I'm using Unraid 6.12.13

 

I've started using Unraid a few days ago, and I was testing a couple of SSDs one SATA and one NVME, alongside a few SATA HDDS. I can spin down everything, except the NVME drive. I made sure to move everything that was in there to other drives, but still the same. the SATA SSD and NVME are in different pools, as standalone devices.

 

I've installed file monitoring to see if I could spot anything open on the NVME drive, but I cannot see anything. I also disabled Docker just in case, also no VMs are running. Still the problem persists.

 

I'm tempted to just remove the NVME drive and see what happens, but could it break something? There are no files/folders left on it.

 

I'm suspecting the NVME drive is keeping my CPU aware, as I'm not reaching low enough C states, and the power consumption is a bit high. 

 

I would really appreciate any directions/help here please. Thanks!

 

this is normal. NVMe have their own power mangement.

They power down instantly after not beeing used. Therefor the OS provides no means to do it manually. It is shown as "running", but usually it is not.

So, the NVMe is surely NOT your problem.

I read that NVME installed on CPU pci-e lane could at time avoid the CPU going into a deep C state level, some people moved the NVME to the chipset pci-e lane and got better results. I just wanted to try that and see if I can see any difference. If there are no files on the NVME, I think it is safe to remove it, right?

I'm afraid you are chasing ghosts...
