Fixed headaches with my proxmox backup server. It has a SAS-controller and 4 spinning drives running backups at detached garage and the old fujitsu desktop I dug out of office dumpster pile just kept crashing. Flashed controller to IT-firmware, updated bios on motherboard and did everything else I could figure out but the system just lost the drives pretty much daily and required a hard reset. Turns out, or at least that’s my conclusion, that the PSU on the machine just didn’t have enough juice for the whole setup and that caused instability. I dug out old (2010 or so) desktop from my own pile and threw 600W PSU on the box, it’s now been stable for at least a week.

I would’ve liked to keep the fujitsu-machine as it’s in a more compact case and couple of generations newer CPU, but that thing has propietary power supply so it was easier to swap out the whole system and just move drives from one to another. So, the current setup consumes maybe a bit more electricity, but at least it’s doing what it is supposed to.

Also known as Schrödinger’s Backup.

Zfs can become painfully slow if you don’t have RAM for it. I tried to run ZFS on my old setup with 64GB RAM and with moderate amount of virtual hosts and it was nearly useless with heavier io-loads. I didn’t try to tweak settings for it, so there might be some workarounds to make it work better, I just repartitioned all the storage drives with mdadm raid5 array and lvm-thin on top of that. Zfs will work with limited memory in a sense that you don’t risk losing data because of it, but as mentioned, performance might drop significantly. Now that I have a system which has memory to run raidz2 it’s pretty damn good, but with limited hardware I would not recommend it.

LVM itself is pretty trivial to move on a another system, most modern kernels just autodetect volume groups and you can use them as any normal filesystem. If you move full, intact, mdadm array to a new system (and have necessary utils installed) it should be autodetected too, but specially with degraded array manual reassembly might be needed. I don’t know what kind of issues you’ve been getting, but in general moving both lvm and mdadm drives between systems is pretty painless. Instead of mdadm you could also run lvm-mirroring on the drives so it’ll drop one layer off from your setup and it potentially makes rebuilding the array a bit simpler on another system, but neither approach should prevent moving drives to another host.

Lvm-thin is more flexible and while it might be a slightly slower on some scenarios I’d still recommend using that. Maybe the biggest benefit you’ll get from it is an option to take snapshots from VMs. Mounting plain directories will work too, but if your storage is only used by proxmox I don’t see any point in that over LVM setup.

Well, you’re not wrong, but that would still be a catastrophe modern world hasn’t yet seen. Those millions would become refugees and absolutely overwhelm European immigration system even with mass casualties due to riots, loss of water/food/medicine and who knows what else. Current oil prices would seem pretty cheap and global economy would take a massive hit causing homelesness, bankrupts, humongous loss of crops (due to fuel and fertilizer prices) and all kinds of havoc.

Global west would suffer badly, China would become even stronger, Russia would benefit from that as well causing even more problems around Europe. Global trade with USA would practically collapse and pull USA down as well. In the global scale it doesn’t even matter that much if there’s a nuclear explosion somewhere too as results will be pretty nuclear anyways.

For whatever reason ISPs tend (at least in here) to be pretty bad at keeping their DNS services up and running and that could cause issues you’re having. Easy test is to switch your laptop DNS servers to cloudflare (1.1.1.1, 1.0.0.1) or opendns (208.67.222.222, 208.67.220.220) and see if the problem goes away. Or even faster by doing single queries from terminal, like ‘dig a google.com @1.1.1.1’.

If that helps you can change your router WAN DNS server to something than what operator offers you via DHCP. I personally use opendns servers, but cloudflare or google (8.8.8.8, 8.8.4.4) are common pretty decent choices too.

Depends on what you’re looking for, but for server use even a bit older hardware is just fine. My proxmox server has Xeon 2620v3 CPU and it’s plenty for my needs. For storage I went with SAS-controller, controllers are relatively cheap and if you happen to have a friend in some IT department you might get lucky when they replace hardware. RAM is a pain in the rear, but 8GB DDR4 rdimms work still just fine (if someone is interested I have few around)

Personally I wouldn’t pay current prices for new hardware, specially if it’s for hosting. A bit older, but server rated, components give a lot more value for your money.

It seems like something so important that we’d have ironed it out, but the Constitution never explicitly laid out the terms, and it’s never been specifically answered by the Supreme Court.

I guess lots of the world have similar situations with different laws. Generally, when those are written no one really asked what if president/minister/whoever is bat shit crazy demented old guy and should the law have guardrails for that.

You can’t make a Lego drone. It’s not rigid enough.

You actually can make one mostly out of lego. Obviously not a really good one, but it can be done.

No deduplication, encryption nor support for non-linux operating systems for a start.

Not from my wife if I lose our photo collection which has been building up since we got our first digital camera 20ish years ago.

I have dynamic dns address and a handful of CNAME records on my domains pointing on that dyndns-address so I can use ‘proper’ names with my services. When my public IP changes it takes a few minutes for the records to update, but it usually happens only when my router reboots so it’s been good enough for me.

Also I use two separate dyndns providers so there’s likely at least one working DNS entry to my network.

