Cripes, so confused about DarkTremor A2SD on CM7

I'm really surprised that there is no documentation on this thing that I can understand. I'm having major issues with CM7 with DT A2SD. Every one of my widgets is broken. I can't tell what's installed to EXT and what's not. If I go into Manage Applications, all of the widget apps are installed to phone. I have next to zero internal space left.
I need to know how I can differentiate what's on internal, what's on Froyo SD, and what's on DT A2SD - As well as how to move them and tell where each app is going.

i honestly wish i knew. this is on my list to do, but i didnt feel like formatting my memory card cause there's so much on it, so i am just hoping gingerbread improved method will give me enough space.
i wish there was a tutorial or wiki for DT A2SD. you prob should just read that whole thread and it is explained there somewhere.

Some quick commands executed from adb shell or even the terminal on the phone can give you some more information:
a2sd check will give you basic diagnostic information from the DT a2sd script - this will reveal what is running where (apps on /sd-ext, data location, etc).
ls -al /data will help you understand what a2sd actually does for you. If a2sd is set up correctly, you should see an entry similar to "app --> /sd-ext/app", which indicates your /data/app directory is symbolically-linked to your /sd-ext partition (the ext-formatted partition on your SD card). This makes Android see /sd-ext/app and /data/app as the exact same thing, and everything within that folder will actually reside on the /sd-ext partition. The same thing applies to the dalvik-cache.
You can find out more about using a2sd via the a2sd help command, which shows an easy-to-understand listing of the various a2sd commands available.

All the documentation is in DarkTremor's thread.
There is no choosing in A2SD. If it's installed - all apps that are shown as "internal" go to EXT partition. But the phone doesn't know it, and you won't see it in OS visually in any place.
You can choose if you're sending your app data and your Dalvik-cache to SD also, that you can do from the Terminal (command line).
I should probably mention that all apps that are installed to SD using stock Froyo method, remain there - and cause a waste of space. So using A2SD you should move ALL your apps to "internal memory" (substituted with EXT partition).

This is a handy link for Darktremor users...

Hmm.. maybe I should had included some more info.
If I use Root Explorer and check my sd-ext folder, it does have apps within, and from install date I can tell they're from my CM7 install (plus I wiped everything including SD-EXT before flashing anyway). The problem is that some of these apps are things I do NOT want on SD-FAT or SD-EXT, I need them on internal (basically anything that I use with widgets, and LauncherPro). Pretty sure having widgets on EXT is what's causing my home screens to **** the bed.
Checked Install Location, right now that's set to Automatic.
If I go to Manage Applications, these apps appear to be on internal (Move to SD card is available on the button). I've read the FB page and original thread, I still see no way to differentiate between Internal, SD-FAT and SD-EXT - or how to move them between with certainty.

/sd-ext is the same as internal for all intents and purposes. You don't choose what apps to run off of /sd-ext, they all do. This is not causing your widget issues.
If you use DT a2sd, "Internal" becomes synonymous with "sd-ext". They are one and the same.
You SHOULD, however, move all of your apps off of SD-FAT - that is the implementation of "apps to sd" that breaks widgets.

Ok, I moved all of my apps off of SD-FAT and back to internal.. seems to be going well so far. The only thing I'm curious about now is that I didn't really get any space back, I still only have 21MB free (cleared browser and market cache as well). I've obviously messed something up somewhere along the line. Any ideas? I'm such a n00b at this apparently.
I really appreciate the help thus far guys!

You shouldn't have. Your space doesn't change as a result of moving apps to SD and back anymore - because they're all either on EXT, or partially on EXT and partially on FAT32.
If you don't have enough space left on internal memory - which can happen, if you have a lot of apps and they use a lot of data - you can move app data to SD and also Dalvik-cache to SD. This is done using command line commands.
One of those is usually enough.
I prefer the Dalvik-cache on SD - it might be a bit slower (never noticed that), but at least system settings (that are stored in /data/data) remain on the phone's internal memory and aren't prone to corruption.

On that note, moving the dalvik-cache is generally a better idea than moving /data/data. Better stability and compatibility and whatnot. Only bother with moving /data/data if you really really need the space.
You can move the dalvik-cache to sd with the a2sd cachesd command in either the terminal or adb shell.

OH MAN THANK YOU! Moved dalvik to SD-EXT and that did it! 120MB free! Time for a downloading spree!

