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.
Igor Ostapenko is a contributor to FreeBSD and OpenZFS with extensive software development experience across various domains, including systems for manipulating and testing navigation devices, enterprise solutions for optimizing business processes, reverse-engineering, and B2B/B2C startups.