I’ve always liked the way slashdot handles comment rating. It’s a bit complicated, so maybe that’s why it’s not adopted elsewhere, but it gives a much more fine grained options instead of just up/downvote.

ISP obviously don’t see the traffic inside your own network, regardless of the router used. But as soon as you open any kind of connection over the internet, incoming or outgoing, your ISP has to have some information about it to route the traffic. DNS over TLS doesn’t hide that your browser opens connections to servers, they can see if you use wireguard to access your services (not which ones, just in general that there’s traffic coming and going) and even if you use VPN for everything they can still see the encrypted VPN traffic and, at least technically, apply pattern recognitions on that to figure out what you’re doing. And if you use VPN then your VPN provider can do the same than your last-mile internet provider, so you’ll just move the goal by doing that.

Last-mile ISP is going to be a middleman on your network usage no matter what you use and they’ll always have at least some information about your usage patterns.

ISP can see your traffic anyways regardless if their router is at your end or not. In here any kind of ‘user behavior monitoring’ or whatever they call it is illegal, but the routers ISPs generally give out are as cheap as you can get so they are generally not too reliable and they tend to have pretty limited features.

Also, depending on ISP, they might roll out updates on your device which may or may not reset the configuration. That’s usually (at least around here) made with ISPs account on the router and if you disable/remove that their automation can’t access your router anymore.

So, as a rule of thumb, your own router is likely better for any kind of self hosting or other tinkering, but there’s exceptions too.

My now near adult kids have actually understood and been thankful that their childhood was ‘unfairly strict’ on what they could do on their devices. They have friends who have had unmonitored access to anything on their devices and it starts to show badly enough that even their peers notice how short their attention span is and how twisted their view of the world has become.

There are all kinds of laws regarding on how parents should treat their children and one might argue that keeping non-age appropriate material away from them is a reasonable line to draw into. For example in here with movies it’s pretty common practice (depending on a theater) to allow kids to ‘higher age bracket’ PG-rating with a guardian.

But the whole problem, at least from my point of view, can’t be solved only by either technological or legal barriers or solutions. Parenting is a tough job and from what I can see there’s really not enough support for them to do the job. “It takes a village to raise a child” used to be pretty commonly understood approach where all individuals from school bus drivers and cashiers played their small part on educating kids on how to behave and how the world works. Today it’s just rules and regulations which adults can use to hide behind and avoid taking any kind of responsibility and also, at least on some cases, the same rules say that you’re not even allowed to intervene if kids are being kids and do something stupid.

Obviously a lot of things are better now too than even in the 80s and 90s when I was a stupid kid, but I’d say something is also lost on the way.

I agree. It’s a bit tedious to configure, but rock solid and has all the features you could ask from a proxy.

If they actually worked, sure. I’ve been a parent for nearly 20 years now and at least in here there’s always been some kind of programs, information campaingns, news articles, tools and pretty much everything you can imagine to help keeping your kids safe. You obviously don’t buy porn magazines for your teens and don’t show news from war zones to your young kids and keep eye on the movies/shows they watch, but somehow every precaution is lost when it comes to the internet. I don’t know if it’s lack of understanding in general (as in what you can find from the net) or if it’s just the easy way out since you don’t need to learn how to apply limits on devices, but somehow (at least in here, based on what I’ve seen/heard) it’s not taken as seriously as PG-ratings on physical media.

And in that a system-wide setting on devices which would include allowed PG-rating on HTTP-headers (or equivalent) might be a decent solution. Obviously parents still need to pay at least some attention on the devices their kids use, but that wouldn’t require setting up a pihole on your network which blocks tiktok. However, as I said, that’s helpful tool to the parents only as long as it’s just a field on a local user account for the device, not something you’d need online services to verify.

Technically that would be pretty easy to implement and even if it’s just an extension to HTTP headers that would cover nearly all of the use cases today. Sure, the kids interested in tech could bypass that pretty easily, but that applies to nearly all of the parental controls anyways. But all those benefits obviously vanish if the age setting needs verification from someone else than the parent and it’s not stored just locally in the device. Building systems for adults to verify their age in order to look some bare nipples is a colossally stupid idea, but I’d guess nearly all of us here on fediverse already understand that.

A lot of parents sadly lack any kinds of skills to use those tools nor even know that they exist. I’m not inherently against the approach where user agent sends some rough age (allowed R-rating or something) to the website which can then block minors from accessing porn/violence/whatever. If it was just that, locally stored info if the user is minor or adult, it could be a pretty decent approach to even technically less inclined parents to give some limits on what their kids can do.

But as with nearly every ‘protect the kids’ thing, it’s a pretty damn slippery and steep slope. If adult verification requires something more than a local variable that’s the point when the whole system becomes a tool for surveillance instead of a helpful thing for parents/schools and all of these “solutions” worldwide seems to be going in that direction.

“They intentionally had schoolgirls in a school for girls that we were targeting with missiles in order to give the other guys something to whine about”. I don’t know what kind of twist in thinking you’d need to make that sound perfectly legitimate and good reason.
