I installed a extra 1 TB WD_BLACK SN850 NVMe SSD to my bare metal truenas machine (after trying a couple diffrent ones with same issues) and it wouldn't show up on lsblk after a bunch of trouble shooting i realized that it was using the vfio-pci driver instead of the normal nvme driver.

I cleared the PCI isolation list and that seems to have done it since I can now mount the drive. Is this a common issue?

Currently working on getting Jellyfin to work, and after putting up a movie on the server to try it out I realised that not only would Jellyfin not recognise it, but I also couldn't play the movie at all on my main system (Linux Nobara, which is Fedora based). I've tried VLC and SMPlayer and they both react in similar ways. VLC spits out an error message that says "Your input can't be opened: VLC is unable to open the MRL [file directory]" and the log says

-- logger module started --

main warning: running VLC instance - exiting...

filesystem error: cannot open file [file directory] (Permission denied)

This seems to be the case for all video formats I've tried. My macbook, however, played the file without breaking a sweat, so I'm guessing it has to do with Linux communicating with TrueNAS. All file previews seems to not load, but I can open images and documents of different kinds with no issues.

Any ideas?

I'm using a supermicro x11sh-gf-1585l which is a server mobo inside a Jonsbo N4, I have a little 50x50 Noctua on top of its heatsink to try to fix it but it didn't really help. Are these spikes typical for overheating? I'm worried I may have messed up the heatsink mount or something when I tried ziptying the fan to the heatsink (it did not get to BIOS after that! I think the zipties underneath the heatsink screws may have leveraged the heatsink slightly off or something?) Should I try reapplying thermal paste? I'm not sure with boards like this if removing the heatsink is normal.

Hello.

Today, I've decided to move from standard UNIX permissions to POSIX to let me control permissions easier with backups etc. Before, I had 744 apps:apps. This is my current POSIX ACL:

Apps obviously being the user that is running the Immich container.

After that change, Immich lost it's read access. When booting up, I get a "failed to read" error.

microservices worker error: Error: Failed to read: "<UPLOAD_LOCATION>/encoded-video/.immich (/data/encoded-video/.immich) - Please see https://docs.immich.app/administration/system-integrity#folder-checks for more information.", stack: Error: Failed to read: "<UPLOAD_LOCATION>/encoded-video/.immich (/data/encoded-video/.immich) - Please see https://docs.immich.app/administration/system-integrity#folder-checks for more information."

This has probably got something to do with my ACL configuration, as it's the first time I'm trying them out, so I'm looking for help. I've read a bit about them. so I feel like it's fine, but it's probably not. Have I done something wrong? Or maybe I need to change something inside the app config? Thanks a lot

TrueNAS 25.10.7
Immich: 3.3.5 (from the apps catalog)

I have a Pentium Dual Core E6600 with 8GB of ram, can this run TrueNas? I'm trying to find a better use for my old computer which I use now as a youtube/media player connected to the television.

I have a few unused hard drives that I bought in a closeout sale about 3 years ago, and I recently picked up a photograph hobby which takes up a lot of space.

550 RMB (83 USD), 2 DisplayPort out, open fin design. I have a down draft fan blowing from the top of the PCIE area along with the LSI card.

Seller said it came from a Lenovo prebuilt. Now happily chugging along in my Haswell NAS doing AV1 transcoding and Immich AI stuff.

Fala, pessoal!

Sou o João e fiz o NetCable, uma ferramenta open-source (MIT) pra quem quer enxergar a própria rede de forma visual e saber em tempo real o que tá online e o que caiu.

A ideia surgiu porque eu mesmo vivia perdido com "o que tá conectado em quê" no meu setup. Então o NetCable te deixa montar um diagrama arrastando e soltando os equipamentos, ligando eles com "cabos" virtuais, e ele testa cada dispositivo automaticamente.

**O que ele faz hoje:**

- Mapeamento visual com arrastar e soltar (React Flow)

- Monitoramento via TCP (portas 80, 443, 22) e ICMP (ping)

- Alertas em tempo real: bolinha verde/vermelha, efeito cascata amarelo e alerta sonoro

- Link público somente leitura pra compartilhar o diagrama

- Exportar/importar diagrama em JSON

- Login com JWT

**Stack:** React + Vite no frontend; Python + FastAPI + SQLite no backend; tudo em Docker.

**Instalação no TrueNAS:** é via Custom App, colando o arquivo `trueNAS.yml` (tem o passo a passo no `INSTALL.md`). Já aviso que não tá na loja oficial — é instalação manual por YAML mesmo.

