  • Performance Tuning: Optimize recordsize, compression (zstd, lz4), and ashift values for databases, VMs, and media workloads.
  • Advanced Pool Operations: Manage special vdevs (metadata, small-file blocks), log (ZIL) and cache (L2ARC) devices, and understand their impact on real-world performance.
  • Data Integrity & Recovery: Perform deep scrub controls, device replacement, pool import/export recovery, and survive split-brain scenarios.
  • FreeBSD-Specific Features: Leverage boot environments (bectl), ZFS jail integration, and VNET networking with ZFS datasets.
  • Send/Receive Mastery: Create efficient incremental backups, resume interrupted streams, use raw encrypted sends, and replicate across networks with zfs send | ssh.
  • Encryption at Scale: Implement native ZFS encryption, key management, and rotation strategies without performance penalties.
  • Troubleshooting Toolkit: Diagnose corrupted metadata, fix pool errors with zdb, and recover from catastrophic failures.

: Understanding how ZFS allocates data (metaslabs) helps administrators diagnose performance degradation as a pool fills up. A common advanced recommendation is to maintain a "buffer" dataset with a reservation of 20–25% to prevent the pool from hitting the 80–90% capacity wall where performance tanks. The ARC and L2ARC : ZFS uses the Adaptive Replacement Cache (ARC) I can’t directly provide or link to a
