Hello - can anyone tell me why this:

ReadAhead
Virtual Disk 0

RAID 1

Disk.Bay.2:Enclosure.Internal.0-1:RAID.Slot.6-1
Disk.Bay.3:Enclosure.Internal.0-1:RAID.Slot.6-1

Creates me 2 lovely RAID 1 volumes at the sizes specified?

 

Yet this (eg I JUST want the bigger RAID 1 volume, so i JUST include EXACTLY the same statement for vdisk 1, but put it in place of vdisk 0):

CreateAuto
Unlocked
True
None
Default
WriteBack
ReadAhead
Virtual Disk 0

2
RAID 1
Disk.Bay.2:Enclosure.Internal.0-1:RAID.Slot.6-1
Disk.Bay.3:Enclosure.Internal.0-1:RAID.Slot.6-1



















False

gives me this error:
