Phone own Format SD Card option.
Well that was fun (NOT!!) it instead formatted the EXT4 and not the FAT32, when i rebooted all the loaded apps that were on EXT4 were now gone.
Phone still works, but one side effect of this is now i have like 270megs free....lol, granted no wallpaper, lockscreens etc,
anyway seeing as i screwed up and that im already S-OFF, im going to just go with CM7r2 HBoot.

Similar issue - I think?
Hi all, my first post here
So I have been working my way through all the error messages and guides and finally have InsertCoin set up. All is looking good except after Titanium Backup restored all my apps my internal memory is as full as before I rooted the phone, so I think I can safely say that the 2gb I partitioned off on my SD is not getting ay use at all? Is there a way I can check?
For the record I am running with AmonRa, and I used Revolutionary to get s-Off. The guide I followed to set up A2SD did not have me using any Terminal commands, so I am guessing that is an area for me to explore in solving this, here is the guide I used (near the end)

I used that method as i am on a borrowed mac and it just seemed easier. I
I am hoping there is an easy fix that someone can suggest.

To check if a2sd is working, open terminal emulator and type
Code:
su
ls -l /data
Output should say (for a2sd):
Code:
app -> /sd-ext/app
app-private -> /sd-ext/app-private
Additionally for a2sd+:
Code:
dalvik-cache -> /sd-ext/dalvik-cache
If it does not show this, a2sd is not working. So make sure you partitioned sd card correctly (fat32 + ext; both primary).

I used Cool Sensation v7 but didn't have this problem until I flashed the newer v9 (just noticed v10 has been posted today though). My internal memory was very low but I then flashed the Dalvik to sdext.zip from the Cool Sensation thread and then had 180MB internal free. Try that and see if it works. If it doesn't, have you aligned your SD ext using the .zip on the same thread? if not this could be why your having problems, though it didn't work for me.

Thanks for the ideas, I was a bit out of my depth with the Mac SU functions, so although i didn't get the desired feedback you suggested, but it could have been me. So anyway I found a Ubuntu machine and plugged in the SD card in an adapter and can see that there is a successful partition, and that the EXT partition seems to have some files and folders in it.
I have also just noticed that the SD cards partitions also appear in the Titanium Backup overview screen.
So i guess my problem is that the memory is just full! Maybe my expectations of extra memory after rooting were unrealistic. ?
For the Record, just to make sure my situation is normal, in Titanium I see
System ROM - 262MB (129MB free)
Internal - 158MB (15MB free) - is this just a section of system ROM above?
SD CARD - 13.8GB (11GB free)
SD Card (a2sd) - 1.9GB (1.5GB free)

@xybadog this is my update,
@hoads1234 just want to share with you,
I use Cool Sensation v7, the internal memory full can be solved by flashing the additional zip for stock hboot but I flash non stock hboot. Why?
After some studying, now I know why expert keep asking for my hboot. Hboot define the data partition. On the phone memory, it divided into system, cache and data partition. the hboot define the partition size. For stock hboot, you will only have 147Mb for HTC Desire. Whatever the custom ROM symlink'ed some data partition, we stuck on 147Mb. If you flash like CM7r2 hboot, you will get more room (300+Mb) on data but just enough for system. "Internal memory" is referring to data partition.
Now I still have 130Mb free internal memory after installing 90 apps without wiping any cache for about 2 weeks.
I dont have Ubuntu even I know how to use it. No time to install or make virtual machine. To partition your sdcard easily without linux, use 4ExtRecovery. It is CWM based recovery plus support for Ext4 and some features like partitioning, check for aligned sd-ext and mount as disk drive.

To check for your current internal partition. boot into recovery, and use ADB to run command "df -h". The /system /data and /cache is the thing you need to look for.

