E-Mail notification in case of a drive failure (Ubuntu)

[Senzelian]

I have a Plex server running on Ubuntu 22.04 LTS and I'd like to receive an e-mail in case a hard drive would fail.

How would I go about doing this? 

 

I saw some guides for "mdadm", but was very confused when none of the guides seem to mention how to set up the necessary SMTP account for sending out emails. They only seem to describe how to set up the target email address.

If you have the ability to trigger a script on drive failure, then you should be able to write a script that uses e.g. mailx to send an email somewhere using authenticated SMTP: https://bgstack15.wordpress.com/2017/08/05/send-authenticated-gmail-from-cli-with-mailx/

They assume you have mail already set up.

If your server can't mail out by itself, you could relay to an external mail server.

 

Take a peek here for what I think is a good tip in the replies:

Example of a bash script to check smart status:

You should be able to consolidate that into something that fits your purpose.
