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 […]

Recovering the Firmware on a Supermicro BPN-SAS3-846EL1 Backplane

In a previous adventure I replaced an Adaptec HBA with a LSI SAS3 HBA, and the chassis drive bay LED’s stopped working. I suspect the LSI card does not play nice with the SGPIO sideband controller, and I decided to replace the chassis with one similar to my SC846 chassis, where the LSI card and […]

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 […]

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 […]

Razer Shoddy Support and Bad Software UX

This post is just me venting my frustration at Razer’s poor software user experience, and their shoddy support practices. I’m writing this after I just had to go and find a working mouse, so I could click a button on a dialog that had no keyboard navigation support. I’ve been using Razer keyboards and mice for […]

Circumventing ThinkPad’s WiFi Card Whitelisting

What started as a simple Mini PCI Express WiFi card swap on a ThinkPad T61 notebook, turned into deploying a custom BIOS in order to get the card to work. I love ThinkPad notebooks, they are workhorses that keep on going and going. I always keep my older models around for testing, and one of […]

UPS Battery Replacement Turns Into Unrecoverable Firmware Update

Two lessons learned; do not trust scheduled battery tests, and leave working firmware be!