You could use the cyanogenmod rom, then install s2e app from market. That app is designed purely for use with cyanogenmod. I use this combo, I have a huge amount of apps installed and still 50mb of internal space free. No need for changing your hboot or using data2sd rom. Very simple fix
Sent from my CM7.1 Desire using XDA Premium App

okay thanks, I am still happy having a go with InsertCoin, so I will have a look at the hboot.
I think i read somewhere that i could do it just like adding a new ROM and copying a zip file across, so time for some more forum reading to work my way through this next step.

http://forum.xda-developers.com/showthread.php?t=1110921

okay here is my update, since in have revolutionary hboot, i tried to change to alpharev, so i could use their modified partition tables (found no reference of being able to do this in Revolutionary) - the folks on alpharev irc said not to, but didn't say why.
I did try and use the unrevoked tool to flash AmonRa across again, but this had a waiting for reboot error and may have failed. I have also reflashed my ROM again after a full wipe a couple of times. Not finding any improvements in memory, so will keep fiddling.

okay next question!
I tried the terminal emulator commands (once i worked out this was an app, and not the Mac terminal..) and got the following responses
app -> /system/sd/app
app-private ->
dalvik-cache ->
so am i guessing correctly that none of the apps i download are being sent to the SD partition.
Any advice to get app-private directed to my sd card?

I suggest you use ADB instead of terminal emulator because easy to type in PC.
Install Android SDK make ADB shell to work and connected to your device. The shell is just the same what you need to do in terminal emulator.
To move app private and dalvik cache simply make symlink like this:
Code:
busybox cp -a /data/dalvik-cache /system/sd/
rm -rf /data/dalvik-cache
ln -s /system/sd/dalvik-cache /data/dalvik-cache
The first will move all contents, the second will remove the existing original dalvik-cache folder. and the third one will make symlink to point from original location to the sd partition.

Apps2sd

my ROM is a apps2sd ROM. Ext sd is reporting use, i.e. I set 1g of ext and storage says 658mb of ext is free. But in applications my apps give me the choice to Move to SD! ?
I used TB pro to batch move apps to SD but altho my apps now report they are on SD. Ext usage actually went down after the move. Am I confusing Apps on Sd / ext ? So on roms with default apps2sd you ignore in applications that they appear to be on internal mem?

Yes ignore it. You've just moved your apps from ext to fat. Read the root memory faq in my signature

I've some A2SD questions as well. I'm on CM7 with several apps already installed. My 4GB SD card has already been partitioned to 3GB FAT32 and 1GB ext4.
I was getting low memory warnings so I applied the darktremors script (stable, not nightly) expecting it to automatically move my apps to the sd card like your a2sd guide said it would. However, I still got low memory warning, so I manually moved the app to sd card using manage applications. This however moved the apps to the FAT32 partition, and several of my apps suh as my clock widget and swype no longer work.
How to I get my existing apps to move to the SD card's ext4 partition?

They need to all be moved to phone.
The apps should automatically move to ext download quick system info to check a2sd is working.
If its not try "a2sd reinstall" from terminal emulator.
Dalvik-cache is not moved by default and takes up a whole load of space so don't forget "a2sd cachesd" too
Sent from my HTC Desire using XDA App

OK, I thought the a2sd would move existing apps as well, didn't know I needed to "a2sd reinstall". Can I do the reinstall through an adb shell or do I need to download a terminal emulator?
I don't have a Class 4 card, it's a generic card and I don't know what class it is, so should I move the dalvik-cache to the cache partition using "a2sd cachepart" rather than "a2sd cachesd"?
Do I need to wipe cache and dalvik-cache before running any a2sd commands such as reinstall and cachesd/cachepart?
Lastly, do I need to reboot the phone after running these commands?
Thanks.

Ive never seen any performance issues even on class 2 cards. Keeping dalvik on NAND may give a miniscule performance increase, but I think its so negligible, you wont notice. But put it where you want. I recommend card though as you need the cache partition for downloads and as it fills with dalvik, it will limit the size of apps you can download from the market.
a2sd reinstall is for if it doesn't work properly. Its always the first thing to try. Then move dalvik. The way dalvik move works is that it wipes dalvik, moves the location then reboots the phone (rebuilding dalvik so expect delays when booting up the first time). For this reason its best to use "terminal emulator" from the market.
Hope this helps.

Alright, thanks! Will try reinstall and moving dalvik cache to the sdcard. Might get a new faster card since 4GB is getting tight anyway.

