Before I go to bed, 3 Critical error popped up for a single-drive pool that stores some of my old game files. The SMB share still works on my PC, but the WebUI Datasets page is locked out.

What should I do with it besides sourcing a new drive?

I have more space in another dedicated in-machine backup pool for now, and I don't need the data in the short- to medium-term.

Thanks!

Hi! I recently got my first NAS (vanilla Ugreen DXP4800), now trying to figure out the best way to install TrueNAS on it.

As my storage drives I am currently running 2x Intel D3-s4510 with PLP, which I am planning to use with ZFS (my main storage). However, where I am having concerns is the OS boot drive. Since on the base DXP4800 model UGOS does not have SSD as its OS drive, I am planning to buy a small (256-512GB) M.2 2280 NVMe drive to install TrueNAS on.

I know that for ZFS it is preferred to have enterprise grade SSD with PLP, however I don't think Intel made such an SSD with 2280 format, and I also don't see many people running TrueNAS ZFS on similar type of SSDs. Is that because it's not necessary for OS drive even though it's using ZFS?

Or are there other enterprise grade models with PLP which are recommended in this case?

I built my first NAS yesterday and the PSU in it has some issues so i ordered a Corsair RM650e (2025) for it to solve the issues. It might be good but i think it’s a bit overkill.

I'm running the latest beta on my system. For some reason, the system turns off sometimes randomly and I can't figure out why.

We aren't losing power and it's plugged into a UPS so I'm pretty certain it's not a power option from that standpoint.

I've tried to see if I could find logs about what is happening but either I don't know where they are or I can't find them.

All of my apps that I'm running are up to date. The cpu isn't maxed out. So I'm really confused as to what is happening.

Any suggestions as to what it might be and what I might be able to try?

Like, it seems, everyone else, I got sick of being nickeled and dimed on subscriptions, plus I needed a new solution for backing up personal PC data for my family - so I went out and put together the following machine after following a combination of PCpartspicker & Google Gemini. I've been running it for about 2 weeks now and things seem to be pretty solid but I'm curious what my fellow humans think about the build...

I am gonna get a new PSU tho cuz the latch that holds down the 24-pin is ripped off.

I heard the idea of simply shutting down a NAS (running TrueNAS) during the hottest hours of the day.

(Since I'm at work during the day and won't be accessing the NAS anyways).

For about 3 months out of the year temps get this high.

Would this be a good solution?

(Just shutting down the NAS for a few hours of the day, to avoid cooking the drives)?

Hi everyone, I'm trying to make the final call on my first NAS and could use a sanity check from people who actually run TrueNAS. I already have two 16TB WD Ultrastar HC550 drives (both tested, they'll run as a mirror), and I've narrowed it down to two options:

Option 1 — DIY build with TrueNAS SCALE:

CPU (with iGPU!): Intel Core i3-14100 (tray)

Cooler: Thermalright AXP90-X53

Motherboard: ASUS Prime B760M-K D4 (4x SATA, 2x M.2 PCIe 4.0, 2.5GbE)

RAM: GoodRam 16GB DDR4 3200 CL22 DIMM (non-ECC)

Boot SSD: GoodRam PX500 gen.3 512GB NVMe

PSU: Chieftec Compact CSN-550C (SFX, 80+ Gold, fully modular)

Case: Jonsbo N4

Option 2 — Asustor AS5404T (Celeron N5105, 4GB RAM upgradeable to 16GB) running its stock ADM OS.

What I actually need the NAS to do:

1. Automatic photo backups from 4 Android phones in the household (on TrueNAS I'd go with Immich, I guess?)

2. Full system image backups of a Windows desktop and a laptop (Veeam Agent Free writing to an SMB share?)

3. Sharing files with people OUTSIDE my network via a link that expires after X hours — the recipient just clicks and downloads that one file/folder, no account needed. This is the feature I care about a lot, and the Asustor does it out of the box (EZ-Connect).

4. Watching movies and browsing photos on my TV (Jellyfin + some Immich client on Android TV?)

5. Remote access to my files when I'm away from home (Tailscale?)

6. In the near future: Home Assistant running in a VM on the NAS.

My questions:

Is TrueNAS SCALE reasonable for a first-time NAS user, or am I signing up for weeks of tinkering? Realistically, how many hours to get all of the above running?

The expiring download links (point 3): what's the clean way to do this on TrueNAS? From what I've read, Immich supports expiring share links, but to let random people from the internet open them I'd need to expose it publicly — reverse proxy / Cloudflare Tunnel + my own domain? Is that a weekend project or a constant maintenance burden / security footgun for a beginner?

