T10-DIF is a layer below ZFS. The two are complementary. The "fat bytes" are not exposed to ZFS. T10-DIF only detects some failure modes, mostly those in-transit over fabrics. It won’t detect corruption caused by overwrites, for example. To get true end-to-end detection you need checksums at the ends. ZFS provides this for file system level. Clever applications provide this for themselves. — richard ------------------------------------------- openzfs-developer Archives: https://www.listbox.com/member/archive/274414/=now RSS Feed: https://www.listbox.com/member/archive/rss/274414/28015062-cce53afa Modify Your Subscription: https://www.listbox.com/member/?member_id=28015062&id_secret=28015062-f966d51c Powered by Listbox: http://www.listbox.com