[Q] why internal storage size still decrease after app2ext enabled?

i know this has been asked a thousand times, but i can't find the answer after 2 days searching...
i'm using milestone 1, i flashed latest cm7 rom following a tutorial here, version number CyanogenMod 7.0.1 0.08-11.04.24 (Android 2.3.3) , yes i know that i need ext2/3/4 partition on my sdcard. so i createdd one fat32 5gig primary partition and one 2gig ext3 primary partition.
later i installed around 80 apps , if i open root explorer, i see in /sd-ext folder, 251mb used, 1.60g free , i know this indicates that app2ext is working (according to some reply in that really long cm7 thread)
but if i come to the manage applications menu which comes with android, on the downloaded tab, it stills shows that 96mb used, 101mb free for the internal storage. is this normal ? will i get the low storage space warning in the future if i install more apps ? ( all the apps are in internal storage, the on sdcard tab shows all app is not in sdcard. i set default installation path to internal storage in cw setting , some apps still install themself to sdcard however, but i manually move them back by pressing the move to phone button.)
oh and i saw some tutorials saying i need to type some mysterious command in console in OR, so i can move and link some folders to ext partition, say /data/dalvik_cache and some other folders. do i need to do this for cm7 mod i'm using?
thanks if someone could show me the correct direction. I'm totally confused by the massive amount tutorials.

I believe that CM7 does not send the dalvik-cache of each app you install to the ext2 partition. So you still take up space on your phone, just much less.

I have this problem too. And after I cleaned chache and dalvik cache, my internal storage is almost full

[Q] Convert SDCard to MainMem so External_SD becomes SDCard?

Hi there,
Is there a way to make the add the internal SD card to the main memmory? So that there would not be an internal SD card anymore?
I do not mean swapping the moutpoints around so my External_SD becomes my primary and my internal my second....
I want to get rid of the internal one alltogether (adding it to main memory).
I figure that I'll have to format the storage in a certain way... would that do it?
Can someone tell me step by step what to do?
I do have CW-mod installed.
I did search the forum, but couldnt find anything conclusive. Just hints that it should be possible...
If there already is a thread where all this is explained, please point me to it, because I couldn't find it.
Thanks,
Pfeffa-rah

I don't think this is possible , never heard of someone who did it

I have no idea how to do that. My question is... why would you want to do that?
Having an internal_sd partition adds the benefit of having big app data (such as those in Gameloft games) sit in a very fast partition and still be called "sddata".
Also, it's mountable via PC so everything in there can still be backed up. So it's best of both worlds really.

This was discussed some time ago in this thread: http://forum.xda-developers.com/showthread.php?t=1013575
There were ideas on how to remount the cards at boot. I myself come to the conclusion that since more phones start to behave in this way, app developers will have to start dealing with it. It just sucks they are mostly slow on the uptake. My main problem was the Spotify cache location being hard coded so I resorted to hack the Spotify apk.
PS. salisbury_steak: What is it with people like you that every time someone has a question on how to do something, your immediate response is "But why would you want to do that?!".

That was actually an honest question.
I wanted to understand why he wanted to do it. (i.e. What would be the advantages of it.) There was no supposed sarcasm in there.

how about the ability to install 5x more applications?

Having that stupid 5gb partition as sd card and the real sd card as a sub folder is retarded...
My 32GB class 10 cars is a lot faster than the internal one.
The internal 5gb memory is MUCH TOO SMALL!!! Most apps don't allow you to store data on the external card. If you like me and many others install some games that download aditional data + a nav app that downloads maps for europe + some streaming music app like wimp that can cache music for offline play then you are ****ed with LG's setup.
The setup CM7 uses solves the main problem but effectively wastes the 5gb by mounting it at emmc where like 0,0001% of apps are able to access it.
So adding those otherwise wasted 5gb to the main memory would be great. But i have not seen any solution to that yet :-(

Thank you Gensplejs for explaining that to them. I had no idea how to reply to that since it seemed so obvious to me.
This thread was ment to be a question about how to do it and not to discuss the usefullness of it. That is where I lost the way in other threads...
So, thanks for your replys all (realy).
But now, back On-Topic:
How would I do it?
Sent from my LG-P990 using XDA Premium App

