homelab

As the title says I’m curious what quality people choose. I chose Ultra-HD and am a little stunned when I look at the file sizes for some movies at 100GB.

Another question is how can I change the quality and will Radarr remove the existing download and then get a smaller one?

If it helps I have a GPU capable of hardware transcoding.

When combined with today’s other vulnerabilities, CVE-2025-1974 means that anything on the Pod network has a good chance of taking over your Kubernetes cluster, with no credentials or administrative access required.

I got a server recently and now I need storage and I’m a little upset seeing the prices of HDDs.

My aim is for 4x10TB to run on RAID 5.

I saw other people linking serverpartdeals and they do ship to the uk but the shipping is insane particularly as I want to buy them one at a time to spread the cost.

So what would you guys suggest? New ones are hella expensive, but I can’t seem to find any decent places selling manufacturer recertified ones.

I've recently gotten into homelabs I've got a Mini-PC running Immich and Home-Assistant

I'd like to setup a NAS for the Immich server to save media to.

I'm very new to the game and only recently started looking into this.

One requirement for me is it must be Open-Source. TrueNAS?

What hardware would you recommend? Having 2TB for now with the ability to expand it would be great, a small size would also be ideal.

Hey community! Do you use any database or anything to manage your environments? I started a relational Notion database a while back but never dug in. Objects types for things like hardware, software, deployments, technologies, and tie-ins to my other LifeOs databases. (e.g., the inkbird aquarium thermostat in Smart Life/Tuya via Home Assistant is linked to my aquarium database as a gear object.)

I'm rebuilding half my lab right now and thought it might be worth seeing if there's a better method before returning to my half-assed system.

(I pay for Notion - I also failed at making my super complex Obsidian implementation work across my devices and platforms. I'm in the market for a replacement for that whole universe, so if this thread turns into a moratorium on Notion, I get it. Still, I'm open to discussion, so snark is unnecessary.)

Hi - I'm rebuilding my homelab and want to give docker compose another try. It looks like Watchtower is years out of date now. I see two forks that look more promising per https://techgaun.github.io/active-forks/index.html#https://github.com/containrrr/watchtower

These two: https://github.com/beatkind/watchtower https://github.com/nicholas-fedor/watchtower

The former seems to have more activity. What are you all using?

I am upgrading my drives and have created a new pool. The original pool had a drive fail, but it has since been replaced. Each drive CKSUM value is at 4.04k and pool had two files with permanent errors. I deleted those, but it now shows this:

errors: Permanent errors have been detected in the following files:

        zfsa:<0x8220>
        zfsa:<0x8056>

When I try to create a snapshot and send it to the new pool. After a few terabytes, it fails with this error warning: cannot send 'zfsa@zpool_transfer': insufficient replicas.

CKSUM was always at zero until the first drive failed. The data is not important and I don't care about whatever is corrupt, I just want to get the data to the new pool.

Edit: Forgot to mention, I have scrubbed the pool many times.

Another edit: I've also tried using zpool clear as well. Despite the high checksum errors I've had no issues outside the two now deleted files. The pool is used for a media server which has been working perfectly.

After I scrub the checksum errors go to zero, but they start climbing when I run the send/receive.

Edit:

Finally remembered to come edit this post with the solution I got from the Practical ZFS forums. Thanks to Jim Salter over there for the solution!

You can bypass the checks by settings a ZFS module parameter. A way to do this temporarily is with echo 1 > /sys/module/zfs/parameters/zfs_send_corrupt_data, which will last until you reboot. After doing this, sending the data, and a scrub, everything was fine!

Title. If none - why?

I was looking to upgrade my storage and was recommended to go with used SAS drives and an LSI SAS controller. I purchased an LSI 9211-8i HBA, 8TB Seagate Exos drives, and these cables. The drives are not spinning up at all when connected to the power supply. Are these cables not the right choice for this?

