April 9, 20251 yr I've been running Unraid for two years, and decided to get a GPU for transcoding video. After trouble getting Unraid to recognize it, I moved PCI slots and at some point my ethernet cards stopped getting IP addresses. It MAY be possible that I accidentally disconnected power from the server before it was totally shut down. I am at a total loss of how to fix this after reading suggestions. Hoping someone can help. Attached is my diagnostics output. Also removed the video card in an attempt to get things working, which didn't help. tower-diagnostics-20250409-1317.zip Edited April 9, 20251 yr by armed-stork1532

April 9, 20251 yr Author No, it's a Dell r720 with an NIC board with 4 ports (all are connected) and show up on ifconfig as connected at least:
April 10, 20251 yr Author I tried that and the switch its connected to, still no luck. The server has something called iDRAC which allows me to connect to the terminal without a monitor and it's on its own dedicated ethernet port and works just fine which is why I didn't think to even reset any of the hardware
April 10, 20251 yr Author I made a brand new unraid usb stick and booted it, same thing. So is it something hardware related then? Like the NIC got friend somehow?
April 10, 20251 yr Community Expert Any chance you have something bound to VFIO? Adding a new piece of hardware can move the IOMMU groups around causing things that were there before to disapear from the host OS... I lost my drive controller when adding a wifi card once.
April 11, 20251 yr Author I don't think so. I am at a total loss here. I installed a new usb stick with Proxmox just to see if it would get an IP through DHCP, and it did without a problem. I even flashed a new USB stick with Unraid, but still can't get an IP address. Flashing a new stick completely clears the config, right? Any ideas? This is really stumping me.
April 11, 20251 yr Author Well this is the last thing I would've thought was causing problems, but apparently having the case cover open was causing me all these network problems. Definitely no explanation why it would work in Proxmox but not Unraid but all that matters is it works now....
