F2FS - Google Pixel XL Guides, News, & Discussion

https://en.m.wikipedia.org/wiki/F2FS
I know most people don't believe in the filesystem. However I am not one of those. I've used F2FS on previous devices and it seemed to make a difference to me. I believe it to be a faster and more efficient filesystem. Most importantly I believe flash storage will last much longer due to the difference in the way the blocks are written.
I don't consider myself a genius so... Im sure someone else knows better than me.
Just wondering if anyone was interested in porting it over our way. IRRC the hard part is building twrp to work with it.

I haven't seen any talk about it on the Pixel XL subforums, no.
Would definitely like to see it happen though.

I think TWRP has to be modded to support it

Correct me if I'm wrong but I believe it would have to be supported in the kernel and TWRP at the same time due to both being in the same partition.

Supported in rom kernel and recovery. I've Used it on the nexus 6 and my galaxy nexus

I used it on the Nexus 5 and 5X and loved it. Would be nice if it comes to our phone.

Why would anyone give this thread one star?
Sheesh, I gave ya five stars to try and balance it out.

You can't mate. Cause it doesn't support hardware based FBE.

Oh, and btw. If any of you do end up getting f2fs, adding "nobarrier" to the joint options speeds it up crazily. The increase from that is much more than just using f2fs.

It's currently impossible. F2FS doesn't support hardware file-based encryption yet.

Maybe someone can get something going when the Oreo hype cools down.

What none of you read was Google's response to that guy. First of all the mount options can cause your storage to become corrupted in the event of a power failure. Also they tested f2fs internally and in real world usage it didn't make a difference in the performance of the device.

It has been stated that most don't believe in the filesystem in the op. This equates no into almost no devs trying to implement it into ROMs/kernels+recoveries. It can be done and file structures stay intact. I've used it daily without any issues on my nexus 6(freewilly). Look at those or nexus 7 forums if you need proof. Everyone knows Google will never implement the fs.

Kernel authors have added support for f2fs, NTFS and probably other file systems for ages. Then you need a TWRP build that can format to that fs.
I wouldn't take Google statement as cold hard fact. If they did everything "right" then there wouldn't be a mod community. They're is plenty of objective data showing f2fs outperforming ext4 in crucial areas like database operations.
Having said that, f2fs is not heavily utilized, a few Moto phones use it and it is pretty new fs. Samsung developed it and they don't use it. Ext4 has been around for.. 30 years? It's a nobraIner decision on their part to take the tried-and-true method rather than risk producing a million devices using a different file system that isn't nearly as developed or seasoned as ext4 is.

F2FS was definitely faster in its early days, but it had issues. As those issues were addressed, F2FS itself got slower. It no longer has a speed advantage. I'm sorry to tell you, but at this point F2FS is snake oil.

I can't be bothered to find something I have no interest in, just to prove someone else's point for them. Lol
Having said that, I don't see any reason my F2FS shouldn't had been added to a recovery build yet if there's interest. If there are more than a handful of people interested, I can create a twrp build with F2FS support. It will take some time since I haven't synced omni repos and made my own recovery image in over six months.

Data2Ext Hack Blows Benchmarks Out of the Water

http://www.androidpolice.com/2010/12/11/data2ext-hack-blows-benchmarks-out-of-the-water/
Pretty big news out of the XDA-Forums today – forum member and resident genius Ownhere has come up with a ‘data2ext’ hack that allows users to enhance the way Android handles OS-specific data and memory. Put simply, this hack allows users to change some partition settings in order to greatly increase performance.
Originally created for the HTC Desire, the hack delivers some outstanding performance improvements and is a must have if you own the device. For more technical information, you can click here. A word of warning, though: this hack is not for the feint of heart as it is fairly difficult.
Interesting..
Pretty nice...3000 points in Quadrant is huge. Maybe we can get something similar to our devices as well...Santa Claus is approaching
not today's but they are great...if the hack doesn't destabilize the device or harm safety...

I read the post howto for desire and it looked sooooooooooo complicated...
This will be fairly easy to implement... but things could go very bad using this mod. Like for instance if you make a sudden power-off... filesystem may stay in such state that it cannot be mounted on the next boot and for novice users this could mean that wipe should be made to resolve this situation.

This problem should only be there if you really disable journaling. From the original post:
As you see, the best speed is: mount real ext4 device with loop option, disable journaling. The best balance of performance and safe is mount real ext4 device with loop option, enable journaling! We don't need a loopfile but just change mount option.
Click to expand...
Click to collapse
As long as journaling is enabled this should be quite safe. At least thats what journaling is for
If someone will implement this, it would require microSD card class >= 4, to use this hack. Am I right?