Please don't blame me if you tried it and you screwed up your phone.. It's your choice...
Well, I don't know if this would work, but this is how I would do it (accepting the fact that I'd loose almost 2GB of /data's free space):
1. Format your internal sd card to the same file system as your /data partition is (ext3 or ext4)
2. Copy every file from /data 1:1 to your sdcard (cp -R /data/* /sdcard)
3. I don't know when and where the partitions are mounted (maybe init.rc??)...anyways change the target there and let /data point to the internal sd card partition (so it is ensured that it is mounted automatically to the new location)
4. Reboot and keep your fingers crossed

I think i figured how to do it in theory. First we need some free space at our microsd to cp /data. Then we should repartition with fdisk /dev/block/mmcblk0p8 and p9 into one partition and change vold.fstab to mount only externalsd at /sdcard as we do when we swap partitions. In theory it should work but i cant test it right now or make a script since ve gone vacations and i dont have a pc to restore in case of error

I agree.. certain apps wont store to sdcard.. its better to use the whole 8gb as phone storage, and use external sdcard as default sdcard.
Sent from my LG-P990 using XDA App

What ive found till now is that sd swapping is easy. You can do it by tweaking only vold.fstab. But repatriationing is a pain in the ass. Looks like lg has "faulty" partitions or something and to do it you must mesh up with with almost half partitions.
I had to rebuilt boot lgdrm recovery data and sdcard to make em half work. So it probably isnt worth the trouble. Also I think init.rc is built on the boot. So just remounting internal sd to /data wont work either.

sectors is not space
it says 7996, so thats 8GB

i saw it in hurry. the brain sometimes belives whats he want to belive
sorry

New to XDA
Hello everybody,
I'm new to android and i'm trying to find out how to solve the problem posted in this thread.
I see you've got the awnser but i don't know how to do this.
I've been searching google and XDA for ever but i just can't find the awnser.
Could you make a step by step howto or point out to a post how to do this.
I mean converting your external sd to ext4 and change the mounting points.
I'm a complete nood, i didn't get adb to work on my pc, ext4 recovery is not for the p990 2x.
I've read something abbout changing fstap for swapping te mounting points for sdcard and emmc, witch is also ok for me, but formating to ext4... wel i frankly don't know how to do this.
I'm quite stuk on this.
The only partitioning experience i've got is Gparted in Ubuntu or repartitioning in Windows 7.
Thans in andvance!
Greetz,

you can expand data partition , but there is a limitation of 1.75gb

Thanks davjan
Thanks davjan,
As far i can see it's indeed not worth it.
I wil have to go on and try to find out how to change the filesystem to ext4 and swap the internal and external sd.
That way i get more usable space instead of a big datastorage witch cannot contain program data.
But thanks for the quick reply.

what rom are you using? is your phone rooted?
swapping internal with internal sd is very easy
and most of the roms here on xda are ext4 , if you instal one of them they autoconvert to ext4

I you read the link provided you'll see that it makes what you want: grow internal filesystem = lower SDcard usable space. The only thing is that it doesn't seem possible is to use the whole space: system limitation. 75Markus tried high /system and /data values and phone didn't work.
See in his Mediafire Folder, 'Nvflash + guide for changing Partitions:
http://www.mediafire.com/75markus
Ext4 is now common with custom ROMs (in fact all of them).
You should search in sd-ext partition system, which was designed to artificially expand filesystem on older phones using an 'ext' partition. I didn't heard anybody using this on O2X.
If you use CyanogenMod based ROMs, your external card will be mounted ad /sdcard by default.

Switching internal and external SD
Thanks guy's,
I'll check it out.
I've been using cyanogenmod 7.1 stable with vorkkernel 20110208.
But that gave me batterydrains while using maps and nextvid ate the same time (while i'm driving).
Now i'm trying MIUI 1.11.11 with latest swift extreme.
But MIUI is very buggy so i'm thinking of going back to CM.
The only thing is that my phone won't boot with the latest vorkkernel.

[Q] Use full Nook eMMC capacity for CM internal storage?

Just got my Nook Color tonight. I booted it from a CWM microSD card, installed CM 7.1 stable, gapps, and ran ROM Manager to install CWM to internal memory.
When I go to Menu, Settings, Storage, under the 'Internal Storage' heading, it says "Total space" of 5.09 GB and "Available space" of 4.68 GB. (One app installed so far)
Looking farther down the screen, it shows /mnt/eemc to have 1.00 GB of space.
Is there a way to combine them so that I have 5.68 GB of usable internal space to install apps to? Also, are those two the full available capacity of the eMMC storage? If not, can it be enlarged to maximum?
Also, further down the screen, it shows /mnt/usbdisk, with no space. Should it be left intact, or can it be safely removed to limit my confusion?
Thanks!

