Instructions to create an LVM cache for root in Fedora

LVM cache in Fedora

From the man-pages: "The cache logical volume type uses a small and fast LV to improve the performance of a large and slow LV. It does this by storing the frequently used blocks on the faster LV. LVM refers to the small fast LV as a cache pool LV. The large slow LV is called the origin LV. Due to requirements from dm-cache (the kernel driver), LVM further splits the cache pool LV into two devices - the cache data LV and cache metadata LV. The cache data LV is where copies of data blocks are kept from the origin LV to increase speed. The cache metadata LV holds the accounting information that specifies where data blocks are stored (e.g. on the origin LV or on the cache data LV). Users should be familiar with these LVs if they wish to create the best and most robust cached logical volumes. All of these associated LVs must be in the same VG."

Assuming LVM is already setup in HDD (e.g. from anaconda) and SSD is untouched.

I use this script to backup my QEMU/KVM/libVirt virtual machines. The script requires KVM 2.1+ since it uses the live blockcommit mode. This means the data in the snapshot disk is rolled back into the original instead of the other way around. Script does NOT handle spaces in paths.
#!/bin/bash
#
BACKUPDEST="$1"
DOMAIN="$2"
MAXBACKUPS="$3"
if [ -z "$BACKUPDEST" -o -z "$DOMAIN" ]; then
echo "Usage: ./vm-backup <backup-folder> <domain> [max-backups]"
exit 1

A small script for controlling mpv via the JSON IPC. Intended to resemble playerctl.
#!/usr/bin/env bash
# This script requires:
# - that the directory $HOME/.mpv exist
# - that the program socat be installed
# - that you start mpv with the unix socket feature pointing at that directory
# I recommend an alias in your .bashrc or equivalent file:
# alias mpv="mpv --input-unix-socket=$HOME/.mpv/socket"
socket="$HOME/.mpv/socket"

Setup SSH keys for use with GitHub/GitLab/BitBucket etc

Create a new repository, or reuse an existing one.

Generate a new SSH key:

ssh-keygen -t rsa -C "your_email@example.com"

Copy the contents of the file ~/.ssh/id_rsa.pub to your SSH keys in your GitHub account settings (https://github.com/settings/keys).

Test SSH key:
