July 12, 20205 yr My first problem is that I have my USB controllers passed through so I can't use the GUI. I can't access the server at all as a result. I managed to boot it in safe mode so I had access to the GUI with a keyboard and downloaded the diagnostics while the network was not working and it downloaded to a Downloads folder in root... but then when I managed to get the machine to boot with the network working it had dissapeared.

Currently I don't have a spare USB controller, and for 12 months I've had no problems booting from a USB3 port. It is the folder /root/Downloads which is where it put the diagnostics when I downloaded them.

Unfortunately, that location is on the RAM disk that Unraid uses when it installed Linux. The contents of that directory are lost when the server is rebooted. You would have to copy the Diagnostics file from that location to a permanent storage media. I would suggest using the flash drive which is located at /boot and then use the command poweroff to shutdown the server.

I'll be back tomorrow when I have time to recreate the issue.
July 13, 20205 yr Author Okay, got it to repeat the issue and grabbed the diagnostics this time: tower-diagnostics-20200713-1129.zip
July 13, 20205 yr Community Expert I am no expert on Networking but it appears that the bonding of your two NIC is failing to happen. I am going to ping @bonienl and see if he will add his insight as to the possible cause. Edited July 13, 20205 yr by Frank1940
July 13, 20205 yr Author Thanks, would a possible solution be to diable the nic I don't use in the motherboard settings? ( If that's possible, I haven't check yet )

( If that's possible, I haven't check yet ) Absolutely. However, I believe you should probably rename the network-rules.cfg and the network.cfg before rebooting to force their recreatation when restarting the system. I know that a lot of folks do disable the onboard NIC when they move onto Intel based NIC cards.
July 13, 20205 yr Author Unfortunately my mobo doesn't off that option. ( just looked ) It get weirder.... When it boots without the networking working I can get the networking working by swapping the ethernet port I'm using..... but then when I reboot I have to change back to old one... and so on... seems like with every failed reboot swapping the network port fixes it. So this defintely seems to be an unraid issue.
July 13, 20205 yr Community Expert As I remember, this is a problem that can happen. It depends on which NIC is 'discovered' first as to which is assigned as eth0. I also seem to recall that you can also 'force' which NIC becomes eth0 by permanently assigning its MAC address. You would have to look at the Settings >>> Network Settings to see about doing that... You could also just plug a CAT5 cable from your switch in to the other RJ45 connector for the second NIC. I seem to recall that some folks did this but I suspect it could also have some ramification with MAC addresses and IP addresses issues in the larger networking picture.

It is usually buried in the place where you turn off the sound module, video GPU, serial port, etc. This may be a couple of layers down in the BIOS menu system as most people never have to use it...
July 13, 20205 yr The problem is both your ethernet ports use the same MAC address, which is not allowed and gives conflicts and explains your 50/50 situation. This is a known issue with some ASRock motherboards. Do you have one? A BIOS update may resolve the issue. Alternatively you need to disable one of the ethernet ports.

Interesting! I looked in ifconfig.txt in the Diagnostics file and saw it. WOW!!! I had always thought a MAC address was permanently 'burned' into the NIC chip. Shows what assuming will eventually get you... Just sitting here thinking about it. What possible advantage could be gained by adopting a MAC address from another device? (I always had the impression that the uniqueness of MAC addresses was the one staple item in the whole networking universal.)
July 13, 20205 yr Modern NICs allow you to change the MAC address, "burned" in was a long time ago in the beginning of ethernet. IMO there are no real reasons to clone MAC addresses, it usually gives more headaches than advantages. That said, when replacing a device and the new one needs to be an exact copy, this is a trick often used to prevent changes further down the chain (e.g. firewall).
July 14, 20205 yr Author Unfortunately I have dug through all the BIOS options and there's no way to disable the network interfaces ( It's an AX370 board and it's a very threadbare BIOS due to the amount of CPUs it supports ) I'm also on the latest BIOS that was updated this month.

Also see if they have a Users Forum. Sometimes, you will get quicker response there.
July 16, 20205 yr Author Thought of a solution, I used the vfio boot setting to make one of the ethernet ports available for passthrough. As a result UNRAID doesn't see it at boot.
