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.
After installing RHEL 8, I started building a Ceph Nautilus cluster with my four TerraMaster F5-422 nodes.
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.
I reinstalled my TerraMaster F5-422 with CentOS Stream.
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.
It’s been about 2½ months since I started adding ODROID-HC2 nodes to my Ceph Luminous cluster.
This is a quick update on how it’s doing so far.
Just the steps needed to grow a cached LV.
I built a Ceph Luminous cluster containing seven ODROID-HC2 nodes. This cluster also contains some x86 VMs running on my hypervisor.
I use this cluster mainly as a Ceph playground.
For Ceph use I definitely did not want to mess about with serial console on the ODROID-HC2 (there are 7 nodes to install, there could be more). The instructions include getting rid of the need for serial console during first boot.
Added this to my server:
My braindump follows.
