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.

How I switched from mdadm to btrfs

After reading [this Ars Technica article][1], I decided that I wanted to start using btrfs on my home fileserver. It had been running for a few years with an mdadm raid-10 array, formatted with ext4, holding about 3.4 TB of data. I figured I would take advantage of some of the special capabilities of btrfs to perform the conversion in place. After some research, I formed my basic plan.

• backup data to external drives
• remove two of the drives from the mdadm raid-10
• configure those two drive with a btrfs raid-0 filesystem
• copy the data from the degraded mdadm raid-10 to the new btrfs raid-0
• completely deactivate the mdadm raid-10

JavaScript to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in JavaScript and Rust so that programmers most comfortable with JavaScript can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?

Variables

Installing Kerberos on Redhat 7

This installation is going to require 2 servers one acts as kerberos KDC server and the other machine is going to be client. Lets assume the FQDN's are (here cw.com is the domain name, make a note of the domain name here):

• Kerberos KDC Server: kdc.cw.com
• Kerberos Client: kclient.cw.com

Important: Make sure that both systems have their hostnames properly set and both systems have the hostnames and IP addresses of both systems in
