I installed Armbian on SBC Odroid HC2 and then OMV 5 following "Installing OMV5 on Armbian Buster" guide. I transferred the system to the hard disk and everything worked perfectly. I did the tests to understand how to manage the environment and the services configurations.
So I decided to start again the installation from scratch to make the production environment using the same board. Here too it went smoothly, no errors during the installation.
However, at the end of the installation script, when I reboot to connect to the graphical interface the browser http://ip replied "Connection failed".
But before the reboot I checked with the command ip addr the address assigned by the router, and it was the same as in the first time. The server has disappeared from the network and even with ssh root@Ip it is no longer reachable (No route to host). Searching the router for connected devices or with fing command the machine with that MAC address did not change to a new ip address on the network. It is as if the OMV installation script had failed the network configuration.
I repeated the installation several times to find out if I had made any mistakes. I always got the same result. I can no longer use OMV on the same board on which I have already installed it the first time. Can anyone give me some advice on how to manage this problem? Thanks.