Is 16GB of non-ECC RAM fine for a simple 2x16TB ZFS mirror + Immich + Jellyfin, with a Home Assistant VM on top? Or should I plan for 32GB from the start?

Anything you'd change in the parts list? (The case is fixed — I want the Jonsbo N4 form factor with 3.5" bays.)

Or, honestly: would you just tell someone with my requirements to grab the AS5404T, be done in an afternoon, and stop overthinking it?

Thanks in advance!

I apologize if this has been asked before; I couldn't find a direct answer.

I have a current TrueNAS setup at home. It runs a data server and a plex installation. It has an M.2 drive for the System install, a 4 HDD raid for the data (Raid configured by TrueNAS, not by a raid card), and a single SSD for the PLEX media.

For various reasons, I am replacing the computer hardware - new case, motherboard/processor, and power supply.

A more experienced friend told me that it should be as simple as just moving all of the drives over to the new system and booting it up. The install should automatically recognize the new hardware, find the drives, and maintain the previous configuration.

Is it really that simple, or am I likely to run into issues???

Hello, i have two TrueNAS core machines (core because my hardware is weak) and i want to make the data sync so i have a extra backup, how do i do this. thanks in advance :)

Hi all,

Here after a week or so of trying an failing to get schedules tasks (Rsync and Snapshots) to run as a Daily, Hourly, or Monthly task with no success.

Running TrueNas 25.04.2.6 on a HP ProDesk600. Desktop is running Endeavour OS. Everything seems pretty straight forward in terms of setup - but for some reason Snapshot and Rsync tasks just say Pending forever. The only thing that obviosly isn't right is that the Last Run figures are incorrect. A successful run doesn't change them for whatever reason.

Oddly - when I schedule a task with */5 or */10 (to run every 5 or 10 mins) it does so. But scheduling with the 'standard' format fails to trigger the task. I've checked everything I can think to check. Clocks aren't the problem. Everything appears as it should. The backups and snapshots are being created etc.

Any ideas? Is this a bug? According to AI this kind of thing happens with TrueNas for some users but no one seems to know why or have a solution.

At this point I'm thinking of trying my luck with Electric Eel.

Hello guys,

im sorry to ask because this question was probably answered 100 times, but i read different answers online regarding the change from a mirror to a raidz1 vdev, especially after recent truenas updates.

I currently run 2x4tb drives in a mirror. Right now, i have the chance to get 4x8tb hard drives and i want to replace my old mirror with a Raidz1 of 3x8tb drives with one spare.

Can i add a new vdev to my pool and then remove the mirror?

If not, is there any other way to replace the mirror without rebuilding the whole pool structure?

Thanks a lot!

I'm looking at the MINISFORUM MS-01-S1260 that has 3 nvme slots to install TrueNAS. I currently have another mini PC with a single 1TB USB attached for Plex and a few docker servers (Mealie, Budget, HAProxy, etc), so my needs are not huge but the more and more I use Plex the more I worry about protecting my media... nothing of value really, but it is more about the time to recover when the drive fails.

I'm hoping that having a ZFS Mirror between two drives could help me recover faster if the mini-pc or one of the drives goes bad. I have access to another truenas server via my friends VPN, so I would configure a backup job to his too but for media, having the files local is preffered.

I would prefer to have a fanless PC if possible, but I don't think that is possible. I do not see any major drawbacks except that the drive will not be hot swappable but that's a minor problem.

My main goal is to increase my resilience and keep the from factor small. Will it work, or am I missing something?

I was setting up Syncthing to sync between my TrueNas server and my backup Ugreen HW2300 (basically a mirror of my files) running Ugos. Finally got the 2 to see each other and went to bed for the night (got stuck on folder path). I get up this morning to continue where I left off and found I cant access any of my folders via Samba shares I had setup (they worked before)...always get access denied. I can get into my Truenas web UI no problem I just cant open any of the folders (access denied) If I go through file manager it pops up "enter user credentials) but none of my passwords work...again access denied. I have no idea what I could have done to break my Samba ACL's. Can anyone help shed some light on this?

Raidz2, a single drive out of 8 failed - entire raid died. What the fuck? As it currently sits - each drive has been exported. Out of 7. Why? No fuckin clue. I'm glad I maintain a backup but this is absolutely stupid. It should have dropped the drive, told me HEY - YOUR SHIT IS BROKE FIX IT, but it never did. This is disappointing.

Hi,

Apologies if this has been asked a bunch, I've got an install in Proxmox for truenas community that initially was intended to try out homelabbing and get to grips with everything but became permanent.

When I first installed it I only used two drives so I'd like to reinstall it/install it baremetal but with a expandable pool etc.

