PCIE Fatal Error

TrueNAS General
1

I am getting to alerts, and I don’t know how to address them. I assume they are related based on the content. I am running TrueNas -Core 13.0-U6-2 on a Dell T330.
The alerts say:
Critical Interrupt PCIE Fatal Err Asserted Bus Fatal Error (slot 2)

Critical Interrupt Fatal PCIe On Bus Asserted

So again I am at a loss. I do have a second empty PCIe slot at 4, will moving it from slot 2 to slot 4 help resolve this. The system has been running fine since I set it up about 2 yrs ago.

Welcome to the forums.

I suggest you move it (whatever it is - you gave us no info) and test the outcome. Come back here and report what happens.

I did switch the card and so far I have not seen any alerts. I assumed that the system info transferred fro the old forum, but it doesn’t look like it. I will fix that soon. The PCIe card was the Raid controller. I put in into the system when I put it online in January. I run 2 additional TrueNAS servers, one as a backup(Dell T30) for home an another in the work environment for file storage (Dell T130)

Must be the PCIe slot, because once moved it is working with no alerts. Thanks for your help.

I did not notice this earlier. You may have another issue - is the card a "
RAID controller" or an HBA?
You need the latter, an HBA, for success in TrueNAS. HW Raid controllers are a no-no for TrueNAS - please see What’s all the noise about HBAs, and why can’t I use a RAID controller? | TrueNAS Community for more info.

EDIT - Forgive me - I just read your system info - you have an LSI HBA, I see.

I’m pretty sure it is not a failure of the PCIe slot but rather something with the PCIe lanes.

Slot 2 is a x16 sized slot that only has x8 lanes, and is connected to the CPU.
Slot 4 is a x8 sized slot that only has x4 lanes, and is connected to a Hub.

I’m not positive but I think you are using the LSI SAS 9300-8I controller, which supports a x8 PCIe lanes. While some cards can work with x4 PCIe lanes, the fact that it did not work in the x16 slot (x8 lanes) leads me to think you should examine the HBA edge connector, made sure there is no extra metal, goofed connections, and inspect the x16 slot with a bright light, and maybe some compressed air.

The other thing is, it could be a BIOS setting. I don’t have that BIOS in front of me but just something you might think about.

With all that said, if it is working, don’t mess with it and break it.

Thanks, I will look into the slots and edges. Thanks for the update.
