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

[epidenimus]

I have been using this mod now for more than a year, was one of the original people to get it up and running for reborn and then drew's cm7. I have done this and yes those apps would stop but all you need to do to was insert sd card & reboot phone. If needed in terminal re-enter data2ext--enable

And what if the SD card fails or he upgrades it? Most folks don't just pull out the SD card for fun. The device does become dependent on the SD card to function after this mod is applied; I think that's what he was getting at.

I rather prefer the Dark Tremors approach found in OptiROM if you are looking at this.

If the sd card fails or he up grades just enter in terminal data2ext--disable and it returns it to stock set up. Sd card will still be partition of course.
I do also keep a pre- data2ext nandroid so if the card fails or for some reason I stop using it I have a backup of apps in original position.
So if the card fails its never a big deal (never had a card fail), but I have pulled sd card out to see what happens.
I actually used this set up on opti-rom too instead of the dark tremors.

Anyone tested data2ext with CM9?

Without a working Market, there isn't much use for the mod.

Using alpha 2 I have tried enabling data2ext with no success. Anyone having any luck?

If you have tried these instructions on another ROM let me know and I will update the list of what works and what doesn't.

confirmed for hydroRom(on zvj),i used the cm7 zip and instructions

I used it on GingerRom, but I had to copy e2fsck and tune2fs to /system/bin and 6 libext*.so files into /system/lib in the rom before I could format. Then I copied 40data2ext to the init.d folder, rebooted and enabled the data2ext. I probably didn't need to copy 40data2ext, it could have been flashed.

It seems after installing this mod when trying to install apps via "adb install" command from a computer the phone crashes and reboots itself. Any way to prevent this from happening?

nevermind was just the particular apps i was trying to install i guess.....

Ok, I've been using data2ext for months (maybe a year actually...) now on this Optimus S and I've been using this /dalvik-cache ever since I first had a 'Low on space' issue and found this thread. However, I've recently re-flashed the ROM on my phone and for some reason while trying to restore my apps from Titanium Backup, I've been running into this 'Low on space' issue again. I know that I have enough free space since I actually checked:

/data shows as having 59% used and /cache shows as having only 29% used. So I don't know what the issue is. Also, I'm wondering why a couple of my programs (Aldiko ebook reader and Scrabble Free) have created their own mount points. Is that normal or is there some issue that I don't know about. I would greatly appreciate it if I could get some help with this issue. Thanks ^_^

How can I tell which class is my 8gb sdcard? After I do this will I be able to disable or enable? I ask this because I change roms a lot

it's on your sd card. (there should be a large number with a circle around it. (So this is a class 2, because there is a two in the top right corner.

Some of the cheaper cards do not have it posted. So you will not see the 2,4,6,10 ect...!
If it not shown get a new card!

Yes you can disable it!
just type data2ext --disable in adb or terminal.

Just FYI if you flash a rom that does not support it nothing bad will happen even if you left it enabled. You just wont see the extra space.

First which rom are you trying to use this with? Second did you use the correct data2ext.zip for the rom your using?
If your running CM7 then use the : data2ext4-V4.zip.
Make sure you flash the zip first before you enter code.

4.Boot into recovery and flash the data2ext zip.

5.Reboot into the ROM and make sure SD-EXT is not mounted. From ADB shell run


Code:
mount|egrep mmcblk0p2
If that command returns anything unmount SD-EXT by running


Code:
umount /dev/block/mmcblk0p2
6.Format the ext partition by running these commands from ADB shell:


Code:
mke2fs -m0 -b4096 /dev/block/mmcblk0p2
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p2
e2fsck -yf /dev/block/mmcblk0p2
tune2fs -o journal_data_writeback /dev/block/mmcblk0p2
tune2fs -O ^has_journal /dev/block/mmcblk0p2

7.Activate data2ext by running this from ADB shell. Reborn/VD based ROMs will see some errors about modules already being loaded


Code:
data2ext --enable

Yea give the rest a try, you might be getting that because it might already be unmounted.
