[Q] F2FS question

I'm sorry if this has been asked, but I have looked and am not able to post in the developer thread yet. I've got everything up and running on my N7 with f2fs, but I'm curious now if I update my ROM do I have to go through all the steps again? Do I always need to format data at the end and lose everything? Should I be using titanium backup to solve this? Hopefully someone can help me out.

If everything is up and running on F2FS already, you can flash and restore titanium backups as normal. You just now have to make sure the ROM and/or kernel you're flashing supports F2FS or has been converted to support F2FS.

I am already on Carbon Rom All-F2FS, should I switch to another F2FS rom, what wipes are necessary? And should I format my tab again to all F2FS?

Just do a normal clean flash like you would if you were still on ext4. No need to reformat. That's how i switched to Carbon. As far as nightlies on Carbon (or others), just dirty flash them. I've had no problems doing that.

My attempt to convert a XT1033 converted to GPe to F2FS.

Hello folks,
Well, we all know that the stock Moto G filesystem is F2FS. But surprisingly, the Moto G GPe has a native Ext4 support. Since F2FS is supposed to have about a 30% better performance, I decided to try out the convert to F2FS feature in Philz recovery. So I formatted my system and cache to F2FS (since it didn't give me an option to wipe data and data/media to convert) and flashed a ROM. Currently, I seem to be facing a bootloop.
Anyway, has anyone else tried something like this? If yes, then please share your experience here.
Cheers.

It would be great if that would be possible,then you could jump from retail stock to GPe more easly. I have an XT1032 stock rom and i'd really like GPe,but my concerns are that would i be able to stock XT1032 again from GPe? You know,for F2FS and if i wanted to flash custom roms again to have better support. Any thoughts on my question? And look the first post,this is really interesting since if you'd want custom roms and you are on GPe,you wouldnt need to flash stock ROM to avoid bugs with custom roms and GPe

TWRP also include a format to f2fs <-> ext4 option:
Add GUI option to change or repair file systems on individual partitions. The change is destructive so backup your data including internal sdcard first. This option should make it a little easier to migrate a device from ext4 -> f2fs, for instance. You will find this option under Wipe -> Advanced Wipe, then select only one partition and then press the Repair or Change File System button. If a developer has added f2fs support for your device and we don't have it in TWRP, please contact me via PM to arrange for it to be added.

U need a kernel support somewhat like this in nexus 5 for f2fs
http://forum.xda-developers.com/google-nexus-5/orig-development/nexus-5-f2fs-t2668486

Stock kernel supports f2fs, GPE kernel does not. Development of a GPE kernel that supported f2fs would be ideal, assuming the GPE stock ROM also functions correctly with a f2fs formated USERDATA partition.

Has anyone even tried to flash boot.img from stock,and then converting in philz?

/boot/ (kernel+ramdisk) does not need to be formatted. Flashing boot.img before or after wouldn't make any difference.

Well, I tried using TWRP, but it ended converting my phone back to dual sim.

Using TWRP to reformat 'data' from f2fs to ext4 wipes SDCARD and didn't even change the format. Right now it appears if you plan on moving between GPE and non-GPE and possibly back again, keep a full firmware image for both.
EDIT: Actually it appears TWRP did format correctly. But the GPE kernel can't get past the Bootloader. Perhaps there are other partition table differences.
After another try..the following works fine.
Migrate to GPE:
1) In TWRP, wipe, and format 'Data' from f2fs to ext4 (this will wipe internal storage.)
2) Sideload / adb push GPE ROM or flash ROM and Kernel via fastboot.
3) Reboot​
Return to Motorola Stock:
1) In TWRP, wipe, and format 'Data' from ext4 to f2fs (this will wipe internal storage.)
2) Sideload / adb push Stock ROM or flash ROM and Kernel via fastboot.
3) Reboot​

I re-read your OP. The GPE Kernel expects the 'userdata' partition to be ext4. Unless someone develops a custom kernel to support it; you will never be able to run the GPE ROM with an f2fs 'userdata.'

Because you set all partitions to F2FS. Only need to change /data to F2FS. Leave system and cache ext4. You would need a ROM with a patched fstab and then a kernel supporting f2fs for system and cache to be in F2FS as well. Plus major benefit is in /data, not system and cache. I tested full F2FS on my N4 and it was more a pain with less gain. /data is all that should be F2FS.

You can get it by deleting the partition / data and change it later by f2fs with TWRP fastboot erase boot partition and flash the boot.img from the stock 4.4.4 rom motorola everything from GPE and I have it so it shows more fluid

F2FS - recovery not compatible?

I was trying to convert my system, data and cache to F2FS but after the conversion I can't use Data anymore (apparently it cannot mount data and system anymore).
Could be a problem LinkedIn to the grarak modded 3.0.2 I'm using for Exodus 6?
Any feedback is welcome!

Up

Most probably as the official one from twrp supports f2fs natively.
I would recommend to go back to official twrp convert to f2fs properly from there and then flash the modified one, do this if you are brave enough, i havent tried this method but it should work. If all fails stay on ext4 till garak or twrp updates their twrp versions.

Thanks for you answer... I thought the same... I'll try as the new phone will come and let you know...

F2FS + stock rom

As the title said.
Is there any way to use stock rom(pie) with f2fs data & cache partition???
I tried flashing custom kernel, but no luck.

I think rom must support f2fs, not only kernel. And if u want to use f2fs try custom roms there are lots of roms for our device which support f2fs
