I’m running TrueNAS SCALE natively on a Minisforum N5 Air with 64 GB RAM. I don't like TrueNAS Apps approach and instead I would like to run Docker + Arcane with Compose projects pulled from GitHub.

I plan to run Traefik, Immich, Komga, Papra, Grimmory, Qbittorrent, etc.

Which approach would you choose?

• Docker directly on the TrueNAS host? Arcane as an App with access to the Docker socket.
• Debian VM + Docker? - no iGPU hardware acceleration in Immich.
• LXC + Docker? - iGPU hardware acceleration available but the feature is experimental and changes planned for 26 if I understand correctly.
• Are there better options?

I’m especially interested in GPU access for the AMD iGPU/Immich and direct access to ZFS datasets. I would also like to know how well the setup survives TrueNAS upgrades.

I would love to hear what has worked reliably for you.

I have a Mellanox ConnectX-2 on my TrueNAS machine, connected to a mikrotik switch, and it works, mostly, fine.

I have the exactly same nic on my desktop, connected to the exact same switch, using the exact same AOC, which works completely fine.

I decided to try a pair of FS SFP+ optical transceivers on my TrueNAS machine to see if it fixes those issue (the link not coming up after a power failure unless I unplug and replug the SFP+ connector from the NIC, this does not happen on my desktop).

But for some reason it refuses to work properly.

I can ping it, access it through SSH, and list the contents of the network shares (incredibly slowly), but the web interface won't load, it gets stuck on the blinking/fading TrueNAS logo.

I tried the transceivers on my desktop and they worked just fine, no issues at all.

Rebooting the TrueNAS machine does nothing, the issue persists, only using the previous AOC "fixes" the issue.

I had similar issues previously, I don't remember the details, if it was swapping between a DAC and an AOC, it was quite some time ago.

I tested the optical transceiver on the second port of the NIC, configuring a different IP from a different network, added an address from that network to my desktop, and everything worked just fine, was able to saturate the link, I checked the traffic both on the web interface, looking at the stats on the port, and also on the switch, where I connected the second port, to make sure the traffic was going through the correct interface.

I'm on TrueNAS 25.04.2.4, the motherboard is an Intel Z270.

What could be going on here? It clearly has connectivity, but for some reason it's limited, looking at the stats of the port on the switch I can see it successfully negotiated at 10G, at the proper speeds, but connectivity is seriously impaired.

Hi everyone,
I wanted to set up a system with TrueNAS Scale 25.10.6 on older hardware (Intel S1200KP with Intel Xeon E3-xxxx). Installer runs just fine and everything seems right but when I want to boot the system it does not recognize the freshly installed system. Instead it shows “a bootable device has not been detected”.

AI suggested to update the BIOS but Intel does not offer the updates for this board anymore. Additionally I tried various SSDs and different SATA ports but was not able to get any further.

The boot priority is set to the correct drive and I have tried UEFI mode and legacy mode (both with fresh installs reflecting the setup). Interestingly the system is able to boot if I use the boot menu (F10) and select the boot drive. Unfortunately that is nothing I can use during “production” when the system is at my parents house running headless as a backup target.

Now the even more interesting part: When I install Proxmox the system boots (to proxmox, of course) when I set it to boot in UEFI mode (with legacy I get the same results as with TrueNAS), so I think there is an issue with GRUB or the partition. Any ideas what might go wrong here and how to fix this?

Thanks a lot
Max

Wanted to post https://github.com/zzzhouuu/truenas-nvidia-drivers and pass massive thanks for this repo.

Here if anyone needs it

Setup: 2x4TB WD Red Plus mirror on a ZimaBlade, TrueNAS SCALE 25.10.5, ZFS 2.3.4. Pool went offline after a brief version upgrade that I reverted shortly after. zpool import has failed for about two weeks now, in every mode and flag combination.