Edit: I have confirmed that a regular SATA drive works if connected with an SFF-8087 to Sata cable. Either I've somehow received 10 dead drives or I'm not powering them right.

Edit 2: I'm guessing its related to this: https://forums.unraid.net/topic/84038-so-your-new-sas-or-sata-drive-wont-start-spin-up/

What an irritating issue.

So my options seem to be:

• Tape mod the SATA power adapter or drives to prevent pin 3 from disabling the drive - cheap but tedious
• Use a molex adapter to power the drives - less cheap, I'd need new PSU and SAS cables
• Upgrade my PSU to one that supports SATA 3.3 - I'll probably do this. I just bought a new PSU for the purpose of powering these drives, so I can still return it.

Hi all! I had posted a similar post in selfhosted, but it was deleted because it was only hardware-related. Therefore a new attempt here in the correct sub.

I want to reorganize my home server landscape a bit. A Proxmox server is to receive an LXC, with ollama and open webui. This is to be used for other containers that categorize via AI (paperless-ai, hoarder, actualbudget-ai, maybe home assistant speech) and also for one or the other chat. Speed is not so important to me, focus is on low idle and models up to 100 GB. It's ok to wait several minutes for answers. I don't want a GPU.

(Currently I successfully use models up to 32b on a Lenovo M920x with i7-8700 and 64 GB RAM. These models are supposed to run faster or slow up to 100b)

I want to spend 2000, if necessary 3000€ (mainboard, CPU, RAM).

My research showed that the bottleneck is always the memory bandwidth of the CPU. I would take 128GB RAM and want to use all channels.

Current variants: Intel i9-10940X, 14C/28T, 3.30-4.80GHz Quad Channel DDR4 93.9GB/s

Intel i9-14900K, 8C+16c/32T, 3.20-6.00GHz Dual Channel, DDR5, 89.6GB/s

Intel Core Ultra 9 285K, 8C+16c/24T, 3.70-5.70GHz Dual Channel, DDR5, 89.6GB/s (CU-DIMM: 102.4GB/s)

Intel Xeon Silver 4510, 12C/24T, 2.40-4.10GHz 8-Channel, DDR5, 281.6GB/s (means you need 8 sticks!)

Intel Ryzen 9 9950X, 16C/32T, 4.30-5.70GHz Dual Channel, DDR5, 89.6GB/s

These would all be in the €1500-2500 range.

Do you have any concrete experience? At the moment I prefer the Ultra 9, it's the latest platform and expandable. I prefer Intel because it is more energy efficient in idle mode.

The Xeons have the disadvantage that they have many channels, which then have to be filled with memory sticks to achieve the full rate =more energy, more cost).

when will amd release Siena CPU refresh?

I like 80W TDP epyc, but its been awhile since released.

I have a T630 that has started powering off after a random amount of time, usually less than 12 hours. When it powers off the backlight of the front panel LCD goes off as do all lights on the case, and iDRAC also doesn't work. So it looks like there's a problem in the power. Dell support seem to have run out of ideas, presumably because they don't want to suggest that I replace parts and they know I'm not going to pay Dell support.

I suspect it could be a faulty Power Backplane board J14R7 0J14R7, how would I test for that?

Hello there,

I’ve been running a little army of raspberry pi and libre computer lepotato for many years now.

Sometime died of overheating, one died because the microsd card failed so hard that some kind of electrical shock took off the whole pi.

I’m looking at this trend: replace that with a single or a 2 node cluster of mini pc.

The point is I still want to consume as less electricity as possible. So low TDP CPUs <10 to 15W is my most important criteria, then 2 disk bays (don’t care about the form factor or connector).

Reading buyers comments on Amazon indicates that cheap Chinese mini pc have their ssd dying quickly, or their motherboard, or their power supply, sometimes in months, not even a year.

Would you please recommend a low power mini pc please ? It may be Chinese but from a reputable brand (which I fail to determine).

