Does it makes sense to format /system to F2FS? Will it give much difference in terms of performance?

    To all experts:

    I'm running stock COS12.1.1. I was just wondering if it is worth the effort to convert /system to F2FS (Data and Cache already converted), since I heard that you won't be able to install OTA's/upgrades anymore on the system partition because it's changed from EXT4 to F2FS, is this true? @Reboot101 @Aaahh @gaster @semper80 @MZO_ @TugaPower @69gm

    There is much confusion what this subject concerns (even on XDA) so I hope that you experts could help the OnePlus community (and me) to clarify this.

    Thanks in advance friends.

    I'm not a developer but from my understanding, F2FS can be faster, but YMMV. Not all ROMs support it so make sure you read the OP carefully for each ROM. Some people swear by it, others shy away from it because it is not as tried and true as EXT4.

    Stick with ext4, for one I don't believe that cos supports it. It will making upgrading a bit of a hassle.

    Try converting /System to F2FS. I'm sure it will give you an error.

    I have converted from ext4 to f2fs and i don't feel any kind of difference though in usage...
    Note:- changing file system leads to complete loss of data like everything on internal storage

    In my opinion the f2fs/ext4 doesn't have much of a difference... I've noticed difference in copy pasting big files only. Speed doesn't decrease on f2fs. If ut is about system then I'd say you should stay on ext4, not gonna make much of a difference

    It doesn't support it via the official way, however, you can manually modify the boot.img and the fstab.grouper to work with F2FS, but as Aaahh said, it will be a bit of a hassle.

    Devs and all who responded, I thank you all for your time and effort,

    Have a nice day friends.

    Yup. It's nice that work is being done to improve filesystems further, but this won't magically make the phone 10% faster. So if your objective is to gain time, it's definitely not "worth the effort" to migrate to any unsupported filesystem in general I'd say: you'll spend more time getting it to work than the time you'll ever save from running it over the life of your device.

    @Abdel-1993 I dont think COS12.1 supports /system as f2fs. That could break many features & could also cause your rom to not boot properly/bootloop. So I would recommend not to take risk.

    Still if you are willing to take the risk, then take a full nandroid backup in twrp > format system as f2fs > now either clean install COS12.1 yog7das2k1 flashable zip (or) first in twrp settings, tick the option use rm-rf instead of formatting (this option prevents twrp from formatting the partition back to ext4 when restoring a backup) & restore only system partition from backup. :)

    in the case of desktop linux, ext4 is more supported.
    other filesystem types are mostly targeted for servers

    You can convert data and cache to f2fs. Leave system at ext4. But as we learned from the comments above there is not much difference between f2fs and ext4.
