[SOLVED] Network issues - Unraid (6.8.3) shutting down Ethernet port

[asnt]

Hi All,

 

I'm having a hard time understanding what is happening with one of my Ethernet ports. My motherboard is an Asrock Xs X99 and has dual gigabit LAN ports.

I had been using the my motherboard LAN port  2 (eth117 - in the picture) since I upgraded the hardware in my Unraid server, but after the last shutdown when I changed my video card from PCI slot 2 to PCI slot 1, every time the server comes up again it shuts the port down.

 

The port is enable in the BIOS and the lights (green and yellow) come up when I plug the cable in, but it shuts down, with no lights, during Unraid boot. I know the port is not bad, because I tested booting a Ubuntu distro through an USB stick and all network features were working fine.

 

Has anyone had a similar problem? Is there a way that I can test the port or try to bring it up within Unraid? thanks!

Please post the diagnostics: Tools -> Diagnostics

Not idea why this is happening:

 

May  2 16:04:52 M93p kernel: e1000e 0000:00:19.0 eth117: renamed from eth1

 

Try deleting network.rules.cfg (flash/config), then reboot, also make sure there's an IP address configured, static or dhcp.

Now it's not renaming eth1 to eth117 anymore, but it is still down:

 

 

Attached is the diagnostics from the last boot.

The probem is both your ethernet ports have the same MAC address, causing a conflict.

 

This is a known problem with certain ASRock motherboards. Check their website to see if they have issued a newer BIOS to rectify the problem.

Thanks! I'll try that and report back.

 

I was planning to update the BIOS anyway because the version that I'm using is pretty old.

Here is an update:

Asrock has a tool to update the MAC Address on their motherboards when something like this happens. I'm not sure what is the rules around external links here, but a quick google search for "Asrock Mac Tool" will take you there.

 

I did this procedure and updated the BIOS. Unraid is now recognizing both ethernet ports with different MAC addresses, and I did test bonding the two ports and it worked. When there is just one ethernet cable connected, even if I set bonding to "no", Unraid stills shuts down the second port. All is working, so for now I will consider this done.

 

Thanks for all the help!

I'm also having issues with my Ethernet port since upgrading. Prior to this issue my Unraid Server was up for months, now it keeps going offline every so often and is unreachable requiring a hard reset (Its a headless system). Nothing else has changed other than the update.
