OpenZFS is often discussed in terms of features such as checksumming, copy-on-write, and snapshots. But the real story lies in the on-disk structures that make these capabilities possible. This talk takes a bottom-up journey through OpenZFS, from block pointers and dnodes through object sets, uberblocks, and vdev labels, exploring how these implementation details translate into data integrity, consistency, recoverability, and operational simplicity.
