Good Afternoon Everyone,

I'll try and keep this short, as I can be a little verbose. Here is the short version:

1. I ran out of spinning disk storage on my PC and wanted to setup a NAS
2. I wanted to rip all my movies to a Plex Server
3. I don't want to spend a lot of money (lol i know)
4. I found everything I wanted (app wise) on TrueNAS scale.
5. I bartered some older HDs for baked goods.
6. Built the TrueNAS server on some old hardware.
7. I hit a wall when I tried to get ARM (automatic ripping machine) as the app built in to the store doesn't work anymore.
8. I spent some time on their discord server asking questions
9. They suggested just using an Ubuntu server and install ARM using docker.
10. I don't know linux...like at all. I have a Home Assistance box, but that was just follow these steps, and it just works.
11. I already have a lot of hardware running in my closet, and I don't have any other cases in the house that can hold that many HDs AND optical drives lol. So I don't want to just add another case/heat source in there.
12. I was mulling over the idea of just wiping the TrueNAS OS and just use Proxmox for everything. TrueNAS and plex and whatever I might need.

Do you all think this is a good way for a noob like me to go? Or should just buckle down and learn linux lol.

I just upgraded my server from TrueNAS Core to 24.04 - Dragonfish. I picked this so it would keep all my movies in good shape on the server.

However, I noticed that all the apps (plex, sonarr, etc) are massively out of date in Truenas Scale Drargonfish. Should I upgrade the version of Scale on my server? Will it effect all my videos that are on my server? If I should upgrade, what version should I go to?

I’m trying to understand the impact of running a 7200 rpm HDD together with a 5400 rpm HDD in a mirrored (RAID 1) setup. My understanding is that overall performance will be limited by the slower 5400 rpm drive, so any extra performance from the 7200 rpm drive won’t really be realized.

So in this configuration, does the 7200 rpm drive effectively runs at 5400 rpm or whether it continues to spin at 7200 rpm, with the system simply matching performance to the slower drive?

I have my truenas and a separate docker host. On truenas I have a parent dataset and separate children datasets for each docker app. All made in the web UI. Do I need a nfs share for each app data set or can I have a nfs share for the parent?

I apologies if this has been asked over and over, but I am starting to run in circles. Honestly I just need insight for my situation and hardware recommendation.

I am looking to build a personal NAS for a home lab in a 10in rack (deskpi). I do not have room for a full size server rack and I really don't want to buy a prebuilt nas. I was in the process of gathering hardware for the build until I started discovering more information about nas software setups (the more you know, the more you don't know). Originally I had purchased a i5-9500t in a mini itx mother + ram combo. I read how the i5-9500t doesn't support ECC memory, how ECC memory is utilized when using ZFS for raid, and how zfs is superior to traditional raid (not sure if I said that correctly). Now I am in this loop of do I get hardware that supports ECC memory to be able to utilize ZFS?

Couple things:

• I would be using Truenas scale as core is the legacy
• I don't need more that 4 drive bays so itx is perfect. I already 3d printed the hotswap drive caddies and they work.
• strictly for being a nas. I won't be running anything else on this machine.

I just need help on the hardware recommendation. Do I run a more modern i3 that supports ECC? Do I switch to a xenon platform? Do I switch to a ryzen platform? Worst case scenario I build a itx pc for the wifey to game with us and I just buy new parts. The hardware currently gathered is not a total loss. Any insight would be appreciated please and thank you!

Hey folks,

I am about to setup my first Truenas server and have some questions about my desired configuration.

I plan to use 2x special VDEVs in raid1 (WD RED SA500 latest firmware) limited to small file sizes less than 32kb together with a 3xhdd RaidZ1 and a 16GB optane M10 for the L2ARC(no prefetch data)+SLOG with L2ARC by default setup to exclude the VDEV data blocks (I think thats the default behavior with ZFS?). I want to use 4GB of that optane for the SLOG and 12GB for the L2ARC by manually partioning first via CLI. The OS boot drive will be another Optane M10 16GB.

