¿Es posible adjuntar un tercer hdd a un espejo ya creado que consta de dos hdds con ZEVO?

Ubuntu

Ejecuto una máquina virtual de Ubuntu con soporte nativo de ZFS. Cuando adjunto el tercer disco duro funciona perfectamente.

OS X Lion

Cuando importo la agrupación a Lion, ZEVO argumenta que falta una agrupación a pesar de que está allí y se vuelve a revisar en este momento.

En Ubuntu:

$ zpool status Toshiba_ZFS

pool: Toshiba_ZFS
state: ONLINE
status: One or more devices is currently being resilvered.  The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.

En Mac OS X (Lion):

$ zpool status Toshiba_ZFS

pool: Toshiba_ZFS
state: DEGRADED
status: One or more devices is currently being resilvered.  The pool will
continue to function, possibly in a degraded state.

Por alguna razón, ZEVO almacena las agrupaciones en / dev / dsk / pero como mi tercer disco duro no es todavía una agrupación y se adjuntará a la agrupación de duplicación de zfs existente, no será reconocido

$ zpool attach Toshiba_ZFS disk3s1 disk2s5
cannot open 'disk2s5': no such device in /dev/dsk
must be a full path or shorthand device name

¿Cómo puedo conectar otro disco con ZEVO?
