[Q] noob question - created ext4 partition on SD, but how to use it?

Hi,
I've created an ext4 partition on my SD with the intention of using it to store apps on
I used the gparted method described in http://forum.xda-developers.com/showthread.php?t=1016084
Now I've flashed a couple of ROM's (Oxygen, Redux and CM7) but have no idea how I can put apps on it
Additional question:
1) if you do a data, cache/dalvik wipe will the apps on the ext4 partition also be deleted or will they remain on it so you can reuse them in another ROM
2) I've rooted and s-offed my stock rom, can I use the partition I've created here as well? and if so, how?
thx

on all 3 roms youve mentioned you tried, app2sd is automstically setup on rom install. so you are already using app2sd.
1. yes if you wipe dsata, it wipes your apps on ext 4 partition
2. and yes, your aready using your partition once your using a app2sd rom. specific roms allow you to push your dalvik cache to your partition but it is not reccommended as it can slow donw your phone.

hi,
thx for the feedback, can I install app2sd on my stock froyo rom somehow?
I'm rooted and s-offed

extra test: I've installed Leedroid with app2sd
when I install an app from the market my internal memory decreases and I cannot move it to SD card
I've created a 500mb partition, should this be visible as "internal memory"?
cheers

Some apps still need some space from the NAND internal memory.

Nope. But if you download "Quick system info" from the market, you will see where it's written A2SD your external partition and its used space.

If you are like me and want to install lots of apps app2sd is not good enough sorry I was on Leedroid superb ROM but I soon ran out of install memory because even if you move app2sd say you have 20mb app and move it to SD it will move like 16mb to SD and 4mb will still be on phone.
Best way is Data2SD I use startburst and have 2gb ext4 and my phone thinks it has 2gb internal memory
Make sure you backup and have a SD card class 4 and above some say class 2 fine I dont think so.

EXT4 SD card partition not appearing or working

Hi,
I have upgraded from 2.3.7 to a JB MOD. I prepared my SD card in gparted with a 500mb FAT32 and the rest as EXT4. I have inserted the SD card and 'setting\storage' only sees the in built 150MB EXT and the 500MB FAT32 on the SD Card but no 3GB EXT4 partition. In terminal I ran a2sd install and on the reboot it said 'optimising' apps and I thought it was moving apps. However, when I install apps from the store they are installed on the in built RAM.
Using app2sd I can't move any apps I used to be able to on 2.3.7.
Can someone please advise?
Thanks
Paul

Here is your most likely scenario because it happened to me: If you created your partition on a PC, for some reason it doesn't work properly (well at least in my case). Then the phone doesn't read the SD card properly. What you should do is upgrade clockswork mod recovery on your phone to the most recent version and create the EXT version using the recovery console by booting into recovery.

Hi,
thanks for the reply. I'll see what version I have. It is probably old as it is 15 months since I did the CM 7 install to my phone.
Paul

it should be 500mb ext4 and the rest fat 32, also 1gb ext4 is recommended and dont use ClockWorkMod recovery to partition sdcard, use 4ext recovery instead. CWM makes bad partitions

Is there a specific way around?

Hi,
I read the FAT32 should be first and the EXT4 the rest. Is that correct?

I've redone my card (3GB FAT32/500MB EXT4) but my in built memory seems to run out of space for apps quickly. I thought the SD-Card EXT4 partition was supposed to add more space for apps to the phone.
Is this not true?

what JB did u install? theres acouple i think that u have to activate the a2sd by doing the following in terminal emulator
su
a2sd install

Hi,
I am using Elk759 JB ROM. I did run the a2sd in terminal after redoing the partitions. It reboots and says optimising apps 1/...79 (whatever number). I can't tell if it has moved anything onto the EXT4 partition of my SD card.
I will boot into a live linux and take a look on that partition.
If it isn't working is there anything I can do?
Thanks
Paul

That seems to have worked as I've installed loads of apps and it hasn't complained about space.
Thanks for all your help.

Running data2sd in cm 10

Hey guys, I recently flashed benjamingwynn's cm 10. I really liked the rom but the rom takes up a lot of space. My internal memory is very low, so even if I use link2sd I was only able to install some apps. Then I tried data2sd from the market. I created a storage file but when I try to mount it, there's nothing happening. Is there any way to make data2sd working? Should I follow any other steps?
Thanks in advance!

Data2sd from market? lol.
Data2sd is a script which is only flashed by installing from recovery or rom manager... Get cronmod int2ext+ script and flash it from recovery. It works pretty well.

