Uberblok is presented by its maker as: "an interactive museum of ZFS internals". It was shared on Show HN in 2026, where it received 82 upvotes on Hacker News.
An interactive museum of ZFS, room by room: each idea of the OpenZFS source made visible, with the real code. Uberblok Storage has always had the same enemies: disks that lie, writes cut short, a crash in the middle of an update.
ZFS answers them with a handful of ideas. This museum shows them one room at a time, from the code that implements them.
