Update: Installed the two Samsung SSD 990 Pro NVMe. So far no issues. Temp is 32 Clesius. No Error Information Counts. Currently the parity check is running. I post another update in a few days. Still a bit disapointed about the whole circumstances but I'm goging to continue with Unraid anyways.

I've ordered a Samsung 990 Pro 2TB NVMe. Should arive next week. Will perform some test with Unraid and post the results.

@JorgeB first of all, I want to thank you for your time and advise. It is much appreciated! I tried to choose my setup with a lot of thought (e.g. the Kingston NVMe's have one of the highest TBW (2PB) compared with other similar products), but now I have to face the pontential outcome, that there is nothing I can do to get my setup running with Unraid. And besides this forum (where you were the only one trying to help me) I have no idea who else I can talk to. Again, with all the different tests, I would conclude, that the hardware setup by itself is not an issue. I would love to learn, what's going on under the hood, (e.g which command are causing the Error Infromation Log Entries, what invalid field there is, or what is causing the NVMe to stay permanently in the highest power state), but there is apperently nobody around to help analysing the problem. Not sure if the Unraid Team is interested at all. That leaves me two possible ways forward. Change the hardware setup (on my own costs) or change the OS.

Test with Parot P300 did not show the temp issue so far. I have to run the parity process right now, but the NVMes behave as expected. Still I would be curios, what the OS does (e.g. what command is it sending to the NVMe) to keep them in this high Power Status. I've spent 300€ for NVMes which are apparently not compatible with Unraid. If I now buy two Samsung SSD 990 PRO I am not sure if it will operate as expected. Very unsatisfing. Is there a compatibilty list available from UNraid team?

Yes HDDs connected all the time. For TrueNas I added a SATA SSD for the installation too. The error issue occurs only under Unraid, but it must have something to to with the state of the array, as I sometimes see the counter rising and sometimes the number is stable. I have seen this posts as well. Unfortunately they don't come to a conclusion... I bought two cheap NVMe drives (Patriot P300, 128GB). I'm going to test these drives with Unraid. Probably tomorrow.

So I have an update on the situation. After installing TrueNAS-SCALE-24.10.2.1 and setting up the storage 2x HDDs and 2x NVMes. The issue does not show! Summary: Unraid 7.0 -> NVMe getting hot Unraid 7.1 -> NVMe getting hot Ubuntu Desktop 24.04.2 LTS -> NVME no issue TrueNAS-SCALE-24.10.2.1 -> NVME no issue Could you elaborate what kind of Bios/firmware issue you're thinking of? Any tipps which settings I can try changing? Or what can only happen with a specific kernel series?

You were right about me using Unraid 7.0. I did an update to 7.1.0-rc.1. The NVMe behaves still the same. I'll try TrueNas as well.

I don't have knowledge about that. I simple tried it with Ubuntu Desktop 24.04.2 LTS because it was the first thing what came to my mind. How can I find out about the kernel?

Of course Unraid only reports what's going on on the device. Same does the smartctl (SmartMonTool). My take on that is, that it must have something to do with the OS, as it doesn't show at all in an Ubuntu evnironment. I would guess, that the OS continuosly sends commands to the device, what prevents the device from going into powersaving states and therefore creating the high temperature. By the way, the device doesn't show any other activity in Uraid or smartctl. The value "Data Units Written" nor "Data Units Read" aren't changing where as the "Error Information Log Entries" keeps going up.