I can only repeat sukhjit321, you have to flash it in recovery.
Download this: http://www.mediafire.com/?t1r06j60gybhn2t
Put it on your SD card, then install it from recovery just like a rom (delete cache partition and dalvik cache before).
Or try int2ext+ or something else, but you have to flash all of them in the recovery.

Yes, first make a FAT32 partition, and then an ext4 partition (the ext4 is going to be your internal memory, so make it as big as you want)

Hi....i have a Wildfire S working on CM10. Im facing the problems of Low internal memory too...I have tried usinbg Link2Sd but barely helps...again doomed for low internal memory...if i flash data2sd try int2ext+ or something else, i wud have to flash all of them in the recovery by going in recovery mode and the install from SD card..BUT do i have to wipe everything or what i mean to say is do i have to flash the CM10 all over again by deleting everything OR just flashing DATA2SD / int2ext+ wud help.
Beacuse while using Link 2Sd i have already created partiion EXT4 for about 3GB on my 8 GB SD card..
Please suggest how i must do the process ....
Regards ,
Piyush

no...don't flash data2s or int2ext or othe sceipt simultanuslly....lit will cause crash...and u can use your link2sd partition as 2 nd partition....but if after flashing int2ext+ your internal memory dont change and 150 mb than you have to make patition again...sad..

Installing CM7 with m2sd

I'm trying to install m2sd on cm7. I do a full wipe, install the Rom, gapps, and m2sd script. After starting up I enable m2sd for apps and reboot. Then I start installing software, but they take up space on internal memory. After moving them to sd they don't go to ext partition but to the fat one.
What could be the issue?

how did you partition you sd card? should be done with gparted (step 5 here) or 4ext recovery only (not minitool or clockworkmod recovery).
depending on the options chosen for m2sd, some stuff will still take space on internal, for instance app data is best left on internal for performance. use an app like 'diskusage' to browse all your partitions.
make sure you're also s-off and on cm7r2 hboot to maximise space (have a look for further guides if this doesnt make sense).

Try also enabling dalvik cache to sd.

Or the data + r-mount combination (which is I'm using now with no problem at all).

I just did it all again, to make sure I used gParted, so I'm sure I have 10gig Fat32, 4gig EXT4 and 256meg Swap. Then I did a full wipe of the phone, installed cm7, gapps, and when the system booted I installed and configured m2sd APK and rebooted. Still, in the gui section you can see "File System Type: N/A". It looks like it didn't recognise the FS but I have tried setting that to auto and EXT4
EDIT
Does anyone know what a2sd script has been used in THIS rom?

follow the guide again...
4gb ext4 partition is too much, you won't even need that much for apps! absolute maximum that i've read you should use is 2gb, personally i recommend 1.5gb.
you also don't need swap.
both partitions also need to be primary as per the guide.

that rom uses terminal emulator to enable A2SD. follow the guides/instructions in that thread.

[Q] Internal memory and sd ext

hello guys
im using CyanoMod007 (CM10.1.2 | JB 4.2.2 | A2Ext+) [STOCK | CM7] [v31 | 07/08/13] rom and i have a problem.
i though my apps would go in the 1gb sd ext partition i created, intead i have my internal memory with 148mb almost full. what have i done wrong?

How did you partition your sdcard? Should be done with 4EXT recovery or gparted only, not minitool or clockworkmod recovery
Your internal memory will read 148mb because you're still on stock hboot.
You can increase it slightly by changing to cm7 hboot (requires s-off) and installing the cm7 version if the ROM.
However your internal memory still won't read 'internal + sd-ext'. You may need to activate a2sd using terminal commands, should be in the ROM op or search the thread.
Move apps and dalvik to sd-ext, most of the time you need to keep apps on internal to trick them to sd-ext (do not 'move to sd')
Finally check all your partitions by installing DiskUsage app and see how your /sd-ext and /data (internal memory) is filling up, understand HOW your memory is being used

tnks for your reply mate...
im still new to all this, what i can tell you is that i used 4ext to partition the card and then recovered a backup i had. its s-off.

Before you do anything, install DiskUsage as advised.
- Browse to your /sd-ext partition, you may need to enable root permissions. If it's not filling up with your apps then you haven't activated A2SD.
- Browse to your /system partition, you'll find that you have a lot of free space here as you are still on stock hboot. This is effectively wasted space. If you change hboot you'll have a smaller /system and therefore larger /data (internal memory) :good:
So like I said, if you want app space, change to CM7r2 hboot using fastboot commands (search for a guide), full wipe and install the ROM again.
Follow the instructions as written in the first post to activate A2SD. Recommend you choose to move dalvik cache only to sd-ext.