I'm looking to upgrade some of my internal systems to 10 gigabit, and seeing some patchy/conflicting/outdated info. Does anyone have any experience with local fiber? This would be entirely isolated to within my LAN, to enable faster access to my fileserver.

Current existing hardware:

• MikroTik CSS326-24G-2S+RM, featuring 2 SFP+ ports capable of 10GbE
• File server with a consumer-grade desktop PC motherboard. I have multiple options for this one going forward, but all will have at least 1 open PCIe x4+ slot
• This file server already has an LSI SAS x8 card connected to an external DAS
• Additional consumer-grade desktop PC, also featuring an open PCIe x4 slot.
• Physical access to run a fiber cable through the ceiling/walls

My primary goal is to have these connected as fast as possible to each other, while also allowing access to the rest of the LAN. I'm reluctant to use Cat6a (which is what these are currently using) due to reports of excessive heat and instability from the SFP+ modules.

As such, I'm willing to run some fiber cables. Here is my current plan, mostly sourced from FS:

• 2x Supermicro AOC-STGN-i2S / AOC-STGN-i1S (sourced from eBay)
• 2x Intel E10GSFPSR Compatible 10GBASE-SR SFP+ 850nm 300m DOM Duplex LC/UPC MMF Optical Transceiver Module (FS P/N: SFP-10GSR-85 for the NIC side)
• 2x Ubiquiti UF-MM-10G Compatible 10GBASE-SR SFP+ 850nm 300m DOM Duplex LC/UPC MMF Optical Transceiver Module (FS P/N: SFP-10GSR-85, for the switch side)
• 2x 15m (49ft) Fiber Patch Cable, LC UPC to LC UPC, Duplex, 2 Fibers, Multimode (OM4), Riser (OFNR), 2.0mm, Tight-Buffered, Aqua (FS P/N: OM4LCDX)

I know the cards are x8, but it seems that's only needed to max out both ports. I will only be using one port on each card.

Are fiber keystone jacks/couplers (FS P/N: KJ-OM4LCDX) a bad idea?

Am I missing something completely? Are these even compatible with each other? I chose Ubiquti for the switch SFP+ since Mikrotik doesn't vendor-lock, AFAICT.

I'm currently planning to build a low power nas for my upcoming minirack (10").

It's going to store daily proxmox vm disk snapshots, some image files and some backups from my laptop, all via NFS. Plus some more in the future, but generally, it's going to idle 95% of the day. Not decided on the OS yet, probably TrueNAS Core or OMV.

I already have an Olmaster 5,25" JBOD in which I'll put 3 x 2,5" 2TB SSD via SATA. The JBOD needs a single Molex connector for powering all SSDs. So I need at least 3 SATA + Boot.

Some recherche led me to this post and I tend towards a similar build with a J4105-ITX (cheaper, probably little less power consumption, enough CPU ofr NAS).

These officially are limited to 8GB RAM but seem to work fine with more if you don't update your BIOS which is not optimal but acceptable if everything else works fine. I'd like 16G for efficient ZFS but I guess even 8 are fine if it's not doing much else (2GB base + almost 1 for each TB storage + OS), just don't tell TrueNAS forum users.

While I don't plan 10G ethernet now, the PCIe slot should leave that possibility open.

I read good things about PicoPSUs, but that depends on which case I get as they usually already got some PSU.

The case question remains open - I tend to get something like the LC-1350MI-V2 as it's cheap, contains a 72W PSU and fits into the 10" rack nicely. In that case, I would need to go out of the case with the SATA cables and rack the JBOD on it's own - which is fine since there's pritable files for exactly that. Other possibility would be to get a case with bays for the 2,5" (seems unnecessary since I already have the JBOD and don't want to add more requirements to the PSU) or get a case with a 5,25" bay (rare in cases this size).

I'm mostly asking for advice regarding the case/PSU thing but nothing is set in stone other than the SSD/JBOD combo. I'd like to keep the rest < 150€ and prefer used hardware, at least for the case. I'd be glad for your thoughts and ideas!

