In un sistema Mac OS X 10.7.5 (Lion) con due unità SATA interne, le unità interne sono collegate tramite un controller Highpoint Rocketraid e sono configurate senza alcun RAID funzionando così in modalità legacy.
Entrambe le unità disco fisso SATA collegate localmente non vengono montate dopo l'accensione del Mac dopo un'interruzione / interruzione dell'alimentazione (spegnimento non pulito). Al successivo riavvio pulito vengono montati i due volumi locali.
Quando l'unità / volume non ha attività di lettura / scrittura, il volume non riesce a montare. Nel caso in cui non ci sia attività I / O sull'unità / volume, l'unità / volume verrà montata.
Entrambi i volumi locali sono identici:

Entrambe le unità hanno uno schema di partizionamento GUID e un file system HFS + identici:
$ diskutil list
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
...
/dev/disk1

0: GUID_partition_scheme *3.0 TB disk1

Come montare automaticamente questi dischi rigidi automaticamente dopo uno spegnimento non pulito?
