Today I learned I can completely abuse the ceph orchestrator to run all my (other) services in high availability mode. For many years my 30+ services all ran on a single host which goes down sometimes and which runs out of memory most of the day, even when I download more ram from the internet…

Thinking about creating an useless blog about all the things I do in my free time, starting with setting up a WordPress. But not setting it up like everyone else does, because I dislike running a mysql server in my infrastructure and therefore it’s patching time! Modifying WordPress so it can talk to my already…

My gluster FS is in danger! Since some version of glusterfs archlinuxarm started shipping binaries that resulted in UDF undefined instructions and crashes! I tried building glusterfs from source myself and also there I got these weird unsupported instructions placed by gcc. I started compiling debug builds and debug it with gdb and after hours…

Since I moved into my new flat all of my server infrastructure was in the small storage room located in my kitchen. The main problem is that the room was actually planed for storing food and drinks and all the devices produce so much heat that for example chocolate is melting! Also all the fans…

I have once again moved all of my server infrastructure to a new flat. But this will be my last flat moving ever. I bought this flat! It’s mine now. The storage room in the kitchen already has a very fitting IKEA Lackrack shaft: Preparing WiFi at the car One of my main problems is…

Remember my last post about my new homeserver, where I wondered if there will be enough air circulation for cooling the CPU? Well turns out, the CPU was running at around 80°C for weeks now and the fans are either stuck or are rotating but practically no air is moving through. The whole design of…

Amazon Prime membership includes 15GB cloud storage and unlimited photo storage. Since I already wanted to create a backup of my storage raid, I thought it would be nice to upload all my files encoded as pictures. I came up with a simple tool that converts files and folder structures into pictures, and allows you…

My initial raid array is starting to getting 100% filled up with movies, series, music, wikipedia and other wiki dumps, temporary torrents, a warez share and so on. Time to order new disks! Disks nowadays have much more capacity at a lower price so this upgrade consists mostly of 10TB disks. My homeserver enclosure and…

The new homeserver had to be moved into my new flat too but there was only limited space. Also it made a lot of noises with the fans, therefore it could not stay in our living room or my sleeping room. The flat had a small storage room, where most of its area was taken…