I want to establish a second LAN at home. It's supposed to host different services on different infrastructure (vms, k8s, docker) and mostly serving as a lab.

I want to separate this from the default ISP router LAN (192.68.x.0/24).

I have a machine with 2 NIC (eno1 plugged in at ISP router and eno2), both with corresponding bridges and proxmox. I already set up the eno2 bridge with a 10.x.x.x IP and installed a opnsense vm that has eno1 as the WAN interface in the 192 network and eno2 as the LAN interface as 10. network with dhcp server.

I connected a laptop (no wifi) to eno2, got a dhcp lease and can connect the opnsense interface, machines in the 192 network and the internet, same for a vm on the eno2 bridge, so that part is working. There's a pihole in the 192 network that I successfuly set as the dns server in opnsense.

Here's what I am trying to achieve and where I'm not sure about how to properly do it:

• Block access from the 10 network to 192 network except for specific devices - I guess that's simply firewall rules
• Make services (by port) in the 10 network accessible to the internet. I currently have a reverse proxy vm in the 192 network which got 80 and 443 forwarded by the ISP router. Do I need to add a second nic to the vm or can I route some services through the firewall? I want to firewall that vm down so it can't open outgoing connections except for specific ports on specific hosts.
• Make devices in the 10 network available for devices in the 192 network - here I'm not quite sure. Do I need to a static route?
• Eventually I want to move all non-enduser devices to the new LAN so I can experiment without harming the family network but I want to make sure I understand it properly before doing that

I'd be glad for any hints on this, I'm a bit confused with the nomenclature here. If you have other ideas on how to approach this, I'm open for that too.

Hi guys,

Just picked myself up an EliteDesk 800 G6 SFF:

Current specs:

• CPU: i5-10500
• RAM: 8 GB
• NVMe SSD: 256 GB

My plan is to beef this up with:

• RAM: Crucial Pro DDR4 RAM 64GB Kit (2x32GB) 3200MHz

• HDD: 4TB ironwolf NAS drives * 2

• NVME SSD: Samsung 970 EVO Plus 1 TB PCIe NVMe M.2

How I'm planning my setup:

The existing 256 GB NVMe will host Proxmox.

The new 1 TB NVMe will be for VM's & LXC's

The 4TB ironwolf NAS drives will be configured in a mirror and will be used as a NAS (Best way to do this?) as well as for bulk data from my services, like recordings from Frigate.

Services:

• Home Assistant (Currently running on a pi4)

• Frigate (Currently running on a pi4)

• Pi hole (Maybe, already running on an OG pi)

• Next cloud (Calendar, photos)

• TailsScale

• Vaultwarden

• Windows 11

My follow on projects will be:

Setup PBS to back up my Host(proxmox-backup-client), VMS & LXC's

I have a Raspberry Pi 4 that I was thinking to use for PBS in the short term, but will eventually move it to something like an n100 mini PC.

I will also setup a second NAS(TrueNAS most likely, bare metal) to back up the 4TB ironwolf NAS.

This is my first proper homeLab, having mostly tinkered with Raspberry Pi's and Arduino's up to this point, any advice on my setup would be really appreciated.

Hi there good folks!

I am going to be upgrading my server within the next couple of months and am trying to do some prior planning. My current setup is as follows:

• Case: Fractal Define R5
• Mothberboard: Gigabyte Z170X-Designare-CF
• CPU: i7-6700K CPU @ 4.00GHz
• Memory: 32 GiB DDR4
• Storage: 15TB spread across 4 HDDs (10x2x2x1) + 1HDD at 10TB for Parity.
• OS: Unraid 🧡

While this setup as served me well, I am completely hooked on these mini-racks(Rackmate T1) and am thinking of getting one eventually. Fortunately I'll be getting my hands on my first mini-pc soon, an ASUS ExpertCenter PN52. This little badboy has the following specs:

