It's been a while, let's go! Any major fuckups lately or smooth sailing?

I had to change the local DNS setup yesterday. I finally installed my wife Linux Mint and wanted to set her up for Vaultwarden real quick which became an hour long debug session since apparently CNAME entries for hostnames don't work as I thought. Never came up the recent year as all my machines took it, but resolved refused to and so I eventually deleted the entries in the Pihole and created them as A records pointing to the VM with the reverse proxy, hoping I won't need to change the IP anytime soon. It's always DNS!

In other news I think I moved all my local dockered services to forgejo+komodo now and applying updates by merging renovate MRs still feels super smooth. I just updated my calibre web automated with a single click. Only exception is home assistant where I have yet to find a good split in what to throw in a docker volume and what to check in git and bindmount.

I had a weird issue with a server SSD.

6 months ahead of scheduled swap, it didn't die, it just started reading and writing really sluggishly, making the whole server behave really weird. Disk smart statistics looked healthy and disk self tests passed with flying colors. Anyway, had to swap it early and do a re-install of the OS.

The rest of my cluster temporarily took over running some pods and only saw downtime for a few pods that were dependent on some disks in the failing server.

I guess the incident has restarted my interest in distributed storage.

Blergh, how did you pinpoint it?

[–] dotslashme@infosec.pub 2 points 5 months ago

More luck than anything really. It was probably because it had 6 months left and the fact that reading and writing felt slow. Everything else behaved normally and buying a new disk was an educated guess that turned out to be the correct choice.
