How full is your filesystem? Give us the output of "zfs list" You might be having a hardware problem, or maybe it's extremely full.
Also, if you have dedup enabled, on a 3TB filesystem, you surely want more RAM. I don't know if there's any rule of thumb you could follow, but offhand I'd say 16G or 32G. Numbers based on the vapor passing around the room I'm in right now. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
