[How-To] data2ext for Reborn, Froyo 2.2 and CM7

You may need to change the block size (4096) to be optimal for the partition size you choose. This is in the 5 terminal commands used to format the partition.

Still use swap 0?
I couldn't Get past the first terminal command.it said the block wasn't there?

Yes, still use swap 0.

I'm not quite sure where you are having problems. The first terminal command is making sure that the sd-ext partition is not mounted. It should return nothing if you just created the partition and have not done anything with app2sd stuff.

Code:

mount|egrep mmcblk0p2

You only need to run the second command if the first command returned something indicating that the sd-ext partition on your memory card has been mounted.

Code:

umount /dev/block/mmcblk0p2

If the first command formatting gives you that error, then try partitioning it in recovery again.

Code:

mke2fs -m0 -b4096 /dev/block/mmcblk0p2

If that still gives you problems just run the mount command and copy the output into a post here so I can see what is going on.

Code:

mount

So if /data is linked to the sd card, then what, if anything still uses the 165mb of internal storage? Is it just wasted? I have a class 10sd card but internal has got to be faster...doesn't it?

I get this message: It seemed to work at first, then I started moving my apps back from the sd card (with app2sd app) and once I was almost done with about 400mb free my phone said it was too low on memory to move any more apps back over. I rebooted and data2ext was no longer working.

data2ext --enable
insmod: can't insert '/system/lib/modules/mbcache.ko': File exists
insmod: can't insert '/system/lib/modules/jbd2.ko': File exists
insmod: can't insert '/system/lib/modules/ext4.ko': File exists
Data2EXT is already enabled but not active...

You don't need to use apps2sd...

**nomad85** · 11-04-2011, 10:09 PM

thats why I was moving all my apps back over. I used to use it before I did the mod.

Hi to all,
I'm trying to install data2ext script but it does'nt work... I think that problem is ROM version, how can I understand witch rom is installed in my mobile?

**Masterjakeway** · 11-14-2011, 09:05 AM

Settings/about phone will tell you. But, it won't exactly spell it out. Or, maybe it will. Under mod version

**charmon1605** · 11-17-2011, 04:30 AM

I running Kravens CM7 ROM, and Xionia recovery. I followed all the commands in the 1st post and everything seemed to go fine. No errors.

I was expecting to have more space in my phone's memory. But there isn't any extra space.

That's what this is supposed to do, right? If so, any ideas on what could be going on with my phone?

**Masterjakeway** · 11-17-2011, 04:54 AM

What happened when you did data2ext --enable?

**farbeh** · 11-20-2011, 07:53 AM

Hello,
I followed the installation for my optimus S and all went well until data2ext -enable. It said it cannot find data2ext !
Any ideas?

**Masterjakeway** · 11-20-2011, 12:13 PM

Something didn't flash or run properly. Start over at the beginning...

**farbeh** · 11-20-2011, 10:26 PM

Hello MasterJake,
I am using the Your MOM ROMso maybe I am missing a step. But I still am unable to activate data2ext. See attached CMD stream.
This is after formatting and partitioning the SDCARD.
Thanks for your comments.

**Masterjakeway** · 11-21-2011, 01:32 AM

Did you flash the zip?

**farbeh** · 11-21-2011, 06:29 AM

Yes, the data2ext that is on the installation instruction.

**Masterjakeway** · 11-21-2011, 09:57 AM

Maybe try re flashing?

did you partition the sd card for ext,that could be the case

**Masterjakeway** · 11-21-2011, 12:53 PM

Yeah, make sure to partition using recovery.
What recovery are you using, btw?

**farbeh** · 11-23-2011, 06:44 AM

Yup partitioned fine , used the recovery that come with MOM ROM, zvhrec. HAve reflashed a couple of time. Cleaned everything on the SDcard except the data2ext on MOMROM installation page. Then partitioned in recovery. Then ran some formatting script I believe.

Confounded !

**hamagc** · 11-29-2011, 07:12 PM

Don't know where else to put this so I figured here. I am a big supporter of data2ext and have been using it since I can remember. Often when I drop my phone it kills data2ext I assume from the sdcard moving in the phone. I fix this with the e2fsck command in the op. Fixes most of my data2ext issues. Just an fyi.

What would be the proper procedure when upgrading from one CM7 rom to a newer version of the same rom? I've got data2ext working great on thekraven's 11-20 build, would like to flash his 12-6 build.

Thanks in advance!

Caveat: I have switched roms, but I have not upgraded since installing data2ext. So take this with a grain of salt (or a nandroid backup is always useful)

I believe all you have to do after an upgrade is flash data2ext and run data2ext -enable again.

If you want to move the dalvik-cache to the SDEXT you would need to follow those procedures also.
