Purpose of adding network interface

    • OMV 4.x
    • Ok, so I answered my original questions by YOLOing it. I wanted to backup the OMV SD card onto my laptop, but I ran into the same problem described here unix.stackexchange.com/questio…tecting-sdcard-partitions so I risked my OMV installation to bring you these findings and satisfy my curiosity.
      1. Adding a network interface in the OMV GUI is necessary to get network statistics to show up in Performance Statistics. Interestingly, the statistics are gathered whether they are displayed or not. By adding my interface, the statistics from months ago appeared. When I removed the interface, network statistics went blank again in Performance Statistics.
      2. Removing the interface seems to break OMV... I thought I broke my setup, because network activity and pings no longer worked to my OMV machine. I pulled the power plug and replugged it and fortunately it seemed to have saved the interface, which showed up again. Tthe GUI displayed the yellow notice that for changes to take effect I must either Apply or Revert (I had applied when it broke the network). This time I reverted, and all is good.
      Is there some kind of emergency recovery built into OMV? Not sure how that happened, and I was curious to try removing the interface again, but that's enough experimenting for today. :)
    • Cheeky. :P

      Some motherboards have the ability to restore old/default settings after unsuccessful modifications/overclocks. I wondered if OMV might have a similar functionality. That would be a cool feature!

      Technically, an inaccessible device isn't a failure, but I still don't know why it reverted the network settings after I unplugged/replugged it. Maybe it hadn't finished applying them.
    • I want to come back to the main topic the network interfaces.

      don´t ask me how but on my initial setup I configured the etherenet and wifi modules. So when I plug the ethernet cable to my nanopi it leases an IP for the ethernet port and another one for the wifi. So far so good.

      in case I reboot the nanopi without connection to a ethernet cable network there is no connection anymore on both network interfaces.

      Used the stock armbian nanopi OMV 4 image... Would be really happy if anybody can mentor me with this issue...
