Guide to Resetting a csync2 Cluster

Introduction

These are possible steps to reset a csync2 cluster that has been seriously fubared. This is an apocalyptic approach and should only be used when more surgical fixes (like correcting an individual conflict) aren't workable.

Use Cases

#Introduction If you're a php developer on ubuntu, there comes the time where you have to install/reinstall your system. I did it already a few times and i decided to write down the steps for a typical web developer stack with php. This is for a developer machine and not for a live environment!

	# If you open your Ressource monitoring under OSX, you'll see that the
	# Process "Spotify Helper" is eating between 20% and 30% of CPU constantly
	# It means that when you're on battery, it'll drain it faster.

	# To prevent the Spotify Helper (which are basically ads for spotify) from spawning process,
	# you should disable access to the app doing this (close Spotify first) :

	sudo chmod 000 "/Applications/Spotify.app/Contents/Frameworks/Spotify Helper EH.app"
	sudo chmod -N "/Applications/Spotify.app/Contents/Frameworks/Spotify Helper EH.app"

	#!/bin/bash
	#
	# Carries out a full mysqldump, calls percona-xtrabackup and then
	# copies the sql dump, the percona backup and your mysql bin logs
	# to S3 using s3cmd http://s3tools.org/s3cmd
	#
	# TODO: extract out the S3 backup stuff to make it optional, and so
	# other s3 programs can replace the s3cmd call.
	# TODO: the if [ $? == 0 ] alert blocks should be a function
	# TODO: make the if [ $? == 0 ] if [ $? != 0 ] more consistent - test
