well, if you only have 4 drives for that raid10, I dunno how have a hot 
spare.    if you reserve one as a hotspare, then you only have 3 left, 
raid10's require an even number of drives.   Forgetting the hotspare,

## partition sdc-sdf with one full disk primary partition each, 
parttition type FD (linux auto raid)
mdadm --create /dev/md/myraid10 --level=raid10 --raid-devices=4 
/dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1
mkfs /dev/md/myraid10
mount /dev/md/myraid10 /u01