+1 to your question.
I'm gonna use my NC only as a tablet not any book reading so I don't think that 1GB is required.
Still let's wait for a dev. to give expert advice about this and possibly a how-to...

I would leave /mnt/usbdisk alone as it will be useful if you decide to use flash drives through nook tweeks in the usb section. As for the emmc data area, you can store data there with no problem if you are not going to use the nook as an e-reader.
By downloading the nook tweeks app, you will have access to the micro usb port (through an adapter) to transfer data between the nook and a flash drive or (using a powered hub) a card reader. You can also transfer data between the nook and a camera to directly save photos to the nook or view them. Usb host mode opens the nook up to another level and makes it a very functional tablet.
I use my nook with a digital camera on photo shoots so that I can preview my shots on a larger screen than that of the camera. You can check out my threads here concerning host mode. PM me if I can be of any assistance.

Hey there, I know long time but iI have some info to share since I'm having the same configuration as yours.
The 'Internal Storage' you're seeing isn't exactly the emmc. Its just that cm7 doesn't know its put on an SD. And it thinks the second or third partition of the SD (i.e. cm7 system partition) is internal.
Also that /mnt/eemc is the actual internal memory and thus these 2 can't be linked. However, the nook has another 5gb emmc internal partition callednmedia which you can possibly combine with emmc.

there are many threads about the NC partition layout and changing it. do a search. the 5g partition basically won't be used by your cm7 NC. the apps will go on the 1g. I repartitioned mine for 4g instead of 1g and 2g for /emmc. then you can set cm7 to swap the /emmc and /sdcard and then use the NC without an SD installed.

Yes, I understand that's what you want to do. However, those partitions are not contiguous space. Search on Nook Color partitions and you will quickly see why.
Specifically, look here:
http://forum.xda-developers.com/showthread.php?t=1094371
which links to here:
http://forum.xda-developers.com/showpost.php?p=13971291&postcount=110
/dev/block/mmcblk0p6 is the "data" partition
/dev/block/mmcblk0p7 is the "cache" partition
/dev/block/mmcblk0p8 is the "/mnt/emmc" partition
You are wanting to combine "data" and "/mnt/emmc". Problem is the "cache" partition is stuck in between them.
The other problem is your NC uses these two partitions for different things.
I think the suggestion I made before, which is to repartition for 2GB+4GB as in the first link, then do Settings -> CyanogenMod Settings -> Application -> Use internal storage to get them to swap, is the best, simplest solution with the lowest risk. This uses the 2G partition for whatever normally is used for /sdcard by most apps (downloads, misc. files, temp storage, etc.) and 4G partition for your apps, and leaves your whole SD card for use solely for your side-loaded media content. This schema will not interfere with further CM updates or unnecessarily change the default partition scheme for which most of the devs are writing code.
If you want to become a Linux & Android master of partitioning and storage management, then you can probably implement a more custom scheme. In my last job I was a software engineer working on a Linux-based network-attached storage appliance and I wrote most of the system code dealing with disk and partition management, so you could say I know a lot about it, but still I chose the easy path for my NC.

How to move apps from external sd to internal sd

So I have four partitions in my galaxy mini :
System rom 216mb (21.4mb free)
Internal 479mb(447mb free)
Sd card 15.3gb(13.5gb free)
Sd card(a2sd) 187mb(8.54mb free)
When I try to move my apps to sd card using the default move it moves to sd card(a2sd) and not to sd card .
So how do I do that ? + Is their a way I can move stuff from my system rom to other partitions ?

