ext filesytem conversion optimus s

[ikeywatson]

is there anyone who knows about file system conversion.
what processes does it involve.can it be done ?

Relative to Android, I can tell you that the ROM and recovery both need to be able to handle whatever your FS of choice is (the kernel modules must be included). As far as I know, all of the parts for the Optimus S are built for YAFFS, so it would be difficult. Are you thinking about converting the internals to EXT4?

 

[ikeywatson]

yeah but i dont have the know how,like i said my moment had the abilty thru kernels and recovery (cwm)and the roms where able to support rfs/ext2,3,4.our phones should be able to do it.does cm7 roms and kernels support ext?

When you do all of the steps in installing data2ext, you're converting your ext partition to journalized ext4

 

[epidenimus]

What exactly are you looking to do anyway?

He's looking to convert the internal filesystem to ext4, not the sdcard ext partition. Data2Ext has nothing to do with it.

i personally like the feature because it is a faster file system,and it grew on me while i was using my moment(which i switch over too time to time )i thought it would be cool to have it as an option.

Oh... well.... I'm not sure that's a good idea. Yaffs is a much more stable fs. It doesn't corrupt files the way the ext series will. And it has much higher performance. Data integrity was the primary concern in development, with a higher performance a very close secondary.

maybe just me but i think that it is a dependable filesystem,our phone is based on linux and it is/has ext file system,if i could do it i would,if some one can get it up i will test it

This will be my last effort to talk you out of this.
YAFFS - Wikipedia, the free encyclopedia

That being said, there have been times in my life where I said "I wonder what will happen if I...". I, too, like to tinker around and see if I can pull a "Tim "The Toolman" Taylor". Good luck!

Well if you're on it, why not go BTRFS? Several distros are going that way for the sake of speed.

Android is very specific with filesystems. Not sure if you can use BTRFS yet, but I think last time I was in the kernel build configuration there was no option to enable it. Also some distributions caution you against BTRFS since it's not an entirely stable filesystem yet and apparently lacking some features found in EXT3/EXT4. (it's been a couple months since I've looked at BTRFS though.)

But really I'm not sure how much of a performance boost Android would really get from switching filesystems (I compared BTRFS and EXT4 in MeeGo and I didn't notice that big of a difference really)

Sorry lol, its seems I ended up writing a small wall of text again. I'm horrible about that...

Walls of text are encouraged, as long as they're informative.
