[Q] How to make EXT4 ?

I did partioned my SD CARD (4GB stock with DESIRE) through ROM manager , where the only available option was 512MB EXT3.
IM using Windows XP & I'd like to make EXT4 partition (Need alignment EXT4 for
InsertCOIN ROM )
So is there any way ?

use gparted from ubuntu (download + burn an image of ubuntu and boot using the cd) or use fdisk.
maybe here u can find some useful info

with gparted no problem at 3years old kid
Just download http://gparted.sourceforge.net/livecd.php burn using nero ar other burner boot cd and make as you need. You must change in bios boot priorities to start use cd. NO install need, after booting a cd you get temporary linux from cd. When you turn off cd from your pc - xp returns back.

I advice you to get magic partition manager (perfect for windows plateforms)
and format all the sdcard :
a fat32 partition
a ext2/3/4 partition of maximum 1Gb (best performances)
Enjoy it _ hope it helps you

[Q] need help choosing hboot

Im currently running the RSK rom 7.2 with stock hboot and im wondering is there any point to changing to cmr2? I mean apart from changes to the memory layout what sort or performance changes will i see?

The more internal memory = more space for dalvik on internal storage = overall better performance.

regarding flashing kernels etc is radios the only thing that cant be flashed from recovery when changing to cmr2?
Also would i be able to use titanium to restore apps+data even though the app backups were made using stock?

You can't flash radios with .zip method in cm7-r2 due to low cache partition. You can do it with other method from PC.
Yes, I think that you can restore, but the app will see different available space.

Depends what ROM though, sometimes if the ROM throws too much stuff in the sd-ext partition you can get quite bad performance in comparison to using the Data hboot. Just sayin'.

Cache partition size matters for ICS roms?
I'm on Data++ and I have about 100 MB free space for apps on /data (without sd-ext).
Would switching to Bravo Sense table (with 35 MB plus cache partition size) improve the performance on ICS based roms (like BCM or Sandvold's) or these roms do not use that partition anyway?

I've found that a 2Gb ext partition works well for me (using RSK rom). I'm using the Data++ Hboot.

I use cm7 r2 running Sandvolds ICS with dalvik & apps to ext4, runs very smooth and fast. Class 4 16GB SD, 1GB ext4.

EvoHd2 V10 Final FIXED by Mr evil with native cronmod INT2EXT

I can take no credit for any of this,This is my first ever post of a ROM I have altered to suit my preferences ,This is a great ROM but I hate app2sd and prefer this method I use myself so I have decided to share it in the hope some of you may find this useful, I prefer NAND and as such storage space is always a issue so I modded this Rom slightly to suit my preferences, All I have done is mod the init.d as when installing standard and then flashing cronmod INT2EXT the phone gets stuck on boot screen and has boot loop due to mount conflicts between cronmod and other scripts in the init.d folder, also it becomes very very slow so I have ripped out the conflicting scripts and repacked the Rom, full credits and BIG THANKS to Mrevil.. Credits for groundwork: SecureCRT, wis1152, tytung, ankuch, rapmv78, boonbing, the CM and Evervolv team and Massive Thanks to XDA Senior Member croniccorey for the cronmod INT2EXT script and XDA for such a great community and excellent site.

LINK TO THE CRONMOD THREAD HERE:http://forum.xda-developers.com/showthread.php?t=1716124
PLEASE NOTE: THIS HAS ONLY BEEN TESTED ON 250MB NAND BASED INSTALLATION AND IS UNTESTED FOR ANY OTHER METHOD !.
YOU MUST REALLY HAVE A MINIMUM CLASS 8 SDCARD PARTITIONED TO EXT2/3/4 FILESYSTEM BUT BETTER WOULD BE CLASS 10 OR IT WILL BE AS SLOW AS A DRUNKEN SLUG TRYING TO MAKE IT TO THE NEXT GARDEN
INSTRUCTIONS: Partition sdcard to desired size, I use clockwork and choose (2048) 2GB EXT WITH NO CACHE. then choose install zip from sdcard, flash ROM , reboot and hey presto enjoy system size of 2GB for apps with nice speed !
Big Thanks once again to everyone involved for allowing me to mod this Rom....peace out

Link2SD with [ROM/4.1.2] [Dec 01 2012] CM10 | Jelly Bean 4.1.2 - v2.7

I love link2sd and would like to take it with me after I upgraded my Desire from CM7.2 to a CM10mod.
http://forum.xda-developers.com/showthread.php?t=1945441
But even after erasing the A2SD Scripts, I get a message telling me ext3 is not orking with this rom, giving Fat32 a try is recommended.

