Welp, my mastodon server is being wonky. It displayed the error page for a while, so I rebooted. The server failed to boot twice, then booted normally on the third attempt. I think there are two issues.

First, upgrading Ubuntu from 22.04 to 24.04 seems to have caused some sort of initramfs issue on the VPS.

Second, the Mastodon upgrade to v4.4.1 had a lot of problems and had to be restarted several times. That may have introduced some errors.

Finally got my Mastodon server upgraded to 4.4! 🎉

It looks like quote posts are working, too.

Running e-mail servers is always fun: as the time came to renew TLS certificate on one machine doing e-mail transmission (SMTP), came to know TLSA records are now supposed to be 3 1 1 (no more 3 0 1

There is an added benefit of 3 (DANE-EE) 1 (subject public key) 1 (SHA2-256 hash digest) - if you do not rotate your private key to issue TLS certificate, you don't need to update the TLSA record - signature can be squeezed from key and certificate is not necessary at that point. If you do rotate private keys, this enables you to pre-create DNS records even before certificate is issued (given that you already generated keys) - that is really nice

A sensible "3 1 1" + "3 1 1" key rotation approach

The domain name for this instance was just transferred away from squarespace to Namecheap. I think I have everything configured correctly, but we'll see. If I disappear, that's what happened. :P

And with that, I'm done with Squarespace for good.

So - dann mal Updaten auf Rocky 9.6 #mastodonadmin #serveradmin #wartung

Playing with email again. Since I have an email server and a mastodon server, I figured why not have an email address for my mastodon account. So I did. If you want to email me (and I don't know why you would) you can now send mail to my mastodon handle, omitting the leading @.

I might come to regret this. 😅

I just transferred the darkmoon.social domain away from Squarespace, so this instance may go down for a short time before I can get DNS set up again. If that happens, don't be alarmed. It'll be back up in all of its radiant darkness soon.

So one of our #servers decided to loose the home dir all the configs, volumes and docker-compose.yaml was living.

The running containers still hat the data... but it wasn't possible to #dockers cp em out... we could move some within the container and then docker cp them...

We still have no idea how this could happen... nobody was on the server and rm'ed it.

Took us a few hours now to restore everything.

Any of the #serveradmin around have a idea how this could happen?
