TrueNAS not booting due to NVME SSD

Hi all,

I am having a bit of a unique (I think) issue, where suddenly, after updating from 13.0.1-U4 to U6, my TrueNAS Core was not reachable. The console showed the following error message:
pxe-e61 media test failure check cable

I think I found out how this happened, quite funny actually.
  • I used to have two USB thumb drives as boot mirror. One failed pretty quickly.
  • I bought an NVME SSD (SATA is not possible, since I need all SATA ports for hard-disks, and the m.2 and one sata port share the same bus or something like that). I detached the failed USB and replaced it with the SSD.
  • The system ran like this a couple of weeks, maybe even survived a reboot.
  • I then thought that mixing SSD and USB drive in a mirror is no benefit (probably even a risk) and i detached the USB drive.
  • The system ran fine for months like this.
  • Enter 13.0.1-U6: After updating and rebooting, I suddenly have as only boot medium an SSD over PCIe with incompatible BIOS settings (UEFI vs legacy) and am not able to boot.

Can anyone confirm, that this indeed is the issue. If I researched correctly, when using a boot medium on PCIe, BIOS needs to be set to UEFI mode and so does the installation of TrueNAS, which it probably is not (initial installation was 7 years ago).

What are my best next steps? Is there any possibility to fix this with correct BIOS settings to the PCIe firmware or boot options? Or should I just reinstall TrueNAS and reload my last config? What do I pay attention to when doing this regarding BIOS settings, installation settings and rereading the config file. I don't recall if the system dataset was on my boot-ssd or on my jail ssd-mirror. Would this be an issue, when the boot ssd was wiped during installation?

Thanks in advance,
