[Q] Ext4 Problem

Hey Guys,
I have Team 8 GB Class 10 MicroSD. I did partition and give ext4 to 2 gb.
I installed CyanogenMod and installed Link2SD. I select ext4 partition in first screen of link2sd. But i can't see ext4. My phone gives me no empty space error.
What should i have to do?

What do you mean exactly by "can't see"?
If you can't see it in the file explorer though if that what you mean.
Link2sd mounts the 2nd SD partition on /data/sdext2 I think and won't be needed to be accessed by a user because link2sd will manage the apps and caching automatically.
I hope this helped you

You can't see it but it's mounted. Link2SD deals with everything bro.

Download disk usage and you will be able to see the second partition

This guy did this and he have 834 mb free space. But i have 40 mb free space.
But i already did partitioning.

Your friend is using data2SD and you are using Link2SD. Data2SD merges together your internal storage and your ext4 partition and makes your phone see those like one and that's all, no control after that. When you using Link2SD it won't show total empty space there where you want it but partition is there, link2sd will take care of everything (if you did setup ok) and you have total control over your apps so link2sd makes better choice for most of ppl here...
No worries, if you did all like it should be those 40mb of free space shouldn't change in long time even after install tons of apps

He's using Data2SD and you haven't installed that.

You must to use Data2SD, it's better because the app get installed on the partition in the sdcard, recomend flash the jikantaru patch, search fot it

Thanks for the answers guys.
Here is the problem:
"There isn't any space"
"Nearly all apps at SD and this is the situation"

Hmmm seems like your Link2sd options are wrong... Open link2sd, go to settings and be shure that auto link and relink lib files at boot are checked. Under Auto link settings all three options should be checked. Under Install location, automatic or external should do the job.
Now you should go back to app list, hit Multi-select option and choose all app's that you wanna (or better, you can) move to external space... When you selected apps hit Actions button and choose Create link... That should do the job

You already deleted most of the data on your phone to begin with. That will at least get it functioning again.

considering userdata.img rebuilds the file structure, yes it should.

I have just one more question. When you say:

Becuse i have downloaded the whole ROM, but i cant find userdata.img.
Can you please give me a link or is the userdata.img already there?

Somehow, internal storage came back to me (without the files, but they are not important). So, my problem is (hopefully) solved. I would like to thank everyone who helped me. I cant say how much i appreciate your help. And once again i apologise for stupid questions.

Considering that /mnt/shell/emulated is a fuse mount of /data/media (and later symlink'd to /storage/emulated), it should have been re-created upon reboot. Of course deleting it would have probably deleted all of the data within /data/media, meaning you should have lost all of your "SDCard" data. So long as the original /data/media structure still existed, the rest will always be recreated on boot within init.tuna.rc.

Ur data is almost full. To download an app on google apps you must have atleast 200mb free on your storage. Alternatively u can use link2sd to link apps that u installed to second partition to free up some space

I got it working but I had to change the script on a galaxy note 2 LTE gt-n7105 with cyanogenmod 10.2
it wasn't working, and I noticed that the file /dev/block/vold/179:33 wasn't on my phone but I have 179:16 and 179:17
so my script is now like this:
#!system/bin/sh
sleep 3
mount -o remount,rw /
# mount -t vfat -o umask=0000,utf8 /dev/block/vold/179:33 /mnt/shell/emulated
mount -t vfat -o umask=0000,utf8 /dev/block/vold/179:17 /mnt/shell/emulated
mount -o bind /data/media/0 /storage/sdcard1
chown system /data/media/0
chgrp sdcard_rw /data/media/0
chmod 0075 /data/media/0
mount -o remount, ro /

is thr any way to even access internal 2gb memory..i asked bcoz my sdcard is only 8 gb i want to use internal memory after swapping

will it work on lollipop??

