Doesn't seem to work on openSUSE Tumbleweed #2

Hi,

I am testing this on openSUSE Tumbleweed, and it doesn't seem to work. It properly loads the configuration, but from what it seems, the zram device doesnt have a valid swap header.

doing a mkswap "zram device" and then swapon "zram device" works.

Thanks

Same here - using openSUSE Tumbleweed and cannot make it work:

# cat /etc/os-release

# zramcfg -c /etc/zram.cfg save

mem_limit file is not set to be readable. Is there an example of the .cfg file somewhere? I'd create manually as a workaround.