Tried the reinstall and it seemed to work. I had to move my apps back to the internal memory in 2 batches since I was running out of internal memory. So here's what I did
1. Move batch 1 of apps from sdcard back to internal memory
2. Run a2sd check in adb shell
3. Run a2sd reinstall in adb shell
4. After phone rebooted, checked my storage to find about 50MB of internal space left (woohoo!)
5. Move batch 2 of apps from sdcard back to internal memory
6. checked my storage to find still about 50MB of internal space left. I guess this means a2sd automatically moved them to the sd-ext partition?
When I ran a2sd check in step 2, the output showed that my ext partition type was ext2 rather than ext4 which I formatted the sd-ext partition to. Is this a mistake?
Will try moving dalvik-cache perhaps this weekend.
Are there any benchmarks I can run on the sdcard to make sure it's fast enough for dalvik-cache? Perhaps HDTach/CrystalDiskBench/ATTO/AS-SSD Bench/etc? There aren't any markings on the sdcard that indicates its class. It's a generic HP 4GB sdcard. Will a "dd if=largefile of=/dev/null" for read and a "dd if=largefile1 of=largefile2" for write work?

I've never known a card too slow for dalvik. Just move it. You can move it back again
Sent from my HTC Desire using XDA App

I believe the ext2 is due to some error with a2sd check. I encountered it too when i used the command and i was using an ext4 partition.
As for dalvik, try moving it. If it too slow then move it back.

Sorry, yes its a bug, fixed apparently in the latest BETA.

Don't think I'll be playing with the phone for a while - it's my wife's phone, and it took almost a week for me to figure things out and start from stock to CM7 with A2SD...now it's relatively stable with quite a bit of internal memory available, so I think I'll keep it that way for a while.
Thanks for all the help!

Hello rootsu,
i installed a Data++ rom and now some applications that i install, not from market, disappear after a reboot. From the market it is fine but if i put a .apk in the card and install it, disappear after reboot. Not all of them. Only some of them.
I have a aura sygic gps and this is one of them that disappear after install. The only way that doesn't is to move to the card. And another one, that doesn´te have the option to move to the card, disappear after reboot.
I already wipe dalvik cache, wipe everytnhig, rom install again, etc...
What's the problem? Do you now? I've searched a lot but i cant find anything.

That's a new one on me.
Install, take titanium backup, boot recovery, factory reset, format /data, titanium restore?

The cache system space is from sdcard memory or memory phone?

Although I am not rootSU, I feel free to answer:
I am pretty sure it uses space of SD Card. Using internal memory would be a little strange, especially we are talking about 160 MB here.

[Q] Apps2sd not working! Please help!

It's the second time I try to configure my phone for Apps2SD, and it just doesn't seem to work! I've got a HTC Desire GSM, running MIUI 2.4.13. This time i've configured my phone to Apps2SD following the guide in this thread: http://miuiandroid.com/community/th...tall-of-miui-with-enough-room-for-apps.15808/
I did everything just like he said, and with regards to the partitions, I allocated 1024MB to one partition, 0 to the next partition, and 512MB for the swap partition. Then I chose EXT3. But there is no diference in my storage... I still only have 29MB free (out of 105MB) after installing apps.
Please help! What am doing wrong? This is really frustrating me..!

In order to work properly, the partitions must be created in this order: fat32, ext4, swap. Did you created them in this way? I suggest also to make partitions on your sd-card with gparted live or 4ext recovery (search this in the development section).
If you did it like that, in miui you have to enable a2sd:
download terminal emulator from market.
Type:
su
(enter)
a2sd reinstall
(enter)
(the phone after a while reboots)
if you want to move also dalvik to have more space (but less performance) type in emulator:
su
(enter)
a2sd cachesd

I've tried both terminal codes. Something is definitely working, because I've installed all the apps I used to have before and a few more, without moving anything to the SD card, and I've still got 27MB out of ~150MB.
Question is: If all the apps are stored on the SD card, why does the internal memory keep running out as I install more apps?

It's normal. A2sd move app (and dalvik if you type cachesd), but app's data remain in internal. If you need more space you have to choose data2sd script, it uses ext partition like internal, but affecting performance, overall if you have a low class SD-card. The best choice is to move app and, if you need more space, to move dalvik. Darktremor's a2sd is the first, most solid and stable script to do this, and it does very well.

Okay that makes a lot of sense, thank you.
I've got a class 6 microSD card. Is that good enough for data2sd? And how do I go about doing it? Am I going to need to wipe and partition all over again, or is the current configuration I've got sufficient?

Yes, class 6 is good. I have it too. But use data2sd only if you need more space. If you don't, don't use it, your phone may lag, have less responsiveness, etc..
You can find MIUI-XJ in developer section that has data2sd implemented.
Also you can try other script like m2sd by dk_zero-cool and xa2sdx by amarullz.
I never use install them separatly, so read instructions in their trhead.
Maybe you have only to wipe dalvik and cache but I am not sure.

