# zpool create tank mirror device0 device1 # zpool add tank mirror device2 device3 # zpool add tank mirror device4 device5 # zpool status The last command should show you that you have 3 mirrors in the "tank" pool. Now export the pool from the command line: # zpool export tank REBOOT and then import it through the GUI by selecting Storage>Volumes>Auto Import Volume and picking the pool "tank" from the dialog box that comes up. Hope this helps.