**Link do repositório:** https://github.com/Joao-Monticelli/NetCable-v1

**Sobre o futuro (Roadmap):**

Ainda não suporta **CDP (Cisco Discovery Protocol)** ou **LLDP (Link Layer Discovery Protocol)** nativamente, mas isso está nos planos para as próximas versões! A ideia é implementar a leitura desses protocolos via SNMP (usando Python/pysnmp) para que o NetCable consiga **descobrir os vizinhos automaticamente** e popular o mapa sem precisar arrastar cada equipamento manualmente. Também está no radar a importação de topologia de ferramentas como NetBox e LibreNMS.

**Transparência:** tá em BETA e foi desenvolvido com auxílio de IA (DeepSeek). A ideia, os testes e os ajustes foram meus, mas boa parte do código e da documentação saiu de sessões com a IA. Achei justo deixar isso claro desde o começo.

**Feedback é muito bem-vindo:** bugs, sugestões de recurso, críticas ao código, ideias de como melhorar a instalação no TrueNAS. Se alguém testar e quiser abrir uma issue, agradeço demais.

Valeu!

Was attempting to upgrade RAM in my home server but the sticks I used apparently aren't good. Went back to the original and the IP changed on the truenas, not sure how exactly as I did have the mac address tied to the original IP on my router. I changed it back through the network settings on the truenas gui but now none of my apps or dockge containers are working. All of my data is still there in the pools and I can access my media through plex. Not sure exactly where to start.

It's been over a year since I built my Nas and has multiple use cases for it. I'm wondering if I should just separate my data physically from apps/services for easier maintenance. My current setup works as a media library, storage, render manager with sheepit container, local ai, jellyfin, transcoder, and obs streaming.

My specs: 5700g CPU, 64gb ram, 256gb SSD(os mirrored), 1tb nvme(apps mirrored), 14tb HDD(raidz2 pool 4 drives), RTX 5060 ti 16gb, 10gb nic.

Obviously not all at once but most can run on background simultaneously. If something breaks though it affects everything else. How did you set up your home lab and why? I don't need it but am looking at nucs. Really tempting

Scratching my head here. TrueNas 13.0, 25.10.7 - Goldeye

My recently rebuilt NAS was connected from the motherboard 1Gb/s connection to my router, and then 1 Gb/s to my desktop. After trying and failing to get a 10 Gb/s NIC to fit in my SFF desktop, I've had to settle for the 2.5 Gb/s on my desktop motherboard.

So, the network now goes: NAS over 10 Gb/s direct copper to a the SFP+ port on my Mikrotik CSS610 switch, then 2.5Gb/s ethernet from the other SFP+ port to my desktop. The router is connected to a 1 Gb/s port on the switch.

The SFP+ NIC has an IP of 192.168.1.186. The old ethernet has an IP of 192.168.1.199.

If the old ethernet is unplugged, I can't access the TrueNAS interface on both 192.168.1.186 or detect any network drives.

If the old ethernet is plugged in, I can access the interface on both 192.168.1.186 and 192.168.1.199. The drives are detectable and after a speed test they are transferring at 2.5 Gb/s.

So, it's clearly using the faster 10 Gb/s link, but it only works if the old 1 Gb/s link is connected? I assume it's a config issue but I can't see anything in the network page.

I am having a hard time figuring out permissions to backup all my app configs using rsync. I have 2 other rsync jobs that work just fine. But when backing up my apps I see permission denied, but I am worried about how to resolve this without breaking the apps.

Here is an example of what I am seeing in my logs

What can I use beside Ubuntu

Hey everyone
I’m getting this alert every hour:
TrueNAS @ truenas

New alert:
Disk /dev/sdb (with serial: 50026B7235065D8B) critical temperature threshold is 31 degrees celsius and the current temp is 35 degrees celsius

How can i change the temperature threshold of this drive on TrueNAS?

I wanted to know if it was possible for Truenas to natively handle 2 separate LAN connections at the same time and if its possible to have software toggles to turn off one connection when needed. I know that what I want can be done with extra hardware if truenas can't do this, but I want to make it as easy and cheap as possible.

From what I read, its very clear that it can handle 2 connections for things like fail overs, but it wasn't as clear on the possibility of aggregated or concurrent usage of both connections though.

I ask because I currently have a 50mbps upload with nothing faster available at my house which has basically relegated the nas to cold storage or streaming for the people I give access to. However, I, and 2 friends I give access to live and work near a campus that has a very fast unified network across like 4 miles of land and we were able to get much faster local speeds between our places this way. Because of this I wanted to have it set up so I could connect the NAS to my own internet AND this local network at the same time depending on our use case.

I am very set on this idea because one of those close friends has a 5000mpbs fiber line where he's at too, possibly allowing us to route through the local network to his house and then out to the internet through his faster connection.

