Installing a new network adapter - encountered an uncorrectable I/O failure

TrueNAS General
1

Hello all.

I am running Truenas scale on a computer, with Home Assistant as in a VM. I also run a few apps (jellyseer, pi-hole, ollama) on the same system.

I have had a bunch of connectivity issues that i think are related to my lack of knowledge and experience with bridging (and networking in general). I have some stability issues, cant seem to connect via app (on mobile or pads) and so I thought buying a new network adapter, as i did USB controller, would solve these issues as the VM would get its own network cable.

So first i bought a few silly-cheap ones off a second-store site. These were TP-Link TG-3468 - networkadapter - PCIe - Gigabit
When installing i got the message: Warning: pool “boot-pool” has encountered an uncorrectable I/O failure and has been suspended

Ok, i looked into it and other people had issues with it as well. It looked really complicated to get those to work, so I used AI to ask for compatible plug-and-play network adapters for Truenas Scale.

And so I bought a brand new Intel I210T1 Ethernet Server Adapter, because according to the AI this was a plug-and-play solution to (all) my problems :slight_smile:

However, it arrived today in the mail and i got the same error when booting:
“Warning: pool “boot-pool” has encountered an uncorrectable I/O failure and has been suspended” –

Does anyone has any idea what im doing wrong? Can it be the PCIE-slot on the motherboard that is not working? I’ve now tried with two different cheap TP-Link TG-3468 and one Intel I210T1 Ethernet Server Adapter and they all get the same error message.

When I shut the computer down, and remove that single hardware, it all boots up again just fine. The other PCIE slot has a USB-controller that is passed through to Home Assistant, and it was literally plug-and-play no issues.

Any help is much appreciated,

Wish you all a wonderful day,

Ps. Ive read a ton of other threads on the issue but they all seem to be related to boot-disks. This does not seem to be boot-disk related, as everything works wonderfully when the network cards are removed

Is your boot device an M.2 NVMe SSD? Consult your mainboard manual. Probably it shares PCIe lanes with the slot you are using for the network card.

There might be some magic setting in the BIOS setup, or use a different slot. Or, last, if the M.2 supports both NVMe and SATA, try an M.2 SATA SSD. Then again that might share a SATA port with one of your disk drives.

So consult your mainboard docs or manufacturer support.

Thank you for your reply.
Yes the boot device is an M.2 NVME SSD. I have looked at the mainboard manual, cant seem to find what im looking for…

The computer is a HP Prodesk 600 G4 sff. I will ask the manufacturer if they might assist in this.

Thanks again for your reply.
