My concern would be that it increases the impact of a corruption of the block that has been de-dup'd - in other words if the block that now represents the same data in lots of files gets trashed then all those files have corrupt data. This implies that you would want to keep around at least one other copy of that data to be resilient in the face of corruption (checksums will let you detect it, but not necessarily recover from it without duplicate copies). Given that ZFS prides itself on detecting errors it would be strange if they hadn't considered this in the implementation but I couldn't see any mention of it. cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file.
