Hi Guys,
I would have tacked this onto the back of an existing thread, but the only relevant ones I could find were in development (I’m still under 10 posts) – and this is more of a general usage question anyway.
I’m running CM7.0.2 and been I’ve been using Apps2SD (darktremor) for a month or so. The onboard memory for apps on the Legend is abysmal, so freeing space up and being able to have more than half a dozen apps is great. I was looking to take up Data2ext too. I’m still S-ON (I haven’t found a serious need for S-OFF yet, and I figure the less access I have to the bowels of my phone, the less likely I’m gonna brick it), so still using CWM2.x and obviously not running EXT4 yet.
Just wanted to ask a couple of stupid n00b questions before I try anything (I’d rather ask this now, then be posting “help I ****ed up my phone” later on).
- Am I right in believing that that data2ext only moves app data, not the apps themselves to the SD car so I need to continue using apps2sd as a companion script?
- Does data2ext need its own additional partition setting up prior – or does it create its own partition/utilize an existing partition? If there needs to be a preconfigured partition, any recommendations on how much space to allocate?
- Is there anything in particular that I need to know before I run through TGF’s guide (http://forum.xda-developers.com/showthread.php?t=902395)?
Thanks for the help guys!
data2ext will use the partition that darktremor currently uses, and you don't want to have dark tremor and data2ext on at the same time, funny things happen.
Data2ext remounts the entire data partition to a partition on the SD card. So anything that gets written to /data (apps, app data etc) goes to the SD card instead.
You need to know that this could go wrong, but I think the first post covers most of it.
That makes sense. I previously wasn’t sure if data2ext only moved app data only, and apps2sd still needed to be used to move the actual apps themselves. As that’s not the case, it’ll make things much easier not having to **** around with 2 different scripts to hopefully get them to play nicely.
I did actually end up stepping up to Blayo’s fake-flash CWM 3.0.1.3 yesterday; though I’m still trying to work out partitions/file systems with it – creating partitions in CWM recovery defaults to EXT3 with no option to set EXT4, and after manually creating an EXT4 partition in GParted CWM wouldn’t let me mount /sd-ext. As your initial post already details formatting /sd-ext to EXT4 anyway, it’ll be interesting to see how nicely this plays with 3.0.1.3.
Thanks for the disclaimer on the risks involved. Without intending to sound patronising; I’m well aware there is the ever present potential to really **** things up, and that I do only have limited knowledge compared to a lot of people posting on xda – which is why I try and get any/all information available before hand, and follow instructions given closely.
Coo'. Just shout if you need help, I'm subscribed to this thread so I should see it
Seems to have worked like a charm.
One question though – I know you can confirm data2ext is successfully running by launching "data2ext --enable" a second time after the final reboot, but is there any means to monitor the used/available space on /sd-ext?
Both Titanium Backup and a2sdGUI allowed me to keep tabs on this, but Ti is unable to see the /sd-ext partition now (I haven’t bothered installing a2sdGUI, not really any point).
It might be a small thing, but if possible I would like to be able to see it fill up, just to give me piece of mind all is OK.
*edit* scratch that last part, just noticed Android and Ti now sees the Internal Memory as a total combined capacity the internal memory + /sd-ext. Eitherway, I'm up and running
i no my question is noob but still.....i m using CM7 nd CWM 2.5.0.7....if i use d optioned partition ur sd card....is dat data to ext ? ndnd wat is swap size ? also how to check what claSS SDCARD I HAVE... I HAVE 16GB KINGSTON SDCARD!
I've a noob question too, if the sd card is partitioned to allow some internal apps to run on this special partition what is currently the safest procedure to do this?

I got mine up and running last night... created a 1 gig partition for data... data2ext is active, but my phone is now SLOW as molasses. SD card is Class 10 and tests on a computer reveal it to be fast.
I'm at a loss.

The card probably doesn't handle small files very well. Class 4 seems to be the best bet for data2ext
You're kidding. Ugh! Maybe it was the method I used to format?

Seriously?
So are you using a class 4 with your own cm data2ext script and in ext2 or ext4?
Serious.. It is mentioned several times before by Blay0. Even a fast card will work very slow with data2ext. Why do you even need data2ext? Are you a developed? If not app2ad should beer enough for you... NInge really needs data to be on as i they are not often changing system files..

easy man, i was just asking out of curiosity
i'm already using apps2ext and dont need data2ext, but it thought data2ext was slow on all card classes thats why i asked his setup just so i know
Hi,
Since this is a noob thread I'm feeling free to ask for help.
Somehow without any knowledge I've managed to Root my Legend, Flash roms numerous times, make my Legend S-Off, twig and play with different options like splash screen and all sorts of stuff that you need a bit or more of development knowledge. I'm a psychologist - I have no knowledge whatsoever.
Now that I've flashed ogo2's rom found here - http://forum.xda-developers.com/showthread.php?t=987251, I have cut down internal space to about 20MB+-.
I need help with this whole data2ext, ext2/ext4 and all the commands I've never met in earlier development stuff I've done to my Legend.
Where do I start? Is there anywhere I can read a noob guide for these issues?
Please help!
reupugi
edit: Oh I forgot - I have 8 GB class 4 card.
What help do you need? Understanding what it is and how it works? Or just setting it up.
Are you planning on using the data2ext found in my thread, or somewhere else?

Hi TGF,
I need help mainly with setting it up. I have no intention learning developing through trying here and there to implement different things others created.
My intention was to use the data2ext you created.
At the moment I've changed back to the nightly builds of CM7 (currently #153), since I had sync problems with ogo2's ROM. So I'm not so pressured space wise, but I'll still be glad to go through with the Data2ext.
Thanx,
reupugi
Ok, well the guide in the first post covers most of it, is there a specific bit you're stuck on?

