  • Filesystem and virtualization decisions for homeserver build

    Jump

  • I guess I'll give it a spin. There seems to be a big community around it. I initially thought I might migrate later so keeping the host OS layer as thin as possible. Ubuntu was mainly an easy start as I was familiar with it from before and the spirit in this initiative is DIY over framework - but if there's a widely used solution for exactly this.. Yeah.

  • Always a good reminder to test the backups, no I would not sleep properly if I didn't test them :p

    Aiming to keep it simple, too many moving parts in the VM snapshots / hard to figure out best practices and notice mistakes without work experience in the area, so I'll just backup the data separately and call it a day. But thanks for the input! I don't think any of my services have in-memory db's.

  • Right, thanks for the heads up! On the desktops I have simply installed zfs as root via the Ubuntu 24.04 installer. Then, as the option was not available in the server variant I started to think maybe that is not something that should be done :p

  • Aight thank you so much, confirms I'm on the right path! This clarifies a lot, I'll keep the ext4 boot drive :)

  • Right, so my aversion to live backups comes initially from Louis Rossmann's guide on the FUTO wiki where he mentions it's non trivial to reliably snapshot a running system. After a lot of looking elsewhere as well I haven't gotten much hints that it would be bad advice and I want to err on the side of caution anyway. The hypervisor is QEMU/KVM so in theory it should be able to do live snapshots afaik. But I'm not familiar enough with the consistency guarantees to fully trust it. I don't wanna wake up one day to a server crash and trying to mount the backed up qcow2 in a new system and suddenly it wouldn't work and I just lost data.

    It won't matter though as I'll just place all the important data on the zpool and back that up frequently as a simple data store. The VMs can keep doing their nightly shutdown and snapshot thing.

  • Ok so wrapping my head around this, what I think I need to be clear about is the separation between applications and data. Applications get the nightly VM snapshot way of backing up, and data will get the frequent zfs snapshots (and other backups). Kinda what I tried to do to begin with, so I will look more on how to do this separation for the applications I intend to use.

    Still unsure if samba is the way to go for linking it together on the same physical machine.

    Should I just run syncthing on the bare metal host...? Will sleep on it.

  • This is what I'm doing currently, but it's not really feasible to have the services shut down hourly for snapshots. This is indeed why I started looking towards filesystem-level snapshotting Obviously I will have other types of backups as well, I'm simply looking to have the on-the-fly immutable snapshot capability here somehow.

  • Thanks! Can I ask what is your setup like? ZFS on bare metal? Do you have VMs?

  • Filesystem and virtualization decisions for homeserver build

  • Fair about the SSD life. How would you go about achieving the frequent backups without zfs? I wouldn't want to implement it separately for every app I use, though I'm open to it if this doesn't work out.

    I'll easily buy more memory if needed, the box now has 8GB and isn't struggling in any way.

  • One does really not have to believe such things at all to be influenced by such platforms, especially if there is intent behind controlling its algorithm. Do you understand how recommendation systems work ans why them being black boxes is so dangerous on a big platform like TT?

  • In the West yes, people can obtain information on the internet.. But will they?

    With declining economy and increasing disinfo, we don't have the time to sift through all the nonsense and obtain the actual facts. We might as well be living in China.

    Did you follow what happened when a lot of American TikTok users made a trip to Rednote, a Chinese lifestyle app, to escape the looming ban earlier this year? The Americans discovered that a lot of what they knew about China was propaganda. The Chinese, to their horror, discovered what they knew about America, that they assumed to be propaganda, was correct..

  • I.e I disagree; free speech only exists if we specifically reject speech that aims to suppress free speech, while accepting speech we don't like but that doesn't aim to suppress.

    Can we do that? Can we draw the line? Why do so many believe there is no line to be drawn here?

  • Popper's paradox of tolerance gives in my view pretty clear guidelines on what to protect and what not to tolerate. I believe that if we held onto that, fascism would have a much harder time.

    I am not an expert on political science, so I don't know what the data tells us. The feeling I get from the world though is that the "impressionable" part is large enough to be consequential, in part because the "educated" part has already made up their minds.

    It's also not sufficient to talk specifically about ads in tiktok without considering them in the wider context of online messaging, all of which is going to be systemically tailored to feed into the same fears and shame.

  • What makes it tricky is, I think, that there are both kinds of voters so both viewpoints are kind of correct but piss the other side off with the implications. E: typo
