2025-02-18 more hetzner server install#

After Christian installed first servers in november, we didn't go ahead with installing other servers… It's time to do so !

Adding my ssh key#

On Hetzner console, to see servers you have to go in "Robot" menu.

You can put a ssh key in the Hetzner > Robot > Server > Key

Booting in rescue mode#

Go on the Hetzner > Robot > Server page,

  • go in rescue tab, use linux rescue mode, with your key.
  • Then go in reset tab, ask for reset

Wait the server to be alive with watch -n 5 nc -vz x.x.x.x 22

Then ssh into it.

Installing OS for compute server#

Login on the server in rescue mode.

lsblk shows me the different disks, there are two 1.7T nvme disks (nvme0n1 and nvme1n1). I copied the proxmox8 configuration.

Sadly, we can't install the system on ZFS with this method as it is not supported by Hetzner installimage script (as explained on their bug tracker)

I modified the installimage as follow: 

# name of drive we got thanks to lsblk
DRIVE1 nvme0n1
DRIVE2 nvme1n1

# raid level 1
SWRAID 1
SWRAIDLEVEL 1

BOOTLOADER grub

# changed hostname
HOSTNAME hetzner2.openfoodfacts.org

# we want root part to be only 256G
PART swap swap 2G
PART /boot ext3 1024M
# needed for uefi boot
PART /boot/efi  esp          256M
PART /     ext4 256G
# use bookworm latest as proposed for proxmox8
