How to expand disks from the command line in Ubuntu. This is something I do fairly frequently, and I can never remember the steps. So I decided to write them down. 1. Rescan for disk size changes echo 1 | sudo tee /sys/class/block/sda/device/rescan 2. Extend the physical partition (if needed) sudo growpart /dev/sda 3 3….
One of the nice things about the VMC Service is that you dont have to worry about a number of the traditional infrastructure services that you typically obsess over when your running your own infrastructure. One of those is Time…. A key requirement for any enterprise platform. Time VMC allows you to utilise the Amazon…
How to safety shutdown a vSAN Environment
I wanted to automate the publishing of my blog from the authoring side to the public side. These are some of the improvements I made. What I started with My previous setup, involved a locally hosted WordPress instance. This runs in my homelab in an Ubuntu VM. This I will refer to as the authoring…
I recently stumbled across Semaphore, which is essentially a frontend for managing DevOps tooling, including Ansible, Terraform, OpenTofu, and PowerShell. It’s easy to deploy in Docker, and I am slowly moving more of my homelab management over to it. Introduction This is a guide to show you how to get up and running easily with…

Update: Hoarder has now been renamed to Karakeep due to a trademark issue I’ve been on a mission recently to regain control of my data. I haven’t yet faced the humongous task of moving my main email from Gmail, but I have had some successes with other cloud services and a win is a win…….
Table of Contents Copy on Write Disk ID’s Trim I have run a number of systems utilising ZFS since the earliest days of my homelab using Nexenta all the way back in 2010. The image below is my lab at the time with an IBM Head unit that I think had 18GB of RAM 6x450GB…
Artificial intelligence is all the rage at the moment, It’s getting included in every product announcement from pretty much every vendor under the sun. Nvidia’s stock price has gone to the moon. So I thought I better get some knowledge and understand some of this. As it’s a huge field and I wasn’t exactly sure…
Yes, that’s a clickbait title. But technically it’s possible if I dropped all drive redundancy… I recently saw an advert for a server that was just too good to be true. It promised to bring a huge amount of storage and future options in a quite hard-to-believe 1U. The price it was on offer for…
My journey to superfast networking in my homelab
I recently decided to update some of my homelab hosts and I managed to do this at very little cost by offloading 2 of my Supermicro e200’s to fellow vExpert Paul. The below post describes what I bought why and how I have configured it. Table of Contents Node Choice Bill of Materials Rescue IPMI…

An Overview of vSAN ESA in VMC
Back in July I bought a new house and one of the best things about the property was that it was already in a City Fibre location. That meant I could take my Zen internet connection with me but ditch the ADSL (and Phone Line requirement). This gave me a much better connection in terms…

I recently helped my friend Dean Lewis @veducate with some hosting issues. As part of the testing of this he kindly gave me a login to his WordPress instance. He has been a pretty prolific blogger over the years pumping out an amazing amount of really good content. It also highlighted to me that I…
Yesterday I sat and passed the above exam. It had been on my todo list for a good number of years. With the current pause in the Broadcom VMware takeover deal. I had some downtime and decided to use one of the three exam vouchers VMware give me each year. This upgrades me to a…
A little while ago I decided to play with vGPU in my homelab. This was something I had dabbled with in the past but never really had the time or need to get working properly. The first thing that I needed was a GPU. I did have a Dell T20 with an iGPU built into…
There is a lot of uncertainty with VMware at the moment. This is all due to the pending acquisition by Broadcom. There are a lot of unknowns for the staff and customers about what the company will look like in the future. I certainly have some concerns mainly just with the unknown. However, VMware has…
Table of Contents Background ZFS Overview Read Cache (ARC and L2ARC) ZIL (ZFS Intent Log) Hardware Background I have just completed the move of all my production and media-based storage/services to TrueNAS Scale.

I am a huge fan of the Runecast product and luckily as a vExpert they give out NFR licences for my lab. One of the really cool features I wanted to mention today was the remediation script function. I have been playing with storage a lot in my lab recently as part of a wider…

Throughout that time Cloudflare has been improving there capabilities and approximately 2 years ago I decided to move this blog into their worker’s product. This meant…
I have been a VMware vExpert for many years and it has brought me many many benefits over the years. I don’t think it’s an understatement to say I probably wouldn’t have my current role within VMware without it. One of the best benefits has been access to a huge amount of licences for VMware…
For a while, I’ve been looking to update the networking at the core of my homelab. I have had some great results with the current setup utilising a number of DAC’s but there were a couple of things that were annoying me. Then MikroTik dropped the CRS504-4XQ-IN and if the price wasn’t horrendous then that…
I run a reasonably extensive homelab that is of course built around the VMware ecosystem. So with the release of vSphere 8 I was obviously going to upgrade however a few personal things blocked me from doing it until now. The vCenter upgrade was smooth however knowing that some of the hardware I am running…
Late to the party or not, I have been using containers in my lab more and more and that has led me to Portainer…. I use it for managing the docker containers on my Synology but it can also be used for managing lots of other things. In their own words “Portainer accelerates container adoption….
I recently spent 3 weeks in Ireland with my wife Wendy and our son Nate. This involves driving from the south coast of Dorset up to Scotland and then getting a ferry over to Belfast before travelling west to the Republic. While driving I got a slack notification that one of my SSD’s in my…
For a while now I have been running this site directly from Cloudflare utilising their excellent worker’s product. I did this originally as a learning exercise but due to the benefits It brought and the ease of use I decided to stick with it. The benefits are several fold: Crazy Web Performance (Typically full page…
Since moving to Dorset last year internet connectivity has been the bane of my existence. Currently, I have an ADSL connection provided by my old employer Zen and a 5G connection provided by Three. These are both plumbed into my WatchGuard Firewall with multi-wan configured. Most of the time the usability is ok but there…

