A única "advertência" seria que este comando:
mdadm --create /dev/md0 --level raid10 --name data --raid-disks 4 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
Na verdade, seria
mdadm --create /dev/md0 --level raid10 --name data --raid-disks 24 /dev/sd{a,b,c,d,e,f, and so on}1
Ou melhor
mdadm --create /dev/md0 --level raid10 --name data --raid-disks 24 /dev/sd{a-z}1 Not sure of last one... Give it a try with file creation first... Not much changes here...
