Das wird einen Fehler geben...
shl@sonnenkind:~$ pfexec zpool add testpool raidz1 ~/HDD5 ~/HDD6 ~/HDD7 invalid vdev specification use '-f' to override the following errors: mismatched replication level: pool uses 2 device parity and new vdev uses 1
... don't try this at home!

Ja, das ist herzhaft sinnlos so! :-)
Besseres Beispiel:
RAID-Z2 über fünf Festplatten:
shl@sonnenkind:~$ pfexec zpool create testpool raidz2 ~/HDD0 ~/HDD1 ~/HDD2 ~/HDD3 ~/HDD4
shl@sonnenkind:~$ zpool status testpool
pool: testpool
state: ONLINE
scrub: none requested

/export/home/shl/HDD2 ONLINE 0 0 0
/export/home/shl/HDD3 ONLINE 0 0 0
/export/home/shl/HDD4 ONLINE 0 0 0
errors: No known data errors
Weitere fünf Festplatten in den testpool:
shl@sonnenkind:~$ pfexec zpool add testpool raidz2 ~/HDD5 ~/HDD6 ~/HDD7 ~/HDD8 ~/HDD9
shl@sonnenkind:~$ zpool status testpool
pool: testpool
