I just found this OMV forum entry:
 
https://forum.openmediavault.org/index.php?thread/30093-configure-cpus-cores/
 
maybe you can convince OMV to use all cores with this (taskset). Since I am no OMV user I did not dig further in this.
 

Hi,
 
I could not reproduce this behavior on my ODROID-XU4 with current Armbian (Armbian 22.02.1 Bullseye) :

I guess your application does not have multiple threads so it does not occupy all cores at once?
 

That nobody knows anything about your situation:
