@dandellion:dodsorf.asDandellion * maybe it's related to #177660 22:12:58

@kenran_:matrix.orgkenran_ I'm looking to replace a Hetzner Cloud VM that Hydra is running on with a dedicated server (in order to be able to use /dev/kvm). Do you know if https://nixos.wiki/wiki/Install_NixOS_on_Hetzner_Online is still up to date? 06:53:52
@kenran_:matrix.orgkenran_

In particular, it links to a script mentioning

# * **Important:** We boot in legacy-BIOS mode, not UEFI, because that's what Hetzner uses.
#   * NVMe devices aren't supported for booting (those require EFI boot)
06:55:14
@kenran_:matrix.orgkenran_ Hetzner for a while now mentions that they support UEFI boot natively. But I don't know what UEFI Rescue System is currently in the beta stage. means in this context. 06:57:16
@kenran_:matrix.orgkenran_I'm wondering if I can now order an small NVMe-using dedicated server there and install NixOS on it without ordering an additional HDD.06:57:56

Probably that the web-KVM environment is in a beta phase

@rick:matrix.ciphernetics.nlRick (Mindavi)So if you lose access you may run into issues accessing via the web kvm07:14:00

I haven't ever actually used a dedicated server there, so I'm a bit anxious. I'd probably try the Bootstray from the Rescue System approach described in the Wiki above. Is that a good idea?

@rick:matrix.ciphernetics.nlRick (Mindavi)Hopefully someone else can give some insight, I don't know that much about it otherwise07:24:17
@kenran_:matrix.orgkenran_Thanks!07:31:47
@kenran_:matrix.orgkenran_I'm just a little hesitant right now, but since the servers are payed hourly, there's probably not that much of a risk to just trying.07:44:50
@sandro:supersandro.deSandro I would just give it a try 🙃
Worst case you need to rebuild your cache but there shouldn't be any data loss.

@kenran_:matrix.orgkenran_ Seems to have worked with some tiny changes (sudo wasn't there, slightly different commands and such). Woo! 08:29:38
@florian:web3.foundationFlorian | W3F changed their display name from Florian | W3F to Florian | OoO till 20.06..09:21:15
@linus:schreibt.jetzt@linus:schreibt.jetzt kenran_: huh, the dedicated servers aren't billed hourly..? 12:37:50
@linus:schreibt.jetzt@linus:schreibt.jetzt kenran_: are you talking about "dedicated" Hetzner Cloud instances? Because those aren't actually dedicated machines, they're just VMs with reserved CPU capacity 12:39:17
@linus:schreibt.jetzt@linus:schreibt.jetztin any case, if you want UEFI boot on the "real" dedicated servers (ordered via robot.your-server.de, not console.hetzner.cloud, billed monthly) you need to open a support ticket iirc.12:40:30

you can enable it yourself through the remote kvm. you need to get access to the kvm through a ticket, though.
12:41:08
@linus:schreibt.jetzt@linus:schreibt.jetztEither to get support to enable UEFI boot for you, or to get a KVM console through which you can access the firmware settings12:41:13
@linus:schreibt.jetzt@linus:schreibt.jetztI think if you get support to enable it for you, they might also do something with their netboot setup so that the rescue system still works for you? I'm not sure if that's needed or not12:41:50
@linus:schreibt.jetzt@linus:schreibt.jetztI'd recommend ordering a KVM console for the setup either way, because especially if you're doing it for the first time you're likely to end up needing it and it's nice not to have to wait for it in those situations :)12:42:38

Hum, are you sure? I could cancel the first one I ordered, it was removed instantly and a German FAQ entry seemed to say that we wouldn't have to pay the full amount.
13:21:20
@linus:schreibt.jetzt@linus:schreibt.jetztWhat server type was it?13:21:43
@kenran_:matrix.orgkenran_The smallest there is, AX41-NVMe.13:22:27
@linus:schreibt.jetzt@linus:schreibt.jetzthuh ok13:22:47
@linus:schreibt.jetzt@linus:schreibt.jetztthat's news to me, but good to know!13:22:51
@kenran_:matrix.orgkenran_I cancelled it because I thought installing and booting NixOS wouldn't be possible, and now ordered a 2nd one after trying it out and getting it to work.13:23:14
