Nothing gets created as result, rolling back to kernel 6.14.10-artix1-1 works (as well as using the lts kernel).

Also the Artix package is still on version 0.2.1 while zramen is already on version 0.7.1 👀

Here zRAM works:

Code: [Select]

$ uname -a
Linux linux 6.15.2-artix1-1 #1 SMP PREEMPT_DYNAMIC Wed, 11 Jun 2025 07:37:25 +0000 x86_64 GNU/Linux
$ zramctl 
NAME       ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram0 lz4          31,3G   4K   44B    4K         [SWAP]

But I'm using it with rc.local:

Code: [Select]

$ cat /etc/rc.local 
#!/bin/sh

# zRAM-Swap (für stärkere, aber langsamere Kompression, "lz4" durch "zstd" ersetzen):
modprobe zram && echo lz4 > /sys/block/zram0/comp_algorithm && echo $(($(grep 'MemTotal:' /proc/meminfo|awk '{print $2}')*1/1))K > /sys/block/zram0/disksize && mkswap -qU clear /dev/zram0 && swapon -p100 /dev/zram0

exit 0

Thanks this method works,

I will report this to zramen.

Some years ago I used zramen to learn how it works, to do it my way.

So I can use zRAM for compressing RAM-Disks too:

Update, I reported the issue and zramen fixed it:

https://github.com/atweiden/zramen/commit/e7a66d085b62f6a9ca43632328c8501a6ee568ba

Indeed it was a change in the kernel.

All that's left is updating the Artix package.

zramen is still outdated
