Below are few examples of creating DIFFERENT RAID level ZFS POOLS.

Using Whole disks

# zpool CREATE GEEK pool c1t1d0

Using DISK slices

# zpool create geek pool c1t1d0s0

Using Files

# mkfile 100m file1

# zpool create geek pool /file1

Using Dynamic striping

# zpool create geek pool c1t1d0 c1t2d0

Mirrored ZFS pool

# zpool create geek pool mirror c1t1d0 c1t2d0

3 way mirror

# zpool create geek pool mirror c1t1d0 c1t2d0 c1t3d0

raidz1

# zpool create geek pool raidz c1t1d0 c1t2d0 c1t3d0

raidz2

# zpool create geek pool raidz2 c1t1d0 c1t2d0 c1t3d0

raidz3

# zpool create geek pool raidz3 c1t1d0 c1t2d0 c1t3d0 c1t4d0
