How to run TrueNAS on Proxmox?

[@NightHawkATL]

For better Processor access and usage, set the CPU type to host and then it will be hardware rather than software access and processing. I have been running this for a few months and it is solid!

[@christianlempa]

Thanks! I'll look into it

[@Mikesco3]

Not necessarily need ecc, it helps but not necessary. ZFS actually checksums the data as it goes into the drive, so it actually prevents data corruption that would have been an actual issue with traditional raid. The thing with ecc RAM is mostly for example the case of a database where you have large amount of data being transacted in flight and then ZFS is writing that back to the hard drive, but it actually checksums the data as it is writing it. For file storage it isn't that much of an issue.

[@christianlempa]

Thanks for sharing your insights. It's hard to find good technical resources on this topics, some people say it's important, some people say it's not. As I said in my video it's hard to determine how likely something goes wrong, even if it might be just a very rare edgecase scenario, I decided to recommend ECC in my video, because it is useful for filesystem integrity, and it's not hurting anyone to use it.

[@DigitEgal]

@@christianlempa Its hurting guys who dont use enterprise server :D But yes, great to know. So i should run my Databases on my HP380p instead using one of the nodes wich are built with desktop hardware. At 00:30 you tell there are no "bigger" downsides when running TrueNAS on Proxmox. There are a few guys who provide their proxmox/rancher nodes with disc-space by linking them with 10G connections to a single TrueNAS Server. Why do they mostly use a baremetal TrueNAS server? Is it because of performance reason or is there a problem to link the disc-space to another node?

[@user-vw4cg8cy4f]

This video is really really the top of the iceberg. A few crucial thing is missing from this like: - excluding the disks from pve, or else you will wonder why it periodically interrupts disk operations or wakes up sleeping disks - disabling the "use tablet for pointer" as that in itself causes 10+% CPU load on the host side for some reason - disabling "hardware" acceleration of virtIO as this is known to cause problems - doing smart configuration (like APM, idle times) on the host side as the guest won't have access to smart data and alerts - optionally moving the system dataset to the boot disk

[@ozarcgaming]

do you have any links to tutorials on the above suggestions?

[@jackbolder5734]

Thank you. I'll stick with bare metal then. Sounds like this dude just wants us to stick his finger up our po poos.

So true he don't even set the guest OS right.. XD What he should also really have done is change the cpu type to host so that the VM can use all the instructions the cpu has...

[@christianlempa]

Thank you! Glad to hear that :D

[@LampJustin]

It actually is impossible to really pass through the drives itself (if you don't count NVMe drives) as what he's doing is using the drive as a backing store for a virtual drive with the size of the physical drive. You don't get any of the benefits that would make sense for zfs / TrueNas like smart or temperature sensors.

[@theitalian94]

@@LampJustin is this fact? SMART won't work with this passing threw method? that would be a shame, I didn't had time yet to check if SMART Values are showing up or not ...

[@LampJustin]

@@theitalian94 that's definitely the case. You either need to setup monitoring on the Proxmox host itself or get a SATA/SCSI controller and pass it to the VM.

[@christianlempa]

The truenas VM is unfortunately not able to see the smart values, but you can still check it on proxmox.

[@pobertubbesing]

Excellent video. Thanks for elaborating on how to set up the physical drives independently with the Truenas VM. Personally, I would instead use RaidZ and have TrueNas control the RAID System rather than having to use a controller to manage the hard drives. I'm sure you would sacrifice a little performance. However, everyone's use case can be different.

One little thing (and I've been seeing this in a lot of similar tutorials), but "SCSI" is pronounced "Scuzzy". Probably not something that comes up a lot if you didn't work in enterprise storage in the 90s, so I'm not surprised that nobody else has mentioned it

[@bertnijhof5413]

Note that the disk serial number results for some nvme devices in ridiculous long serial numbers, so I prefer to use the UUID of disk or partition for the creation of the datapool. I always split my HDDs in 2 partitions, the first ~40% faster partition is for the VMs and the remainder for the other stuff. As a consequence the SSD I use for caching has four partition, 2x cache (L2ARC) and 2x log (ZIL).

