The current dedup code is said to be good with a truckload of memory and sufficient L2ARC, but at 4GB of RAM, it sucks quite badly. I've done some testing with 134 and dedup on a 12TB box, and even removing small datasets (<1TB) may take a long time. If this happens to you, and you get an (unexpected?) reboot, let ZFS spend hours (or days) mounting the filesystems, and it'll probably be ok after some time. Last time this happened to me, the box hung for some seven hours. I've heard of others talking about days.
