People around i9300 kernel developement backported F2FS and managed to boot modified omnirom.
Should I bring this stuff to upstream?

f2fs for external SD cards: Sure
f2fs for /data - Not until the next Android revision, you can put all the infrastructure there, but changing from ext4 to f2fs would require wiping /data

Wiping is okay.
We can try f2fs on /system, it gets formatted each time anyway. I know it won't give us massive performance boost, but it will be nice start point for now.
Why we can't use f2fs on /data?
Moto X has it already.
PS: can I use debian's arm binaries in recovery? Specifically f2fs tools.

Because /data is currently ext4 on the device you specified initially, and you can't change filesystems without wiping. Making users wipe at this point in the 4.4 cycle is NOT OK.
Not much if any benefit of f2fs on /system - Moto G doesn't even use f2fs for /system (it does for /data)

Anythng else? Will it work as intended if I will just patch kernel, patch device, format.
I remember Dees_Troy mentioned /data/media trickery may not work.
I am using DualBoot and currently have 2 ROMs both with EXT4 system.
I would like to flash latest DJNoXDs Slim ROM 4.4.4. with F2FS and to keep CM ROM with EXT4 system.
Does anybody know is it possible to flash 2 ROMS, one with EXT4 and other with F2FS, on one O2X device by using DualBoot?
Tnx.
Hi,
I have installed custom ROM and apparently it converted my userdata partition to F2FS, because when I try to install any other ROM it fails after checking userdata filesystem type. TWRP doesn't boot as well, I only have CM recovery working. I'm looking for someone who can help me write updater script to format the partition back to ext4 using mkfs.ext4 which is included in recovery. Please help.
Installing custom TWRP with f2fs support from here helped.
Hi, wouldn't it be sufficient to switch to a custom kernel with f2fs driver to be able to run MIUI with a f2fs file system? It is even possible? With LineageOS you still cannot use f2fs on the /system partition (maybe in the initial ramdisk there is no f2fs driver ?) but at least /data and /cache partition, also on MIUI. Is there a way to do that?
I'm trying without success, installed a custom kernel which claims to have f2fs support, formatted the cache partition in f2fs to do some testing, typed the 'df' command in the linux shell but no cache partition is displayed.
Using f2fs on the /system isn't a good idea to begin with, the /system is a read only partition so you wouldn't benefit from anything that f2fs gives.
Hi,
I made this guideline for those who want to convert filesystem from EXT3 / EXT4 to F2FS on lavendar, for amazing speed & performance.
I already had MIUI EU beta working on my phone.
Note: Internal data storage will be wiped. Make sure to have a backup.
Steps:
1. Install Orange Fox Recovery (latest one)
2. Reboot to recovery
3. Go to Manage Partition
4. Select "Cache" and click orange tick button, then choose F2FS as the file
system and proceed.
5. Again, select "Data" and click orange tick button, then choose F2FS as the file
system and proceed.
6. Reboot to Recovery again.
7. Install a custom kernel which support F2FS (i.e Evira)
8. Install Universal F2FS support patch file. (otherwise causing boot loop)
9. Reboot
Enjoy the speed.>>>>>>>>>>>
Hi! Filesystem F2FS keeps always even if you make full wipes + format data? For example, if i do the process but later i want to change my device's ROM, system will still have F2FS after wipes and format data? Sorry i've never changed my device's Kernel so i don't know if the system keep the new kernel (and the F2FS support patch file mentioned in this post) after a wipe + format data or they have to be re-flashed. Thank you in advance.
Did as instructed. got a boot loop : (
Are you sure that fstab flags are properly set? I don't see 'nofail' option or maybe there's some other option that substitutes?
I use miui eu 9.8.9
I reformatted back to EXT4 and it boots again.
If you are not so sure (neither am I, I will go research mount command options) then I recommend 3 separate zips
One that's F2FS only for cache and data
One that's all EXT4 for cache and data in case someone needed to revert without reflashing rom
And one that's F2FS cache and EXT4 data because migrating data partition can be a lengthy process for some people. But formatting cache is always easy.

I had the same problem, to solve it do the partitions process, flash first evira, reboot to recovery again and flash the patch. It worked for me and booted succesfully into the rom. I use xiaomi eu 9.8.9 too.

So I do it like this?
1- change partition fs
2- reboot into recovery
3- flash evira
4- reboot into recovery
5- flash fstab.zip
6- reboot into rom
Is there actually any benefit at all in using F2FS on Lavender since the flash type is not one of ones supported by F2FS?

What do you mean when you say that its flash type is not supported by F2FS?

See, F2FS works on NAND flash memories.... Lavender ilis NOT a NAND flash, so there is no advantage in using it. At least this is the rationale if I am not wrong.
As speed goes, F2FS is no benefit as your link said, but also for the wear and tear there is not much benefit

Hmm? according to mi website and wikipedia it uses eMMC 5.1 which is a NAND storage. why wouldn't it work?
As for my link they all agree that F2FS is a bit slower for read but hellalot faster for write. overall gain is considerable.

No, the data partition will be converted back to ext4 everytime you do "format data".
Not formatting your data could keep the f2fs status, but it's risky to not formatting data when changing ROM in lavender due to it's strict encryption issue.

Miui.eu ROMs doesn't fully support F2FS. The rom does, but the kernel doesn't.
You need to make sure both the ROM and kernel has F2FS support.
if one of them don't, you'll get bootloop.

I've been on F2FS since.. April I think, and I've installed and tried so many roms without any problem.
here's what I normally do and it works all the time:
- Make sure data & cache are ext4
- format data
- reboot recovery,
- wipe cache, dalvik, system, data, internal,
- flash firmware
- flash ROM
- flash gapps (optional)
- flash magisk
- flash kernel that has f2fs support (optional, if the rom's kernel doesn't support F2FS)
- reboot system
————————————————————————
it's necessary to install the rom in EXT4 because automatic encryption doesn't work in f2fs partition (I think... based on my experience). granted, you can do the encryption manually from settings, but it's require to have 80%++ battery and the more stuff you have in your internal, the longer it'd take to manually encrypt the device. automatic encryption is just easier to do. You can leave your internal decrypted as well, but you won't be able to use your fingerprint or any screen lock methods. That's just how redmi 7 family works.
————————————————————————
- once you get into system, reboot to recovery once again
- convert cache & data to f2fs
- flash magisk
- flash universal f2fs patch
- reboot
now your /data and /cache are in f2fs.
If you're already on a rom and kernel that support f2fs, you can just do the later half of this tutorial without the need to reinstall rom and everything, but you'd lose all your data. good luck!
What's the benefit of changing cache into F2FS?

Thanks
thx for guide.
Which custom rom that support f2fs?
