Hi Zeus, you can use dd, if the target stick has the same (or larger) size but you have to export the pool first. Other option is to create a ZFS mirror of both sticks, resilver it and then use the "zpool split" subcommand. If you do it this way, the new pool will require a different name, so you have to rename it by reimporting it under the original name (after exporting the original pool). A third working but not that nice way is to create a ZFS mirror, resilver it and export it. Then you may physically separate the devices and load the second one on the other system. Remember, it will always be loaded as a mirror with one missing device, so you have to detach the missing device later.
