Why You Should Keep Your ZFS Pool Below 80% Capacity

Bymarek

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.

Why ashift Matters in ZFS: Getting It Right for Performance and Longevity
