hi

create raid array

sudo mdadm --create --verbose /dev/md0 --level=5 --chunk=64 --raid-devices=4 /dev/sd[bcde]1

view progress

sudo watch cat /proc/mdstat

create mdadm.conf file

sudo echo "device partitions" > /etc/mdadm/mdadm.conf

sudo mdadm --detail --scan >> /etc/mdadm/mdadm.conf

create filesystem

mkfs.ext4 -b 4096 -e stride=16,stripe-width=48 /dev/md0

index:

tune2fs -o dir_index /dev/md0

e2fsck -d /dev/md0
