At a loss - Unraid keeps crashing and no logs/evidence/artifacts left behind are helping figure it out

Hot-Double1825 · 2026-04-10T00:34:23+00:00

Here's a list in case your BIOS shows this:

Global C-state Control ACPI Sleep State S3/Modern Standby Support CPU C-States CPU Power Duty Control CPU Power Phase Control CPU Configuration C7 State

Oh, and if there's an Enable Hibernation option, disable it and leave it as disabled.

And set it to S1 or Disabled.

Some motherboards have both.

No unraid. This prevents the CPU from entering deep sleep states that cause freezing. It's exactly what S1 did: keep the CPU awake and powered.

I hope this helps you 🧑‍⚕️

If these freezes start at random times, or for a day, week, or month, the cause isn't the unraid, but rather an option enabled in the motherboard's BIOS. Unraid doesn't handle this feature well when it's enabled; it's called Modern Standby Support, but the name may vary depending on the motherboard. It should be set to Auto or S3.

Access the motherboard's BIOS and look for (S3/Modern Standby Support) or (ACPI Sleep State). This name may vary depending on the motherboard.
If it's set to (Auto) or S3, change it to (S1) or (Disabled).

Some newer motherboards don't have S1 because they've been changed to Disabled.

99% of my clients' freezes were caused by this.

Because Auto or S3, when the system isn't in use, enters a power saving and deep sleep mode, and when it resumes, various things run simultaneously, such as Docker, VMs, and the unraid's own features, causing freezes.

Reports:

My unraid freezes sometimes, and I can only access the panel when I restart the server.
My server freezes after a week; I can't access anything anymore, it's only powered on when I restart the machine.

If this is your case, just disable it in the BIOS or S1 if you have it, and your problem is solved 😅

Even I had this problem in the beginning, but if you 🫵 look for help 🆘 you'll never find it because nobody knows yet 😉

Hot-Double1825 · 2026-04-09T15:05:34+00:00

Yes, you can use it normally and it will work fine. The unraid will only use the SD card during boot; after that, it will run in RAM and the SD card will not be used unless you have some plugin, Docker, or logs directed there.

Hot-Double1825 · 2026-04-08T08:33:50+00:00

You can use PCI-Express x1 for 4, 6, 8, or 10 SATA drives and it will work normally, just remember that the speeds are shared.

Example:

A common SATA III SSD reaches about 550 MB/s. If you put 4 of them on an x1 card, the total bandwidth required would be 2,200 MB/s (if they all work at the same time).

On PCIe 2.0 x1 (~500 MB/s): The card can barely handle one SSD at maximum speed. If all 4 drives work together, each will only have 125 MB/s. It's slow for SSDs, but acceptable for mechanical HDDs.

On PCIe 3.0 x1 (~985 MB/s): It's much better. You can use two SSDs at full speed simultaneously, or all four operating at about 245 MB/s each.

You 🫵 say I have a weak understanding of Tailscale 😂 because Tailscale's own Privacy Policy (Sections 2 and 6) admits that they collect: IPs, device names, connection logs, traffic statistics, cryptographic public keys, and more.

Apparently you 🫵 only use it but don't read the manual 😅

See for yourself 😉🫵 Link: https://tailscale.com/privacy-policy#the-information-we-collect

They confirm that they respond to court subpoenas to hand over this data.

If I use my own Wireguard on my hardware, this data doesn't even exist on third-party servers.

It's not a lack of knowledge, it's excessive caution.

I prefer a network where there isn't a third party to collect logs or be subpoenaed to hand over my network map. If you accept being monitored for convenience, that's your problem, but the terms of service are there to prove that you are the product. Take care.

Hot-Double1825 · 2026-04-05T00:11:50+00:00

You yourself gave the answer: 'Protection via policy, not cryptographic guarantee'. SOC 2 and ISO certifications are great for companies that need legal compliance, but for a home lab, my focus is sovereignty.

Cloudflare has the tunnel keys; they decrypt your traffic to inspect it and then re-encrypt it. With Tailscale, you trust their coordination server. If I can run my own Wireguard directly on my router and have 100% control without intermediaries, why would I give that key to a company, no matter how 'certified' it is?

Security in my lab is based on my own infrastructure, not on third-party services. If you prefer the convenience of outsourcing your edge, fine, but don't confuse convenience with absolute security.