RFS please

Based on my own experience, as well as many requests in various ROM release threads, as well as many other comments in various ROM release threads...
RFS please.
Any speed gain from EXT4 with no journaling is made moot the first time one has to wipe and re-flash, even with backups (maybe especially with backups, which seem to cause some issues as well).
I like speed, I overclock my computer, my video card, and even my phone, but I need stability in my phone. I need the dependability that if my phone crashes it isn't going to force me to do a wipe and re-flash half the time. So... suppress your inner flash-happy geek enough to realize that stability and dependability are important aspects of a phone and at least give the option of an RFS file system.
You are in the minority my friend,90% or more that use EXT4 have no problems at all,,,I don't trust no journaling 100%,but I havnt had 1 problem running it for almost 3 months; And you can enable journaling...

Same here... I haven't had a single problem on any of the ROMs I have run here. I have been enjoying speed + reliability.
I understand what JMMusic is saying though...the whole premise of having a custom ROM is that you can modify it how you want. Maybe RFS should be an option for those that want it. I do think that EXT4 with journaling enabled is the best route though.
I personally agree with OP. I'd rather have stability over speed in my phone. I? Ok with just ext4 journalling over rfs, but I would rather have journalling on.

I cosigned OP, this is the reason I'm not flashing anymore custom roms now. Everybody is on this ext4 banwagon. I'm good, they can miss me with that. I've never had problems out of the ordinary from RFS. I can go on for days about ext4. When I do flash a rom it will be CM7 before anything now.
I hate "Top Flight Security Mods"
Add me to the jouraling ON list. I need stability more than I need the highest quadrant score.. Re-flashing gets old when your supposedly great ROM decides to bork itself every couple days.

Lucky you. I flashed a certain popular ROM. Everything was amazing...for a few days. Then it screwed up. Flashed it again. Everything cool. Couple days later it's crashing again. This process happened over and over. I NEVER had this problem with stock or stock minus bloat or stock minus bloat plus OC kernel. Only when using an EXT4 ROM with journaling turned off.
Coincidence? Not.

Stock ran very well for me. The only reason I went with a custom rom is just because I could. If I do start having issues such as data corruption, then I probably would go back to stock. So far though I guess I am lucky...I just hope I stay lucky for another 15 months or so when I'm eligible for my next upgrade.

That's why I gave it a go too. I didn't fare so well. Performance was amazing, but it never lasted. You could almost set your clock to the system failure. I'm not the only one, either.
No RFS for me but EXT4 with journaling enabled would be nice.

I have to respectfully disagree here - apples and oranges. Huge differences between an OS and FS here. Yes RFS is older and slower but does seem to be less prone to corruption. Luckily I have 2 phones, the epic being for personal use so I don't mind the risk. But if this was my business use phone Id want the functionality of custom roms, and the slow but sturdy filesystem. Just my .02....

I don't know if I'd go that far. RFS is compatible with FAT so it can be read in windows. Not having to connect a USB cable to copy files from/to your SDCard is an advantage over EXT4.
Of course, while writing this post, I got curious, searched and found ext2fsd. Which might provide a solution to the ext4 'disadvantage'. Haven't tried it though.

I don't understand. How could you transfer files on RFS without a USB cable? I did then, and now, with an FTP server. Was there another way?
I need stability over performance. That is why I've stayed with stock. I would be using SRF 1.0.1 right now if it had journaling enabled. Then again, I haven't had the time to do the research yet on how to enable it after the fact.
Sure it's nice to frequently backup to have a snapshot handy, but that should never be a requirement to maintain stability of a custom rom, IMO.
The lack of journaling still doesn't detract from the good job the ACS crew has done thus far with CIQ removal and whatnot.

AnandTech is of the opinion that the AndroBench tools are not yet functioning properly on Lollipop. It was the AndroBench toolset that Ars used to cook up their NAND comparison.
Once developers get their hands on it, they will figure out how to disable encryption. They could possibly use a hard flash method which replaces entire sectors of the NAND with new data. Simply flashing a ROM/kernel probably won't be enough.

Benchmarks don't matter. Are found in normal use the phone is slower than a N5, which is what a normal user will experience. That's what's so bad.
Also, encryption has nothing to do with this. You can enable encryption on Windows and it barely slows down disk access, if you have a modern cpu. The Nexus 6 chipset is plenty fast, so the slowdown is due to flash memory not being fast enough.

805 is v7 and does not.
In which case encrypting everything by default is a bad decision. No one wants a phone slower than a N5. Did Ars get a bad unit? They are highly respected.

Its just a software flag that tells the firstboot process to encrypt the phone. It is described here: https://source.android.com/devices/tech/encryption/
*** quite trivial to disable.
More: Its just a parameter in the fstab, which is a plain text file that describes to vold, what to mount where. Changing the flag from forceencrypt to encryptable fixes it. Note that this file is in the root fs, which means that the boot image needs to be unpacked and repacked to modify it.