[@EdwardPike]

1. Thanks! 2. First time NAS and ProxMox user. 3. I added 2 HDDs to a new install using your method. TrueNAS says they have same serial number. I drilled down in the "Disks" list and they both have empty serial numbers (which makes them equal I suppose). I will now look back at the QEMU command that added them and see if something there about serial numbers.

[@flakmoppen]

Same here. Did you manage to find a solution to this? EDIT: I managed to find a solution. Go to your proxmox shell and do: nano /etc/pve/qemu-server/[ID-OF-YOUR-VM].conf Find your SCSI device. (Mine was "scsi2: /dev/disk/by-id/ata-ST5000LM000-2AN170_WCJ6B8PP,size=4883770584K") Add your serial number at the end. (Mine now is "scsi2: /dev/disk/by-id/ata-ST5000LM000-2AN170_WCJ6B8PP,backup=0,size=4883770584K,serial=WCJ6B8PP") Hope that helps :)

I know this comment is very late but not all motherboards have SATA as something you cannot passthrough, some boards show their sata controller as PCIe devices/chipset and allow you to passthrough them to said VMs (works for me, however it doesn't mean that It'll work for everyone)

[@JanVanhumbeek]

I just did approximately the same set-up, but I noticed that you don't have IOMMU enabled on your server? If you enable IOMMU in your motherboard BIOS, you're able to pass through the onboard SATA controllers as PCIe devices to your VMs (in this case TrueNAS). This gives the VM hardware-level access to the controller and all attached disks, and thus means more native performance + being able to do S.M.A.R.T. tests on the disks.

[@christianlempa]

Oh that's nice to know, let me check that! Thanks mate 😍

@@christianlempa Just checked your motherboard manual, I would enable these settings: Advanced/CPU Configuration/SVM Mode Advanced/Onboard Devices Configuration/SR-IOV Support And then look in Advanced/AMD CBS subsections for: IOMMU PCIe ARI PCIe ACS

[@panoshountis1516]

Very detailed and helpful. Just wondering, is the raw HDD pass-thru to TrueNAS the recommended option or the only option? I mean, I am contemplating whether it would make more sense to create a RAID5 pool via m/b RAID controller and pass-thru the disk to TrueNAS instead. Would that be an option? I am using a Synology DS920+ as my main NAS Server. I am considering running a TrueNAS VM on Proxmox as a 2nd level level of data backup.

[@nalle475]

Nice one again. 👍 I have been running Free/TrueNAS on bare metal for years and love it. Tried it firs on consumer grade HW but it runs much better on a really old Proliant G5. I think its the ecc memory that boost the performance. Ecc memory and battery helps when things go sideways - as it usually do at som point. I also have virtualization TrueNAS servers from time to time. My settings are different but generally the same as yours. I have been thinking of moving my production TrueNAS to Proxmox just to have all machines running Proxmox make some work easier. I run 3 Proxmox servers and a ProxmoxBS and then the TrueNAS. I have 4 HP servers in my rack and one self build. I strongly recommend real server HW due to performance and cost. SAS is superior but SATA is cheap - your choice. I will not recommend the Scale at this time due to the weak performans as to date (see Tom Lawrence videos)

[@congenio]

This does solve one part of the problem that Proxmox is not so great for providing space if you do not want to separate the file server (or NAS) and the VE engine. But one problem remains: the TrueNAS VM cannot be snapshottet, since it has pass-thrus. Also, this is a viable solution only if you deploy new hardware - you are in trouble when you try to migrate a huge array that is on an existing RAID, probably also encrypted. I have yet found no way of doing this - if Proxmox mounts the device, it must also provide the shares (which is not very good at). Every other solution carries over the control to an embedded VM, which can then not be snapshottet like other VMs. Containers are not a solution for this, either.

[@THEMithrandir09]

Did you try to install a VM into the TrueNAS managed storage? Or do you just provide the space managed in truenas to the VMs as additional storage, e.g. as a remote /home?