Hello all! I'm pretty new into Unraid, but figured to use Unraid for my next NAS build. I built a new system and setup Unraid and I was confident to buy the license. I like the features and the apps and plug ins. I was almost ready to move all my data to the new build, when I found an issue with my NVMe's. First here is my hardware setup: Mainboard: ASUS Prime H770-Plus CPU: Intel Core i5-14400 RAM: Crucial Pro DIMM Kit 32GB, DDR5 NVMe: 2x Kingston FURY RENEGADE SSD 2TB, M.2 2280 PCIe 4.0 x4 HDD: 2x Western Digital WD Red Pro 16TB I installed the latest version of Unraid, used the two Kingston NVMe's for cache pool and the two WD HDDs for the array. The system was up and running for more than a week, everything stable and working. Than I wanted to take a look on power consumption and temperature. I found that the NVMe's were realy hot (around 75 Celsius) and also the power draw was hefty. I tried a lot of different things (see a post in the German Sub Forum). Long story short: For comparison I booted from a live linux (Ubuntu) with the exact same hardware setup. Here the NVMe's only reached 30 Clesius and the power draw was significantly lower. When I disconnect the SATA HDDs and boot Unraid, the temperature of the NVMe's was 30 Celsius too. But as soon as I connected the HDDs back, the temperature of the NVMe's rises to above 70 Celsius within minutes after booting. Another weird thing I noticed was the "Error Information Log Entries" value of the NVMe's. I retrieved that through smartctl on the cli. When I boot the system from my live linux (Ubuntu) this value does not increment at all. When I boot Unraid without the SATA HDDs connected, this value does not increment at all. Only when I boot Unraid with the SATA HDDs connected this value is incrementing continuosly. Increamenting roughly by 30 every minute. See the screenshot above. It apears to me as if the operating system is trying to repetively send varios commands the NVMe with an invalid field. Unfortunately I couldn't find any information what is doing that or what invalid field there could be. I am at my wit's end and have no idea what else I can do to get to the bottom of this. I can provide more information about the setup and the system if it would help anyone. Otherwise I am desperate for any tips. Especially since the Unraid license is about to expire and I would only buy Unraid if I can get my setup to work.

I stumbled into this posting, as I experience a similar issue with my nvme drives. What I found out so far ist, that when I disconnect my HDDs and start Unraid, the nvm drives stay at 30 Clesius. As soon as I connect two SATA HDDs to the system, the temperature of nvme drives raises to 70 Celsius. Array Offline/Online doesn't make a difference. And there is no load at all. That behavior is perfectly repeatable.

Soweit ich das jetzt beurteilen kann, verhält es sich unter Ubuntu und Unraid (ohne HDDs) identisch. Die Temperaturen bleiben stabil. Schließe ich die HDDs zusätzlich an, kann man sehen, das die Temperatur innerhalb weniger Minuten bis auf 75 Grad hochlaufen. Ein anderes Board steht mir momentan leider nicht zur Verfügung.

Danke für den Tipp mit dem SATA Modus. Ich habe das nocmal überprüft und es läuft alles so wie erwartet. Die beiden HDDS (sdb und sdc) lufen über SATA und die beiden NVMe's über pcie.

Nachdem ich im Ubuntu Setup nichts verdächtiges feststellen konnte, habe ich wieder auf Unraid geswitched. Zufällig habe ich nur die NVMe's eingebaut aber noch nicht die HDDs. Überraschenderweise war die Temperatur den NVMe auch jetzt nur 30 Grad. Also habe ich nun auch wieder die HDDs angeschlossen. Nach dem Neustart war die Temperatur der NVMe's wieder bei 75 Grad. Ein Stoppen des Arrays machte auch keinen Unterschied. Was mir jetzt auch noch aufgefallen ist, ist dass der "Error Information Log Entries"-Wert laufend hoch zählt. Ich habe die Stoppuhr mal mitlaufen lassen. Der Wert geht pro Minute um 30 hoch. Das passiert nicht, wenn ich die HDDs abstecke. Parity Check ist nicht gelaufen, und es macht auch keinen Unterschied ob das Array Online ist oder Offline. Das komische Verhalten der NVMe's trit nur auf wenn ich die HDDs anschließe und nicht wenn ich sie abstecke. Kann mir jemand einen Tipp geben wie ich die Log Entries auswerten kann, bzw. was diese verursacht? mfg Thomas

So ich habe nun versuchsweise Ubuntu Server installiert. Bios Einstellungen unverändert zu vorigem Setup mit Unraid. Die Kingston NVMe fühlt sich kühl an. Kein Vergleich zum ersten Setup, da verbrannt ich mir die Finger. Ubuntu Server: smartctl zeigt mir eine Temperatur von 30 Grad Celsius an (siehe Screenshot 1) Temperatur sensor 2: 80Grad Celsius (bin mir nicht sicher was der Unterschied ist) Im Vergleich dazu ein Screenshot von meinem NUC14: Leistungsaufnahme hab ich übrigens auch gemessen (mit einem Shelly Plus Plus). Das Ubuntu Setup braucht im Leerlauf 18,6W. Ohne Monitor und Tastatur/Maus Die Unraid Installation mit HDD Spin down war bei über 33W. Das muss ich aber nochmal verifizieren. Irgendwelche Tipps wie ich weiter analysieren kann? mfg Thomas
