You didn't show us how your friends pool is set up. With RAIDZ1, the capacity of one of the devices in the pool is used for redundancy, with RAIDZ2 it's two disks worth. So three 2TB disks with RAIDZ1 gives you 4TB net capacity. If you don't care about redundancy, use a simple concatenation, i. e. don't specify mirror, raidz or raidz2 when creating the pool.
