This blog now runs on AlmaLinux OS 9

These are my configuration notes on using a PiKVM V4 Mini to connect to my four Ceph nodes via a cheap 4-port KVM switch.

My existing Enigma2 receiver, a Dreamdbox DM900 UHD, has been replaced by a Vu+ Duo4K SE.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

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

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.
