Make sure that the zpool devices command recommends the configurations preferred for zfs first and requires that the user add an extra option (e.g. -v) in order to discover less ideal device configurations. For example, ZFS prefers whole disks so if the disk contains partitions but none of them are used, then it can simply suggest the whole disk, but if some partitions are used it can list the unused partitions along with a warning that using partitions is a non-ideal configuration. If the devices are accessed via different paths/controllers, then that could be useful info for the user when selecting devices. I appreciate that Richard Elling would like to suggest the best combination out of 281,474,976,710,655 permutations, but at some point the choice is best left to the educated user. :-) The first challenge is to find the devices at all. Optimization is for later.
