Which Hypervisor for TrueNAS Scale?

Nuking, does that refer to placing the motherboard into a microwave and nuking it for 30 seconds? :rofl:

Same. Happy camper now with TNS on metal, using Jailmaker for jails, no apps, and a single Win11 VM.

Why would you run a VM in TN when that’s virtualized itself? Just run the VM on ESXi?!

Speaking for myself, in order to see what other people are experiencing from a user interface perspective. It is difficult to give advice on something when you do not have first hand knowledge. When someone posts a problem, when I don’t know the answer I like to replicate the issue if I can and see if I can provide a good answer to that person. For me it is not about running a VM on TrueNAS for the sake of the VM actually doing anything valuable. And I agree with your sentiment to use ESXi if someone did want to run a VM on TrueNAS while it was running on any other Type 1 hypervisor.

Why are you afraid of that. Its not experimental its in kinda beta state. But you can run truenas without pci Passthrough. There are several good guides which show you how to make it. and if you not running a highavailability truenas you wont eperience and difference.

being able to run it, and it running reliably are two different things

Just nope. You want to passthrough to ZFS.

Well you got it all wrong. I said why are you afraid. And if you can read, I am NOT running it with pci passthrough. Thats why I wrote there is a simple way to achieve it with proxmox without pci passthrough. No need to act like you need to give me a lecture. Beta/experimental is something you never use in production envoirement.

And my version runs reliable and fine since many years.

So you are saying I am lying? Man this forum seams as bad as all the others. Just full of people who know everything better. Yes pci passthrough is better considering speed and other features but its NOT needed as a hard fact. If you talk about professional envoirements its something totally diffrent. But for private use, no.

I think the point of using pass-through is that TrueNAS expects to be in total control of your data. It uses software raid to manage pools and so forth. If you do not pass-through everything and let it manage it, you risk data loss.

Yes you can run it without it, but we’ve seen many people lose data that way. Don’t take this is a “know it all” attitude. Please take it as a “we don’t want you to lose your data” response.

And this is how to run TrueNAS virtualized if you don’t want PCIe Passthrough.

Most people get turned off by the 75% redundancy.

FreeNAS, CORE, SCALE, these are all ZFS and ZFS expects to be in full control of the drives without any intermediate controller sneakily trying to be smart.

For the sake of safety, the general advice here for virtualised TrueNAS is to pass-through the controller—full stop, no excuse, no alternative.

For YOUR data you are free to behave as you wish. Should you ever come to report that you eventually lost your data, you’ll be thanked for the warning… together with a shrug and “we told you so”.

Yeah, no. I don’t know what other forums you might be referring to and it doesn’t matter, but our policy here is not to rubber-stamp whatever bad ideas people claim will be fine.

Literally days after this new forum was opened, a user showed up with a broken system seemingly caused by the latest fad in the world of terrible VM ideas: individual disk passthrough. The opportunities for foot shooting are immense there.

No. Home users are just as entitled to reliable systems that can safely store their data as professional users. There is no rational or moral reason to advocate that other people take meaningful risks with their data.

Do not put words in my keyboard I did not write. Lying implies mala fides; anyone can make mistakes.

ZFS requires the passthrough of the entire controller due to its working: do not pass the controller, your data goes puff. This is a hard fact proved by countless threads in the old forum, and will be proved again in the future: FreeNAS, TrueNAS, CORE or SCALE, is almost entirely irrelevant because it’s a fundamental issue of ZFS.

Your system (allegedly) runs fine? Great, that’s ONE case against hundreds.

Now, you might be a troll since the attitude you have shown is inappropriate for this community; you might just have had a bad day, I honestly don’t care. But if you are going against a well-established (common sense actually) fact, I suggest trying a different approach starting with understanding this community and building credibility.

As of now, your current posts do not help you increase your credibility.

Have a great day.
