Your OS install should be able to handle creating the array, .. mdadm is
only required for maintenace - e.g. swapping a drive. For normal
operations, your best friend for softraid is mdstat:

# cat /proc/mdstat
Personalities : [raid0] [raid6] [raid5] [raid4]
md2 : active raid5 sda3[5] sdb3[3] sdc4[4]
      3796322048 blocks super 1.0 level 5, 128k chunk, algorithm 2 [3/3] [UUU]
      bitmap: 0/4 pages [0KB], 262144KB chunk

Three disks, .. three running ([UUU]), raid5, device list.
