[question] why is the script disabling zram?

[Fuckingnameless]

I assume you asked this on the forum too. https://forum.openmediavault.org/index.php?thread/7633-howto-instal-zfs-plugin-use-zfs-on-omv/&postID=405772#post405772

you assume correctly

looking at the script again i noticed armbian uses ramlog and zram together by default
so I'm confused why do we have to disable zram if folder2ram aka flasmemory does the same as ramlo

[ryecoaaron]

You are free to use ramlog. Just disable installing the flashmemory plugin when installing OMV - https://github.com/OpenMediaVault-Plugin-Developers/installScript/blob/master/install#L130

Other reasons:
When the flashmemory plugin was first written, we weren't even using armbian.
Not all systems are Armbian.
I don't know much about ramlog but flashmemory is moving more than just /var/log to tmpfs - https://github.com/OpenMediaVault-Plugin-Developers/openmediavault-flashmemory/blob/master/srv/salt/omv/deploy/flashmemory/default.sls#L48

I run flashmemory on all of my OMV systems even with nvme. It let me run OMV on an SD card for 5 years. When something works well, we have a tendency to not look for replacements.

you said zram/flashmemory combo would use even more ram? how does that work?

[ryecoaaron]

flashmemory moves files to tmpfs. zram moves files to tmpfs. Some/many of those files are moved to tmpfs by both zram and flashmemory. This will use more ram than just one of them.

is it zram per se or the implementation alongside log2ram on many distros? could that solve the issue?

disable logging to ram by setting `ENABLED=false´
in  `/etc/default/armbian-ramlog
```´

I worded that wrong. I meant log2ram not zram. zram is just compressing. zram could be used in folder2ram I guess. So, your issue with folder2ram wrong is repeating my mistake. If you want to ask for something from folder2ram, it would be to use zram.