[Q] SD-card partitioning / storage layout on desire

Dear XDA forum,
since a few roms i always get a "low on storage" warning, even after factory reset and flashing a new rom.
So i'd want to ask for a small summery of what storage there is inside the desire and on the sdcard and how to solve this problem
My sdcard is 16GB class 10. I didnt partition it manually (i think).
according to my desire it has effective 14.2gb.about 2gb are used and 4gb are free? that doesnt sound right.
so i guess its 2 partitions?
could anyone please tell me which mountpoint is which?
and how do i solve the low storage problem? do i need some a2sd script or do i have to more the internal storage to the sdcard?
which mountpoints do the scripts actarlly move?
i have no problem with repartitioning my sdcard. i was given to understand that u usually need a fat32 partition (for apps i guess) and an ext2/3 partition afterwards. some scripts even allow a swap partition at the end of the sdcard to be used as swap space. is that a good idea?
i know its a lot of questions :/ but i hope for some good answers :>
thanks & greetings,
soomon

my advice would be to backup your sd card and (re)partition using gparted, start from scratch because I don't know what your current configuration is, step 5 here
choose ext3/ext4 partition (max ~1.5GB) depending on rom requirements, most support ext4 and should be slightly faster. most roms don't need swap partition.
in simple terms, your space will get taken up by apps (apks), dalvik cache, app cache and app data. most custom roms will automatically move apks to your sd-ext partition. there are various different scripts which move the other bits around. generally it is better to keep app data on internal (/data partition)
regardless of which rom you choose, use an app like 'diskusage' to browse all your partitions, so you can work out where and how all your space is being use.
to maximise space you also need to be s-off and correct hboot for the rom (again should be stated within each rom thread, or search within it)

ok so the first partition on the sdcard will become my sd-ext which will replace the /data partition on the internal storage.
I guess is hould try data2sd then?
with a class 10 it should not get that slow and i get loads of space on that partition.
thanks for your help.

also use links2d,very usefull.....

hi again,
as i see in a terminal emulator by typing "df -h"
my data is 150mb and has 15mb left, so i guess i better moe the whole partition to the sdcard as i'd have to move all the apps to the sdcard anyway sooner or later.
my /system has only 5mb of 250mb left. is that a problem?

depends entirely what rom you're running if any, and what scripts it uses. basically you should be able to find some way to install many apps without running out of space (one of the main reasons for rooting in the first place ).
with your current setup, you could try something like link2sd to just move apps and dalvik to sd, see if you have enough space that way. you shouldnt have to manually 'move to sd', keeping them on 'internal' tricks them to sd-ext. (you can use something like 'diskusage' to check they're actually on the sd-ext)
the system partition is meant to be mostly full. free space on /system is wasted space.
you're still on stock hboot, which is why your data partition is so small.
if you install another rom, many of them have a smaller system size, so if you're s-off you can flash a different hboot to repartition your internal memory layout: your system size will reduce to roughly match your rom, and the saved space is converted into extra data space, see alpharev.nl for hboots.
e.g. if your rom system is 140MB, will fit nicely into cm7r2 hboot with 145MB system, and you get 287MB of data instead of 150MB. 287MB can be enough to store app data and dalvik cache if you don't have too many apps.
i refer you to these sets of guides for further reading, should explain a lot more, and better than i have...

thanks eddie,
i'm still s-on and stock hboot, but i use a custom rom: http://forum.xda-developers.com/showthread.php?t=1766550
i guess the problem is that LBE gues 4 and lookout together need over 22mb of space :/
i'll try link2sd then.
thanks!

hm.. when i try to install link2sd i get "insufficient storage available". that program is not even 1MB in size and i have 15mb of free space on the internal storage.. what can i do?
edit: i'll try to install it at home with an adb tool. maybe i have more luck with that.

follow instructions for a2sd with that rom (scroll down). this will move apps and dalvik to sd-ext automatically. or follow/search the thread for other methods, it's regularly discussed...
[not used link2sd, it should in theory do the same thing, but my advice would be to stick with the instructions as that's the recommended way if you really need/want to install link2sd...uninstall something else to make more space ]

ofc removing apps might help (althrough i only installed 2 or 3). but 15mb should be enough to install a 800kb software
gonna try to install some apps later after running a2sd.
thanks a lot man didnt see that information.