Most VMs i currently use are fine in Scale with Apps, Plex, Nextcloud, but sometimes app dont fit and therefore virtualiszation would be ideal. thus i never worked with proxmox and i think truenas scale as main OS should be quite capable on Vms too + cloudflare tunnels for all of the apps to be accessible

I like these videos, but they'd be way more useful if you said more about the "why" behind the procedures. Yes, it's possible to virtualize TrueNAS, and you've done a great job of telling us how to do it. But what, if anything do we actually gain by doing this? What's the reason? ....because you can? It seems that the more roles / VMs / functions are added to a single physical machine, the more exposed it becomes in the event of hardware failure. If my production server, NAS, gaming rig, etc., are all in the same machine, when something goes physically wrong, instead of just losing one, I lose all. Of course, if the point is just to use the platform as a learning tool, that makes total sense, and it's probably a great idea to have one or more 'disposable' machines laying around for practice and learning. Great tutorials. Thanks!

[@patriquesimoes7137]

Can this be done with a LXC container in Proxmox instead of a virtual machine?

[@heliwrsfoestuff5913]

I built my current Proxmox server around AMD 3400G CPU, before understanding the risk associated with non ECC memory. However, I agree with Michael that for home users it's not so much an issue. Plus one should not rely on ZFS or any RAID system equivalent for backup. For that reason I also use Backblaze, which has very reasonable rates for offsite backup storage. Then in the unlikely event that my data gets corrupted, I can rebuild it. I am using Alpine Linux/SMB LXC container as a file server right now, but I really liked TrueNAS (was using my Proxmox box as standalone TrueNAS server) and will most likely switch to a TrueNAS VM in the near future. But LXC containers are a whole lot of fun, and very efficient.

Sounds great! Yeah I don't think that ECC is always needed, however I would still recommend it generally. But I can see that it's not a must have for every setup, especially in a home server.

Trouble with Drive stats Visibility and SMART in TrueNAS VM on Proxmox I had set up a TrueNAS VM on Proxmox, utilizing a RAID Z configuration with four 2TB HDDs. Here's the catch: three drives are directly connected to the motherboard, and I've added a PCIe SATA expansion card for the fourth drive. However, I've encountered a snag-I've noticed that not all drive information is visible in TrueNAS, and the SMART options aren't working either. Given that I'm now using this server for work purposes, I'm feeling a bit uneasy about the situation. My SMB shares are functioning correctly, and backups are happening as expected. However, I'm concerned about potential drive failures and whether I'll be able to manage replacing a failed drive without risking data loss. Is there a way to address this issue without redoing the entire setup? Any guidance or suggestions on ensuring drive visibility, SMART functionality, and data protection would be greatly appreciated. Thanks in advance!

Hello @christianlempa! Im running truenas on proxmox, but i need to changee the motherboard, could you make a tutotial on how to migrate everithing to the new sistem without loosing data?

[@匀匀云]

Thank you for the tutorial, Now TrueNAS Scale is getting better ，should i still install TrueNAS Scale on Proxmox , or just installed on host and use VM\docker on Scale?

[@christianlempa]

Good question, it depends on what you want to do with it. If you're running a single server environment, I guess it's okay to run TrueNAS on Proxmox, because Proxmox is far better in managing VMs.

[@匀匀云]

@@christianlempa yes ,you are right. i try to use vm\app on scale , Proxmox is far better

I cant get my HBA controller to passthrough to me TN VM. The drives are all listed under the node level and show up using lsblk. IOMMU is enabled in the BIOS. It is an LSI 3900 16i on a ROMED8-2T. Also couldnt pass the native on board sas controllers to pass through either.

Hello! great video! I have an question. Isnt the best way to use the /dev/sda1 /dev/sda2 and etc identification to passthru the hard drives from mainboard? in case of failure of hard drive you can offline it from truenas, power off the whole system and replase it to new one. you plug new hard drive and mount it in truenas and thats it. otherwise you must write the new id of new disk in proxmox at first.

[@christianlempa]

You should use the IDs instead of sda, sdb, .. because these could change under some circumstances, so better go with the ID to avoid any issues.

[@MrMkrb84]

@@christianlempa thank you!