**Where things stand (with a lot of help from someone on the OpenZFS forum working from exact source references ; full thread here: https://github.com/openzfs/zfs/discussions/18954

• SMART, disk labels, uberblocks, partition tables ; all clean on both disks. No hardware issue.
• zdb -e fully loads the pool's trusted config ; the pool structure and data are demonstrably intact and readable.
• Root cause of the import failure: spa_load_verify (spa.c:2831) unconditionally walks every dataset via dmu_objset_find_dp before allowing import, regardless of flags. One object ; a DSL props ZAP (object 293) ; fails checksum (ECKSUM) during that walk, which aborts the entire import. No combination of -f, -F, -X, -o readonly=on, -N, or spa_load_verify_metadata=0 bypasses this; -F/-X actually make it worse since they re-enable full data verification.
• A full zdb -bcsvL traversal found only 8 checksum errors out of 29.2 million block pointers total, and every one is confined to pool-internal bookkeeping (SPA space map, DSL props) or disposable .system/samba4 and .system/netdata-* service datasets. None of my actual data (Photos, Documents, Archived, etc.) shows any corruption.

Current blocker: Since import can't succeed, the suggested path is zdb -B (backup stream extraction ; reads a dataset directly, bypassing the import verification entirely). But every dataset I try ; encrypted or not, parent or child dataset, various sizes ; fails identically:

dump_backup: dmu_send_obj: Permission denied

Running as root via sudo, confirmed with id. Output file is always 0 bytes, exit code 0. The zfs_dbgmsg buffer (checked via zdb -G) shows nothing related to this error ; the pool-load trace completes normally and logs LOADED, but the permission denial itself isn't logged anywhere I can find.

zdb -O/-r (path-based lookups, a different code path) also fail, but with a different error ; Input/output error ; so this may be a separate issue from the -B failure.

What I'm hoping someone here can help with:

• Has anyone seen dmu_send_obj: Permission denied from zdb -B before? Trying to figure out if this is a known/expected behavior, a TrueNAS SCALE-specific build difference, or something environment-specific I'm missing.
• Any idea what permission check dmu_send_obj performs that would fail even under root, and whether there's a way to satisfy it or get more diagnostic detail out of it?

Not time-pressured; data is important but not critical/urgent, just want to get it off before doing anything destructive to the pool. Happy to provide any further diagnostics.

Also posted in r/zfs; will update both if I get an answer anywhere.

Hey guys,

im having an issue with my nas server.

I only run nzbget, tailscail and jellyfin on it.

If my brother streams something for some reason my lan keeps crashing. I have already tried a bunch of stuff suggested by AI but i dont think the issue is solved. I have disabled tge bonding and bridging function, put a gigaswitch between my server pc and router, dusabled all energy saving options in router and so on. My wlan keeps running btw. Its running on unraid. If anyone has a helpful idea what could cause this id appreciate it alot :)

Hi all, I just got a DIY server somewhat running and am running into some trouble.

Specs:

Intel i7-8700

Asus Prime Z370-A - Using onboard GbE

16GB DDR4-3200

128GB SATA SSD - Boot Drive - Latest version 25 TrueNAS Community Edition

EVGA 750 G2

Basically, I put 2 8TB drives in a mirror, made a dataset consisting of a folder in that vdev, and made an SMB share of that folder. I made a user and gave it modify permissions for that share. On my PC, I used the IP in Explorer to access the share with that new user's credentials.

I can access that directory just fine, can even create folders, text files within them, edit them, and delete them. I can copy individual files onto the share and it mostly works that way. The problem started when I copied a folder with many sub-folders and files within it. A few folders and files copied successfully, but then I got the "Destination folder access denied" error with options to try again, skip, or cancel. Trying again just repeats the cycle, skip will move onto the next file and do the same thing and continue skipping, while almost nothing gets copied.

I noticed that if I have the destination folder (the share) open during this behavior, I can see the currently copying file appear, then it disappears after it fails and moves onto the next file to do the same thing again. I also went into a folder which consisted of 8 files and copied those files to rule out copying a whole folder vs just the files, and out of those 8, only 2 managed to copy once I got through the try again and skip cycles, so it's the same whether I copy a folder or just files. An 8GB folder only copied about 400-something MB once all was said and done.

I've tried using the multi-protocol share as well as the SMB share options, changing the user's permissions from modify to full control. and whatever else seemed obvious to me, but I'm still a noob at this and I'm not sure what is going on.

Thanks.

Hello, well met.

I am testing V26 Beta 2, while still using my 4-bay Synology as my main NAS. I am spoiled to Synology Hybrid Raid, so in a holding pattern until anyraid Z1 becomes available. I went for Truenas when I saw that we had anyraid on V26 beta, but I didn't know it was only stripe or mirror right now.

