As a Pro, you probably already have many scripts to help your day. This post is primarily about creating custom commands on Linux. Scripts can easily be turned into commands with options and help screens. #wol #script #tool #custom #commands #linux #WoL

All labs need a NAS for storage. Because we already have a ZFS file system, we do not need to run TrueNAS Core or Scale in a VM. We will use Samba with Cockpit as the GUI and run it in a CT. #nas #cockpit

The goal is to have one primary server (pve1) that is running my web server VM and a secondary server (pve2) that is in standby in the event that pve1 fails and then pve3 if pve1 and pve2 are out, and so on.
Proxmox
Making a Proxmox High Availability Virtual Machine cluster without a NAS or GLUSTER or CEPH. Some apps are extremely valuable and needed in our systems. They need to bee up 24/7. How to do it? And are we willing to bare the cost? That's all folks - now we have a 24/7 VM running.

What if your servers don't work, Where is your data? When is it up again?You need to create a solid back-up strategy and stick to using it. You can and should refined the strategy on a regular basis. Basic rule is the 3-2-1 rule

For running ZFS on RAID controllers we need the RAID-controller in HBA or IT-mode for RAID pass trough and a separate boot device, you can't usually boot from a HBA device.
Networking
We all need firewalls, and we can virtualize them or use HW versions It's best practice to use hardware firewalls. Netgate is a pfSense in a box with add on features. We will also add the QEMU Guest Agent to FreeBSD. #pfsense #virtual #router #firewall
Tools
Burn-in any HD or Server. When customer satisfaction is the key objective, you need to go the extra mail and make sure there are no breaks early due to bad HW or bad SW. Most bad HD failures happens early if they are to fail. The failing due to old age is easy to handle by monitoring.

Do you want to rice the logon screen of Proxmox? The idea is to show clearly the login as IP and FQDN and also all the colors and positions of the patch cables - this is not in stead of tagging cables its on top. #color #login #proxmox #update
Security
Monitoring Servers and VM's before tweaking VM's is one of the most fundamental tasks. Running thousands of pods on a server it's better to follow their performance. With tiny clusters it's vital to know whats going on. For this post we setup #Zabbix and #Grafana
Build
We all have devices we do not use 24/7 or even daily. For these devises it's convenient to perform a WoL when they are needed. They may run services not frequently needed or they are started when demand grows. #wol #wake-om-lan

I use Brew on my MacBook Pro but also on most of my Linux machines.
