(1) Please don't top post.
(2) Command line is possible, but I don't find it easier.  It kind of
goes against the principle we've been following in the rest of the

(3) Back to the bottom for my comment on the previous post ---+

(1) Create a bank of RAID partitions on your disks.
(2) Create the RAID device from the partitions.
(3) Create the LVM physical volume on the RAID device.
(4) Create the LVM volume group on the physical volume.
(5) Create the various logical volumes in the volume group.
