Sinopse:
Most books about file systems stay at the conceptual level — inodes, directories, allocation strategies. This one goes further: it documents a real, production-quality file system from the inside out. Written by the engineer who designed the Be File System, the book opens with the history and design constraints behind BFS before establishing a shared vocabulary of file system fundamentals that grounds the rest of the discussion. The core of the book is a guided tour through BFS's data structures — the superblock, i-nodes with their data streams, attribute system, B+tree-based directories, and the indexing layer that enables fast queries. Each chapter compares BFS's design choices against contemporaries like BSD FFS, Linux ext2, Macintosh HFS, SGI's XFS, and Windows NT's NTFS, giving the reader a comparative map of file system design tradeoffs rather than a single-system tutorial. Rare among technical books, this volume captures the reasoning behind real engineering decisions — why certain block sizes were chosen, how the disk layout evolved, and what the author would do differently. For anyone building or modifying a storage system, this book is less a reference and more a mentorship session with the person who built one from scratch.
