I have found that the fog generating alarm systems are the ones that will stop burglars in their tracks. If they can't see, they're not going to hang about and if they've tooled up with NV then that's a whole different threat model.

I think the ZFS changes were due to needing a way to allow qnap systems to expand zfs pools. The raidz expansion features in openzfs probably took too long for qnap to wait.

OpenZFS released the zpool expansion as stable last year. Hopefully QNAP is charting a path to allow their users to migrate from their fork to OpenZFS, though of course these kinds of things take time to develop. I would be really worried if they are diverging further from OpenZFS rather than converging.

Last I looked at their releases of code, they had branched from ZFS before it became OpenZFS, and had a lot of proprietary extensions beyond just the reshaping (from memory, they implemented encryption differently, as one example, and I think they had one or two checksums that I assume were because something they shipped had hardware support for it?) so I wouldn't hold out hope that their goal is to rebase on OpenZFS unless they announce something to that effect.

Some years ago, there were mud-slinging myths being thrown around about ZFS. Things like "ZFS needs 1GB of RAM per 1TB of storage" and "it requires that RAM to be ECC" were once common to find online. These sort of thing seemed to lead to widespread beliefs that it was inefficient, expensive, and fragile. None of that is true, of course, but folks might remember and believe these myths and conclude that it is (or was…

I still got told that I need 16GB of RAM to migrate my 12TB btrfs array from a Synology with 6GB of RAM (2GB actually used) - by TrueNAS people. Are they wrong?

TrueNAS was major source of the myths

... because part of the company wanted you to buy their certified systems

Did we decide ZFS is good after all this time?

Who said it was bad? I thought we were all pretty much in agreement that it was good, and the only thing holding it back from wider adoption into e.g. the Linux kernel was the poison-pill of Oracle's ownership and licensing.

Actually the licensing issues were from Linux developers' side - Oracle has nothing to say (as the license to the code and patents was given before Oracle got their grubby hands), and Sun IIRC expected CDDL to work similar to the AFS precedent where non-derivative, non-GPL code was allowed into kernel.

The only lawsuit specifically about licensing was from few Linux developers through SFC who disagree with common consensus on how GPL applies in that case and sued Ubuntu for shipping ZFS as a module.

I have heard others say the same as you about Ubiquiti devices. I genuinely curious what bottlenecks you've hit. I've only been using Ubiquiti as a pro-sumer, but it has held up well for my use case of Plex and little game servers. I use a Synology NAS for my storage though, which is a slightly beefier mobile AMD chipset. I'd be very interested to know what I should and shouldn't expect from my ARM based network stac…

> I genuinely curious what bottlenecks you've hit. 1. My UDM Pro absolutely chokes and stalls with intrusion detection enabled on the firewall and 8 cameras connected. Network goes down, cameras disconnect, devices disconnect from Wi-Fi every time a car drives past a camera due to AI features triggering, etc. For something meant for small businesses I wish they would just shove an Intel i5 or something in it. They ma…

I have to agree. I only have a consumer UDM (four years old) and it's on its last legs. From day one it was using 90%+ of its RAM and hit the CPU ceiling during large file transfers. Successive updates have pushed it well beyond its limits. I have had to disable many features like VPN and IDS/IPS. I was considering upgrading to the newer Dream Router 7 but the processor is not much of an upgrade, and it only has 3GB of RAM vs my current 2GB. I don't have space for a Pro and I'm not even sure I want one. I already have an Unraid server running with more than enough compute and RAM, and I'm going to try using OPNsense. I would prefer dedicated hardware but for the cost, it's just not worth it.

The biggest concern about Ubiquiti to me is still its software/infrastructure quality. Off top of my head, besides all the UI/UX glitches: - They once allowed a human employee to access static AWS root access key. - Their employee once claimed "remote access" was end to end encrypted, but later people figured out they probably just meant TLS in transit. - They had a configuration error that allowed some users to acce…

I sold my Unifi APs, they broke DHCP over wifi multiple times. If you can't QA/Test basic 101 features like that, I have zero trust in your security.

What did you replace them with? I am starting to look into alternatives my self as I can see the noose they have around their user's neck's slowly starting to close.

And those classes available for the public has less voting rights than Elons stock so even worse.

So man makes company, man shares profitability of company with world to invest in. World complains they can't outvote man.

Some of the details you are missing here matter quite a lot.

I have, in pre-COVID days, though. The total bill including a skylake xeon E3-1285 v6 CPU, 64 GB ECC RAM, and the supermicro X11 board + chassis ( https://www.supermicro.com/en/products/archive/chassis/SC836... ) was under $1k.

The world changed. Massively. Reprice everything you're benchmarking pre covid.

Yes I know, but not by 4x. You can buy a lot of real compute for $4k, not an arm box with 16 disk bays.

Don't buy a QNAP if you care about real ZFS. https://news.ycombinator.com/item?id=48593360

> You can not take a zpool out of a QNAP system and access it on another system with ZFS.

Too bad... I always wonder why companies do this...

heh, i'm afraid that smell will linger on longer than you want to try in a building used as living quarters... :)