The HP Z840 has changed its role to a permanent storage box running Truenas Scale. This is in addition to my Synology DS918+ TrueNas is the successor to FreeNas a very popular BSD based StorageOS and TrueNas scale is a fork of this based on Linux. The Synology has been an amazing piece of kit…
I have retired the WatchGuard Devices with the migration to PFSense running bare-metal in one of the Supermicro Nodes. I will likely virtualise this in the future. In terms of network/switching I have moved to an intermediate step here vMotion and Storage are running over DAC’s while VMware management and VM traffic is still over…
My lab is always undergoing change. Partially as I want to try new things or new ways of doing things. Sometimes because I break things (not always by accident) sometimes it’s a great way to learn…. I decided to list the workloads I am looking to run (some of these are already in place) Infrastucture…
Quite a few changes have happened in the lab recently. so I decided to do a multipart blog on the changes. The refresh was triggered by the purchase of a SuperMicro Server (2027TR-H71FRF) chassis with 4x X9DRT Nodes / Blades. This is known as a BigTwin configuration in SuperMicro parlance. This is something I was…
I have been making several changes (mainly cosmetic to this site over the last day or so) On most changes I have been doing an export and then uploading the site to Cloudflare using Wrangler. After a while I received an email from Cloudflare saying: Hi, You’re 50% of the way to reaching one of…
A while ago I started messing with Cloudflare Workers. I have now moved this site permanently over to them. This is partly related to some issues I have been having with internet access at home. Prior to this, the site ran from within my lab. This means the site is now super fast (hopefully :p)….
I have slowly morphed into an Apple fanboy over the last decade or so collecting a large number of devices ever since my first MacBook Air back in 2011. When you’re in the ecosystem additional devices just make sense….. I currently have: My Wife also has All in all a lot of apple devices need…

When you run a large enough Infrastructure failure is inevitable. How you handle that can be a big differentiator. With VMware Cloud on AWS, the hosts are monitored 24×7 by VMware/AWS Support all as part of the service. If you pay for X number of hosts you should have X. That includes during maintenance and…
I recently sat (and passed the VMware HCI Master Specialist exam (5V0-21.20). I won’t go into any details of the contents but I will comment that I felt the questions were fair and that there wasn’t anything in it to trip you up. The required knowledge was certainly wider than the vSAN specialist exam. This…
VMware Cloud on AWS (VMC) has introduced a new host to its lineup the “i3en”. This is based on the i3en.metal AWS instance. The specifications are certainly impressive packing in 96 logical cores, 768GiB RAM, and approximately 45.84 TiB of NVMe raw storage capacity per host. It’s certainly a monster with a 266% uplift in…
I saw a tweet a couple of weeks ago mentioning that Nutanix were offering a free go at the Nutanix Certified Professional exam. They are also offering free on-demand training to go with it. In my current role, I haven’t used Nutanix however I have good experience using it as the storage platform with vSphere…
As everyone knows by now the world has changed possibly forever. Due to Covid19 working from home has become the new normal. We are lucky in the IT world that this has been fairly straightforward for most of us. We are privileged in that it’s possible for us to continue indefinitely. Organisations still need to…
As previously mentioned I have been working a lot with VMware Cloud on AWS and one of the questions that often crops up is around an approach to monitoring. This is an interesting topic as VMC is technically “as a service” therefore the monitoring approach is a bit different. Technically AWS and VMware’s SRE teams…

Lab Storage Update. Since starting my new role with Xtravirt my Homelab has gone through several fairly significant changes. At the moment it’s very much focused on the VMware stack and one of the things I needed was some more storage and especially some more storage performance. With that in mind, I purchased a new Synology…
I have seen a few posts online recently about the tools and technology people use on a day to day basis. A few components that I have no one seems to have mentioned yet. So I thought it was probably a good idea to share my list. I will probably do a separate list of…

I ran a Nutanix CE server at home for a little while when it first came out. However, due to the fairly high requirements, it didn’t make sense to me to continue running it at home. This was compounded by the fact that I have many clusters to play with at work. These all run my…
