[LUNA] FreeBSD ZFS 'RAID0' setup ....

[Jared Wilkinson]

Ok, now that I'm awake, I can actually answer better! :)

Yes, you can do that. On the last command in the first section, just leave
out the 'mirror' portion of the command and list all the partitions. That
will create one big zfs pool called zroot with 4TB of space. Or you can
just start with the first partition, load your OS and after it's running
you can do a 'zpool add zroot' and list all the disks to add to it, growing
the size of the volume.
