    Info: The layout for aggregate "SmallAggr" on node "cluster-01" would be:
          First Plex
            RAID Group rg0, 2 disks (block checksum, raid4)
                                                               Usable Physical
              Position   Disk                      Type           Size     Size
              ---------- ------------------------- ---------- -------- --------
              parity     VMw-1.7                   SSD               -        -
              data       VMw-1.8                   SSD         28.42GB  28.44GB
          Aggregate capacity available for volume use would be 25.58GB.