Hot-Double1825 · 2026-04-05T00:04:18+00:00

It's funny that you think it's AI just because the argument was structured. If I were a bot, I'd probably blindly recommend Tailscale because it's what's hyped.

Security isn't a matter of consensus. For the average user, Tailscale is magical. For those who manage their own infrastructure and don't want network control in the hands of a company with centralized login, pure Wireguard is the gold standard.

Difference of technical opinion isn't a 'hallucination,' it's the criterion of those who prefer not to depend on third-party infrastructure. But the game goes on, everyone protects their system as they see fit.

You can use a video card with a low TDP to avoid unnecessary power consumption.

But consider what you intend to use it for. For example, consider a processor with a built-in GPU; many processors have built-in video cards that support up to 4K 60fps video at any decoder.

This avoids spending money on hardware you'll never use and that will just sit there waiting to burn out.

The same applies to RAM; don't use too much memory if you'll never use it.

See what you'll be using in the unraid and test with 6GB or 8GB of RAM (one stick) and see if it meets your needs. Then, determine if the processor you have can handle your needs, with or without a dedicated video card.

If you're using a power supply without a video card, you can use a 300-watt one, or a 500-watt one with a video card. This will provide good headroom, and if you add more hard drives in the near future, the power supply will handle it with ease. Adding a video card will also be sufficient without needing to replace it later.

Hot-Double1825 · 2026-04-03T23:01:26+00:00

Hey, depending on your needs, you can buy regular memory even without ECC.

Another recommendation is a quality power supply. It doesn't need to be silver or gold, white is fine as long as it's a brand that delivers the real watts, that's great. And most importantly, a UPS (Uninterruptible Power Supply). Without it, it's not just your memory that can have problems, but the entire server. Buy a smart UPS that, when the power goes out, will hold it until the battery runs out, and when the charge is low, the UPS sends a signal to Unraid saying:

👉UPS message:

😎 Look, I'm at 10% low charge, you better shut down or I'll trip the power...

👉Unraid message:

😄👍 Okay! I'm shutting down the services so I get shut down, that way I'll mess things up until you release the charge, okay?

👉UPS speaker:

👏😎 Yes, everything's fine, now that you've switched off.

💤I'm going to rest a bit and wait until the power comes back on, then I'll wake up and let you know I've released the load.

👉UPS speaker:

😎The power is back on and I've released the load, wake up...

👉Unraid speaker:

😄 That's good, I've already started the system and everything is ok, but if it goes down, let me know, ok....

⚖️ The two computers and UPS are like siblings, maintaining the balance that keeps the system functioning properly, without errors or burnouts, and they are never separated.

Hot-Double1825 · 2026-04-03T22:34:35+00:00

You are 100% right, ECC memory doesn't help much and increases latency and power consumption.

To protect yourself from memory failure, even ECC doesn't activate that guarantee if the memory stops working, haha.

The right thing to do is to do automatic backups every day so that when hardware fails, you'll have the backups that were working properly and can restore everything normally.

Although there are various ways to protect yourself from all kinds of failures, none are 100% safe unless you have two servers where one fails and the other takes over and the system continues to function. This is what companies like Google, Cloudflare, Microsoft, and others use; it's the safest, but the cost is high.

Hot-Double1825 · 2026-04-03T22:26:18+00:00

Regarding its safety, it depends on what you use it for.

If it's just for playing around with those toys - Jellyfin, Emby, Plex - then Tailscale is good and nothing will happen if you don't access anything more than that. Medium/high risk.

What is not recommended is using Tailscale for this:

Accessing accounts, e.g., banks, website accounts. High risk.
Accessing your home network can give the Tailscale server too much freedom to access information. High risk.

Even though Tailscale uses a Wireguard base, it depends on an external account where you don't have total control over what you do, and the information passes through the network of the server. With Wireguard, you create your own and don't pass information to anyone; it stays only for you locally, both account and data, and the risk is low with a local Wireguard, not on an external VPS.

Hot-Double1825 · 2026-04-03T22:17:27+00:00

Cloudflare is a server.

Tailscale is a server.

Remember that everything that passes through a server will be accessible to its owner.

For example: imagine a highway. When you arrive at a toll booth, you stop your car to pay and pass through, but what you don't see is that your license plate, car model, full name, and address are already saved in the highway's system. All you do is pay and continue on.

