Oh damn it, I forgot the hashtags. Here:

Teste mal wieder Opencloud vs Owncloud auf dem Heimserver.

Ganz gut gefällt mir die Permalink-Sache von Opencloud:

Se anche tu come noi vuoi installare un server casalingo per i servizi più usati, passa venerdì 17 aprile dalle ore 21 presso la nostra sede di Solero e lo faremo insieme.

Looks like not only backups but also my obsession^Wpassion to write detailed entries to my "selfhosting journal" pays back. Any change, I made in my main home server, has a date and a detailed description of changes made. Also, the process of #NetBSD installation and service installation is documented too, alongside with documented list of running services, opened ports, cronjobs, etc.

At one bad day, my main server started to hangup at near 18:00 and at nea 08:00. There weren't any cron (or any another) jobs at this time. In the logs and monitoring the problems with mosquitto (MQTT server) were visible — somehow it eats at near 100% of CPU, then monit restart it, then things become working, then (after some time) the server hangs completely. Stopped it to see if the problem disappear. But the same problem happens with Prosody. At the end, the root cause of processes slowdown was my PostgreSQL. Investigation showed that write to my second ZFS disk (where the PostgreSQL DB lives) were extremely slowed, so ZFS panicked, crashed and crashes the kernel

At the same time, I hear a strange metal noises from server at near 08:00 too, so the destiny of second drive was specified.

The server restoration will take some time, but since anything were written in the log file, I'm able just to replay some actions and get all systems up as soon as possible

Reviewed a ZimaBoard 2. An incredible device, reminded me of a joy of the first Raspberry Pi

#homeserver #upgrades - replacement of CPU, motherboard, and OS disk this week. #Debian #trixie as the base. Aiming to do a bit of a cleanup as I go - ideally #containerising where possible, no VMs

So far;
* Unifi Network Server ❌ AP couldn't find it as a container. Installer script ✅
* #Wordpress ✅ some permissions fiddling required for compose
* #tvheadend ✅ some path fiddling for compose
* #zfs ✅ flawless detection and import
