Add NVMe to Single Disc

TrueNAS General

You’d have to supply the verbose option to see if that is indeed the other device.

lspci -v without the “grep”.

Ok, here we go:

The other one:

        Subsystem: Samsung Electronics Co Ltd NVMe SSD Controller 980

        Capabilities: [188] Latency Tolerance Reporting

        Kernel modules: nvme

Both take different IRQs - but i am still insecure, if those a different NVMEs.

Nowhere in the BIOS is there a RAID/AHCI option? (Don’t change anything yet! Just check.)

Is the server connected to a monitor and keyboard? Would it be possible to boot into an Ubuntu live ISO to see if it will show the device with nvme list?

There is such an option, but its still in AHCI, as far as i remember. And, i didnt go into the BIOS until today, to see, if the NVMe is detected there.

I will create an USB thumb for the linux live system and check.

A strange thing, which happened today was, i had a talk with my colleague on work and he sloppily mentioned “Why dont you take the card out, during the system runs and reseat it? Normally the ports are hotswap-able”

Did it as mentioned - the card was recognized and i was able, to add it to the pool as a mirror.

Might it be possible, that TrueNAS marked the whole port as “defective”? But why?