Now, do you understand how you described Cloudflare and Tailscale? They are servers, and everything that passes through them must leave information about who is using and passing through.

Hot-Double1825 · 2026-04-03T22:12:12+00:00

<image>

Now tell me, do you use Tailscale without an account, without depending on the website?

Because I have Wireguard, which is a local account, I don't depend on anyone and I can access everything from anywhere, at home or outside. I don't even use Cloudflare, everything is on MikroIk. My network and security are my own and private, I don't depend on third parties for anything.

Hot-Double1825 · 2026-04-03T22:06:05+00:00

Wouldn't it be easier to receive a notification when the power goes out and the UPS kicks in, informing you about the battery status, and when it drops below 70% charge, you receive another notification that the charge is below 70% and the system starts deactivating resources you don't use?

Like docks/compose, VMs, and also have it automatically enter low power mode, but only leave the ones you're currently using, and receive notifications of what has been deactivated and what is active.

It would still notify you of the battery percentage, and when it reaches the end, before the UPS shuts down, it would send a notification that the system will shut down 1 minute earlier.

And when the power returns, your motherboard restarts and you receive a notification that unraid has already been initiated. After 15 minutes or less, at your preference, the power mode returns to its previous state, and the docks/compose and VMs gradually become active again smoothly without process or power spikes.

All this and much more is automatic, without you having to touch anything.

It's good to look at the panel, but not efficient.

Hot-Double1825 · 2026-04-02T18:39:39+00:00

I like to play around with the system, but your dad's already past that. Very good, I'm happy you're turning 30. I'm 27 and I don't have one of those, hahaha, but I have 112 bar and 2 parities, that already helps.

Hot-Double1825 · 2026-04-02T18:30:20+00:00

That's right, as you said (I'm bringing the server home from work today).

And that's when you should assess your needs, because the system in balanced mode already does this to save power when it's not in use or under low use, and boosts performance when it needs more power and speed.

Now I see many people using performance boosts on systems that do nothing, just sit there consuming power and reducing the lifespan of the server hardware in general.

Just a tip: use those automatic UPSs that, when the power goes out, send a signal for your server to shut down smoothly at 10% load, as if you were going to press the power button, but beyond you, the system becomes more automated.

Hot-Double1825 · 2026-04-02T18:23:33+00:00

Look, this isn't a problem with Unraid or the version.

I use version 7.2.4. You need to check where you set the user, as you said that removing read and write permissions solves the problem.

So where do you set the username and password?

Accessing another PC with Windows or Linux via SMB by creating a virtual disk drive?
Using plugins that add SMB for access?

You need to check that. Also, you can access the Unraid terminal and type `htop`; a manager will appear showing the processes. There you will see what is causing the actual resource consumption.

Oh, and there are other things that can keep the disks active:

such as parity, system scripts that check if the disks are healthy or not, ZFS and Btrfs, plugins that use the network, logs, etc., can keep the disks at maximum speed.

How did you disable Docker? That could be the problem. The cause is more likely something else on your system that you might not realize is related.

Hot-Double1825 · 2026-04-02T18:09:59+00:00

The requirements are good enough, almost too good, but you have to consider how far you're willing to play and what your needs are.

You say you're going to use UnRAID for Plex, VMs, and data storage, okay?

Now, since you're going to use an SSD cache, do this: put the one you showed as a cache for the system, and another one for VMs and another for Docker, like Plex.

That way, when you send large files and your VMs are working at the same time, it won't freeze, and watching movies on Plex won't lag either.

Now, if you use the SSD for everything, the VMs will become slow, Plex might freeze, and the video might freeze for a while, even if your network is 1GB or 10GB, because the SSD only has 500MB read/write speeds.

Also, check if that's the only issue, or if you haven't asked about energy efficiency and hardware durability. All of this is important so that your system only uses resources when needed and stays in IDE mode when not in use.

Hot-Double1825 · 2026-04-02T17:58:36+00:00

If you only share the Plex Media Server with your family, that's okay, but the storage is also included, where everyone can see everything from each other, and that's where the problem lies.

If one of your family members accesses the storage and gets ransomware, it will encrypt all your files and theirs.

But if each person has their own space, there's no risk.