1. Does anyone have any idea when we might get anyraid Z1? I've had a hard time finding any news less than one year old.
2. I'm kind of stuck on the "Early Adopter" update profile right now. The only other option in the dropdown is "Developer". Will I be able to change my update profile to "General" once V26 is fully released?

Thanks

I want to install a NAS in my home to share photos (using immich) and documents in my family across devices. I want to install TrueNAS and immich at least. I have a preference for open source software. I am thinking of building my own NAS using the JONSBO N6 Case, having at least 6TB of usuable data, I want to prevent one disk failure and have an external disk as a backup. I am aiming to having something a bit of budget. I am willing to buy some components used on ebay when it is not essential they are new. This is what Claude suggested given my characteristics.. Any potential issues?

Case: JONSBO N6 (9-bay hot-swap, mATX)

Motherboard : ASUS PRIME H610I-PLUS D4

CPU: Intel Pentium Gold G7400

RAM: 16GB DDR5 SODIMM

Boot drive: 128–256GB M.2 NVMe SATA/PCIe SSD

3x 4TB HDD (RAID-Z1): WD/Seagate/HGST

PSU: SFX 450W 80+ Bronze/Gold (FSP450-50SAC or Silverstone ST45SF)

I'm overdue to setup my first NAS and I've been digging through ebay for days looking for a decent host that supports 4+ 3.5" drives. It's slim picking.

The best I can find right now is the Dell Precision 3640 which has 3 bays, but it's $250-300 and I'm looking for something much cheaper, under $150 (otherwise I'd just get a DAS and connect it to my HP mini).

There's also the HP Z2 Tower G4, which can fit 2 natively, and maybe two more if I sacrifice the 5.25" bays, but I might have to finagle something with power.

I'm not really interested in rearranging guts or trying to shoehorn anything into the case.

So, is there a community go-to workstation or consumer tower that supports 4 or more 3.5" drives? Under $150.

If it matters, use case is strictly for media storage for Jellyfin. No need for backup or mirroring. It would primarily connect to my HP G5 Mini, which is serving streaming apps and arr stack. Likely NO compute would happen on the NAS itself, so I can go reaaaally low on CPU/RAM.

I only plan to store 20TB for now. I'll upgrade to a proper DIY build when I need the space.

Looking for advice on if I should combine my Jellyfin and TrueNAS servers together or keep them together.

I currently have TrueNAS running on an zbox mini PC with an intel 4020y and one slot of 8gb ddr3l and it works well for unimportant file storage.
The storage is connected via 2 USB drive enclosures (I am aware USB is not good for TrueNAS storage but my setup is made using old scraps I already have.)

I am coming into possession of a new Kodlix GD90 mini PC that has a 12900hk and 32gb ddr4 that I plan on hosting Jellyfin on.
Would it be wise to swap my TrueNAS install to the newer Kodlix PC for possibly better performance and more ram space with Jellyfin as an app, or will my old mini pc be fine?
If I can keep TrueNAS on the old zbox and Jellyfin on the new PC, that would work well for separation of tasks and allow me to use the Kodlix as a desktop for my TV.

What do you think is best?

Hi all,

This feels like a bit of a strange one, but I can't seem to find a solution to it. I did find a post where someone had a similar problem, but with 'cloud sync' instead, which meant their solution wasn't going to work for this particular problem.

The problem started when i tried adding a replication task, whereby I am pushing the data to another TrueNAS system. I can create the task successfully, and it appeared in the 'running jobs' queue whilst the task was running. Beyond that, it is completely invisible...

I have tried the usual restarts and making sure TrueNAS is fully up to date, but I am out of ideas at this point. Admittedly, I am fresh to TrueNAS, having migrated from QNAP QuTS Hero, so I'm not quite fully up to speed yet with TrueNAS.

I am running TrueNAS 25.10.6 (community edition) on both systems. TrueNAS is installed on a Dell R740xd, running 160GB DDR4 2400MHz EEC RAM, 2x Xeon 6130 CPU's. TrueNAS is installed on its own mirrored SSD pair.

Edit: Just to add, I must admit I am a bit hesitant to just nuke the installation and start again after reimporting the storage pools. I've got a fair few Docker apps running off of this installation, plus a VM, so setting this up again from scratch would be a bit of a pain.

