Backing up unRAID to Stabelebit Drivepool using Kopia

Since I retired Mediaserver 8.1 and  Mediaserver 8.2 in favour of Mediaserver 8.3, I've had a spacious ThermalTake Core X9 case and AMD FX-8320 based motherboard sitting around. I also have a selection of hard drives ranging from 500GB to 4TB that are retired from my main unRAID system. I'd been hankering to turn all of this into a backup server and, in fact, had made a few attempts that never really made it past proof of concept. It was time to attack the project seriously....

Building an UnRaid Home Server for Media Storage and Automation

Are you looking to create a versatile and efficient home server that can handle your media storage needs while seamlessly integrating with your home automation system? If so, building an unRaid home server might be the solution you've been searching for. In this post, we'll explore the benefits of unRaid and provide practical advice on building your own home server for media storage and automation.

I've been using unRaid for home storage and automation for about 10 years now, and have been blogging about it here for almost as long. A lot of my posts are quite specific, so I thought I'd try a high level guide for those starting out. Let me know what you think, or if there are other specific topics you'd like to see covered.

Mapping additional and network drives inside an unRaid Windows VM

On the unRaid forums recently, I was responding to a user who was asking why his VM gcow2 image did not shrink when files are removed (thread here). I advised that auto-shrink is not standard behaviour, and in the discussion, it became clear that the use case was security camera footage. The user figured out that perhaps saving video files to a network share would be better than to the VM boot / system drive, and I mentioned that I do this with my BlueIris setup. I promised a quick guide, so here it is....

X-Case X465E First Impressions

My current server lives in a ThermalTake Core X9 case. While I like it a lot, and its generous dimensions have allowed me add lots of PCIe cards,  its proving itself to be somewhat toasty, especially for drives which are often reporting high temperatures.

The system lives in an attic space that heats up over summer which does not help with thermals. The unwieldy size and din generated by multiple fans makes moving location somewhat tricky.

For the past few weeks, I've been toying with the idea of slimming down and going for a rack mount setup. In this mindset, I came across the X-Case X456E from xcase.co.uk. This is touted as a 12 slot 4U rackmount server case. This piqued my interest as the extra PCI slot capacity is something that I'd modded in to my current case, and here it was, out of the box.

This trick is achieved by moving the PSU to the front of the case. The compromise here is a reduction in hard drive capacity (8x 3.5"). However, happy to live with this and use a second chassis for any additional drives, I went ahead and bought one.

There were a few obvious improvements to be made which I documented in this first impressions video;

MediaServer 8.3 - Bifurcation Edition

Some hardware updates, some minor mods and lots of cabling later, I've managed to get my unRAID server hosting eleven (13?) usable PCIe/PCI expansion cards which I'm using to manage storage devices and populate VMs with passthrough GPU, USB and Utility adapters.

All with 2x slots to spare on my 5x slot mainboard.

Here's how...

Solved - Av Access USB prevents system boot

In a previous post, I'd detailed my setup of using a  4KEX100-KVM  to extend an unRaid VM to a very remote screen over ethernet.

This has worked out great, with one exception. With the Av Access transmitter USB plugged in to my server, the system would not post. It was necessary for me to unplug the USB, wait for post and unRaid to start booting, then plug the USB back in.

This was a chore, especially as my server sits in my attic and can be a pain to access.

I was living with the issue as thankfully I don't need to reboot too often, but in researching something else recently, I came across a known issue with some older USB devices. It turns out that some USB devices feed +5V back to the host adapter. This can result in some motherboards failing to post - my symptoms exactly.

The extreme solution is to sever the +5V wire in the USB cable (!) but before going that far, I decided to try placing a USB hub inline between the USB host adapter and the transmitter unit. Hey Presto! I can now boot and reboot without issue.

All hail the interweb.

MediaServer 8.2

It’s been over 5 years since I built MediaServer8, an unRaid based system that looks after not only storage duties, but also hosts my main workstation, manages whole-house audio systems, whole house LiveTV and PVR, home automation and a bunch of other stuff through dockers, VMs and plugins.

The AMD FX8320 based system has been rock solid in all of that time. Indeed, the only problem I’ve ever had occurred in the past week when my dual 1TB spinners assigned to a cache pool started showing millions of unrecoverable BTRFS errors. Fortunately, I rescued my appdata and domains folders in time. My docker image was not so lucky :-(

A few months ago, the itch emerged and, try as I might, I found it difficult to resist the urge to scratch. There was nothing wrong with the system per se, but with ‘only’ 8 cores and 32GB RAM, it was a bit restrictive in the number of VMs I could run simultaneously, and no real scope for growth. I had a particular hankering to virtualise the dual boot Hackintosh the family use daily, as well as a few other utility systems. Threadripper was calling. Here’s how I answered....

Routing VMs anywhere

I'll start my saying that these things are freaking amazing!

I've been running a few VMs on my unRaid box for a while now. Specifically my main workstation (Win10 /OSX switchable), as well as some utility boxes.

One of the challenges has been physical location and signal transfer - my unRaid server resides in my attic and any VMs that required an interface (display & USB), would need to be located within the reach of a HDMI run.

This ruled out virtualising some systems, including a Win 10 / OSX dual boot hackintosh that's the main system the family uses. It's miles away from the server with no hope of running cables.

I'd toyed with HDMI over ethernet before, with little success. Recently, however, I came across the Av Access range of products...

The Grand Plan

Welcome to Mediaserver8, a place where I document my adventures in home automation and media serving - mostly for my own reference and future sanity!

I'm going to keep this post on top and maintain the overview schematic at Gliffy to offer an introduction to my HA system as it evolves. (Here's a direct link to a scalable version of this diagram).

Read on for a detailed breakdown of this setup...

Naked Redirects

To facilitate external service access to Mediaserver8 which is on a dynamic IP, I set up a domain with dns redirect via duckdns. While this works fine for ww.mydomain.online, plain old mydomain.online was still defaulting to a GoDaddy page as the A record needs an IP address.

Recently I stumbled on this post which outlines a solution using wwwizer.com. Simply point the domain A record to their service IP address and they will 301 redirect it to whatever the www CNAME record is set to - in my case duckdns.org. Now both www.mydomain.online AND mydomain.online reach my server. Magic. And free!

The only caveat is that wwwizer don't do https, http only. I can live with that.

The Pursuit of Quietness

Since MediaServer8 now lives in my Home Theatre, I'd like to make it as quiet as possible. The current set-up employs 3x Silverstone 120mm fans working as intakes in the base underneath the hard drive cage, (these came with the SST-GD07B Case and are very quiet),  as well as 2x Noctua NF-S12A PWM Case Fans  working as intakes on the side. These are all controlled from a NZXT Sentry Mix 2 Fan Controller.

This is reasonably quiet, but I think it could be better. I ordered some Noctua NF-R8 redux-1200 by mistake, thinking they were 120mm when in fact they were 80mm so I had to get a few more Noctua NF-S12B redux-700 as well.

 I'm very impressed with these Redux line units. Even though they're bare bones (with just the fan and 4x fan screws in the box), the packaging still has a premium feel (with not a bit of clear plastic in sight). And are they quiet!
