Hello everyone, maybe someone here knows a solution to the problem.
I assembled a small NAS and installed OpenMediaVault.
The computer itself has a 1GBit/s OnBoard LAN connection.
Additionally I installed a 10GBit/s network card (Edimax EN-9320TX-E).
The network card works correctly after installing the driver because it does not have "good" Linux support.
(Tutorial which works https://noobient.com/2018/08/1…-ethernet-card-on-ubuntu/)
Now for the problem:
I have connected both LAN connections to the switch.
I have now noticed that all network traffic goes through the 1GBit/s OnBoard LAN adapter and the 10GBit/s card is not used.
If I physically disconnect the OnBoard LAN card (pull the plug), I can no longer connect to the NAS.
Link on the 10GBit/s card is still there.
I gave both adapters a static IP address.
10Gbit/s XXX.XXX.XXX.XXX.205 /24
1Gbit/s XXX.XXX.XXX.206 /24
When I physically disconnect the 1GBit/s adapter, comment out the adapter at /etc/network/interfaces and reboot the computer, everything goes through the 10Gbit/s card.
The strange thing is that I can't adapt the network adapters via the web interface.
I can't assign a fixed IP address from there or activate Wake on LAN.
I have to enter everything via SSH, because OMV runs into a timeout.
I'm not the biggest Linux beginner now, but the whole thing is a bit weird.
