FINALLY got cyanogen rom working. i've almost pulled my hair out over buying this phone(att user so i had to unlock and learn root, etc.)
anyways, got .999 installed and saw the * Apps2SD is automatic! All you need is a second partition (ext).
can someone point me in the right direction on how to do the partition part? i have full version of paragon and know how to use it but just don't want to fubar anything up.
i apologize for the noob question but i just need to know what to set my 2gb(although i have a 4gb class 6 in the mail now) sd card to what size partitions so i can run the add2sd.
thanks guys and love the site.

There is a sticky post in this section. I found it in less than 2 seconds. without searching.

Example for 8GB card.
Reboot and enter recovery (home+power) then go to console. Enter the below pressing "enter" after each line.
Code:
parted /dev/block/mmcblk0
print (to verfiy we know what size card we are dealing with. Mine was 8166 read below if yours is different)
rm 1 (if you had more than 1 partition you would want to rm them as well)
mkpartfs primary fat32 0 7622
mkpartfs primary ext2 7622 8134
mkpartfs primary linux-swap 8134 8166
quit
upgrade_fs
recovery
NOTE: this will reformat your entire card, so i suggest you back up your files.
and btw tell me the size of your sd card and i will type up the code for you...
use this method to tell me your exact size
go into recovery via home+power
go to console
pres enter
type:
parted /dev/block/mmcblk0
print
i am pretty sure you can see what number represent your total card size.

Easier Way!!!
OK,so I also have Paragon Partition Manager 9.0 Special Edition.
1.Go into your Paragon Partition Manager Software
2.Click on Partition Manager at the first screen
3.Click on your SD Card drive (ie. F:/)
4.Click on create partition in the left hand side of your screen.
5.It will ask you how big you would like your partition to be,then what type of partition. Paragon only supports EXT2 and EXT3 if your looking for an EXT partition. Paragon also only supports Linux-Swap2 and not Linux-Swap3.
If you need any more help man let me know.

well i wouldnt say ur way is easier... it does require using a computer, mine uses the phone.. and mine is simply typing what u see.

Also im pretty sure you need to use linux-swap and not linux-swap2
(i think 2 works but im not sure that its recommendable sicne the rom cookers themeselves use 1)
I would also use the method brian posted. its much more effective

thanks guys, i got adds2sd working and everything. on a 1gb right now until my new 4gb class 6 comes in this week.
i haven't done the swap things yet as i'm not sure of them just yet. i've learned quite a bit over the last week without trying to bug too many people on the forum. your replies are MUCH appreciated.
what is the different between ext 2/3 and linux-swap? i'm running my current 1gb 514mb fat32 and 445mb ext3.

ext3 has journaling which reduces corruption a lot. linux-swap is used as virtual memory.

thanks for the reply so in turn the swap will make the phone run faster right?
also, since no one answered my question in another thread:
although i'm running .999 when i press the camera button it open a box with a 'To:' entry and 3 button 'open', 'call', and 'send'.
i've looked in the settings to see if i can change what the camera button does(want it to open the camera like before obviously) without any luck..
any idea?

In theory swap should make it faster as it has more memory to play with.
For your other question, a file on the ROM containing the keymaps has been changed. The only way to change what the camera button does is pull it, edit it, and push it back.

Removing partitions on SD card

Alright so i have searched for quite some time and still cannot figure out how to remove the partitions of my SD card. I just want for it to be stock.
I created the partitions obviously with the linux-based android system so I can't undo this with my windows computer. Or at least I believe.
I have a 8 gb SanDisc and when I pull it up in SDFormatter V2.0, it says my card size is 6.90 gb. Is that correct???
Please point me in the right direction!!
Thanks in advance!!

If you created your partitions using Parted then you can also remove them this way.
From the recovery consol type:
Parted /dev/block/mmcblk0
rm 1
rm 2
if you have more then rm 3
Then type:
mkpartfs primary fat32 0 xxxx (xxxx being the size of your sdcard)
type quit and your done.
2 things, 1: I am assuming you used Parted to make them because you said you used the android os and 2: this is the wrong section for this.

And sorry about my post count I'm not a noob just got stumped by this.

but something more relevent, like a link from here.
and yeah rm in recovery console.
just use gparted. its the best and most simplest way to part ur sd.

Kudos 2 you bro and what section would this go in then?

windows would see the partition it just wouldnt know what it was so you just delete all partitions and create a new one.

btw windows has a built in partition manager,
control panel Administrative Tools then computer management and finally storage.

