CEPH HA Setup

Note this should only be done once you are sure you have reliable TB mesh network.

this is because proxmox UI seems fragile wrt to changing underlying network after configuration of ceph.

All installation done via command line due to gui not understanding the mesh network

This setup doesn't attempt to seperate the ceph public network and ceph cluster network (not same as proxmox clutser network), The goal is to get an easy working setup.

**2025.04.24 NOTE: some folks had to switch to IPv6 for ceph due to IPv4 unreliability issues, we think as of pve 8.4.1 and all the input the community has give to update this set of gsists - that IPv4 is now reliable even on MS-01. As such i advising everyone to use IPv4 for ceph as if you have IPv6 you will have issues with SDN at this time (if you don't use SDN this is not an issue).

Enable PipeWire on Ubuntu 22.04

This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like pipewire-debian, you might get into conflicts.

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

Pip is a package manager of python. You can download Python libraries from some Python repositories like PyPI. You can also download libraries from a git repository. This is gonna be the issue to be explained in this article.

I don't like to memorize things all the time. So, I guess, I couldn't be working without internet :). Whenever I need to install some python libraries from a git repositories, I see a lot of way to do it. It is really confusing. This should be the reason why I can't memorize it. I can see how a very simple requirement is handled with to many confusing way. There shouldn't be to many way. Some of them is not working neither. At last, I decided to blog it.

As you may know, you can use two protocols which are http and ssh to do something on git repositories. Using protocol ssh instead of http may provide some ease of use. Because of nature of ssh, you can do something with your primary/public keys. So, you don't have to input your credentials all the time. But I'll be
