You might find this usefull, text on official CentOS Facebook group. GPT 
is separate from RAID's, so GPT is not covered, but RAID part should be 
the same:

For RAID10 I suggest far 2, and boot regular raid1

Creating Boot RAID1:
[root at kancelarija]# mdadm --create /dev/md9 --level=1 --raid-disks=2 
/dev/sdd1 /dev/sde1 --metadata=0.90

Creating RAID10 far,2:

[root at kancelarija]# mdadm --create /dev/md9 --level=10 --layout=f2 
--raid-disks=2 /dev/sdd9 /dev/sde9