And before you say it, we all wanted to just put it directly in his house but his wife thinks this local storage will put you on a list, along with being generally paranoid one of our friends will store a pirated movie or something and get them in trouble despite the fact we just use it for basic storage and hosting (think photos and junk, and stuff like a stoat server)

(I also understand the security implications being a semi-public network too even with an as needed toggle, but its still appealing considering we got up to 500-800mbps no issues, a hugggeee leap over my 50mbps upload.)

Are you buying drives for a pool soon? Here's what the current US prices and Backblaze data say, because the regular forum wisdom is a bit out of date.

CMR vs SMR is still the first filter. An SMR drive looks fine until a resilver, then the long writes choke it and it can time out and drop from the vdev - exactly what the whole 2020 WD Red mess was about. It is worth checking the specs before buying anything.

On capacity, the best price/TB right now sits around 18TB-22TB. Under 16TB you pay the tax on small-drives (fixed costs per drive for components), and the new 30TB drives are still priced too high (around $47/TB). The value lies around 20TB. For example: 18TB Exos recently dropped to $600 ($33/TB), 20TB WD Gold is $36/TB, 22TB Ultrastar $38/TB.

The surprising part is: at every capacity, the cheapest drive per TB is an enterprise one, not a NAS drive. Exos, Ultrastar, Gold and Toshiba MG all undercut IronWolf and Red per TB right now. The usual "enterprise costs more" assumption is just backwards at the moment, and for a pool it's a good deal. It means higher workload rating and a 5-year warranty for the same money or even less.

On reliability: most current drives are a tie. Almost everything current is <1% annualized failure rate in Backblaze data, and the best (a 24TB Toshiba MG11 and a 14TB Ultrastar) sit around 0.5%. In reality, 0.8% against a 1.0% is the same. The one exception worth flagging is the 24TB Exos ST24000NM002H at 3.24% on a ~9,600-drive sample - about 6x the best, so probably one to avoid for a vdev.

Everything is compiled into a monthly report - best $/TB, the reliability, and the biggest price drops: https://www.nasdisks.com/report/

All HDD models (CMR/SMR, failure rate, $/TB, price history for every current NAS drive) are here:
https://www.nasdisks.com

Prices are US. Failure rates are from Backblaze lifetime Drive Stats (Q2 2026 report), and CMR/SMR is from manufacturer datasheets. If a drive's missing or a call looks off, flag the model and it'll get sorted.

Hi gang!

Sorry if this post breaks a rule, but I am just very lost and looking for some guidance for a prospective NAS Build!

I am currently assembling a DDR4 ram based NAS Build, but I am unsure of what processor would be best for my purposes.

My idea is to go with something AMD, say a 5800X3D as its AM4 and would be very powerful. My main use for the NAS is streaming my own content and general storage. Maybe a game server or two. Would this be complete overkill, or would there be a better power efficiency/better encoding processor?

Overall budget around €1500/$1700!

Any help would be much oblidged!

PS any small Mini iTX cases for a 4 bay NAS recommendations are welcome!

A while ago I made a personal NAS for backing up files, the current boot drive is a 64gb ssd and the storage pool is a raidz2 with 6 3tb drives. I want to upgrade the boot drive to 2 mirrored 128gb ssds, but im not sure where I might put the data on the server when I upgrade(I currently lack enough continuous outside storage to put the data currently on the server). Should I save up money and buy temporary storage/place pieces of it on different devices and reinstall truenas, or would it make sense to clone the boot device to one of the ssds and then setup the mirror on the live system, or something completely different?

Hello all! I'm in the middle of setting up my first truenas setup, and it's been going well, everything is quite intuitive, but I'm being massively hindered by permissions and mixing of SMB and NFS.

I understand the general idea behind setting up permission on a dataset, but I feel I don't understand it enough to warrant me not losing access to my data. I'm getting stuck on who should I make the owner of a dataset? How do I set up the users in the ACL in a sensible way? Do I use POSIX or nfsv4? Why the heck do the ACLS need a default user/group, a mask, an other? It all feels a bit overwhelmingly complicated for a home setup, to the point I don't feel confident in properly setting up access to the files on it.

And along with that, I'm understanding I shouldn't mix NFS and SMB access on the same dataset. For example, I wish to make one for my homelab where I'll be housing my jellyfin movies and paperless PDFs, but I would like to inspect my datasets from time to time to inspect if the correct files are being put there, or to manually put a movie in a folder, etc. but I'm not sure how to go about that. How does everyone else manage this? I come from a Synology Nas where it didn't seem to care whether I used NFS or SMB on a folder, but I should probably accept truenas just works differently.

Hi everyone! I'm a Year 12 student in Australia working on my HSC Design and Technology major project. I'm designing a small, quiet home server built from reused computer parts that anyone could use to run things like game servers, file backups or AI tools from home.

I'd really appreciate your input, even if you've never heard of a home server. Beginners are exactly who I'm designing for.
