Towards High Availability

Towards High Availability
In order to make my new 2 node Proxmox cluster highly available, I need shared storage for the VMs and a quorum in the cluster. Shared storage is available now as an NFS mount from the QNAP, but my goal is to retire the QNAP and move two TB disks into the first Proxmox node. There are a number of ways to do this, but I to chose to use GlusterFS volumes backed by ZFS.

Ansible and Terraform

Ansible and Terraform
Ansible is great for configuration management and does a good job of creating an environment that is (mostly) free of configuration drift. Using AWX, I’ve created a fair number of playbooks and roles which are executed regularly to keep things up to date and humming along. Terraform is a tool designed to enable Infrastructure-as-Code (IaC), meaning that the infrastructure is declaratively defined in code which can be managed by code ersioning tools such as git.

Cluster Storage

Cluster Storage
Now that the new host is up and functioning in the cluster, I need to start thinking about allocating the storage. The new host is showing the following storage: local local-lvm qnap-iso qnap-zfs The original Proxmox host has a local and local-vm storage as well, but I confirmed that these are not the same (should be obvious). These are local to that hosts and resides on the disk that was selected for installation of the Proxmox (500GB SSD).

Redundancy Redundancy

Redundancy Redundancy
This particular saga and the ones that will follow began with a simple sale on meh.com. A few months ago they had as their daily deal a motherboard for $35 USD so I snagged it not knowing what I would do with it. I began putting together a list of components I wanted to purchase with it, again not knowing exactly what I wanted to do it it. I knew I wanted to add some redundancy to my self-hosted/homelab setup which is built around a QNAP NAS and a single Proxmox hosts.

AWX Update

AWX Update
I recently updated one of my old posts about AWX because I discovered that the nfs-client storage provisioner which automatically creates persistent volumes using an existing NFS mount had stopped working. It not only stopped working, but it was deprecated and I had to find a new one that worked. In the process, I noticed that I never updated that post to include the updates to how AWX is installed and updated on Kubernetes.