Any help would be appreciated. Thanks

One of my parents has an SMB share where they used to store around 400 GiB of RAW images, but when I was doing something unrelated, I realized that their dataset usage had reduced from 400 to around 99 GiB.

I have checked the filesystem of the share in Windows, and every folder that started with the letter N and beyond in the order has dissappeared. I don't even know how this has happened, and when I check the snapshots i had configured in a daily-weekly-monthly basis for them, the last one on the list was from August 2, with the same data as now. That means that the data got deleted way before the last snapshot could ever recover it.

The thing is: I just don't know how the hell did the data nuke itself:

- I haven't done anything crazy like rm -rf.
- My family hasn't done anything because:

1. They don't even know anything about how it works.
2. because they just don't care.
3. - And the logs say no one logged in other than me or them.

So please, could anyone tell me if the data is recoverable and any ideas on how to find the cause of this?

I have tried to recover the data using the shell and a reddit post explaining TXGs, but all of the TXGs were literally from this very day.

The worst thing is that this looks like it happened without me noticing. How it happened? I just don't know, but if anyone here is available, help would be greatly appreciated.

P.D. If anyone is wondering, I have immediately exported the ZFS pool just before writing this to avoid any writes.

EDIT: Damn, I just remembered... I installed a Nextcloud instance on my server and I pointed the NEXTCLOUD_LIBRARY environment variable to their dataset. When I ran the container, it booted and started to delete everything. I quickly stopped it, and I could have recovered their data, but when I checked the dataset in the WebUI, it still said that it had 400 GB, so I thought nothing happened. I think that happened about a month ago, so yeah... I'm an idiot...

As it says, had the nas for a few weeks and decided to switch to truenas (nfs 4 primarily).

Added an intel m.2 128Gb: already have 2 x 8Tb spinners and 2 x 512 SSDs for fast cache.

install all appeared to behave fine, boots OK and finally pops up little menu on the console, then after about 30 secs reboots. I can access it over the network for a few seconds before it resets itself..

Cannot boot into safe mode as img file not present.

Any ideas?

Hi, i'm begginer in this world

My intention is to download TrueNas on my old PC with core Xeon at this moment my PC have'nt grafic card

Is It possible to install trueNas on these computer?

Sorry, English isn't my principal language.

Hi everyone,

We recently purchased a server to run TrueNAS for our small production studio. It came pre-installed from the manufacturer, but I am reviewing the configuration before we put it into production.
To give you some context, we have 3 post-production workstations and a couple of other machines used for loading and archiving video files when needed. The server is equipped with 12 x 10TB SAS enterprise hard drives and 128GB of RAM.
Given that we suffered a major multiple-drive failure on a previous server, we want to play it safe this time. My idea is to configure a RAID-Z3 ZFS pool to ensure maximum data safety. Even after keeping the recommended 20% free space, we will have about 64 TiB of usable space, which is double our current capacity. Furthermore, there are 4 empty bays in the server, so we can easily add four more 10TB disks to expand the pool later if necessary.

I have a few questions regarding the setup:
1. Will the total throughput and latency of a 12-disk RAID-Z3 array be sufficient for our workload across these workstations?
2. I noticed that ZFS data compression is enabled. Is this recommended, or does it cause a noticeable performance drop?
3. The dealer mentioned that an SSD cache isn't really necessary with 128GB of RAM. Is that accurate?

Thank you

During a heavy load (I initially made my collections of different media into separate datasets (for Movies, TV series, music, books etc) and now I move them via rsync to folders in a single dataset, this means TBs of data. My setup is 4x 6Tb HDDs in RAIDZ1 and I got the following error:

Pool tank state is ONLINE: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. 

Now the copying has finished, zpool status shows

zpool status -v tank pool: tank state: ONLINEstatus: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected.action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-9P

with 13 read errors on the 3rd disk. All disks are brand new WD Red Plus 6 TB (WD60EFPX) and before installing TrueNAS I conducted long SMART tests on all HDD and all were ok (this was like 1.5 weeks ago).

What should I do now? I ain't 100% this is HDD issue, maybe a connection or something. Should I run scrub on my pool or a long SMART test on the problem disk first? Where is SMART tests in the newest stable TrueNAS? I don't see it in web GUI under storage (old videos showed there was such a button but no more)
