ZRAM? How to edit disksize?

[Duepointe]

I have a Kata Box 2 with s905 SoC with 1GB of ram

My current ZRAM value is set at 500MB with a swappiness of 60%
I can disable zram or change the swappiness of my ZRAM but I cant seem to change the disk size.

I tried this in the terminal with su

swapoff /dev/block/zram0

echo 1 > /sys/block/zram0/reset

busybox echo 157286400 > /sys/block/zram0/disksize <- I want to lower it from 500mb to 150mb

mkswap /dev/block/zram0

swapon /dev/block/zram0

I checked the value of /sys/block/zram0/disksize and its still set at 500mb or nothing has changed.

I tried to edit the manually but its not saving at all.

Idk if your still after this, but may help others if not

Try taking the size down to 0 before setting the size and wrapping your echos and I don't think you need busybox, seems odd how you used it just for one of your echos...

swapoff /dev/block/zram0

echo '1' > /sys/block/zram0/reset

echo '0' > /sys/block/zram0/disksize 

echo '157286400' > /sys/block/zram0/disksize 

mkswap /dev/block/zram0

swapon /dev/block/zram0

Thanks, i will try this in the future.
I was able to find a way to change it by finding the sh script for creating the zram under /system/bin called lowmem_manage.sh.
i just removed the if-else script in creating the disksize and just made it simpler by just putting
echo 300M > /sys/block/zram0/disksize

Cool glad you got there in the end. That script might of been the reason for why your way didn't work in the first place. I don't have lowmem_manage.sh on any of my devices.

yup.. i found this lowmem_manage.sh on s805 device as well and some other s905 roms or sometimes a filename called zram_mount.sh
