No Longer Booting After Moving PCI Devices

[ccigas]

Hi everyone, I wanted to add a GPU to my Dell R820 server so I removed two NICs that I was never using, left my third NIC in the same slot and installed my P2000 Quadro. The first boot did nothing, believe it was just not posting but I was dumb and never checked the console. Since then I removed the GPU and kept the one NIC I was using in the same slot and I am getting this error below in the screenshot. I am going to attempt to install the other two not in use NICs back just to normalize but really dumbfounded as to why this is happening. Can anyone explain these errors and if I can resolve them?

In the time it took me to write the above, the server booted although the console is still the above. So I guess I have a few questions to anyone that can answer.

1. Are those errors going to cause me issues later on?
2. Can you move around PCI devices without affecting PVE?
   1. It seems like I couldnt do this since I received these errors but since I booted, not sure about this now
3. Despite the mobo or bios settings, does PVE have any issues adding a GPU like I am trying to do?
   1. I wouldnt think so and it makes no sense, just not sure why I couldnt previously, going to try again though.

Most motherboards assign PCI IDs sequentially and adding or removing PCI(e) devices (or enabling/disabling on-board devices) can cause the higher PCI ID of the devices to shift by one. Network devices often get their name from the PCI ID and if they change, you need to adjust /etc/network/interfaces accordingly (lots of threads about Proxmox unreachable after adding PCIe device on this forum).
I don't know what is happening to your system in this case, sorry.
