Moving from Unraid to Proxmox VE

I finally took the plunge and moved from from Unraid to Proxmox VE. I used to love Unraid, but at some point the easy to use web management UI and app store ecosystem simply lacked capabilities I needed for deployment automation and configuration tasks. Then there is the problem with the poor IO performance, that […]

Unraid User-Share vs. Disk-Share SMB Performance

This is yet another post on Unraid’s poor SMB performance, but I think I narrowed down the cause of the problem to the Unraid FUSE filesystem. I discovered this about 2 months ago, but with COVID-19 and no kids weekend sporting event duties, I have some time to post. In this round of testing I […]

Unraid vs. Ubuntu Bare Metal SMB Performance

In my last test I compared Unraid SMB performance with an Ubuntu VM running on Unraid, and Ubuntu outperformed Unraid. I was wondering if the VM disk image synthetically improved performance, maybe IO caching, so this time I tested Ubuntu on the same hardware that runs Unraid. I configured the system to boot from either […]

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 […]
