Uberblok

Uberblok is an interactive educational exhibit that explains how ZFS protects data through crashes, failing disks, and interrupted writes. Most rooms focus on a single concept, featuring an operable figure paired with direct excerpts from the OpenZFS source code. The project references OpenZFS release zfs-2.4.4 at a frozen commit, checking every code excerpt against the source repository. Topics covered include the uberblock, transaction groups, copy-on-write, checksums, vdevs, snapshots, and compression.