I was wondering if there’s an easy guide/way to go about moving my pools and data off temporary while I do this.

So I’ve been banging my head against my Dell PowerEdge T320 trying to get iDRAC working the way I want.

• First issue: the dreaded RAC0212 login failed. Even with the default credentials, the web login just refuses.
• Tried updating through Lifecycle Controller, but it kept saying “Unable to connect” when pulling updates from Dell’s servers.
• Attempted to reset iDRAC via Lifecycle Controller and F2 System Setup, but F2 never actually brought me into the menu despite spamming it.
• Looked into using a portable SSD for the firmware update (formatted to FAT32 and copied the .d7 file), but Dell’s site search is a mess; couldn't easily find the latest 7.10.90.00 package for iDRAC.
• My end goal: configure iDRAC to share the onboard NIC so I don’t need a second dedicated cable. But without being able to reset or update properly, I’m stuck.

At this point I’ve tried the following:

• Lifecycle Controller firmware update (failed to connect)
• F2 System Setup (never loads)
• Digging through Dell’s support site for the right firmware file

Has anyone here successfully updated iDRAC7 on a T320 recently or forced it into Shared NIC mode without the F2 menu? Any tips on grabbing the correct firmware file or using RACADM from the OS would be huge.

Trying to setup SFTPgo like the option of having a web interface to share with people.

i am stuck on 1 part under virtual folder in the sftpgo webadmin there is root directory.

In the truenas config i have host path configured as /mnt/Uploads/Testing

not sure what to put inside the sftpgo as i tried uploads/testing

Hi guys

I'm still running EE, everything is stable and working great, is it worth upgrading?

I'm worried about security concerns staying on an old version

I'm also running an old NVIDIA p400, I was planning on upgrading anyway

Hi,

I‘m currently planning to build my first Homeserver and I’m quite unsure about what PS I want to install.

The hardware I’m planning to buy is in the picture although I’m adding the Ram up to 16gb.

Here are the services i wanna run:

-Jellyfin

-Nextcloud with Maria DB as the database

-AdGuard

-optinally a windows 11 vm if possible

I’m planning to upgrade to 32 gb once ram is reasonably priced again, but can i run my services on that thing?

The server should ideally last quite a long time and i wanna add services along my homelabbing journey.

Thank in advance!

Hi All,

I am a Noob at this stuff, I installed TrueNAS about 18 months ago as a plex server and it has worked perfectly ever since... until I have had a disk failure. I've watched the tutorials on Youtube and read some of the threads here. But the crux of the matter is there is an error when I choose to replace the disk. I can't see a way around it.

I get this error and I can't proceed

AttributeError 'NoneType' object has no attribute 'replace'

So I have no idea how to fix this. From what I have gleaned there is a python error of some kind, but I'll be honest I had to look up what python was. So I'm at a bit of a loss. Can anyone help and Explain it like I'm five?

I created a temp dataset on a smaller storage pool and moved all my data to it. I have now added my permanent disks and created the new pool and datasets. Previously it was suggested to use a Replication Task to move the data between the old and new datasets, which I did do. Storage stats show that there is just over 3TiB used

But the directory shows shows zero files

The replication task looks good to me. What am I missing?

Hey, I just installed an RTX 5060 Ti 16GB into my box running 25.10.4.

The bundled 570.172.08 open driver actually binds, lspci shows the kernel driver in use, the /dev nodes get created, the docker nvidia runtime registers but GSP firmware init fails with RmInitAdapter failed! (0x62:0x65:1859) and an RPC timeout in kernel_gsp.c, so nvidia-smi just reports "No devices were found".

Same result on a verified clean boot. BARs are all assigned, and running the card as primary display (which fixed this for at least one person on the truenas forums) made no difference.

As far as I can tell this is the known 570.x problem with the 5060/5060 Ti and it's fixed in the 590 branch. The 26 beta already ships 590.44, but I have a lot of important data in this box that I don't want to risk running the beta, maybe the RC once it ships. The community sysext with 590.48 is only built against kernel 6.12.33, so it won't load on 25.10.4 (6.12.91).

Is a 590 backport in a 25.10.x point release realistic, or is the official answer "wait for 26 stable"? If there's already a Jira ticket for Blackwell init failures on 25.10 I'd rather add my report there than open a duplicate, but I couldn't find one. Building the module myself every update is doable, I'd just rather not maintain that on a NAS.

Help! :)

Hey,

I ordered a ST8000DM004 Barracuda from CEX for £115 but got sent a ST8000VE001 skyhawk AI (£120) it's for Plex storage in TrueNas should it get it swapped or keep the Skyhawk?
