"Почему в ZFS нет необходимости в утилите fsck" Отправлено QuAzI, 10-Ноя-09 23:43
The blocks of a ZFS storage pool form a Merkle tree in which each block validates all of its children. Merkle trees have been proven to provide cryptographically-strong authentication for any component of the tree, and for the tree as a whole. ZFS employs 256-bit checksums for every block, and offers checksum functions ranging from the simple-and-fast fletcher2 (the default) to the slower-but-secure SHA-256. When using a cryptographic hash like SHA-256, the uberblock checksum provides a constantly up-to-date digital signature for the entire storage pool. Но всё равно можно SHA-256 включить, если уж ТАК заботиться о данных