OnePlus 7T System partition size

Hi my friend is having various issues with his 7T I am able to help him, but as the title suggests, what is the system partition size? For him when he factory reset the system is showing its taking 30gb from his 128gb. As I have the 7 Pro and not the 7T I don't know if this is normal?
Any help is appreciated, just to answer the above .........:good:

27gigs for me so we can say it is normal. But i don't think they should need that much tbh :/

Mine is 27GB as well, seems very high indeed.

Now it's 28GB
Excuse me wtf

because oneplus 7t has a recovery partition so you can avoid problems

exactly !
System OTA zip is 2.5 GB. So are there over 10 Copies of old Systems ?!
(And LOS Androids are around 400-800 MB).
So it's just crazy.
Not that I'm running out of storage soon, but that's just about the principle.
I wont accept that some Android OS reserves 28GB for itself.
I can have dual boot Windows and Linux on my computer on that storage space ...
I found another first thread, where I posted/ranted about that, too

But ranting and joking aside, this 28GB System partition provides really ZERO additional value compared to my previous 10GB System partition on the OP6.
So I hope there will be a way to shrink that to some sensible size ...

Looking at my storage, the system partition is 26GB but the actual used space is a small amount of that ~8GB or so. It's mostly empty. Odd.

My guess is it is so big to allow the update to be unzipped and flashed even if you have the phone full otherwise. Remember iPhones used to not update due to not enough space to unzip the update file.

If this is the reason I'd be amazed - they'd be fixing a problem that isn't widespread.

The Op7t has no real system partition. It's so "big" in theory because it's thats maximum space that can be allocated within the super lun0 partition (super partition contains system, vendor, odm and product partitions).
See details over here : https://source.android.com/devices/tech/ota/dynamic_partitions/implement

That makes sense. However is this super partition fixed size or itself is dynamic? If it is fixed then oneplus is definitely over-allocated it, thus wasting space.

SDcard as internal storage in Redmi note 8 AOSP

How to use sdcard as internal storage on my redmi note 8, currently i'm using PixelOS rom. when I go to the setup settings for the sdcard there are two options, using the sdcard as portable storage and as extra phone storage. but when I choose as extra phone storage the formatting process stops at 40% and an error appears "attempt to invoke virtual method 'int java.util.arraylist.size()' on a null object reference". is there a way to solve this error or use sdcard as internal in this aosp?

If you have Magisk, you could try this module: https://forum.xda-developers.com/t/4078731/ (look for its latest version on page #7).
It helped me solve a similar problem on another device -- a tablet, not a RN8.

that module is for enabling rw permission on SCcard ,it's not what you look for ...
this problem may be a PE thing, another member also reported same error

or report to rom dev

Looks like it's a problem from PixelOS rom, I tried to use another rom and format sdcard it works fine.
Thank you everyone for helping me

Partition your SD Card for installing apps and storing other files at same time.
Make sure you have a root shell. If not, root your device with Magisk first.
Start a terminal, and run su to switch to root shell ($-->#) .
Partition your sdcard. Follow the instructions below.
1. Check your sdcard number.
Code:
sm list-disks adoptable
You will get the output like this:
Remember the disk number for further use.
2. Run the partition command to seperate your sd card space. Some space are used to store apps and their data. And the rest space keeps as external sdcard space.
Use this command to seperate your sd card:
Code:
sm partition "disk_number" mixed "reserved_percent"
Replace "disk_number" with your real disk number. Also you can control how much space goes for storing apps and their data and how much you want to reserved. For example you want 70% of SD Card for storing apps and 30% for original external storage, then "reserved_percent" is 30.
Code:
Example 2: Want 60% of sdcard goes to store apps, 40% as external storage.
sm partition "disk number" mixed 40
Press ENTER to execute your command. All data on your sdcard will be destroyed. Back up all data on sdcard first if needed.
Right now the sdcard has the ability to store apps. Move your apps to sdcard as you like.
Voila!
EDIT: I made a detailed guide here. Check it for more details. Press "like" button if helped you.
