Well, now that I've experienced some sort of disk failure on my NAS, I'm sort of annoyed that I did not set up any sort of notification system.
This is just a standard Ubuntu box sitting in the office. It doesn't have any sort of mail or cloud integration setup.
What would you recommend I use for alerting?
Anyway, I suspect a drive controller failure. It connects but the data is garbage. Can't even get SMART out of it.
@janusfox We have our machines set up so they can send outgoing mail with sendmail, which means stuff like cron email Just Works™.
We use opensmtpd, and it's pretty simple to set up opensmtpd to relay through your usual mail server _and log in to send stuff_, but you don't really have to do that if you're okay with your mails looking like spam to the mail server.
Anyway, if you've got that working, you could just have a cron job that prints some output and dies if things are horribly wrong, and then you should get mail about it.
@IceWolf I guess I just need to stop being lazy and install mail :)
Unless there's a USB plug-in klaxon, that'd be fine for me too!
@janusfox hehe failure siren! :3
But yeah, opensmtpd's my rec, it's WAY simpler and less annoying to set up than the likes of exim.
(If you're doing your own full-on mail server somewhere Dovecot is good for the IMAP side, as long as you chuck out all the config Debian ships with. All of it. Toss it in the garbage. You don't need it. They overcomplicated it to hell somehow, hah
but that doesn't matter for this, that's for wherever receives your "shit broke!!" emails. And is not a thing at all if you're sending it to an email account you already have.)
Anyway, if you install the opensmtpd debian package, it'll Provides: mail-transport-agent, automatically remove exim so you only have one, and everything will just use it (your system's mail server will provide a sendmail program that works with it and that's how stuff like cron or your own scripts can send mails)
opensmtpd's debian package USED to have a bug with TLS support which you had to install the one in backports to fix, but I thiiiink that was bookworm and not a concern now that trixie is the new normal.
@janusfox Once you install opensmtpd you'll have fully working local email, like, sending to other users on the same machine type stuff
I'm not sure if it'll attempt sending to other servers, but if it doesn't, the action/match stuff I mentioned in the config post should make it do that.
You can also receive mail from other computers by changing listen on localhost to listen on 0.0.0.0 and/or listen on ::. That match from any for domain "thunderjaw" action "local" bit may be needed as well so you can actually address it from elsewhere (change hostname appropriately of course).
