Unraid vs. Ubuntu SMB Performance

In my last round of testing I found that Unraid v6.8 SMB still underperforms compared to Windows Server 2019, but I was wondering if it is a Linux Samba problem, or an Unraid problem. I installed an Ubuntu Server 18.04.3 LTS VM on Unraid, bridged network, 16GB RAM, 128GB raw disk located on the BTRS […]

Unraid SMB Performance: v6.7.2 vs. v6.8.1

I previously wrote about the poor SMB performance I experienced in Unraid v6.7.2. Unraid v6.8 supposedly addressed SMB performance issues for concurrent read and write operations, and after waiting for the first bugfix release of v6.8, I re-tested using v6.8.1. In my last test I used a combination of batch files and copy and paste, […]

Unraid repeat parity errors on reboot

This post started with a quick experiment, but after hardware incompatibilities forced me to swap SSD drives, and subsequently losing a data volume, it turned into a much bigger effort. My two Unraid servers have been running nonstop without any issues for many months, last I looked the uptime on v6.7.2 was around 240 days. […]

Unraid in production, a bit rough around the edges, and terrible SMB performance

In my last two posts I described how I migrated from W2K16 and hardware RAID6 to Unraid. Now that I’ve had two Unraid servers in production for a while, I’ll describe some of the good and not so good I experienced. Running Docker on Unraid is magnitudes easier compared to getting Docker to work on Windows. Docker […]

Unraid and Robocopy Problems

In my last post I described how I converted one of my W2K16 servers to Unraid, and how I am preparing for conversion of the second server. As I’ve been copying all my data from W2K16 to Unraid, I discovered some interesting discrepancies between W2K16 SMB and Unraid SMB. I use robocopy to mirror files […]

Moving from W2K16 to Unraid

I have been happy with my server rack running my UniFi network equipment and two Windows Server 2016 (W2K16) instances. I use the servers for archiving my media collection and running Hyper-V for all sorts of home projects and work related experiments. But, time moves on, one can never have enough storage, and technology changes. So […]


Monoprice MP Voxel 3D Printer Setup

[Update] After using the printer for about two weeks, I returned it to Monoprice for a refund. I would suggest you stay away and look elsewhere, or wait until Monoprice addresses the serious issues; Polar Cloud disconnects while printing, IO timeout error breaks camera function, and the deal breaker is hangs during printing, with the touch […]


PurpleAir Sensor Installation

I’ve had a Ambient Weather WS-1400-IP weather station installed for some time, reporting to Weather Underground. During the fires of previous years, I considered getting an air quality monitor, but I could never find anything worth the installation effort. During this year’s fire season I saw several ads for PurpleAir, advertising that they collaborate with Weather […]

eNom Dynamic DNS Update Problems

Update: On 27 July 2018 eNom support notified me by email that the issue is resolved. I tested it, and all is back to normal with DNS-O-Matic. Sometime between 12 May 2018 and 24 May 2018 the eNom dynamic DNS update mechanism stopped working. I use the very convenient DNS-O-Matic dynamic DNS update service to […]

CrashPlan throws in the towel … for home users

Today CrashPlan, my current online backup provider, announced on Facebook of all places, that they threw in the towel, and will no longer provide service to home users. The backlash was heated, and I found the CEO’s video message on the blog post rather condescending. I’ve been a long time user of online backup providers, […]
