When I built my Ceph cluster in March 2020, I used old SATA HDDs I still had on the shelf. It was always clear that at some point these old consumables would die and need replacing. That time has come and I went with 3x 2TB SATA SSD OSD per node.

Since I mostly do LVM and sometimes btrfs, here’s a short braindump of my first ZFS on Linux rodeo.

These are my notes on how to upgrade the UEFI firmware on my QNAP TS-473.

Just a short write-up on the state of my TerraMaster F5-433 Ceph cluster now that it has been in use for about 3 years.

These are my notes on installing a brand new Framework Laptop DIY Edition (12th Gen Intel® Core™) from Batch 1 for myself.

These are my notes on installing a brand new Framework Laptop (Batch 9) for a nephew of mine. It is the model with 11th Gen Intel Core.

My existing Enigma2 receiver, a Dreamdbox DM900 UHD, has been replaced by a Vu+ Duo4K SE.

This is my braindump of the initial bringup.

This is my braindump on installing cephadm on CentOS Stream 9.

While I use a QNAP TS-473A for my tests plus 2 VMs, the below applies to any machine or VM running CentOS Stream 9 FWIW: My installation and initial configuration is described in the post QNAP TS-473A with CentOS Stream 9.

In happy distro hopping, I installed CentOS Stream 9 on my QNAP TS-473A.

These are my installation notes. They are similar to my RHEL8 notes and my Fedora Server notes.

I want a playground for Ceph’s cephadm that was introduced with Octopus and is also present in Pacific.

So I cleanly took my QNAP TS-473A out of my existing Ceph Nautilus cluster again (because I have enough combined capacity on my F5-422 nodes to be able to remove the OSDs in the TS-473A) and installed Fedora Server 35 plus cephadm from upstream.

I installed Fedora Server 35 on my QNAP TS-473A.

These are my installation notes. They are similar to my RHEL8 notes.

I got myself a Mountain keyboard, the Everest Max.

Since I had to boot Windows to set it up properly, here is my braindump on what I configured for my daily use with KDE Plasma on Fedora Linux.

I also noted my impressions, both positive and negative.
