Looking to create a Software RAID 1 setup for your 2-disk server on Ubuntu Server 20.04?

Let's start with the basics: the official guide by Ubuntu (https://ubuntu.com/server/docs/install/storage) is outdated/wrong. And as of March 2021 it's possible that there's a bug as well with how the bios_grub partitions are created when using multiple disks.

Now on to the solution:

• Select "Custom storage layout" when you reach the storage configuration step of the installer.
• If the disks have existing partitions, click on each disk under AVAILABLE DEVICES and then select REFORMAT. This will (temporarily) wipe out the partitions.

# The Zshell function will display the given message under-prompt (as a kind of notification).
# It has an optional delay first argument: "@sleep:<secnods with fractions>". If given, then
# the message will wait in background before showing for the specified time.
#
# Usage:
# deploy-message @msg "Hello world"
# deploy-message "Hello world"
# deploy-message @msg 1234 # I.e. the "@msg" is needed for number-only messages, otherwise optional
# deploy-message @sleep:5.5 "Hello world"

// Your browser must support ES6 async / await, Promises, and Template Strings for this to work.
// Do not remove the sleeps to make it faster. They are there to allow time for the Ajax calls that Canvas makes to process.
// If you are on a slow connection, you might need to increase the length of the sleep calls.
// I've also made it up to you to click the send button. Be sure to check that you pasted your invite url correctly.
// To run this:
//   * Go to the page on Canvas where you can see your messages from the class you want to send the invite to.
//   * Open your browser's console using F12 or by right clicking and then selecting "Inspect Element".
//   * Paste the below code into your console window and hit enter.
//   * Then enter add_students("INSERT_INVITE_URL_HERE"); into your console window and hit enter.
//   * The script will run and then all you have to do is proofread and hit send!

Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

• Example: https://gist.github.com/atenni/5604522/raw/
• Works even when you change the filename.

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]
