Roon Core on a NAS???

After commenting on several posts regarding running Roon Core in a TrueNAS BHYVE VM in the Roon Community Forums, I get the occasional request for help troubleshooting a colicky Roon Core installation. Please stick to Roon recommended configurations unless you are a computer systems professional. Installation of Roon on Linux hardware or in a storage server virtual machine requires familiarity with the host operating system, host OS package manager, host OS virtual machine manager, creation of guest environments, and installation of Linux and applications in the guest environment. This is a lot to learn for non-professionals.

For DIY Readers

Most DIY-minded readers would be happiest running Roon Core on a Mac Mini backed up by a TrueNAS SOHO file server configuration. The Mac Mini can perform media management. The Mac Mini can back up your external media to TrueNAS using Time Machine. iX Systems ensures that TrueNAS is easily configured as a Time Machine storage server supporting encryption at rest and encryption in transit.

For My Other Readers

Those not members of the DIY gang would be happiest using Roon Nucleus as their Roon Core. Roon Labs has designed Nucleus to be a no fuss appliance that keeps OS and Roon Controller up to date software wise. Roon Nucleus is audibly and electrically quiet as a result of its fanless design and custom power supply that replaces the laptop switching power supply used with similar systems.

After the break, we’ll look at the alternatives in more detail.

Festus Joins Dismal Manor Gang

I tired of the Dyson’s canister’s small bin (3 empties per cleaning), propensity to clog, and dust belching manors. So I did what I was tempted to do years ago. I ordered a Festool Extractor CT15E for use as a domestic vacuum. How’s that working out? Pretty well actually. More after the break.

Maggie Extends Her Dismal Manor Visit

A few days ago, I watched a young gentleman comment on selection of amplification for Magnepan Magneplanar Loudspeakers. He is a Maggie fan and has owned a number of Maggies and paired them with various new and used amplifiers. Although a good presenter, he managed not to offer much insight into Magneplanar speaker behavior. So, I’ll tell you what I’ve learned in the 5 months or so this pair has been here.

TrueNAS Encryption

TrueNAS 12 based on FreeBSD 12 now offers ZFS native filesystem encryption. A pool or any part of a pool may be encrypted. This is particularly useful when an application requires encryption of data at rest. One common use case is the encryption of Apple Time Machine backups at rest. In this article, I will explain how to configure an encrypted filesystem for use by Time Machine.

TrueNAS 12 Replication

TrueNAS is built on FreeBSD and the ZFS copy on write filesystem originally developed at Sun Microsystems for use in petabyte scale systems, possibly with cluster filesystem support layered on top. Today among hobbyists and system integrators, TrueNAS finds use in small scale file servers in home and office environments.

Purchased storage systems from iX Systems (are you a Dune fan?) make ZFS and TrueNAS FreeBSD accessible to small organizations needing reliable shared file storage. It is ideal for small medical offices and graphic and creative arts professionals needing working and archival storage. The TrueNAS SOHO systems are price competitive with home brew from new systems as a result of volume purchase of components. TrueNAS carefully tailors the FreeBSD component selection and system configuration for the storage appliance mission. In most installations, TrueNAS functions solely in the storage role. In home and small office installations, it may also provide some application support. Here at Dismal Manor, our TrueNAS system also runs our Roon Audio service instance in a VM.

Roon with TrueNAS

Roon and TrueNAS 12 coexist nicely. Here at Dismal Manor, I have a TrueNAS 12.0 server that has two jobs, to serve music and to provide Time Machine storage for MacOS Big Sur. In this episode, I will describe the TrueNAS configuration used here at Dismal Manor. This arrangement is not particularly elegant as I was learning to manage TrueNAS as it was evolving from FreeNAS 9 to the current TrueNAS 12 core.

Thoughts on Schiit Audio

We sure have a lot of Schiit Audio about Dismal Manor. How did it happen? More importantly, why did it happen? The Schiit Audio product line, especially the headphone amplifiers have a similar sound as co-founders Jason Stoddard and Mike Moffat are largely responsible for the sound of a product. Although they like different sorts of music, both have a strong preference for a neutral voice, focused image, and a good bit of depth in their DACS, preamps, headphone amps, and speaker amps.

Jason has written extensively

https://www.head-fi.org/threads/schiit-happened-the-story-of-the-worlds-most-improbable-start-up.701900/

about his odyssey as a practicing audio design engineer, Schiit Audio’s design philosophy and business principles, and about the development of individual products. Schiit began business in the desktop audio space offering DACS and headphone amplifiers. Schiit then expanded into the main system market offering first an integrated amplifier, then preamps and, in 2017 or so, its first speaker amp. In 2019 and 2020 Schiit entered the vinyl space with a Mike Moffatt phono preamp that is wizard and a turntable for the ages.

Freya+ A Week Later

Freya+ has been here a week, has shown a movie or two and played quite a few records. This post recounts our experiences to date. Associated equipment are Schiit Modius, Gumby Multibit, and Vidar. Most media was Qobuz or Roon disc library based. I also talk about the new speaker placement I settled on.

Freya+ Comes to Camp

So now, the Dismal HiFi is a whole pile of Schiit with Vidar, Gumby multibit, Modius, and Freya+ in the system. It just sort of happened. Gumby on faith, then Magni and Modi in the study, Modius for TV audio in the lounge, Vidar for muscle when Ampzilla finally got toasty, and then Freya+ because Aunt Nancy Pelosi wanted me to stimulate the California economy. Purchases of Schiit gear help lots of ordinary people in addition to co-founders Jason and Mike.

Anyway, kudos to Jason for design and a terrier’s attention to detail, Mike and Dave and others who helped with design review and critical listening. And kudos to the counter-intelligence who put things together, pack and ship. It is always a pleasure to unpack a Schiit order because you know your it will be picked and packed correctly and the kit will work. Thanks folks.

A Little Raspberry Pi

I’ve been watching to Mandolin.Com live stream shows during the live music quarantine. My old practice was to AirPlay from an iPad to the lounge AppleTV. I got tired of this (WiFi stalls next to the airport) and decided to eliminate the stuff in the middle. Raspberry Pi Foundation came to the rescue.