[Q] [Webtop] Next steps: More space or newer Ubuntu? (Poll effectively closed)

----- Announcements -----
The poll is now being treated as closed. As such, since I would be unlikely to look back after moving to a newer Ubuntu, and since the two efforts are effectively incompatible (unless I wanted to try my hand at flashing a new /osh which... no), I'm concluding that there are enough users who are happy enough staying on Ubuntu 9.04 that I'll work on the union filesystem first before moving on to newer versions of Ubuntu.
----- Your regularly scheduled post below. -----
I believe I'm getting close to having a reasonable "first pass" of having a working Ubuntu on the Atrix. The interesting question becomes: what next? There are two steps I can see right now:
Get a FUSE kernel module working so that we can get a union mount for our modified Linux so that we can have more effective space. Note: this process is almost guaranteed not to work with the next option.
Now that source code is available for the Ubuntu files (I need to find out if we have everything we need, mind you), port newer releases of Ubuntu (starting with either 9.10 or 10.04).
Users, what would you like to see? The numbers at "closing" were 48/47/3.

i think it would be cool to see a 10.04 ubuntu - but what can be done with that without very much effective space? if you could find a way to expand the storage with an ubuntu port (even if it's after you port ubuntu, then find a way to increase storage) i think that makes more sense than trying to improve the inherently crippled current webtop setup

It would be great to see more storage! That is the biggest limitation at this point..

im all for 10.04 or 10.10

Wouldn't you require more space for this though?

Not really. Remember that the 1 GB filesystem file is a copy of the partition that Motorola ships. Upgrading would be swapping out Ubuntu 9.04 packages for Ubuntu x.yy packages, so it would be a matter of trading space, not strictly losing it.

Forgive my stupidity but... you are reffering to the 1gb file called Ubuntu.disk right?
Meaning, I can move that to SD to leave more space internally?

I'm pointing out that ubuntu.disk is 1 GB, but once it's created, it has no reliance on /osh. So as long as the Ubuntu x.yy installation is < 1 GB like the current 9.04 installation is, the space issue won't get any worse. No better, though.
And, no, moving ubuntu.disk to /mnt/sdcard won't work. If it did, I would have created a partition on the SD card to start with.

NUKE webtop and make it run ubuntu Pure ubuntu with the option to show it on the atrix screen too HEHE !

union mount! Also I bet this has non-ubuntu implications (internal and sd card as 1 mount point would be hot). Also why do we need a newer version other than to say "i have ubuntu x now which version number is greater than y was". What features are there in 10 over 9?

You're asking somebody who's typing this from IE9, so I can't help you there. But, interest seems high, and it is true that newer software isn't available as easily for older versions of the operating system.

Would it be possible to move it to SD card if there was an ext2 partition there? For example, on my 16gb SD card, have a 14gb fat32 partition, then a 2gb ext2 partition, with your mod mounting the latter instead of a file on /data.
I started playing with this idea yesterday, but ran out of time before I got it to mount properly in Android... Do you think it's feasible?

Ah I see... What about symlinking a whole lot of stuff over to /cache, since it's a 600mb partition doing not much? I'm guessing you've probably tried that avenue too?

No, actually, since the initial idea didn't involve use FUSE to be able to do crazy filesystem tricks. I thought /cache was needed, though? If we can find space here and there, it might be possible to decrease the footprint in /data a bit so that people aren't squeezed so tightly on space.

/cache is only used for temp downloads (market apk installs, email attachment previews, etc) and OTA updates. The temp downloads don't take up much space - less than 50mb usually, but the OTA updates would probably be a a bit bigger. But who uses those right?
I'm one of those greedy people who have over 1gb of junk on their /data partition

[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,
JMG

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.

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.

Ext partition

Ok this might be a noob question but im going to ask it anyway..
Whats the point of creating one on the sd card?
Is the only benefit that i can move my apps to the sdcard with tools like link2sd?
Or can i also let the phone think i have more internal memory?
Im running the jellybam rom but i cant find any info about ext partitions, anyone who can explain it to me?
Thanks and enjoy your weekend guys

I don't know that there is an advantage for ext3 with a flash drive or SD card. See:
http://www.phoronix.com/scan.php?page=article&item=linux_f2fs_exfat&num=1
The article is mostly about f2fs vs exFAT, but some comments included.
"Earlier Phoronix tests have shown that F2FS from flash storage is already generally competitive with the popular Btrfs and EXT4 Linux file-systems."
"Seeing a user-space implementation of the Microsoft file-system outperforming the in-kernel "Flash-Friendly File-System" came as a shock."
With already slow SD transfer rates due to the media itself, I doubt you'll see an improvement in system performance. Maybe someone here has a better idea. I don't. But the worst you can do is nothing.
My only concern would be hooking up the 970 to a Windows machine; "stock", Windows may not see the extra ext2/3 partition. You'd need Linux to do that.

Hmm i've readed the article but cant find any info about what im looking for..
Anyone else who can help me?
