ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

Purpose of Proxmox cluster project

Required Outomces of cluster project

Run Proxmox Backup Server (PBS) on a Proxmox VE host

Rather than set up even more infrastructure, I run Proxmox Backup Server on the same machine that's running a Proxmox VE host.

Install Proxmox Backup Server

Open a shell on your Proxmox VE host. We'll be installing PBS alongside Proxmox VE at the OS level. We will NOT run PBS inside a container.

Before starting, make sure you have a backup, and make sure to have a linux live boot ready to rescue your system. It's easy to mess this up!

Use gdisk to convert the partition table to GPT.

gdisk /dev/sda
Create the "BIOS boot" partition that GRUB needs.

n to create a new partition. Needs to be about 1MB. You can probably squeeze this in from sectors 34-2047. Use L or l to look up the code for "BIOS boot" (ef02).
Write the new partition table.

w
Reload the partition table. > partprobe /dev/sda

NetworkManager WiFi Power Saving

NetworkManager supports WiFi powersaving but the function is rather undocumented.

From the source code: wifi.powersave can have the following value:

NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value
NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1): don't touch existing setting
NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave

	# Brought to you by inhies
	#
	# This script creates TWRP compatible backups over usb using adb and magikz
	# By default it makes a folder in the standard TWRP date--time format (I think)
	# To restore these backups, place the folder in /sdcard/TWRP/BACKUPS/<serialnumber>/
