This Skill helps you run reliable, safe TrueNAS SCALE/CORE operations—setting up shares, managing datasets, fixing permissions, scheduling snapshots/scrubs, and designing correct replication—while avoiding common ZFS misconfigurations that lead to data loss or broken access.
Use case: You need an SMB share that’s accessible from your network and writable by Docker containers, while also ensuring monthly scrubs, automated snapshots, and offsite replication are correctly configured.
Ask your AI to produce a TrueNAS dataset + snapshot + scrub + SSH replication plan for your SMB/NFS share, including the correct record size and container PUID/PGID permission strategy, based on your current pool health and the intended workload type.
High-intent search queries and answers about installing and using this skill.
TrueNAS ZFS dataset permissions for Docker containers require matching ACL/POSIX ownership to the container's PUID/PGID values, ensuring SMB shares remain accessible across the network while allowing seamless container read and write operations.
ZFS record size selection depends on your specific workload type, but you must avoid changing record sizes after data has been written to the dataset to prevent performance degradation and maintain data integrity.
ZFS send and recv replication over SSH for TrueNAS offsite backups requires configuring SSH connectivity between local and remote systems, designing encryption-aware replication tasks, and verifying snapshot transfers to ensure data integrity.
You should avoid enabling ZFS deduplication on TrueNAS pools using mechanical disks, as it heavily impacts performance and can lead to severe bottlenecks during read and write operations on non-NVMe storage.
Scheduling ZFS scrubs and automated snapshots in TrueNAS involves configuring regular scrub tasks to detect pool corruption and setting snapshot policies to capture dataset states, ensuring you can recover data from unintended loss.
Migrating from TrueNAS CORE to SCALE requires following a safe migration path to preserve existing ZFS dataset layouts and SMB/NFS share configurations, ensuring container-compatible permissions and access controls remain intact.
