The ZFS filesystem
summary
Hands‑on ZFS on FreeBSD: creates pools using mdconfig memory devices, runs zpool and zfs commands to make pools and datasets, shows snapshots and boot environments, and inspects pools with zpool status and iostat. Highlights: 400GB→27GB compression on real data, constant‑time zpool destroy and pool expansion, and self‑healing repaired 196MB from a corrupt mirror. Demonstrations use VirtualBox/VMware or local FreeBSD installs and succeed with live fixes and fast rollback.