• CPU: AMD Ryzen™ 9 5900HX
• Memory: 32 GiB DDR4
• Storage: Comes with one NVMe SSD 1TB

From my little cpu knowledege this one is superior in almost all ways, so it feels like an easy choice to swith out the old one. I need an enclosing for my 5 HDDs that connects to this minipc. This leads me to my questions:

1. What are your suggestions for enclosings?
2. Whats the best way to connect an enclosing like this to the mini-pc?

Any pinpointers, opinions and suggestions appriciated!

edit: im getting the mini-pc for free actually, so feel like its a no brainer to upgrade.

Pictures of the mini-pc for those interested:

Ports overview

Front

Easily configurable

I recently generated a self-signed cert to use with NGINX via it's GUI.

1. Generate cert and key
2. Upload these via the GUI
3. Apply to each Proxy Host

Now when I visit my internal sites (eg, jellyfin.home) I get a warning (because this cert is not signed by a trusted CA) but the connection is https.

My question is, does this mean that my connection is fully encrypted from my client (eg my laptop) to my server hosting Jellyfin? I understand that when I go to jellyfin.home, my PiHole resolves this to NGINX, then NGINX completes the connection to the IP:port it has configured and uses the cert it has assigned to this proxy host, but the Jellyfin server itself does not have any certs installed on it.

I was looking to see what would happen on the 3rd floor with a ceiling-mounted AP on the 2nd floor. New to Unifi, I keep being surprised with delight how much useful tooling & info there is.

Here's for the U6+:

I brought a Grandstream GWN7711P switch a while ago but I have found a rather annoying problem.

When the switch does not have an internet connection it is spamming "router.gwn.cloud" every 2-5 seconds and filling my firewall logs (360+ times in 35 min).

Does anyone know how to disable the cloud connection?

Hi everone, basically what the title says. I am just starting my homelab and I am somewhat conflicted on whether I should run Opensense in Proxmox or should I buy a n100 device dedicated for it. What are some of the pros and cons of doind either or. So far in my research I have only come across articles/forum posts explaining how to run Opensense in Proxmox.

I recently setup SearXNG to take the place of Whoogle (since Google broke it by disabling JS free query results). I am following the same steps I've always done in adding a new default search engine.

Navigate to the address bar, right click "Add SearXNG" then go into settings and make it my default. After doing this, rather than using the local IP the instance is running at, Firefox uses https://localhost/search for some reason. I don't see a way to edit this in the settings section of Firefox. Anyone else experienced this?

Update: After updating the .env file with my IP address and bring docker down/ up, all is working as expected (able to use SearXNG via Caddy using the https:// address)

For years, I have been using Whoogle for my self-hosted searches. It's been great, but recently there were some upstream changes that seem to have broken it.

I'm guessing that SearXng will soon follow (based on the assumption that they too are using the JS free results Google used to provide).

Does anyone have any self-hosted search options that still work? I hear Kagi is good for paid/ non-self hosted options, but just curious what you all are using.

I'm looking for options to replace my 2-bay DS214play after 10 years of service and I'm looking for recommendations on what direction to go. My main reason for retiring the NAS is that the OS will see no further updates from Synology, and not much will run on i386 architecture.

I run truenas + docker on a NUC-like HM90 mini-pc which is attached to the NAS for storage and this has been working well for the past ~2 years.

I figure that my options are to either continue using the mini-pc with a form of "dumb" network storage, or replace both systems with something that can handle both workloads.

I've considered building my own SFF PC instead of buying a new NAS (as this would have better upgrade paths), but I haven't been able to find anything with space for HDD which will also fit in the 10" cabinet that both of the above systems currently share.

The new NAS lineup from ugreen (DXP2800/DXP4800) seems like reasonable options, but I'm wondering if there's other options I should consider instead, as these models will only barely fit on the cabinet shelf (250Hx210Wx250D).