sdcard, external_sd
a2sd is moving apps to your other partitions. the 16 gig card you got has to be the one where you got to move apps. all apps are stored in your internal memory. the system rom is read only, so you wont be able to move or erase it. its permanent, programmed at the factory. so forget rom. if you formatted your sdcards correctly, then you must be able to delete partitions, or reformat them. i recommend deleting the partition after uninstalling all apps on that partition. remember, you are rooted, so if you have root access apps on that partition, then you first have to undo everything the apps did. eg: if you have chainfire, then you got to remove all plugins(qualcomm, nvidia, powervr if installed) the cf3d plugin with egl if installed, then uninstall cf. connect your mobile via usb cord, or get your sdcard in a memory card reader, connect to pc. use "device manager" in your pc to see all partitions of your hard drives. look for your sdcard drive, and you will see all types of data divided in it, that is, formatted data, raw data, etc. if you see raw data, then you have to format it, and its likely that you will be done there. but i f you see formatted data, then just delete the 8 mb partition, and then its possible that you may succeed. this is dangerous, and your data can sort of "vanish", but it will only be the 8mb data according to me. its also possible that you may not be able to delete the partition after all, as this usually works for hard drives. if so, you may use hp format tool to format your device to NTFS and try again. this also can make your data vanish by what you say. the simplest would be to try and delete the partition from your mini itself. the app which you used to partition must allow you to remove partitions also, so look for it. and if this particular app is in the sdcard(a2sd), then you would better move tit to phone memory first. remember, uninstall ALL apps on the partition, and undo ALL the changes they made to your device before trying this out. this may horribly go wrong, so beware! (i havent tried it yet, so. and someone gifted me an ipod 5g, which i tried to partition, but was unsuccessful.) just hit thanks if you find this helpful!

Link2SD is an application that makes it easy for Android 1.6+ users with root privileges on their phone to move applications to the SD card.
The idea behind is same with apps2sd scripts, linking applications to SD card's second partition but differs in two ways.
One, instead of linking /data/app folder (that means moving all applications), you can select applications that you want to move.
Two, it's an application which means has a user interface. You can manage your applications with few clicks.
It also provides native apps2sd features on Android 2.2 and higher. It can move any non-protected user apps to SD card (force move), with batch moving capability.
That feature uses Android's standard SD-card installation feature and does not require a second partition. It can break some apps if they are not meant to be moved to the SD card (Such as Widgets).
Features:
- Create and remove link for apk, dex and lib files of the applications you select
- Automatically link newly installed apps (optional)
- Move any user apps to SD even though the app does not support moving to SD (a.k.a. "force move", for Android 2.2 and higher)
- Shows the apps that support moving to SD with native apps2sd (for Android 2.2 and higher)
- Set the default install location of the apps; auto, internal, or external (for Android 2.2 and higher)
- Batch link, unlink, reinstall, uninstall, "move to SD", "move to phone" functions (multi-select mode)
- Uninstall system applications (bloatware removal)
- Freeze and un-freeze system and users applications
- Convert system apps into user apps
- Convert user apps into system apps
- Integrate "Updated" system apps into system (ROM)
- Clear data and cache of the application
- Clear all apps cache at once (1-tap cache cleaner without being root)
- List applications, show detailed size information and link status
- Sort and filter applications
- Search applications by name
- Display available space information of internal storage, SD card and SD card 2nd partition
What you need:
- root permission.
- a second partition on your SD card.
You should have two partitions on SD card and both should be primary.
The first FAT partition is your standard SD card storage. The second partition is used for application files and can be ext2, ext3, ext4 or FAT32.
Some phones lack the ext2, ext3 or ext4 file system support and you may get mount errors like "no such device", "invalid argument". These phones need ext2.ko or ext3.ko modules and even some additional modules to be able to mount. Using FAT32 on the second partition will eleminate such problems, because FAT32 is supported on all phones.
Link2SD does not create the second partition, you need to create it yourself. You can use any partition manager such as Minitool, Paragon, Easeus etc. for this.
How it works:
Link2SD mounts the second partition of your SD card and makes OS mounts it at boot time.
When you press "Create Link" button Link2SD moves apk file, dalvik-cache (.dex) file and lib files (.so) to SD card's 2nd partition and creates symbolic links in original directories.
Note: On Android 1.6 and 2.1, shortcut and the widget of the app should be re-added to homescreen if you move the apk file.
You can remove the links and put application files back to phone. Just click on "Remove Link" button.
Some points
- System applications should not be linked to SD card. Link2SD does not allow these applications to be linked.
- When you connect your phone to PC as mass storage, Android unmounts the first FAT partition but the second partition remains mounted. Therefore linked applications are not affected and can be run without problems.
- Link2SD does not move application's private data files; it moves apk, dex (dalvik-cache) and lib files.

To move apps to sdcard, use link2sd and long press the desired app & select "Move to sdcard"(if u have root).
