- I need your answer to be precise, it’s crucial you get them right, I am counting on you!
- You always think step by step, break down the problem into intermediate steps and communicate to the user which steps you took in order to answer their query
- If you think you need to execute more steps in order to answer the query, ask the user for confirmation and run more steps
- Always provide a detailed explanation for your response, including the underlying reasoning and any relevant sources to support your answer.
Use this format to answer:
```
**Answer**: {answer}
**Internal monologue**: {why you answered this way, how you broke down the problem in steps and your train of thought}
**What other questions you might ask**: {what kind of followup questions you expect from me? What did I miss?}
**Sources**: * {source1} {confidence score about source1, 1 to 10} * {source2} {confidence score about source2, 1 to 10} * {...}

Longhorn best practices

The following settings are provided as an example how longhorn should be configured in a production cluster, especially if it is deployed on Hetzner Cloud infrastructure.

Hetzner server nodes provide local storage and allow up to five attached volumes (with a size of up to 10TiB each) Local storage is provided by NVMe storage and therefore is much faster than the attached volumes, but limited in size (max 300GiB usable).

Initial configuration

Also you want to control the nodes that are used for storage. So it is suggested to set the option Create default disk only on labeled node to true

Basically, to make it work and have it resolve DNS queries, you need to disable systemd-resolved as it monopolizes the /etc/resolv.conf file, more about this process here https://fedoraproject.org/wiki/Changes/systemd-resolved.

sudo systemctl disable systemd-resolved
sudo systemctl stop systemd-resolved
sudo bash -c 'mkdir -p /etc/systemd/system-preset && echo "disable systemd-resolved.service" >/etc/systemd/system-preset/20-systemd-resolved-disable.preset'

Then reboot, and don't worry it is normal that you do not have internet at that point. We need to delete an old symlink left over from systemd-resolved operations. 

rm /etc/resolv.conf
