Hi, I have built myself this first unraid machine just a over a week ago. I have installed Fix Common Problems plugin as advised and it started giving me this error about Machine Check Event detected on server. I also installed NerdPack with mcelog, but it seems that mcelog isn't working correctly since its displaying an error that I googled and it seems to be an issue with mcelog itself. While the main issue in Fix Common Problems seems to appear even when the array is off, though I only discovered when first running the array and I presume then FCP ran automatically.

 

This is my first time building a server of any kind, so I don't know what the issue is, the syslog txt in this zip seems to have some Hardware error happen regarding CPU but I can't understand what it means. Only thing I can add regarding CPU is that I only connected the 8-pin CPU power cable to the Motherboard and not also the 4-pin CPU power slot next to it because the PSU didn't come with a 4-pin CPU cable, though the manual for the motherboard says that the 4-pin connection is optional.

 

So far I only did pre-clear on my 2 HDD disks (pre-clear test mentioned no errors or issues) and after then put them in the array and have them parity sync, later I disabled the array to add a pool cache of 2 SSD NVMe's. Haven't yet actually set up shares or moved any data in.

 

CPU error in syslog:

Some combinations of hardware will issue an mce during processor initialization.  This is happening to you and is nothing to worry about and can be safely ignored

Oh, that's great. I was worried I mucked something up while building the server, considering that was my first time I built a PC completely without anyone else's help.