Will the TrueNAS GUI accept that configuration and will it persist across version upgrades or will it flag the deviation from standard middlewared template and fail to work?

PS: This will be a Proxmox VM as I dont plan to use Docker from TrueNAS and prefer rootless Podman for security. So I am guessing it wont require a fast zpool space for containers at all, and hope to cram the 16GB Optane for the OS drive.

Thanks

I get the follwing warning in my TrueNAS Alerts:

Warning

Certificate 'truenas_default' is expiring within 1 days.

2026-07-03 12:00:10 AM (America/Chicago)

The above cert is the IXI provided cert from installation. I run OPNSense and generated a Let's Encrypt local lan certificate using acme, create the CA in TrueNAS, and imported the certificate. My is selected from the https configuration pull-down and works fine and will not expire until: 2045-07-11

Is there a way to update or renew the default certificate to prevent constant warning messages? Can I rename the expiring cert, create a new one, and delete the original? Is it safe to just delete the IXI provided truenas_default certificate?

Are there any CLI command to perform accomplish this with openssl?

Running a Unifi Dream Machine Pro + USW Pro XG 8 Switch. My TrueNAS is a is a UGreen DXP 8800 Plus with dual 10Gbe NIC’s.

On TN, I have both NICs set with static IP’s, let’s say .100 and .101. On the UDMP I also have the set to matching static IP’s. Everything work fine/as expected.

But…in the UDMP interface under clients the 2 clients, TN-1 and TN-2 constantly swap IP’s…sometimes they are both the same, sometimes they are flipped and sometimes correct. When i say constant, I mean literally changing every 1-2 seconds.

Other than that I occasionally get a warning in the UDMP that an IP is used by multiple clients.

On the TN machine this is not observable, no swapping of IP’s on the interfaces, no connection issues for devices pulling files from the NAS, etc.

Anyone know what this is about, I assume some kinda bug in Unifi?

​Hi everyone, ​I am planning a 24/7 home server build for TrueNAS/ZFS storage and containerized services (Plex, Immich, etc.). I've put together a parts list, but I would love to get a sanity check from those with more experience before I buy. ​Planned Build: ​CPU: Intel Core i5-12400 ​Motherboard: Gigabyte B760 Gaming X WIFI6E ​CPU Cooler: 1StPlayer CRYO CY12D ​RAM: 32GB DDR5 (Corsair Vengeance) ​Case: Fractal Design Define 7 XL ​Existing Hardware (already in my possession): ​HBA: LSI 9300-8i (IT Mode) ​Storage: 10x 8TB HDDs ​PSU: 850W High-Quality unit ​Boot: New SSD ​My questions: ​Compatibility/Stability: Does this CPU/Mobo/RAM combo look solid for a 24/7 ZFS build? ​Thermal management: With the Define 7 XL and 10+ drives, are standard case fans sufficient to cool the LSI 9300-8i, or should I add dedicated active cooling for the HBA? ​Future-proofing: I plan to add an NVIDIA GPU later for AI and Transcoding. Do you see any PCIe lane bottlenecks with this board and HBA setup? ​Any feedback or potential "gotchas" would be appreciated!

About 4 months ago I shared a web UI I built to make generating immich-go commands easier for people who aren't super comfortable with the terminal. The response from this community was amazing, and based on your feedback, I’ve just pushed a massive update (v0.2.0).

Here’s what’s new:

• Immich v3 Compatibility: The generator is fully verified against the latest immich-go (v0.32.0) and works perfectly with the new Immich v3 architecture.
• New Sources Supported: Added full support for Apple iCloud exports and Server-to-Server migrations (migrating assets from a second Immich server directly).
• Complete Visual Redesign: I completely overhauled the UI with a softer, premium task-card aesthetic inspired by apps like Linear and Notion. It feels much cleaner.
• Smooth Transitions: Added subtle, lightweight cross-fade animations between wizard steps (respects your OS "reduce motion" settings).
• Under-the-hood Polish: Improved the flag registry and refined how API keys are handled. (As always, keys are never sent anywhere—everything runs locally in your browser).

