Hi Chris
  Can you please call out the page number in the 11gR2 linux installation guide ?

   However, you would need 3 disks of 1.5G for clusterware (diskgroup for ocr, voting disks etc) and another disk group for everything else(2+ disks in the disk group for normal redundancy). You might create a third disk group for FRA and so on.

   Also, minimal installation can be done with just one disk group too, probably, not a preferred solution for a production environment.