You think it's worth the try to format the 2nd partition in FAT32? Or do you have another clue what could be the matter?

It says that sd-ext2 isn't working, because you probably don't have a second ext partition, and you won't need it.
Try going through settings and stop the app from searching for a second ext partition.

Hey - thx for your reply!
I was running link2SD ith CM7.2 before. So my SD should be still parted into a main partition for all my mess and a 2nd ext3 partition for link2SD to store the apps.
That's why I wonder why link2sd it is not finding it...

So, you have a fat32 main partition with all your stuff, and an ext partition for apps. Link2sd is looking for a second ext partition, as if you had 3 partitions on your sd-card. As yoy don't have a third partition, it gives that error.

Ummm - a second as if there were 3? That's confusing me. Why can't it find the ext as before?
And how could I point it towards that one?

anyone left who'sgot an idea?
Is the ext3 not found?
Is an ext3 not working with this ROM?
thx!

Ext3 work in this rom, in the developer thread an user use it.
First ics based rom i installed give me some trouble due to wrong partition alignment, previous working on gb. Can you check partition in your recovery?

Convert to F2FS

Is there a guide to convert Z2 to F2FS? Are there really improvement doing this?

Twrp>wipe>data/cache > repair partition> change fs>f2fs
Is kinda a ntfs,exfat,fat32
Yes, there is an improvement , such a gret R/W speed

Do you recommend cache as well? Some guy said that the cache partition needed space (does f2fs uses more space?), and suggested repartitioning only data.
Thanks! Excited to try this... When I backup all my data
EDIT. Alright I'm using F2FS on cache and data, so far so good!

Tempted to do this as well, could somebody do back to back Androbench?

Alright!
Just did two tests, stock settings (no OC) using AICP ROM.
First run

}
Second run clearing memory and turning off wifi.
Third run using 2.3 and 1.7Ghz.
Got much better SQL scores with OC
EDIT. Would be nice if someone with ext4 posted results for comparison. On the other hand, we are seeing the limitations of the type of memory in the Zuk Z2, which is eMMC.

Thanks for testing, here are my results below for comparison
Setup is - Encryption On, EXT4 on all /data /cache /system, Marshmallow ROM (Resurrection Remix), No OC or anything, standard CFQ scheduler
Hmm, I'm wondering what effect encryption has on the speeds. Also, I think you're right, the newer phones that I've been looking at with UFS 2.0 nearly all hit 450MB/s and the UFS 2.1 phones are up around the 700-800MB/s mark. However, for the price and comparing to other eMMC high-end devices, I'm pretty satisfied that Lenovo didn't cheap out on the storage.
Text version:
Seq read - 219.94MB/s
Seq Write - 43.04MB/s
Rand Read - 18.03MB/s, 4618 IOPS
Rand Write - 5.68MB/s, 1455 IOPS
SQL Insert - 185 QPS
SQL Update - 262 QPS
SQL Delete - 324 QPS
Link to screenshot (too big to embed): https://imgur.com/j0nwAgx
EDIT: For reference, here is a professional reviewer's Androbench, running factory ZUI Marshmallow:
Source - https://www.notebookcheck.net/Lenovo-ZUK-Z2-Smartphone-Review.170061.0.html
Seq Read - 239.4MB/s
Seq Write - 46.5MB/s
Rand Read - 21.2MB/s
Rand Write - 5.6MB/s

Interesting... So it would appear there is no significant performance boost from using f2fs. Perhaps in real world usage, but I don't have something to compare to. I mean it's really fast opening stuff but it was already fast before, when using ext4.
By the way using f2fs on cache and data only.

Yes, quite interesting
I will do another test when I convert to F2FS at the next major update and then post results
