Set up an automatic shutdown on your Linux or TrueNAS SCALE system using systemd timers to power off the machine 8 hours after boot. This approach helps automate processes and conserve energy. You can also manually interrupt or modify the shutdown timer whenever needed.
ZFS pools should ideally stay below 80% capacity to maintain performance and reliability. Exceeding this limit can lead to slow write speeds, increased fragmentation, inefficient space allocation, and prolonged scrub or resilver times. This article explains the technical reasons behind this recommendation and provides best practices for keeping your ZFS pool running efficiently.
A nearly full ZFS pool can cause performance issues, but there are solutions. This guide covers ways to free up space, including expanding the pool, enabling compression, deleting old snapshots, and offloading data. Learn step-by-step methods to reclaim storage and optimize TrueNAS performance while preventing future overfill issues.
With ZFS, ashift is your key to matching your drive’s stride. Choose the right size for your disk to keep writes quick and wear low. Set it too small, and it trips over itself; too big, it overpacks space. Get it spot-on when you begin, and enjoy a smooth, lasting storage setup.