AOSP Rom

Was able to get a ROM built and running based on LRX21V straight from source. Just trying to get a feel on how many people would want to run AOSP. There are some bugs present such as video recording causing the camera to stop working. I think there are binaries missing that Google didn't include in the binaries that are available. Same problem happened on the Nexus 5. Didn't test it much as I just purely wanted to see if it booted.
Also there is a lack of gapps available so I won't be rushing to get anything out. Let me know what y'all think and I'll try to tackle this to get some other options out for us.
Here is the test build for those that want to have a look. This is just a test build so bugs are to be expected. Video recording does not work. Haven't tested it completely as I need a fully working device this weekend. This is for those that have free time to just nit pick and find all bugs in this. Please report back after you are done and let me know what else you may have found that is broken or not working right.
Stock Google kernel (so if you flashed the kernel image to remove encryption your phone WILL be encrypted again)
Built off 5.0.0_r7 from AOSP
Flash ROM, flash gapps and flash SU that is linked below. This will allow root access on the stock kernel.
You can also optionally flash the custom boot image after flashing the ROM, gapps and SU by rebooting to bootloader and fastboot flash boot the custom encryption kernel. That is optional. Be sure to go back in to recovery after flashing the kernel to reflash the SU to make sure it was not overwritten.

No. Minor bug fixes for the particular device it was made for but that's it. I did notice on the N5 that there was a significant "miscellaneous" battery drain on r7. Might roll back to r3 if its present since r3 is the one for us (its also the same build for the N5).

As I wanted to attempt to pre-root and make some changes... Ugh.
Simply installing the SuperSU apk is enough for root, correct? I don't have to re-run CF... Especially since I'm not near a PC

Yes just use the one I linked to. Be sure to flash it in the same session so you don't lose the custom recovery.

Remember its just a test so I recommend waiting until you have access to a PC. Just in case lol
Well, I bit the bullet. Only lost a few downloads.... But anyway.
Sound quality seems.... Different? Also network says its connected to LTE, but its beyond slow. Not sure why exactly.
I'm on the correct APN.
Closing apps, I hear a slight buzz/tap three tomes when hitting the home button.

Did anyone's storage decreased afterwards? My nexus says that there is only 23gb of storage despite being a 64 gb

I have a 32gb and that's what I have.... I didn't check before.... Anyone have any idea what storage should be out of the box?

I was getting weird audio sounds at first... I don't know if it was the update when I got home that fixed it but it's been non existent since the first couple of hours I had the phone

External SDcard performance (US996)

I'm in the process of building a new phone configuration using a V20 (US996) running LineageOS. (14.1 at present, current nightly build)
I have a high-performance Samsung SDcard in it (128GB Evo Select) which is capable of about ~60MB/s write and 100MB/s or more read speed.
In my LG G4 (also running LOS but a late November 2017 build), using a 64GB version of the same card, I get around 45MB/s write speed based on a couple of benchmarking tools I have.
But the V20 only seems to achieve 15-18MB/s write speed.
Is this some kind of terrible hardware flaw with the V20, or ???

You should probably ask this in the lineage thread

Your comment makes little sense.
The OS in both examples I mentioned is mostly the same, the main difference is the phone hardware.
I am simply trying to ascertain whether this sort of performance is common for that device when using a high-speed card.

No, it makes sense.
Lineage for V20 is not the same as for G4, or most other devices for that matter.
This might be some problem with the LOS lg msm8996 kernel, which of course LOS for the G4 does not use.
All I'm trying to ascertain is what kind of speed people are seeing with their V20's in general.
If' it's significantly better than what I'm seeing, I'll check the OS-specific forums. Thanks.

Get way faster than that but I'm on stock ROM so that doesn't help sorry. I'll try to find my other thread I had in here that has my results
I've never used lineage on v20 but that would be prime suspect considering all the roadblocks getting it to even run right that I've read about lol

That's the thread if you are interested there area free other benchmarks from other people.
Trying to attach the pictures of the card and results but it keeps saying network error on xda labs. I'll try later but I think they were on page 8
Using A1 SD Bench on Super V20 with MK2000 and a 200GB Sandisk A1 microSD I get
Read: 78.8mb/s
Write: 27.20mb/s

Actually that helps quite a bit, since it corroborates my initial conclusion that this is not a hardware issue, it's a software issue.

Oh? Do tell. I haven't had the V20 for long yet but I did already get a response elsewhere that there were some unique things about it besides the "2nd screen" thingy and DACs.

Great resource, would probably have taken me a long time to find that on my own. Thanks much, I'll look at it a bit later.

Thanks much.
The write speed there is still a bit disappointing though, given that that card should be able to do, according to some reports, at least 2x if not 3x higher than that.

Not really, in THIS test, you can see the SDSQUAR does 33.4mb/s write and 92.8mb/s read. I'm in the range.
