Hi @igorpec,
Thanks for the hint. I was already lurking the web about it; I've noticed that OMV 3.0 image I was using was actually based on armbian, so I've started from scratch with a clean armbian for banana pi (not banana pro like the original image) installation, and succeded!
As a reference, here is my setup steps to have OMV 3.0 on Banana Pi M1:
- download armbian Mainline for Banana Pi from here (Mainline version has the updated kernel with working acpi (power off) management)
- setup system, update/upgrade
- tweak gpio/leds via device tree: all needed info from this thread (for pcduino3, but it's easy to edit commands for banana pi; also explain edit for uart control, but it is easy to work on leds/gpios) and device tree reference
- follow this guide to install OMV 3.0
