Top shows this - Who is that "kworker/12:1+pm" guy?

CPU Govenor is set to Performance. I'll pull the Inateck card later and review core load.

That points me to the Inateck USB controller I added recently.

safemode, no gui. Array offline. Same situation one core at 100%, all other cores idling.

I didnt change anything in my Plugin mix, however to narrow it down, I did following earlier: removed all the Dynamix and a few others Disabled VMs and Docker rebooted and kept the array stopped for a few mins Still, one core at 100% Have the array now online again, docker and VMs enabled, no VMs running. Not sure how to trail that @JorgeB

don't think htop adds a lot of detail here: To add: I changed from a Ryzen Board to Epyc a few days ago and added a RX560, Fenvi T919 and Inateck USB controller card. Non of the cards is being used atm, all VMs are off.

Same situation, though the 100% load jumped to another core. Even before I start the array.

Removed the plugin, still core 8 at 100%. Can we dig further? Happy to help / learn how to.

right ... I didn't think that far this morning. Thanks @JorgeB Latest diags are attached., I disabled VMs, Docker, stopped the array and restarted the host. Still one core remained at 100%. The 100% load jumps from one core to another after each restart. ryzen-diagnostics-20211122-1253.zip

One of my CPU cores is stuck at 100%. No Backup / Parity check running. How can I find out which service is triggering this? I have one VM running, but that is pinned to different cores. Any advise?

if you want a correct answer send a message to the ASRock Support through their Website form. And I suggest to stick to the memory they have in their QVL. Your memory is OC Memory as I see it, not sure if that and the XMP profiles work on that. If you want a safe and stable bet, go with the memory I used, see 1st post.

I'd say you get better hardware for 600 USD, although this can be a starting platform for you. Do you need the P2000 for anything specific? How much storage will you need? Do you plan to use VMs / passthrough hardware to VMs?

Is this plugin still under active development?

yep, overkill. And that's pretty much the case for 90%+ of the builds here, ... hence ignore the first line. We all like decent hardware, dont we? Regarding NVME caching. I'd go for two similar SSDs for a Raid 1, or 4 similar for Raid 0+1. The latter is my config - 4x 960GB in Raid 0+1. I have my appdata on cache only (and backed up to array). Depending on your share config you can of course direct services to specific shares which dont use the cache. I am doing this for one of my Backup shares. I would review the drive setup and consolidate there if you have budget left.

HDDs, for example Seagate BarraCuda Compute 4 or 5TB. Or Seagate SkyHawk (specifically certified for 24/7 operations, 3.5“), the latter has a slightly higher power consumption. 3000G should be ok for your purpose. If you can / want afford a 4 core 35W cpu I‘d pick that. But there are not many options, like Ryzen 5 PRO 2400GE or 5650GE. Alternatively and if your bios allows pick a 65W cpu and set it to 35W through BIOS settings. Drawback is, that you noticeably limit the CPU performance for some use cases such as transcoding. There are also much faster PCIE 4 NVME SSD with low power consumption available like the Kingston KC3000 PCIe 4.0 NVMe SSD 512GB. PCIE 3 NVMEs consume a little bit less, though they a slower. Watch out for SSDs with enough TBW, depending on your use case and expected life span.

Good combo. Could be optimized with a 35W CPU, Noctua redux fans and 2,5 inch disks if you want to lower the power consumption.

How much is „low“ power from your perspective?

Die Bauteile sind nun ausgebaut und Details habe ich hier gelistet:

I am selling Board, CPU, Memory and Cooler from my current system since I upgraded Board and CPU. Since I am living in Germany I'd prefer to sell within the Country or the EU, assuming that International shipping might be to costly. However, I am free to explore options, especially for the CPU since it is rare. CPU: ~ sold Ryzen 9 3900 12 Cores / 24 Threads 65w OEM Systembuilder Model (100-000000070). I bough the CPU brand new a year ago. It was never overclocked, but mostly set to 35w or 45w through BIOS settings. I personally think this is one of the best AMD CPUS, comparing watt vs. cores. Memory: ~ sold 2x 32 GB Kingston KSM32ED8/32ME DDR4 3200 ECC Memory. Also 1 year old and 100% compatible with the Board and CPU, since the config has been running rock stable since day one. Board: ~330 Euro ASROCK Rack X570D4U incl. ATX shield. Bios and BMC are up to date so the Board can also take Ryzen 5000 CPUs. Cooler: ~30 Euro, optionally included with CPU Noctua NH-L12S, stock config and fits perfectly on the Board. Details about the config can be found in this thread, where I documented the build process. Questions? Let me know Pictures:

Werden SSDs als Array disk offiziell unterstützt? Ich hatte mal gelesen, dass dies nicht so ist. Hat sich daran mittlerweile geändert?

Nice piece of hardware to play with, and I doubt this can be serious foundation for an UnRaid installation. For the limitations the price is too high from my view. Meanwhile, check dfi.com @Phantomwalker, they make nice embedded hardware. A good overview of new released embedded hardware is this page.

or create a share specifically for VM vdisks, and set the cache mode for that share to "Prefer".

@onadeathstar that's good value for money, and you get SMT which will give you 32 threads.

you would need a dual G34 board like this beauty Afaik the CPUs do not provide SMT, So 24 physical cores = 24 threads. But with a 6366 HE (85W) you can get a 16 cores CPU for less than $40/50 so could build a decent 32 core system that also support PCI-E 2.

Idle / Watt is also a concern for me. Hence I decided for a Ryzen 9 3900 (65W Systembuilder version) a year a gear. A nice CPU, with plenty of power and very efficient. Can be set to 35W / 45W / 65W and you get the performance you need, however - the limited PCIE lanes are a deal breaker if one wants to play with hardware passthrough. I realized that recently and will replace the good board + CPU with an EPYC system. I think the Ryzen Threadripper consume to much, or a 65W version would be nice but that does not exist. So I decided for a 7232P CPU (8C / 120W) and a Asrock Rack RomeD8-2T. Plenty of PCIE lanes and a CPU which has enough power to serve today and does not burn a hole into my wallet. Once the 7272 or 7282 will become cheaper on ebay I'll get one but for now I think I addressed my needs for more lanes, on a platform that allows to grow for the next 3 - 5 years. Ryzen Threadripper is awesome, when electricity costs nothing and when you really need a "V8" block. Just my two cents
