Hardware changes to my Ceph Nautilus Cluster
I made some hardware changes to my Ceph Nautilus cluster.

While previously I used one SSD shared between the operating system and Ceph, I did want a clean setup where the OS and Ceph are on separate devices.
Four TerraMaster F5-422 with Ceph
After installing RHEL 8, I started building a Ceph Nautilus cluster with my four TerraMaster F5-422 nodes.

TerraMaster F5-422 with RHEL8
In further happy distro hopping (since Ansible makes this quite painless), I installed RHEL8 on my four TerraMaster F5-422.
UniFi Switch 16 XG fan modification
My new 16 port 10G switch was too loud for my taste. So I fit Noctua NF-A4x20 FLX fans instead.

After the modification, the switch looks the same on the outside.
Install four TerraMaster F5-422 with CentOS Stream
I received my 3 additional TerraMaster F5-422.
Time to install CentOS Stream in preparation for Ceph Luminous.
UniFi Switch 16 XG initial bringup
I bough a UniFi Switch 16 XG, Board Revision 13 (UniFi Software reports 13, while in the pic below I see 11, odd).
These are my notes on initial bringup.

TerraMaster F5-422 with Fedora 29
I installed Fedora 29 on my TerraMaster F5-422 for a quick Ceph test.
Obviously if you plan to use Fedora on this hardware for anything more than a quick test, use the latest version! Or try RHEL7 or CentOS Stream on it.
This is my braindump.
TerraMaster F5-422 with CentOS Stream
I reinstalled my TerraMaster F5-422 with CentOS Stream.
ThinkPad X270 RAM upgrade
Since 32 GiB SO-DIMMs are cheap at the moment, I decided to try an upgrade my ThinkPad X270 from it’s current 16 GiB RAM to 32.
RLY-8 Relay Controller, initial bringup
I added a RLY-8 to my home lab. It has 8 controllable relays and can be talked to via network.
These are my notes on initial bringup.
