Hello,

 

I just build my first Unraid server with a Nvme Crucial P5 500Go and i have a problem, it is well recognized but after a while it disconnects and disappears. I have to restart the server to find it. So my server is absolutely not stable and I do not know what to do.

 

Did I miss something ?

 

My configuration :

Gigabyte B550-DH3S

AMD Ryzen 3100

GTX 1660 Super

Post your diagnostics the next time this happens before you reboot

I'm a beginner in Unraid.

What diagnostics and where to find them ?

Tools Tab.  Diagnostics.   Post the entire zip file to your next post here

My server just crash, i recovered the log before reboot.

No SSD recognized at restart.

Problems started with an IOMMU related error:

 

Jul 24 03:46:50 Unraid kernel: nvme 0000:01:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0001 address=0xbe75f000 flags=0x0000]

 

That resulted in the device timing out:

If you don't need it you can try disabling IOMMU, BIOS update might also help.

Is the IOMMU is needed for hardware transcoding with plex or handbrake ?

I understand it was only for the passthrought.

BIOS was updated at the first launch
