I am trying to understand if zfs checksums apply at a file or a block level. We know that zfs provides end to end checksum integrity, and I assumed that when I write a file to a zfs filesystem, the checksum was calculated at a file level, as opposed to say, a block level.
ZFS checksums are done at the block level. End to end checksum integrity means that when the actual data reaches the application from the platter, we can guarantee to a very high certainty that the data is uncorrupted. Either a block level checksum or a file level checksum will suffice. -- Regards, Jeremy _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