If you missed it the first time: it's a step-by-step wizard. You enter your server info, pick your photo source, toggle some options, and it builds the exact terminal command for you to copy/paste.

App: https://blickoneblickytwo.github.io/immich-go-desktop/ GitHub: https://github.com/blickoneblickytwo/immich-go-desktop

It's fully open-source. Let me know what you think of the new look and the new import sources!

I had a previous question about expired default certificate. I originally installed my own CA and Let's Encrypt Certificate generated in OPNSense via ACME and both were imported. Upon upgrade to 25.10.4 my CA shows up under certificates as "MIGRATED_CA..."

If I need to add another generated certificate from OPNSense, how does that work now? Importing a new certificate simply asks for a Name, Certificate, and Private Key. If generated in OPNSense using my internal CA that is now shown as MIGRATED_CA will that still work?

Hi TrueNAS Community,

I've seen a mixture of suggestions in previous posts on this sub about ways to do this, it seems the most common ways are Krokeit/Czkawaka and DupeGuru.
These are awesome and what I usually use.

I'd like to automate these so I don't have to interact with the GUI once a fortnight and just use cron.
Has anyone set up a system like this?
Example; hardlink files within "media-folder-1", "media-folder-2, "media-folder-3", etc.

Bonus points: I have several download clients that occasionally download duplicate files. I solve this by using the delete duplicate function in Krokeit.
Example; Use "download-folder-1" as reference, delete all folders in same directory. Use "download-folder-2" as reference, delete all folders in same directory. So on and so on.

Any help is hugely appreciated.
Even if you can link to a thread or post where this has been solved before.

Hi everyone,

I’ve recently decided to upgrade my aging Synology DS716+II to a UGREEN DXP4800 (24GB RAM, 2x 1TB NVMe SSD, 4x 14TB SATA). I tested Unraid first and loved the simplicity, but the user management and security features left me wanting more. TrueNAS Community seems like a better fit on paper, so I’d like to give it a try.

My primary use case is Media hosting (Jellyfin), Download automation (qBittorrent + GlueTun) and *arr stack (Radarr, Sonarr).

I have found several guides but I am still a bit confused. So my question is, what’s the recommended configuration (FS, pool layout, cache, L2ARC, SLOG, etc.) for this setup? As you can guess, I’m aiming for a balance of performance, reliability, and efficiency for media workloads.

Also, any other tips, pitfalls to avoid, or optimizations for TrueNAS in this context?

Thanks in advance for your insights!

I do not know if I fully understand what ZFS errors are or what they mean. Curious if I can get a good explanation on ZFS errors, SMART results and what they mean together and apart from each other. I currently have a drive with 73 ZFS errors as of yesterday morning. As far as it's most recent SMART results, which was from yesterdays schedule test. Those results are pretty good to my understanding. Would this be considered something to not really worry about what so ever yet? I have another drive with 1k ZFS errors and UDMA errors that I was going to see if I could let fully die in the raid as I have yet to experience a drive failure yet. These drives are in a RAIDZ2 so I have redundancy to keep it all spinning and running. I am more worried about corrupt data than I am about a drive just dying outright. Just want to get a better idea of how to interpret this info so I can maintain my systems the best as I can.

Thanks for trying to pull a fast one then 180ing way after I had already migrated.

I currently have a 12TB 2x disk mirror with a potentially failing disk. The failing disk is under warranty and will be replaced, but while I’m waiting for the replacement, I’d like to put a spare 16TB disk into the mirror as its replacement temporarily and then swap the new 12TB disk into place when I receive it.

I know it’s not possible to use a smaller disk into a pool that’s been expanded to a larger capacity, but being that I’ll be mixing a 12TB and 16TB disk, my pool will stay at 12TB. Is this possible?
