Also Noctua stats that the CPU cooler should only be used with care on CPUs with more then 65W, your CPU has 95W: https://noctua.at/en/nh_l9i_tdp_guidelines

Hey, A NAS is a Network Attached Storage, so the goal of it is to have it connected to the network and not just a single device else it would use an USB connection or sth. Similar. 🙂 You can connect your PC directly to the server, but that is not the intended use case and requires some setup. The Internet connection also does not play a role in this case, the only important thing is the internal network and as long as you have a cable connection, the internal network should be fast enough. The recommended way in your use case is to connect your NAS and PC to the network instead of each other directly. If you have multiple ethernet ports in your wall outlet you can connect both devices separately, if you have only 1 port, you can add a switch, and then connect both PC and NAS to this switch. This way, every device on the local network (PCs, Smartphones, TVs, TV Media Player etc.) can access the NAS for backups and reading/streaming.

I just had a brief look, but this looks to be very interesting, both the article and the tool. This will definitely help with understanding ZFS better! Thanks for posting it.

First of all it seems to be a very thought out setup which will be a good inspiration for the community in general. But you are running Proxmox (so do I) and a Proxmox Backup server (which I also wanted to have a look at), you have some scripts running, Uptime Kuma will be one of the apps which I will now also install and in general seems like there's a lot to learn. Also you have a Rack. I want a Rack as well.

You absolutely need to create your own topic. From your posts in the forum it sounds like you have a some things which I will shamelessly copy from your setup =D

We need to distinguish between the boot drive dying and some other HW dying. If something else dies, you just switch HW and you are good to go. If the boot drive dies or you reinstall hexos from scratch it's a bit different but those 2 scenario are functionally the same thing. Since Hexos currently doesn't support pool import during installation and is insisting on creating new pools, this currently not that easy to do with hexos. With Truenas (and hopefully Hexos as well once pool import is supported) it's as easy as it gets. You just need to backup your truenas config (no need to backup the boot drive), then you just reinstall truenas, you import your config and the system is up and running as if nothing ever happened. This is working because all the information about the pools and apps are stored on the pool drive itself and the boot drive only contains your config.

If you have an use case for additional VMs just go for it. However be aware that you have an additional layer which needs to be properly setup and configured and that some things might not be as straightforward as with a bare metal installation. 🙂

Pretty much exactly what @Sonic says. Hexos in a VM only makes sense if you want to run multiple OS on the same machine and if the VMs are the important part for you. If you primarily want a NAS and running other OS in a VM is not important and the built-in apps are enough for you, go bare metal there is no point in going down the VM part. If, however, VMs are important to you and Hexos is only a piece of your setup and not the most import part, proxmox or similar is the way to go.

If we look at the specs for the Seagate Ironwolf Pro, they are rated for up to 550TB/year, which is a ludicrous amount of data and which you will never write in the lifetime of the disk. I wouldn't worry about writing surveillance data to the drives, that's what the are ment for (writing and reading data 24/7) and it's likely not going to impact the life at all, or at least not in a significant way. Usually the other alternative for home surveillance would be micro sd cards and those die very fast compared to the lifetime off your surveillance setup and you need to swap them out every other year to be safe.

In Truenas under Data Protection there is an area for replication tasks, which is the preferred way to backup from zfs to zfs.

Lucky you, I had 3 HDDs and 3 SSDs dying on me, 1 HDD was DOA and have 3-4 HDDs with SMART errors indicating they will soon kick the bucket. 1 of the dead HDD and the DOA were WD Red (CMR) and Red Pro, all the other were consumer grade and I got plenty of lifetime out of them. Thankfully I never lost any important data or data which I cared about.

