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Let's start with the basics: the official guide by Ubuntu (https://ubuntu.com/server/docs/install/storage) is outdated/wrong.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 perfect Varnish configuration for WordPress, Joomla, Drupal & other (common) CMS based websites

Updated on December 15th, 2021

IMPORTANT: Read this before implementing one of the configuration files below (for either Varnish 3.x or 4.x+).

USE: Replace the contents of the main Varnish configuration file located in /etc/varnish/default.vcl (root server access required - obviously) with the contents of the configuration you'll use (depending on your Varnish version) from the 2 examples provided below.

IMPORTANT: The following setup assumes a 180 sec (3 minute) cache time for cacheable content that does not have the correct cache-control HTTP headers. You can safely increase this to 300 sec (or more) for less busier sites or drop it to 60 sec or even 30 sec for high traffic sites. It obviously depends on your use case.

	This is a tip for NCP Secure Entry macOS Client originally created in 2012,
	so it may not apply to recent versions...

	As of Jan 2024, NCP Secure Entry macOS Client is available here:
	https://www.ncp-e.com/en/service-resources/download-vpn-client
	https://software.ncp-e.com/NCP_Secure_Entry_Client/macOS/ (older releases)

	So, on to the issue...

	To disable the autostart of the NCP Secure Entry Mac Client GUI application on a Mac, just edit the /Library/LaunchAgents/com.ncp-e.ncpmon.plist file and set the value "RunAtLoad" to "false" (from "true"). It's faster to do it via command-line, like this:
