I added a QNAP TS-473 to my Red Hat Ceph Storage 4 (Nautilus) cluster.

This is my braindump.

I installed Red Hat Enterprise Linux 8 on my QNAP TS-473A.

These are my installation notes.

I purchased a QNAP TS-473. This comes with a AMD Ryzen Embedded V1500B 4-core/8-thread @ 2.2 GHz CPU.

These are my notes from initial bringup.

Janine bought herself two ASUS PN51, specifically the PN51-E1 model.

As previously described, I had replaced the fans in my UniFi US-16-XG, but until today I had not put in any low noise adapters (LNA).

That changed today, I added two LNA NA-RC10 (8.3 m³/h, 12.2 dbA) because the switch is still the most noisy piece of equipment in my homelab.

My Jolla Tablet seems to have died.

:-(

While for my virtualisation needs I am firmly in the Red Hat camp, an article in ix 9/2021 piqued my interest.

Since I was on a week of ‘staycation’ and the T7910 was not in use, I decided to test Proxmox VE 7.0 on a Dell Precision T7910 tying in my existing Ceph Nautilus storage for both RBD and CephFS use.

After upgrading the memory of my ASUS PN50 to 64 Gib, it was installed as an OpenShift Container Platform (OCP4) worker node.

This is my braindump of using virt-resize to migrate 3 OpenShift 4 master VMs’ qcow2 disk files, on a CentOS 7 hypervisor, from 70G each in one libvirt storage pool to 150G each in another pool.

Because my ASUS PN50 running MythTV was initially installed with F32 and I routinely DNF System Upgrade, it has been running F34 for a while now.

The main reason for this post is that the infrared receiver and watchdog seem to finally work.

These are my notes on installing a second hand Lenovo ThinkPad T480 (20L6) for a relative of mine.

This is my braindump on setting up:

• Raspbian GNU/Linux 11 (bullseye) on a Raspberry Pi 4 Model B
• housed in an Argon ONE case with power button and fan
• USB audio to a Teufel Cinebar One+
• Playing music via DLNA
