Hi, I have tried what dedup does on a test dataset that I have filled with 372 GB of partly redundant data. I have used snv_133. All in all, it was successful. The net data volume was only 120 GB. Destruction of the dataset finally took a while, but without any compromise of anything else.

Hi all, Now that the Fishworks 2010.Q1 release seems to get deduplication, does anyone know if bugid: 6924824 (destroying a dedup-enabled dataset bricks system) is still valid, it has not been fixed in in onnv and it is not mentioned in the release notes. This is one of the bugs i've been
