Resources
External references we trust for TrueNAS and ZFS — official docs, the OpenZFS project, and communities. Curated, not exhaustive.
Official Documentation
- TrueNAS SCALE Documentation
The authoritative source for SCALE features, storage tasks, and apps. Our first reference when a forum answer and the docs disagree.
#official - OpenZFS Documentation
The filesystem's own docs — ARC, recordsize, send/receive, and pool concepts explained at the source.
#official - TrueNAS Hardware Guide
Official hardware recommendations. The baseline we anchor home-build hardware advice to.
#reference
Reference & Deep Dives
- ZFS Capacity Calculator
Usable-capacity and overhead estimates for RAIDZ and mirror layouts before buying disks.
#planning - Jim Salter — ZFS articles (Ars Technica)
Clear, accurate ZFS explainers on pool design and performance from a well-regarded practitioner.
#reference - 45Drives ZFS resources
Practical pool-design and performance write-ups grounded in real large-array experience.
#reference
Communities
- TrueNAS Community Forums
The primary TrueNAS forum with heavy expert participation. Best for hardware vetting and pool-design review before you commit.
#community - r/truenas
Faster-moving Q&A. Good for SCALE app and version-specific issues; verify storage advice against the docs.
#community - r/zfs
Filesystem-level discussion — recordsize, special vdevs, send/receive edge cases beyond the TrueNAS UI.
