Uberblok: a museum of ZFS internals you can walk through
Eleven rooms on how ZFS keeps data safe, each starting from a real storage problem (silent corruption, the write hole, power lost mid-write) and answering it with an animated diagram and the OpenZFS code that does the work, pinned to one release: copy-on-write, transaction groups, RAID-Z, the ARC, the ZIL, send/receive. Plus a history wing with every fact sourced. MIT.
