This is a bit of a long one and I don't know what is happening so I'll explain everything as best I can.

 

Server

CPU: Ryzen 3900X

RAM: 64GB 3200MHz

GPU: P2000 & 2060 SUPER

Drives: 1x Parity, 14x Array Drives 1x NVME Cache 1x SSD Unassigned Device

 

How it all started is i went to use Plex and saw the server not reachable. I have a monitor and keyboard/mouse attached to my server and it was unresponsive so I shut it down. Upon trying to restart it, it would not boot post. I tried many combinations of RAM and various GPUS unplugged and NVME drive removed until I removed the unassigned SSD and the system booted. But alas we have a different issue now.

 

Regardless if I booted into CLI or GUI mode, as soon as it prompted for a username it froze. I was unable to type anything. If i hit the power button, it triggered the shutdown sequence and it shut down. For some reason, removing the 2060S allowed to system to boot and log in via CLI and GUI. However, this is where we run into my current issue.

 

I cannot access the server using the IP address assigned to it about 3 years ago. Never had this issue in all this time. Using the GUI on the machine itself, it reports a different MAC address to the one used in the IP Address Reservation on my router (nothing has changed hardware wise in the past 2 years). I updated the MAC address on the router so it matched but it still doesn't. Lots of router restarts, unraid reboots and netowrk.cfg deletes and re setups and nothing seems to work. If i turn off static IP on unraid, it gets the 169.* address which is outside my range (192.168.0.0). I also cannot reach the internet from the server itself, pinging 8.8.8.8 returns a Network is unreachable. 

 

TL;DR: Unraid can't reach network, can't reach unraid over the network. no hardware changes have taken place. DHCP static and automatic not working

Okay so get this. I recently added a second network switch to a different room in my house which had 5 devices connected to it. I decided to investigate that situation because none of those devices were getting network access either (didn't get a chance to test them before, only just installed them yesterday). Turns out I used a spare cable to hook up one of the devices and it was actually shorting in the switch (it was actually the first cable I ever made back in the uni days). So because of that short, it took out the main switch too meaning no one was getting internet. I removed the cable and everything works now. This is 11 hours in.
