ZFS COMMANDS TO MONITOR DISK HEALTH HOW TO

Therefore, taking this approach makes the ZFS file system always consistent, even during a crash event. The entire operation uses a copy-on-write (COW) mechanism to help to guarantee the atomicity of the process. Thus, by using the uberblock ring concept, both are written to disk or neither is written. ZFS provides transactional behavior that enforces data and metadata integrity by using a powerful 256-bit checksum that provides a big advantage: data and metadata are written together (but not exactly at the same time) by using the 'uberblock ring' concept, which represents a round that is completed when both data and metadata are written.