[@jonathanzarka6914]

hello thx for this video very useful.However if one disk fail how can you make to change It because I suppose you have to declare un new physical volume in proxmox is that easy

Is running without ecc memory really something I should avoid? I have a cool build for a sever in mind and it doesn’t support ecc memory.

[@christianlempa]

No, ecc memory isn’t as important for homelab as it is for enterprise. You’ll be fine without it

[@Glatze603]

Hi, how is it possible to automate backups of the truenas vm without the data-disks?

[@Glatze603]

Got it - there is an option in the drive-settings of the vm :-)

[@taipanino]

hi do you have any idea if the passthru would work with hp 530sfp+ card cause i cant get it to work

[@jackmclane1826]

Careful! There is a difference between plain ECC and registered/buffered ECC memory! Just ECC can also run on some consumer price range machines. AMD Ryzens have unofficial support for it. It's in the chip but AMD didn't deactivate it and doesn't advertise it. It should work but it may not. No guarantee for that. And some selected Intel CPUs also can have ECC. Both will only work with unbuffered/unregistered ECC. Registered/buffered ECC is a thing for high end professional server hardware only. Those machines that support over TB of RAM. It's not a thing for home players.

[@drachenfliger1368]

Now, there is a confusing topic to me, which is File system, you mentioned that truenas(core) had its own software raid, proxmox uses a software raid aswell, but what about the hardware raid card in a server how to configure it correctly then?

[@rockymarquiss8327]

Trunas core is best run (IMO) in a virtual environment. When I looked into it in the past they insisted that you're supposed to boot from a thumb drive. I find this mentality insane. How often have you had one of those fail? Alternatively you could put an extra drive that will be grossly underutilized. They aren't very reliable to put it mildly. With virtual machines you can have that boot drive defined as a small drive to boot from - using resources much more reliably and effectively.

[@Mikesco3]

There is a not too complicated way to add cockpit to proxmox and manage ZFS and sharing that way also

[@LampJustin]

Yeah definitely much more recommend... Running your storage as VM with not a lot of RAM Cpu and not even "real" disks is just stupid tbh. First he didn't set the right OS, TrueNas Core is BSD based, but that doesn't really matter. What is a lot more important is that he left the cpu type as kvm64, which is such a noob thing to do. With that you just don't get access to all the needed cpu instructionsets that TrueNas will make use of. Cpu utilization will be higher and speed lower. Also you don't want to pass through disks the way he does it, all the smart info, temperature and so on just won't get passed through as it will just emulate the disk within the virtual Virtio SCSI controller and use the drive like a raw image.

[@LampJustin]

@@ianballester4672 sorry but I don't know what you mean??

[@dbadovsky]

@@LampJustin Have you any other way to passthrough onboard SATA controller to VM? For me, I've passthroughed onboard SATA controller but still don't see SMART info in truenas. And what CPU type should we use? For example, I have options "IvyBridge", "IvyBridge-IBRS" and "host" Thank you!

[@LampJustin]

@@dbadovsky hm that's odd, that should definitely work. Are you sure the passthrough works as expected? Do you see it in the VM when doing a lspci? As to the cpu configuration, if you're not using a cluster with different CPUs ( 2670 / 2690 for example) you should use host as that will give you all the cpu instructions within the VM resulting in the best possible performance.

[@dbadovsky]

@@LampJustin Thanks for the answer! Well, I see my disks inside vm and I can import the pool, it works great but the only issue is that TrueNas can't see smart results. I also noticed one thing: this iommu group includes 2 devices: SATA controller and SMBus controller. They are marked as #2 and #3. Seems like I lack something.. I'll try to look for it in BIOS, maybe any feature is disabled..

[@derekdresser9214]

Great video, Im a bit late to the game but I have watched quite a few now. The more i watch the more confused i get. Ive had 2 low end servers over the years and recently wanted to update it. First server was WHS second was just an old PC running windows. Anway, i want a place to hold my files and Plex and perhaps try a few virtualizions. I want to use my old hardware to do this (4th gen i7) Now i watch this and learn about needing ECC RAM and i dont know what to do. Honestly it all just seems too difficult

[@christianlempa]

Don’t worry about ECC in a Homelab, will make your life easier :)