It assumes I understand how to create ext2 or ext4, or to choose between the two. DO I have to backup my SD card when I create an ext2/4 partition?
Where do I use the commands in your post of data2ext?

You do need to backup your sd card, our you lose all your data. Rom manager has an option for creating ext partitions on your sd card, and I'd go for ext4, as it's safer. There's a section in that thread on upgrading from the ext2 version. Create your position with rom manager, then follow that section through. The commands can be executed on the phone using a terminal emulator, or from the pc using adb.

I'm not able to get the Internal SD card to mount after installing the pre-beta cyanogenmod 7. Is there some setting I'm missing or something that I need to do in particular?
Prior to install I was on the alien build and everything worked fine. Now when I go to the root directory using RootExplorer it says 'the sd card is not currently mounted'.
I've had my atrix for a while and i'm not a complete noob, just not an avid poster. Any help would be appreciated.
Edit: I have checked the storage menu and i do have 1.17GB of free space.
It can be found under /mnt/emmc. Unfortunately, I have to inform you for future reference that this is the wrong forum for such a question. Q and A exists for a reason, but I hope I helped.
Please post in the correct sections. Thread moved.

Thanks for the help. I found that but how do I get, for example, Rom Manager or other applications to recognize that location?
Mr Clown, My apologies for posting in the wrong section.

+1 wondering the same
i would also like to know, as i have only a class 1 microsd card and it creates wakeup lag. if i take it out, there is no wakeup lag but my phone wont recognize the internal storage.
I think it varies by application. Some will let you browse there and set it as a default directory for things, but many will not. I have just gotten used to having duplicates of random stuff for now :S I think it is pretty unfortunate, but it is what it is.
Maybe someone will develop something like this:

http://forum.cyanogenmod.com/topic/27030-questions-on-5gb-emmc-just-hacked-nc/
That's for the Nook, but I can't see why someone couldn't do that for the Atrix. However, I would imagine it won't be our own CM7 team because their task is to port CM7, and thus they are following the CM standards.
I have this problem too, i dont hae a external SD Card
im used to the internal 16 gb as my memory
now iwth CM7 , the phone is lost, browsr wont download, titanium wont find the sd card, nothing is working
so is an EXTERNAL sd card a pre-requisite for CM7, i never knew this..
and if so, what does CM7 do with the huge internal memory if it saves everything to the external (atleast thats where apps see it)
I want to give everyone a heads up about a series of fixes JC Sullins has created for CM7 running on the HP TouchPad. It is important that you go to his thread "CM7-fixes-for-sdcard-issues", in the rootzwiki/Touchpad forum and read the whole thing. I would post the direct link, but I don't have enough posts here yet to be allowed. Maybe one of the moderators can help out with that. I'm trying to spread the word about this important issue.
If you are having to move apps off onto your SD card because you are running out of internal memory, you have hit the 50+ app limit on your SD card, you are in serious trouble. JC also created a fix for something that is not working in CM7 called
fsck_msdos. This routine is supposed to check your SD card and fix any errors it finds. It turns out that the version in CM7 as released does not work. JC's fixes take care of that, the internal memory problems and the 50+ problem.
However, if you do nothing else, do his fsck fix and protect your SD card. Go read the thread and tell all your friends who are running CM7 or for that matter any Android rom cause they are all based on some version of CM7.
hi people!! im impressed one more time with the new rom 2.1.9!! but i have a question related to one of its new features which i dont understand very well... i hope some one has a little time to explain it with details to help me and other people who may have these same questions...
first of all whats partition and swap? i suppose partition is to take a part of ur sd card for aps and all this stuff, but swap?
second... i dont have any partition and i always move lots of aps to sd card without problem,then,why should i do a parition? is there any advantage in doing it?? in that case, is there a guide around here to do it in an easy way?
and finally.. swap! what is it for? is there advantages in doing it? in that case what are them and how could i do it in an easy way?
i hope some one could have a moment to explain it a little bit but please as clear as possible,taking into account im a full noob in this topic... and if anyone have more questions related to this topic post here if u want...
i would just like fully understanding all the functions, possibilities and goods of my x10 mini and this incredible rom...
thanks everybody who wants to help!!!
About swap and partition, actually I've tried it both, but it just makes my device slower (even on class 10 SD card)... Maybe, the explanation of this issue is because our phone already use up speed reading files and programs installed on SD card, so swap just makes it any harder...
I tried partitioning my sd card with swap file, using swapper, swapper2, but the best result is when I don''t partition my sd card at all..
Then, the next question perhaps : then why are there swap availability ? That I can't answer...

thx for ur answer!! at least u can talk from experience... the fact is that i feel my phone runs amazingly without these swap and partition things... but as u say, taking into account they are available i wanted to know if it would be even better for my phone to try them.
however watching ur results i will stay without swap and partitions, because i have all i need in my phone and still free space
thank u buddy!
I setup cm10.1 nightly on my fascinate and originally had ext2 + fat32 partitions. I was running into memory issues, so I went ahead and created a swap partition and was attempting to enable it. I probably found old/bad instructions and my phone lost a lot of programs. I would like to reset the phone with better partitioning and get the swap working properly. I read that CM can enable swap without installing any additional programs. Can someone walk me through the best way to setup swap. Also recommend sizes for my partitions. I presume fat32 will be the biggest followed by ext2 or should I go with ext3? then how large should I make the swap? Thank you for any help you can give me.

Swapping will cause tons of bugs, its better to stay without swapping at least till a good swao tool comes out.. I swapped memories in CM10
But i dont recommend anyone to do it even if he was in need for it.. U better wait for now
