Server unreachable after using debian 11 script with raidz1

[ghost]

I'm trying to install a 10x10TB hetzner with raidz1 zfs i figured out how to modify the script to do this the script runs without error but after the server reboots its unreachable via SSH and also cant ping the server. Any suggestions on how i could fix this? Thanks.

KVM Console, check if the server is back up. Probably not.

No activity on the KVM, I did get this error when running the script: modprobe: fatal module zfs not found in directory /lib/modules/6.3.7

Finally I have found a setup that works for me, maybe it will be helpful:

1. Debian 12
2. Follow this steps grub-install: error: unknown filesystem #69 (comment), IMPORTANT to copy-paste code from step 4, not only add -o compatibility=grub2 \
3. Optionally set RAIDZ/RAIDZ2/RAIDZ3 instead of MIRROR by changing shell script like here master...AXYZE9:zfs-hetzner-vm:master or just change:

# shellcheck disable=SC2086
zpool create \
...
  -O mountpoint=/boot -R $c_zfs_mount_dir -f \
-  $v_bpool_name $pools_mirror_option "${bpool_disks_partitions[@]}"
+  $v_bpool_name raidz "${bpool_disks_partitions[@]}"

# shellcheck disable=SC2086
echo -n "$v_passphrase" | zpool create \
...
  -O mountpoint=/ -R $c_zfs_mount_dir -f \
-  $v_rpool_name $pools_mirror_option "${rpool_disks_partitions[@]}"
+  $v_rpool_name raidz "${rpool_disks_partitions[@]}"

4. Optionally run apt update after OS installation, in my case I have such error:

W: Failed to fetch https://deb.debian.org/debian/dists/bookworm/InRelease Temporary failure resolving 'deb.debian.org'
W: Failed to fetch https://deb.debian.org/debian/dists/bookworm-updates/InRelease Temporary failure resolving 'deb.debian.org'
W: Failed to fetch https://deb.debian.org/debian-security/dists/bookworm-security/InRelease Temporary failure resolving 'deb.debian.org'
W: Failed to fetch https://deb.debian.org/debian/dists/bookworm-backports/InRelease Temporary failure resolving 'deb.debian.org'
W: Some index files failed to download. They have been ignored, or old ones used instead.

I found this answer helpful, just echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

can you help to check this script works or not? https://github.com/congzhangzh/daily-scripts-4-us/blob/main/zfs-root-on-linux-4-debian/hetzner-debian12-zfs-setup.sh @abionics abionics

maybe you can do the test in the Virtual Box first :)
