Not necessarily. You could put LVM on top of the RAID device, and
create logical volumes.

Partitionable RAID devices are supported by Linux, but not by the
Anaconda installer. You're better off not using them.

Don't clone the partitions. If you do that, then you also need to
randomize the UUIDs on the destination drive. It's probably easier to
just create the partitions on each disk:
parted -s /dev/sda mklabel gpt \
mkpart primary ext4 1M 200M \
mkpart primary ext4 200M 1224M \
mkpart primary ext4 1224M 100%
parted -s /dev/sdb mklabel gpt \
mkpart primary ext4 1M 200M \
mkpart primary ext4 200M 1224M \
mkpart primary ext4 1224M 100%
