È possibile collegare un terzo hdd a un mirror già creato composto da due hdd con ZEVO?

Ubuntu

Eseguo una macchina virtuale Ubuntu con supporto ZFS nativo. Quando allego il terzo hdd funziona perfettamente.

OS X Lion

Quando importerò il pool su Lion, ZEVO sostiene che manca un pool anche se è lì e viene recuperato al momento.

Su 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.

Su 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.
action: Wait for the resilver to complete.

Per qualche motivo ZEVO memorizza i pool in / dev / dsk / ma dal momento che il mio terzo hdd non è ancora un pool e sarà collegato al pool di mirror zfs esistente, non verrà riconosciuto

$ zpool attach Toshiba_ZFS disk3s1 disk2s5
cannot open 'disk2s5': no such device in /dev/dsk

Come posso collegare un altro disco con ZEVO?

Trovato una soluzione alternativa. Dovrai replicare la tabella delle partizioni del dispositivo zpool corrente sul dispositivo che vuoi collegare e poi randomizzare i GUID univoci delle partizioni (dovrebbero essere due). Quindi aggiungi il dispositivo al mirror zpool e formatta lo spazio su disco non allocato su HFS + o qualsiasi altra cosa desideri. Tutto questo accade in Linux con gdisk e parted ma verrà riconosciuto correttamente dalla porta ZVos ZFS di Mac OS X.

… For some reason zevo stores the pools in /dev/dsk/

Nella nuova base di conoscenze ZEVO (2012-09-14), Nomi dei dispositivi disco fornisce la spiegazione.

Una spiegazione comparabile è stata pubblicata quando il complemento di Ten ha venduto ZEVO.

How can I attach a disk to existing zfs zpool mirror with Zevo?

… Ubuntu … When I attach the third hdd it works flawlessly but when I import the pool to Lion …

Nella knowledge base Creare pool ZFS offre tre esempi relativi ai mirror .

Dalle prospettive di ZEVO e OS X, è quasi certamente meglio iniziare le routine relative a ZFS con ZEVO piuttosto che con Ubuntu. Citando dalla Guida rapida per ZEVO Community Edition 1.1:

… ZEVO uses the standard ZFS on-disk format (v28) and is therefore binary compatible with ZFS on other platforms. However, direct interchange with other platforms is not supported in this version. ….

Una nota comparabile è stata pubblicata quando il complemento di Ten ha venduto ZEVO.
