mdadm --create /dev/md0 --level=5 --raid-devices=7 /dev/sd[abcdefg]1

The above will create a level 5 RAID named /dev/md0 of /dev/sda1
/dev/sdb1 /dev/sda1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1, with
hot-spare /dev/sdg1

Note: RAID5 is not really recomended for such large disks.  You run the
risk of a complete data loss if one disk fails and the another disk
fails during the rebuild.
