Add external USB Storage for Logs, MariaBD and InfluxDB

Hi, I’m running Home Assistant as HAOS 10.3 on a Odroid N2 (HA Core 2023.6.3). I have installed the OS on a 32GB eMMC.

To save space I want to move logs and databases to an external USB SSD.

What do I need to do? I’m not a Linux expert. I know that I have to mount the USB drive somehow. And how do I move logs and databases to the USB drive?