Hexos will write your USB Flash Drive to death very fast, that's why they are not recommended because of the constant writes which Truenas is doing to the drive (Logs, Graphs and the system dataset for the both drive). Also the performance might not be the best. It is definitely possible but you should definitely backup your system config regularly and don't wait multiple years before replacing the drive. 🙂

Hey, I just did 24h Mem Test, to be sure that the Memory is stable, but I didn't do any HDD burn in. My data is coming from a working NAS and I still have multiple copies of the imported files and I'm running a RaidZ2, so I'm taking my chances and hope that I'm not gonna lose 3 drives at the same time 🙂 Technically, I would need to loose at least 9 drives in various different NAS all at the same time before I start loosing my most important data. So yes, a dead drive is really more a nuisance at this point then a real issue with my current setup.

Used NAS are probably more expensive then used PCs. Also with an used NAS you might not have any upgrade possibilities. Additionally a Synology NAS will not work, because you are limited to there own OS. Also you nees to make sure to get a NAS with enough memory (RAM) and x86 CPU. So your best bet, in my opinion is to go for a PC, because there you have less restrictions and less things to worry about, only that it meets the minimum recommendation (especially the 8GB memory bit) and that it's not using a Realtek NIC (network chip, because most of them are not supported by truenas). Last but not least, don't forget that you need a dedicated boot drive, the boot drive cannot be used as a data drive, it only contains the OS and you cannot store anything on it. Ideally you would use a small SSD. A HDD would also work but not an USB stick.

Good point, I believe the same build with the 14600K and without dedicated GPU would be a good alternative for less demanding users and/or users on a tighter budget. Yes, I completely understand you there also some things just don't run on an iGPU, looking at you Immich...

Hey, yes this is not that difficult to do, I have done this in the past with various different NAS constellations. With Hexos you have 2 options: If you want to backup to another Hexos or Truenas you should use ZFS replication. (this is not your usecase) If you want to backup to a NAS which is not using ZFS you should do the backups using rsync. For rsync you need to configure both your Synology NAS as a server and your Hexos as a client (this needs to be setup in Truenas, Hexos doesn't offer this yet).

Mounting using fstab would have been my next advice, but I couldn't edit my post anymore so I was waiting for your feedback first. Keep us posted if it helps 😃

Hey, The problem with the high memory requirements is not directly Hexos or Truenas for that matter but ZFS itself. For example as a rule of thumb you need 1GB or memory for ever TB of storage, in your case that's already 7GB of memory. Then you also need 1/2-1GB for the write cache and additional memory for parity data calculation. So with your config you easily need 8-10GB of memory just for ZFS, add 1GB for Hexos and you see why the minimum required memory is so high and why you are facing issues with only 2GB of memory. Supporting low memory systems would require a lot of changes to ZFS which might result in suboptimal or bad performance.

Not yet, but the MMU3 support will come 🙂

Check out the new Prusa Core One with the MMU3. Checks all our boxes and it offers unparalleled upgradeablity. Prusa does offer an upgrade Path to the latest printer each time and this way to can easily upgrade and don't need to buy a new printer each time a new model is released.

Do you have the possibility to set the smb version? Can you force to use V3?

What distro are you using and can you share your fstab entry for the smb mount? (or however you are mounting your samba share)

Hey, you can use this raidz calculator, set number of disk groups to 1 and fill in all other numbers. If yoh have 3 or more disks hexos will create a raidz1, so you set this as raidz type and you get your usable storage in TB. (Don't forget to convert this to TiB) https://www.raidz-calculator.com/

In that case, use any gpu which you have at home for the initial setup or try do borrow one from a friend and check if the motherboard starts headless (without gpu) after the installation and if Hexos is accessible. If it is working fine without gpu after the setup you don't need to buy an extra gpu just for the server.

Hey @NaZzAtAzEr, What do you plan to do with your Hexos? Do you need the GPU only for video output or do you want to do some video transcoding with Plex/JellyFin? If you only need it for video out for the installation you can use any GPU and if you don't have one maybe you can borrow you from a friend. If you plan to do more with it, we need to know before we can give a proper recommendation.
