From a thread at XDA Dev.....I think you want these two commands if you already have an ext3 and just want to upgrade to ext4.

Original thread: http://forum.xda-developers.com/showthread.php?t=534714

tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p2
e2fsck -fpDC0 /dev/block/mmcblk0p2

I had trouble getting e2fsck to run. It obviously doesn't want to run with it mounted, and I couldn't get it to work in the recovery console. But I think on Cyanogen's roms it gets run automatically at boot anyway.

I also run cyan 4.0.4 and just tried this on my ext3 apps partition. It worked fine after just running the first command and a reboot.

For the record the easiest way to go from ext3 to ext4 is through the RA 1.2.3 recovery. From the alt x console just type utility and pick option 1, not that I want or need an ext4 partition.

Is upgrading going to wipe my apps?

To get a new rcovery image i just download flashrec and use Ra 1.2.3?

No it doesn't wipe your apps.
Download it, put it on your sd card and from the terminal console type.
1 su enter
2. flash_image recovery /sdcard/recovery-RA-dream-v1.2.3.img
3. reboot recovery
And that should put you in the RA 1.2.3 recovery. My other post tells how to upgrade to ext4.

is there any advantage to having ext4 over 3?
