    I have a rooted Optimus with a stock rom. No desire (at this point) to change the rom or kernel.

    However, I would like to be able to mount ext2 and/or ext3 partitions to take advantage of Titanium Backup's new feature that lets you move apps & data to an ext2/3 partition on the sdcard.

    Is there any way to get this to work without changing the rom/kernel? The release notes for link2sd (another app that will move applications to the SDcard) implies that all it takes is an ext2.ko or ext3.ko shared library. Is this correct, and if so, where can I find this library?

    Here is my set of extfs loadable kernel modules for Optimus V with stock system. Contains ext2, ext3 (requires mbcache and jbd), and ext4 (requires mbcache and jbd2; untested except for load/unload ability).

    Remove the .zip file extension (it's not a zip file, but this forum requires that suffix). Untar the entire 2.6.32.9 subdirectory into /system/lib/modules. With the included module* files, modprobe resolves the necessary dependencies. Assumes you already have busybox installed for access to tar/gzip, modprobe.

    This code is open source (GPL); built from unmodified source code obtained from the LG web site (model LGVM670).

    (No warranty or liability for data loss assumed; use at your own risk and back up all important data first. If you don't know what this is, or what to do with it, you probably shouldn't try to use it.)

    without flashing a new rom you could flash a new kernel... a few options available which give you ext support (among other things like overclocking)

    Hey larrycl, If your rooted do you have an all important custom recovery installed that allowed you to make a backup of your system in case of a OOPS! If so it should have an option to partition the sd card.

    Without flashing a kernal or Rom you can't use anything else other than fat32. I would just use link2sd. And yes get a custom recovery and make a backup.

    Behind you
    You need to install a custom kernel for ext* support.