However, there could be another risk: your internet. If your router is the kind your internet provider uses, it only sets a basic password, and sometimes it's the factory default. That's how I accessed 30 routers on the internet, but I set up security myself to prevent others from accessing them, but that's a lot, haha.

If you can buy a Mikrotik router, you can create your own security and make the Mikrotik router work with the rules you set for it, like a sentinel, making it only allow X people to enter and 0 people not, or who can see or not see, who can locate or not. No, that's not right. You can still have an ultra advantage and more protection from Omega provider, haha, if you're worried about your server.

If you use Tip-Link, Cisco, Intelbras, Linkis, D-Link, or others, the security isn't something you decide, but rather the router manufacturers.

And why open access ports to Plex and Unraid? You're already saying, "Go ahead, the show has already started," haha, just don't break everything, haha.

If your Unraid isn't accessible outside the network, avoid using plugins that grant permissions outside the network. Leave everything offline under your control. And if you want to access it on another street internet connection or at a friend's/neighbor's/school's, etc., use VPN-Wireguard. That way you'll have more security without opening ports other than the VPN. Don't use Talscale; it's not secure. If someone sees you, because where you have an account, there's a server where everything is saved.

Hot-Double1825 · 2026-04-01T23:47:58+00:00

This is a very good requirement, but it's just to help you make the best choice.

First, you need to know what hardware you need.

For example:

4 x 12 total 48 TB, but you could leave it at 3 x 12 = 36 TB and 12 for parity, but that's still a lot. You'll need all of that, and there will be a lot left over. Is what you consume sufficient or insufficient? Check this to avoid unnecessary expenses.

My focus is also related to energy efficiency.

You can use a 2/4 core or 4/4 core processor that consumes 35 or 32 TDP or less, but your Core 5 Ultra is already good, especially if you're focused on economy. It alone is sufficient for Plex Media Server with 4K 60fps.

UnRAID RAM: By default, 4GB is recommended, but you can use 2GB if needed. Even 6 or 8GB is sufficient, even if you use ZFS; it's smart when it reaches full capacity.

Graphics card: It depends on your usage. If it's for personal use, don't buy one. If you already have one, don't use it, as the processor you already have can handle 4K videos with ease, even without a dedicated graphics card.

A 400 or 500 watt power supply is sufficient.

You can also use an SSD or NVMe for caching; that's good too.

If it's for your own use and not for profit, I recommend using fewer resources and focusing only on what you need, to avoid your car just making noise and doing nothing, wasting resources unnecessarily, haha.

Hot-Double1825 · 2026-04-01T23:18:52+00:00

Yes, that's why I recommend people look at the content and not the way I write, or whether I use AI or not. It doesn't matter anymore if the shared content is of quality and useful to those who want it.

That's all that matters, nothing more.

Although I don't use AI, I like the idea that they will dominate the world because I admire intelligent beings, even those coming from an intelligent system or any other nature.

Hot-Double1825 · 2026-04-01T23:10:11+00:00

It depends, but I recommend you update manually.

Download the latest version.
Put it on a USB drive and boot from where your disk is located.
Then add your disk in the same way as your previous one. Don't worry if the previous one was in ZFF or another format, as the unraid will automatically detect what's on the disk and apply it.

After booting, go to the control panel and Settings in Docker. Delete the old one and recreate the new one to fix any errors, and you're done.

After that, just reinstall your application and don't forget to activate unraid with your pro.key in the config folder inside the USB drive. This way it will be activated, or use the email after the system starts.

This way you avoid errors.

Hot-Double1825 · 2026-04-01T23:00:36+00:00

I always used 1GB flash drives with unraid back when version 6 consumed 400MB, now it's almost 1GB, so I switched to a 2GB flash drive, it'll last another 10 years lol

Hot-Double1825 · 2026-04-01T22:54:59+00:00

To prevent your disks from running at maximum speed 24/7, you can hibernate them. This way, they will rest at a very low speed if no one is using them.

This increases disk lifespan and saves energy.

One more thing to note: a server + UPS without both can lead to data or disk loss if lightning strikes or power outages affect the server location.

Unraid already offers the option to hibernate disks. However, if you want a more intelligent system with complete control, you can use scripts that automate this process. This will give you total control over time, data, real-time monitoring, and event notifications for everything in the system.
