I have 5 new disks and I want to build a raid5.
I am think which one is the better method.
1) build normally, so raid will do reconstruction and i probably want to
wait till it ends
2) zero all disks using dd. then build a raid without need to computer
checksum at all since 0xor0=0.
in fact, i am thinking which mdadm command can allow me to do (2)
